Floored People spend a lot of time looking up -- at awe-inspiring stars that have been twinkling at us through the ages, at monolithic mountain ranges that have stood steady for millennia, leafy trees that hold whole eco-systems far above us, or at whatever else it is that takes the shape of our night-time ceilings before our daily departure from wakefulness.


ut too much looking up, especially at the expense of looking around or down, can be limiting and can quite literally become a pain in the neck. So in this issue of Timber iQ, we take the opportunity to unashamedly avert our gaze to the ever-present, all-important floor. And do I have a story about a floor. As a student living in Stellenbosch some years ago, I had the great fortune of sharing a beautiful, but run-down century-old house on campus, which was unfortunately allowed to fall into disrepair. The centre of the house? The kitchen, of course. The floor covering? About eight layers of hideous linoleum. And how many people did it take to remove?

Just one – me – accompanied by my mildly obsessivecompulsive penchant for undoing things – especially ugly floors. I sat on that floor for hours peeling away the layers. Red, yellow, orange, olive green, and also newspaper sheets from a copy of a 1960s Die Burger that carried alarmist messages that were both funny and sad in retrospect. And underneath, my prize, after suffering a dust-induced asthmatic coma, a solid wood floor in exceptional condition. It had to have been there for well over 100 years – worthy of wonder, reverence and hushed tones. That floor, proudly adorned with a vintage whitewashed teacher’s desk for a dining table and knock-off see-through Philippe Starck chairs, formed the epicentre of many raucous dinners, parties, shared hubblies, happy unions, almost-break-ups and an awful lot of bare-foot traipsing. And the thud-thud it emitted when any of us raced to the loo at night, trying to avoid the resident ghosts, was unmistakable. The house still stands (however wonky) today, and the floor has seen many more generations of lively Maties. The floor is the point at which gravity has so firmly decided that our feet shall meet the earth, the place our very toes make themselves at home. In this issue we pay tribute to the floor and showcase just how fabulous this humble platform that draws us all together can be. Speaking of being drawn together, we at Timber iQ wish you a happy and safe festive season, surrounded by family, friends, and of course, good flooring. Enjoy the read!

Season’s Greetings from Timbaclad!


Inviting nature A 24 bed luxury boutique hotel in the heart of Botswana's Okavango Delta, Sandibe Safari Lodge, which draws aesthetic inspiration from the pangolin, treads lightly on its sensitive environment. Images by: Dook Photography




he Okavango Delta is considered one of the seven natural wonders of the African continent. Since the original lodge was built seventeen years ago, it has been declared a world heritage site and in consequence, a raft of wholly appropriate, but formidable restrictions have been imposed on building there. The design of Sandibe not only meets these challenges, but is invigorated and inspired by them. It is habitation made manifest of all the creatures that have ever found or made shelter in and beneath the site’s ancient trees. The lodge draws its inspiration from animals that carry their shelter with them or weave it from the organic materials to hand. The pangolin – Africa’s armadillo – was chosen as a specific motif because of its shy, elusive and completely harmless nature, and its ability to curl into its own protective carapace of scales. The final building appears to have grown organically from its riparian site or, metaphorically speaking, to be some endemic, gentle and maternal creature leading her offspring through the swamp forest.

The lodge draws its inspiration from animals that carry their shelter with them or weave it from the organic materials to hand. The pangolin - Africa's armadillo - was chosen as a specific motif because of its shy, elusive and completely harmless nature, and its ability to curl into its own protective carapace of scales.


Although LEED or Green Star rating tools have not been developed or applied to this sort of building, the project proceeded on the basis that if they were, the highest standards of accreditation would be aimed for. The sustainability imperatives of the project were: • The new buildings had to be wholly built of ultimately bio-degradable materials. • The site, separated from civilisation by a hundred miles of swampland, river crossings and rough tracks, had to be completely cleared of all previous non-degradable material – literally hundreds of tons of demolished bricks and mortar gently removed from the forest and trucked out of the delta. • 70% of the luxury lodge’s not insubstantial energy requirements had to be of sustainable origin. • Minimal to zero physical impact of any sort on the site, fauna and flora. • Complete treatment of sewerage and removal of waste. Notwithstanding the above, the client expected a boutique hotel that would deliver the very highest standards of luxury to its well-heeled and well-travelled guests. Essentially this meant, in addition to unique and inspiring design, there could be no compromise on power, copious hot water supply, luxury bathing and food preparation equal to the best hotels in the world. The sorts of compromises that inform most eco lodges were not acceptable. The completed project meets or exceeds all of the above imperatives.

Sandibe is built almost entirely of wood. Laminated pine beams give curvilinear shape. The building skin is formed like an inverted boat from layers of butt jointed pine scale planks; waterproofed with an acrylic membrane and covered in Canadian cedar shingles. There is no glass other than in the retail shop and library, the ‘glazing’ such as it is, is Serge Ferrari Soltis fabric, a permeable but highly weather resistant and thermally efficient membrane. External screen walls and balustrades are fashioned from an interlocking mat of eucalyptus laths woven onto stiff wire, and decks and floors use FSC approved hardwoods.

Sandibe is built almost entirely of wood. Laminated pine beams give curvilinear shape. The building skin is formed like an inverted boat from layers of butt jointed pine scale planks; waterproofed with an acrylic membrane and covered in Canadian cedar shingles. Power is sourced from a 100 KVA PV array that means generators need only run for three to four hours a day. Hot water is delivered instantly, even at the furthest cabin from a solar array of evacuated tubes backed up by heat pumps continuously pumped through a 2.5km ring main. Notwithstanding the distance, the measured loss of temperature between source and furthest tap is 1.7 degrees. All water and soil waste is collected and pumped through an accredited biological treatment plant that renders effluent certifiably safe for discharge into the highly sensitive environment. Finally, the environmental success of the project is perhaps best judged from the fact that the area’s prolific wildlife, including big animals, like elephant, hippo, lion and leopard, have continued to live on and use the site with such disregard for the emerging and completed buildings that you might imagine they simply don’t see it at all. As IM Pei said, “Good architecture lets nature in.”

Pressure Treated Timber Timber with a moisture content below 20% cannot rot. This may not always be possible when used outside in exposed conditions as it requires proper application and maintenance of a suitable penetrating and water repellent wood sealer. The options are to use either naturally durable but expensive exotic hardwoods, or less costly locally grown non-durable Pine or Eucalyptus (gum) timber or poles, that have been pressure treated with a suitable wood preservative to the desired exposure or hazard class.

The H class system is a guide to help you buy the correctly treated timber for your project. Be sure to look for the required H class on the timber as well as one of the two quality marks given below.

Sustainable Timber Resource Timber is the most sustainable building product available to man. It’s naturally renewable. Over 90% of plantations grown in South Africa are FSCTM certified.

Hazard classes: H2— dry interior above ground H3— exterior above ground H4— in ground contact H5— in contact with fresh water and wet soil H6— in contact with marine waters

Biligom International poised to take structural timber market by storm ®

With the sound endorsement of industry experts, Biligom is ready to take its national and international market share of structural timber to great heights.


looming national timber shortage facing the construction industry today, and the fact that it takes around 30 years to grow a suitably mature pine tree for construction purposes, means that it will take this long to meet the country’s needs, provided someone starts doing something about it now. Sadly, this is not happening and the industry can expect the situation to worsen steadily.


DECEMBER 2014 / JANUARY 2015 //

Alternatives have to be found, and quickly, too. To this end, and in line with the country’s future needs, Biligom® International (Pty) Ltd has come up with a registered patent for processing moist Eucalyptus timber that has the potential to turn this issue into a short-term solution for a long-term problem with significant benefits along the way.


The Biligom® process was launched to great acclaim earlier this year and comes with solid industry backing from various sectors. The Biligom® process has been underpinned by research conducted by Philip Crafford, MSc Forestry graduate from the Faculty of Agri Sciences at Stellenbosch University, under the mentorship of Prof. Brand Wessels, with the findings presented in his thesis entitled, ‘An investigation of selected mechanical and physical properties of young, unseasoned and finger-jointed Eucalyptus grandis timber.’ The study included research into the Biligom® product under wet and dry conditions, with a focus on the product’s physical properties, testing for strength and flexural properties, concluding that it is suitable for use in moist form as a structural timber, and that it exceeds requirements for this application. Biligom®, backed by testing and research conducted through Lonza Wood Protection and specially treated with Lonza’s Tanalith E under specific conditions, is a game changer in terms of how Eucalyptus can be used as structural timber. Truss strength values have been assessed by MiTek, who endorse Biligom®. MiTek have also created suitable software for Biligom®, for truss fabrication. The Biligom® process has also been audited and awarded full accreditation by the South African Technical Auditing Services (SATAS). Biligom® is also backed by the Institute of Timber Construction for South Africa (ITC-SA), an association which regulates the structural timber industry in South Africa, and which plays a pivotal role in the final sign-off of engineered roofing and building structures. The Biligom® process is endorsed by both financial and various other institutions, adding further to its investment appeal.

ADVANTAGES: • Structural and strength properties are backed by academic research conducted at the University of Stellenbosch. • Eucalyptus growers need to supply 5-8 year-old timber, significantly relieving the long-term pressure for more Pine plantations. • Biligom is graded to S7 specifications, meaning that around 28% less timber is required than Graded S5 Pine to cover the same roof area. • Roof truss fabricators can expect to use approximately 40% fewer gang nail plates for Biligom than for S5 Pine. MiTek Industries SA have designed software to cater for this in their roof truss designs. • Biligom is treated to H3 SANS 1288 specifications and is sold at prices comparative to S5 Pine. • Biligom is elegantly suited for low-cost housing developments. • By using Tanalith E for treating Eucalyptus, Biligom carries a very small environmental impact and the resource is infinitely renewable. • Biligom® International is currently negotiating license agreements with interested parties to produce Biligom® throughout Southern Africa. The response has far exceeded expectations

SIZES CURRENTLY AVAILABLE: • ˚38mm x 38mm/50mm/76mm/105mm/152mm and • ˚50mm x 76mm/152mm

LENGTHS ARE: 3.6m/4.2m/4.8m/5.4m/6m/6.6m In just a short time, the Biligom® product has been embraced by the market and has enjoyed significant buy-in from truss manufacturers and various other sectors. Biligom® International is uniquely positioned to supplement the structural timber market with high quality structural Eucalyptus graded to S7 specifications, supported not only by a growth time of between 5 and 8 years and similar pricing to structural pine, but a list of highly impressive endorsements.

// DECEMBER 2014 / JANUARY 2015



LOOKING AHEAD -- BILIGOM® 2015 VISION: Building on the rapid uptake of the Biligom® product, as well as its exponential market share growth, Biligom®’s vision for 2015 is to continue to service the market with a quality product that speaks for itself, focusing on its reputation for business integrity and customer service levels.

Technology of glued solid wood for bearing purposes By: Eliška Oberhofnerová

WOOD AS A BUILDING MATERIAL Due to its availability, relatively simple processing and mechanical properties, wood is one of the oldest materials used in construction. Thanks to these undisputed advantages, timber structures have been constructed in almost all cultures and in all stages of development of human society. Wood was primarily used for building the simplest human settlements intended to protect inhabitants from external dangers. With the gradual acquisition of knowledge about the material’s properties and increasingly sophisticated tools and machinery, timber construction became more complex and took the shape of bridges, railways, roofs, and multi-storey buildings.


DECEMBER 2014 / JANUARY 2015 //

The knowledge and understanding of the properties of timber are a prerequisite for its successful use in construction, and by constantly examining these properties, new materials, which overcome the challenges that can come with using timber in construction (dimensional changes in response to variations in humidity, limited size, directional properties, flammability, presence of natural defects and possible biological pest attacks), are being developed. This development is closely connected with that of of manufacturing technologies, fasteners and adhesives.


DEVELOPMENT OF GLUED SOLID WOOD The technology of glued solid wood is significantly applied in the area of bearing wood structures, and dates back to the 19th century, when the first construction using glued laminated wood, as we know today, appeared in England. Otto Hetzer, who in 1906 acquired the patent for glued laminated beams composed of two or more lamellas (glued according to the parallel wood fibres), is considered to be a pioneer of this technology. With Hetzer´s construction method, one no longer had to stick to the length or cross section requirements of the component imposed by the nature of trunk diameter. The technology of gluing allowed for the use of even fewer dimensional elements and to combine them into one, as well as minimizing timber’s propensity to twist. This discovery marked a new era in timber construction.

Visit us at our Showhouse in Bellville and find out innovative ways to spruce up your home!

Great progress was also achieved in the area of adhesives. Until the early ‘50s casein adhesives were used. The resorcinol-formaldehyde adhesive, which does not lose its properties even in humid conditions, was a significant discovery in the area of glued timber. Since then, it became possible to use glued wood profiles outdoors. The use of melamine-formaldehyde adhesives was another important development. Currently used adhesives do not contain free formaldehyde, but some of them have additional bond formaldehyde. In the 1940s, finger jointing, which ensures sufficient elasticity, was also developed. It is still used for longitudinal connections of bearing elements. The current technology supporting the manufacture of glued solid wood is in accordance with the stringent requirements of European standards. Close attention is paid to the input material, to the production process, as well as to the final method of application. The input material designed for the production of glued solid wood is chemically untreated wood (coniferous trees, mostly spruce) from forests that are certified by the Programme for the Endorsement of Forest Certification (PEFC).



You can find our products at the warehouse of our Distribution Partner 
 Ian Fuller Agencies in Cape Town.

High-tech CNC machines are used, ensuring both accuracy and speed in production, and connect particular machined, dried and defective divided elements (lamellas), which are longitudinally connected by finger jointing. The lamellas are then given a layer of adhesive and are bonded under high pressure. This method of gluing preserves the wood from possible damage.

The wood does not lose strength as it is bonded with carpentry joints, the strength of which are required to be higher than the strength of the wooden material itself. This means that during the stress of glued joints it is the wood surrounding the join itself that should separate and not the joint itself. Ecological adhesives with no health risks are used and regulations concerning material producers and manufacturers of wooden buildings have to be obeyed. Nowadays, glued wood has reached high load bearing capacity and can span several times the distance that solid wood can. Glued wood exhibits excellent dimensional stability, improved fire resistance and is aesthetically pleasing.

GLUED SOLID MATERIALS FOR BEARING PURPOSES Konstruktionsvollholz (KVH) structural timber, duo and trio laminated beams, glued laminated timber and cross laminated timber (CLT) can all be categorised as glued solid wood for bearing purposes. • Konstruktionsvollholz (KVH) structural timber KVH is a structural timber made of four-side cut profiles of coniferous wood which have been longitudinally connected by finger jointing. These profiles are removed of defects and kiln-dried to 15% moisture (± 3%). Thanks to the method of cutting used and the low moisture content of the material, the final product has a reduced propensity for cracking, is dimensionally stable and, subject to due observance of the rules relating to the structural protection of wood against biological attack, can also be used without the need for wood preservatives. Lengths of up to 16m can be attained with KVH structural timber, which is most often used to support the construction of frame buildings, ceiling beams or truss structures visible from the interior. • Duo/trio laminated beams Duo/trio laminated beams are industrially manufactured products made of either two or three lamellas glued together at their flat sides with the fibres running parallel. The lamellas are glued in a position opposite to their natural position in the trunk to acquire better dimensional stability. This dimensional stability and low moisture content make duo/trio laminated beams particularly suitable for the construction of timber houses. The classic character of the beam and appearance of solid wood are well preserved. Duo/trio laminated beams’ range of applications is similar to KVH structural timber, and they also boast excellent characteristics as a building material for exposed ceiling beams and rafters. • Glued laminated timber (BSH) Glued laminated timber is a bearing element formed by

gluing at least two parallel wooden machined lamellas. The glued joint does not have any negative influence on the mechanical properties of the wood and the element of glued laminated timber is statically assessed as a compact profile. Among the most significant benefits include the exact shape, dimensional stability, surface quality, strength classes according to standards and arbitrary dimensions of the beam. Elements of glued laminated timber are designed for statically loaded wooden structures, such as roof trusses, joists, girders, beams, columns and construction of bridges and footbridges. Modern glued laminated timber, a technologically demanding product, has established itself as a building material, especially for buildings with large span lengths over 100m.

• Cross laminated timber (CLT) CLT panels are made of dried coniferous lamellas (about 8%) compounded into an odd number of layers which are mutually perpendicularly rotated and glued under high pressure. This ensures dimensional stability of the panels during humidity changes. Melamine-ureaformaldehyde adhesives without free formaldehyde and polyurethane adhesives (formaldehyde-free, which is approved by European standards for construction of load-bearing wooden building components for interior and exterior applications) are most commonly used. CLT panels do not burden the environment with harmful emissions during the manufacturing process, and create a pleasant microclimate that has a positive effect on human health. Modern CNC machines are used for cutting the wood, and with the use of insulation materials with low diffusion resistance, a vapour permeable building envelope without a vapour barrier is achieved. The most significant advantage of this system is the simplicity of the design, the minimum number of joints, fire resistance, short period of construction (several days) and the possibility of having exposed solid wood in the interior. CLT panels are used for the surface structure of walls, ceilings and roofs.

REFERENCES: FUTURE POTENTIAL The requirements for construction are related to the increasing level of technology of wood materials. Dimensionally stable, accurately machined and dried timber is required. With the development of fully automatized production controlled by computers, using adhesives and protective substances, together with the increasing popularity of wood structures, glued solid wood for bearing purposes has virtually unlimited potential in the field of construction. konstrukce/594-konstrukni-system-ktery-posouva-hranice

Coricraft Cape Town invests into AES Extreme CNC nesting machine from the CMC Group As the leader in CNC sales in nesting applications in the southern African market, as various clients can attest to, the CMC Group has answered the demand by medium and high production capacity companies to introduce a more cost-effective solution from Europe with this successful product range.


uring the introductory meeting with Coricraft’s CEO, Craig Schneeberger and Coricraft Cape Town production team managers, Paul Boden and Eugene Snyman, the complete high production nesting-based operation was conducted at CMC Group’s premises in Johannesburg, and Coricraft production components were manufactured according to specifications. According to Deon Olivier, General Manager of the CMC Group, “We are committed to ensuring the correct components and

software on these models, and with the first machine arriving this month, it will certainly please our clients and uphold the CMC Group’s reputation in the industry.” The AES group of companies manufacture a complete range of high spec CNC equipment and cater for an all-round production solution. The Coricraft AES weighs in at 5.7 tons and this solid stability sets the benchmark for stable axis flow and isolates any subsequent movement during axis rotation and cutting cycles.


The CMC Group offers its clients a complete turnkey solution from the complete high pressure dust extraction system to tooling and additional software solutions, minimising the setup costs by including delivery and rigging, as well as installation and set-up, relieving the customer of unnecessary installation stress. All CMC technicians are fully trained by the company’s suppliers in Europe to provide a functional changeover for all clients. Coricraft’s Paul Boden and Eugene Snyman, familiar with CNC production and operations, already had the CNC design programming down to a fine art.

Clifford Art from the CMC Group. The AES Extreme 2142 nested base solution is powered by a 9kW HSD electrospindle, with the option of a 12kW HSD electrospindle available for more durable material processing, and the aluminium bed, renowned for its durability, is a standard feature on this unit. The machine is driven by Alphacam advanced software and is controlled by Osai controlling software, with the latest CAD/ CAM software completing this powerful designing package. The latest in software on the market regarding a fluctuating Z-axis to produce diamond and wave doors will be a standard on the advanced package from Alphacam and will also have a pendant control for hands-on operation during production, as well as vertical drilling applications. This model will suit the shopfitting, office furniture and flatpack manufacturing sectors of the industry, and kitchen component and wrap door manufacturers will be spoilt for choice with the versatility of this model. Most machinery from Europe is almost 60% more costly, and also does not cater for all the options and performance levels this model of machine can offer. It comes with twin 250m3 Becker vacuum pumps built independently on their own stand to eliminate the current dust and airflow problems experienced with most CNC machinery. The high-end switchgear, Siemens inverters and PLCs on this machine complement the overall high technical standard of this machine. On this specific model, Coricraft opted for the high-end machine solution and the CMC technicians in Cape Town, headed by Clifford Art and Sales Director for the CMC Group, Cecil Schickerling, implemented the installation and requirements needed for phase two, which consisted of the start-up and running of the machine. Due to multiple component programming, CMC senior technical manager, Rob Smart, assisted in fine tuning the production schedules and training on the AES machine. This is the first AES model for Cape Town, with another en route to the Western Cape before year-end.


DECEMBER 2014 / JANUARY 2015 //

The CMC Group is excited about these early sales into this competitive market. The initial idea from CMC Group CEO, Pieter Olivier and Sales Director, Cecil Schickerling was to get at least one into each province before year-end, as in this industry word of mouth is a key element to ensure future growth for this product. With four units installed in Kwa-Zulu Natal and another two on the way to Gauteng and Botswana, CMC General Manager, Deon Olivier will oversee the installations with his technical team in these regions. The boom in the last three months in the Western Cape certainly bodes well for a fantastic year in 2015, where this machine will definitely establish itself as the leader in CNC machinery for the woodworking industry. The AES machine will be on display at WoodEX for Africa in Johannesburg midway through 2015, where other exciting products from the CMC Group will also be on display.

The CMC Group would like to thank Craig Schneeberger from Coricraft and his fantastic team for the trust placed into us in purchasing this machine, as well as Dave Cummins from Atlantic Cape for assisting all parties with his vast manufacturing knowledge during the procurement stage.

The CMC Group will continue to provide excellent service and support to Coricraft to ensure high production rates on all their quality furniture manufacturing, and will make every effort to build on this well-established relationship.

his unique space was designed as a research and development studio for and within a textile company’s headquarters, and the design concept was based on the physical interactions among the users (R&D personnel), products, accessories, and the materials. The project came about as result of observing the day-to-day workings of the R&D office space. The actions of sitting, walking, working, and evaluating the products in ordinary levels and locations of the office were found to be limiting in the research and development process. A new, more dynamic space was required. This new space needed to acknowledge the flexibility of working in motion, with easy access to the whole volume of space, rather than as limited an area as possible. The design concept was based on the suggestion of establishing a platform that makes it possible to expand on the use of space during work, rather than, like a desk space, confining it to a certain area, and also limiting accessibility.

"We aimed to free the actions of sitting, working while in motion, learning, meeting, easily accessing the hangers, and observing the products (denims, fabrics, accessories, etc.) from different distances, instead of defining the locations of the actions. It was intended to increase and diversify the interactions of the users - both with each other and the space."

MOISTURE-RESISTANT, LONG-LASTING, AND QUICK TO INSTALL In addition to the multitude of designs, technical features and the various application options of the new laminate flooring, floors with aqua+ technology are available for the first time in an EGGER collection. EGGER flooring with aqua+ technology is moisture resistant and thus can be used in wet rooms, including the bathroom. "This new product group opens up new possibilities in both the private and the commercial areas," says Johannes Eder, EGGER Sales Representative, Africa. The longboard is another novelty in the range of products available. The ‘long’ format (2 052mm x 248mm) meets the requirements of the still-reigning trend towards open living. The board character of the long format is in particularly high demand for rooms that seamlessly merge with each other.

Last, but not least, the new collection is also comfortable for the installer. The fold-down installation system, ‘Unifit’ patented by Unilin guarantees a very simple and significantly faster installation.

EGGER LAMINATE FLOORING 2015-2017 • New laminate flooring collection with 70 décors per region • Motto: Always up to date • For sample requests please refer to the EGGER partner in South Africa: Azura Distributors (t) 021 534 0870 • Technical highlights: aqua+ technology (moisture-resistant laminate flooring), longboard, Unifit installation system, authentic surfaces.

A lot of development work also went into the surfaces of the floors. The trend towards authentic textures, perfectly aligned with the décor, continues to dominate. Textures with a pleasant feel, such as Authentic, Barrique, Vintage and Grand Canyon, belong to the anti-slip class R10, which provides the end user with safety, living and walking comfort, and easy cleaning. In addition, the fact that there is no décor repetition in the package means that the final look is in no way inferior to real parquet.

Cleaning, maintenance and installation guidelines for laminate flooring Insight from the Southern African Wood, Laminate & Flooring Association (SAWLFA) GENERAL CLEANING AND CARE: General care and maintenance of laminate flooring includes the primary measure of cleaning. It is important to wipe up any spills immediately with an absorbent cloth or towel, and to regularly remove dust with a broom or vacuum cleaner. Periodically make use of specially formulated cleaner/ restorer to maintain the lustre and allergy free surface of the floor. Make sure that the cloth or mop is only slightly damp, as excessive water may damage the floor. Rather use a dry mop and spray a recommended laminate floor cleaner onto the mop or wipe the floor with a well wrung damp or moist cloth. Special laminate flooring mops are available from most reputable flooring suppliers. Do not sand, varnish, polish, or wax the floor, or use any abrasive cleaners, as these treatments will adversely affect the floor. Do not try to clean grooves with a pointed metal object.


DECEMBER 2014 / JANUARY 2015 //

Also, do not place pot plant drip trays directly onto the floor’s surface – always have these lifted off the floor by at least 50mm to allow airflow under the pot plant. Long-term wear and tear is caused by dirt walked onto the floor from the outside. Walked-in dirt, such as gravel and sand, acts like sandpaper and can cause unpleasant scratches. To prevent this, place large doormats at all entrances. Felt pads fitted under the feet of tables, chairs and cupboards are also recommended, making them easier to move around and preventing any scratching. In the same vein, equip office chairs, filing trolleys and mobile containers with castors, or rollers with soft treads, and replace any existing old, hard, or sharp-edged castors with the same. Direct sunlight may cause fading of the laminate floor, so ensure that all doors and windows have UV filters, blinds or net curtains.

• Glue or nail profiles that will prevent the natural movement of the floor. • Leave a room unoccupied with no curtains. • Drag furniture across the floor. • Wet the floor.

STAIN: Fruit, berries, milk, beer, wine, tea, lemonade, urine, blood, chocolate, grease, cooking oil, rubber smears, shoe heel scuffs, dirt from the street, coloured pencil, oil crayon. REMOVAL: Wipe off immediately with an absorbent cloth. If dried, use a suitable laminate cleaner and dry wipe afterwards. STAIN: Nail polish, shoe cream, varnish, lubricating oil, tar, felt tip pens, ink, mascara, lipstick, carbon paper. REMOVAL: Wipe off with cloth soaked in solvent, like acetone or concentrated vinegar, laminate stain remover. Use sparingly in each case and only in the area of the stain and dry wipe afterwards.

When selecting the appropriate type of laminate to be used in any specific area, special attention must be paid to application requirements, abrasion Classification (AC) = AC1 to AC5 – AC1 being the softest or least wear resistant and AC5 being the hardest/most durable. Domestic applications require the use of AC3 31 – AC4 32 for longer lasting durability. For example, the AC5 is used in shopping centres. Below are the testing tables used and how we identify the usage for a floor:

Test a small area first to avoid damage, i.e. discolouration of the lacquered surface. Ammonia-based cleaners and detergents must not be used, as these can damage or discolour the sealant surface.














For more in-depth details consult the SANS 10043:2009 manual.

All the support you need Knowing that the trusses overhead have been designed and erected according to industry norms and standards is of the utmost importance, as is the implicit trust home owners and developers must have in the professionals they employ to ensure the correct design and erection of this important structural component. By Lyndsay Cotton, General Manager of LCP Roofing and Chairman of the ITC-SA with assistance from professional engineer, Errol Hobden.


he word ‘truss’ comes from the very old French word ‘trousse,’ which meant ‘an arrangement or group of objects bound together.’ From an engineering perspective, a truss is a rationally designed framework of structural compression and tension members, arranged in a series of triangles in order to span large distances, and to support the dead and live loads to which it will be exposed during its lifetime. The truss rests on a wall plate, which is a horizontal loadbearing member (the support) of an engineer-approved dimension, of a material fit for the design purpose, and which must be able to transmit the design loads to the supporting structure. This wall plate can, for example, be of structural timber or steel.


DECEMBER 2014 / JANUARY 2015 //

The connection of the truss and wall plate is thus engineered by nature, and it is this connection that is often overlooked by the designer and erector. The roof truss designer is to ensure that all structural loads are catered for in the design of the roof trusses. This will ensure that dimensionally correct members are used to accommodate for all the forces that could be applied to the roof structure of the building, transferring into the supporting structure below. The incorrect design of the roof trusses and their connection to the supporting structure could cause excessive deflections at the heel supports of the trusses, which could result in wall cracks and the potential failure of the structure.


Take a masonry wall support in a standard residential application where the wall is designed to support vertical loads imposed on it by the roof structure: The wall is designed as a compression member able to resist vertical loading, but in most cases will not be able to resist excessive horizontal movement or forces. The wall designer needs to ensure that the wall is capable of resisting the horizontal loads imposed on it by the roof structure.

SUPPORT TYPES AND SUPPORT REACTIONS When considering supports and reactions, the following graphic explains best the three typical constraints and forces experienced in a structure, namely ‘roller’ supports, ‘pinned’ supports and ‘fixed’ supports.


Roller The connection point on the bar cannot move downward.

Pin The joint cannot move in vertical and horizontal directions.

Fixed Support The support prevents translation in vertical and horizontal directions and also rotation.

// DECEMBER 2014 / JANUARY 2015




Trusses are mostly designed with one pinned support and at least one roller support. From a design calculation point of view, the roller support will allow the truss to move horizontally; therefore the truss design needs to ensure that the truss is stiff enough so that the horizontal movement is kept to a minimum or within acceptable design standards. When a truss is designed with one support pinned and the other support as a roller support, the design calculations will show that there are no horizontal reactions.

H - Overall height of building Hx - Horizontal displacement for storey height u - Overall horizontal displacement ux - Horizontal displacement over storey height

All structural members deflect under load and the horizontal deflection in a roof structure is an important facet to be considered in the design of the support structure. SANS 10160-1:2010 recommends that the horizontal deflection in a wall or column be no more than storey height of the element divided by 250. For example, a typical residential supporting wall of say 2 800mm high should not deflect horizontally by more than 11mm. When designing roof trusses and especially scissor trusses, quite often the horizontal deflection will exceed 11mm. Should this deflection exceed 11mm and be no more than 25mm, a sliding shoe must be installed on at least one support in order to allow the truss to deflect without imposing excessive horizontal loads onto the supporting structure.

There will be instances where the truss designer will be required to pin the truss at both supports. This should only be allowed with the approval and consent of the design engineer. By pinning both supports, the roof truss is then dependent on the supporting structure, as well as the connection of the truss to the support structure for its strength. The truss is no longer a single structural member that is capable of supporting its load on its own, but is now dependent on the supporting structure to help it carry the load. The supporting structure must thus be able to withstand all the forces, as well as the horizontal forces imposed on it by the roof structure. The structural engineer responsible for the design of the support structure needs to be contacted to find out if he has accommodated for the loads and horizontal loads that the roof will be imposing on the support structure. The truss engineer and the engineer responsible for the support structure need to liaise on the design of the cleat required to anchor the roof trusses to the support structure. In some cases the trusses may be required to resist axial loads. These axial loads could be due to wind or seismic loads and in some cases they could be due to other structural components in the structure needing help from the roof trusses to resist, for example, excessive buckling loads. In these cases it is imperative that the connection of the roof truss to the structure be adequate to transfer the loads from the one structural component to the other. It is important to note that wire ties or strapping cannot be considered to adequately transfer horizontal loads into the support structure. Wire ties or strapping are designed to resist upward forces generally created by wind.

SUPPORT OVER OPENINGS Vertical support is equally critical, and whilst this is not within the ambit of the truss designer’s responsibility, it is the duty of care of the truss designer to notify the engineer of unusually large loads imposed on a supporting structure by the roof trusses. (One of the least understood construction details on a building site is that of the support of roof structures over double garage openings.)

According to SANS 10400-K:2011 the lintel depth over a double garage opening should be no less than 765mm or 9 courses of 85mm deep each, and should be of a grouted cavity construction, the cavity filled with 25MPa concrete.

A correctly constructed lintel will adequately support the roof structure and be able to resist both vertical and horizontal forces.

Pre-stressed concrete lintels must comply with SANS 1504 and the bearing width (each side of the opening) must be no less than 350mm. In other words, the pre-stressed lintels over a typical 4 800mm double garage opening are not to be less than 5 500mm long and are to be supported for at least 7 days after completion. Furthermore, it would be wise to introduce a camber of span/500, which, rounded off, equates to 10mm. This is easily accomplished by installing the lintels and building up the ends with brickwork to weigh them down. The lintel is then jacked up centre by 10mm and the brickwork completed.


There must be a minimum of 2 x Y12 primary reinforcing bars at the base of the lintel and 1 x Y12 secondary reinforcement at the top of the lintel. Brick force centres should not be less than 200mm. The use of 5.6mm harddrawn wire introduced in lieu of brick force over all openings will be the preferred method employed by all professional builders. The brickwork must also be completed in one shift.

Double up New Carne on Kloof, designed by Inhouse Brand Architects, extends the original Carne on Keerom to a wider audience.


arne on Keerom Street is a favourite amongst discerning Capetonian diners. So much so, that its ongoing popularity meant that celebrity chef, Giorgio Nava, was constantly turning away prospective customers from an already-full restaurant. Because of this, Nava approached Inhouse Brand Architects, the design team behind all of his projects, to design a second branch of Carne – the now equally bustling Carne on Kloof. Aidan Hart, the Creative Director of Inhouse, focused on mirroring the quiet design elements of the original Carne on Keerom Street, while preserving the existing architectural features of the new Victorian locale, to create a proud extension of Nava's authentic Italian gastronomic philosophy. For the original and first Carne, Inhouse focused on creating a warm and simple reincarnation of Milanese élan. For Carne on Kloof, Inhouse kept to this same 'blueprint' by using natural design elements. Raw Orgeon pine clads the walls of this inviting space and exposed brick walls act as a textured signifier. Intimate lighting – again a feature of Carne on Keerom Street – reinforces the romantic spirit of this environment.


DECEMBER 2014 / JANUARY 2015 //


Additional notes of warmth are woven through the space by preserving the original Victorian fireplace, timber floors and high ceilings. These authentic touches are complimented with quality finishes. A marble and steel bar monopolises the back section of the restaurant. High-back barstools, cushioned in animal hide, flank the expansive bar area, and are in keeping with the earthy materials that abound. Moody, mottled-grey accent walls give the space texture and depth. The passionate flair of Italian culture is injected through a burst of deep red on a shelving unit that feature Nava's personal collection of antique copper vessels and an impressive wine collection. Inhouse determined that an understated design intervention was the ultimate paean to Nava’s personal style and his successful brand of genuine Italian dining. The result of Hart's strong design partnership with Nava is the creation of elegant, unpretentious space that will leave clients wanting more of Carne’s absolute celebration of European quality and essence.

A roofing solution with umbrella benefits Introducing a lightweight roofing material with a heavyweight reputation to South Africa


ny builder worth his salt will tell you that ecoawareness is playing an ever-increasing role in the minds of the South African public.

Roofers utilising innovative Onduline® products can rest assured these materials more than live up to their green credentials. The global leader in lightweight roofing solutions, Onduline® is a company which originates in France and recycles some 200 000 tons of material each year.

Another primary consideration when buying roofing materials is aesthetics, and the company’s tantalising new release, likely to take the South African market by storm, is the Onduvilla® tile, which includes an artfully shadowed 3-D Mediterranean terracotta clay tile look. Indeed, the Onduvilla® tile caters to a variety of preferences, with colours available, including red, green, brown and black.

This diversion of waste from landfills diminishes the extraction and processing of raw materials, which in turn lowers energy consumption, reducing pollution.

Onduvilla® tiles are smaller than the Onduline® sheeting option, at only 107cm x 40cm. A total of 3.23 tiles are needed to cover one square metre and at 4kg per square metre, Onduvilla® is fantastically lightweight, making it a canny solution for homeowners who prefer a long-lasting, authentic-looking tiled effect. An added benefit for contractors is that this lightweight material is surprisingly easy to hoist to roof level. An uncompromising, full roofing solution, which is celebrating 70 years in the global marketplace of constant striving to improve its sustainable products, the Onduline® selection encompasses not only Onduvilla® tiles, but also Onduline® roofing sheets and Bardoline® shingle tile strips. Comprised of organic cellulose fibres impregnated with bitumen and natural mineral pigments, its products are subjected to intense heat and pressure, and coated in resin, ensuring guaranteed durability, even in harsh seaside climates, with a 15-year waterproofing guarantee. In keeping with the green theme, Onduline® products have outstanding insulation properties, which allow for cooling during our hot African summers and retention of heat in chilly winters. Excellent acoustic insulation properties also mean Onduline® has been used in sound studios and cinemas for soundproofing. Anyone who has ever tried studying in rowdy conditions can imagine the extreme discomfort of being educated in a typical rural South African school structure. Here, a dramatic African thunderstorm would muffle even the most strident teacher’s instructions and temperatures might range from searing highs to finger-numbing lows. Clearly then, schools, sports halls, as well as hospitals churches, warehouses and homes could all benefit from these excellent thermal and acoustic insulation attributes. The insulation perks, as well as overall aesthetics and the fact that the tiles are far less susceptible than materials such as thatch, to gecko infestation (and the associated waste clean-up), are just some of the many reasons why home owners are increasingly turning to Onduvilla® as an alternative to conventional roofing methods and thatch.

Recently, local thatchers have seen the development of a trend away from thatch. This can be ascribed to the fact that: • Some thatched homes are situated in less than ideal locations. Thatched roofs, particularly in coastal zones with high humidity, and those shaded by overhanging trees which cannot be removed, and which prevent the roof from drying out effectively, can often succumb to rotting. • The limited lifespan of thatch necessitates replacement of such on average every 25 years, or less, but many homeowners are simply not in a financial position to do this.

But a correctly built thatch roof instils an undeniably rustic charm, particularly suited to South Africa’s bushveld and berg surrounds, which is why some clients request the oversheeting option, allowing their homes to maintain the look and feel of thatch inside, whilst protecting the outside thatch surface from exposure to the elements and consequent deterioration or rotting. The oversheeting method can really only be used in specific cases when the thatch is in an excellent condition and not rotting or full of dust. It would be a terrible risk to oversheet thatch if it were not in good condition. In most instances, however, homeowners have been delighted with their decision to convert wholly to Onduvilla® roofing. Here, the thatch ceiling method may be employed to maintain the thatch look and feel internally. The roof is stripped bare and a new layer of thatch is laid under insulation, using the original poles and laths. A major plus is that this new thatch is kept pristine as it is not open to the elements, so there is no rotting or dust fall.

Before One of the advantages of thatch is that it creates a visually appealing roof with delightful contours and curves. But this contouring can be tricky to convert to alternative roofing solutions, since the existing thatched roof structure is usually built from CCA-treated gum or Eucalyptus poles. Because they have not been machined, as would normally be the case for roof trusses, each pole differs slightly, with varying widths and knots in the wood, and this must be taken into account along the entire length of the pole. Cintsa Thatching, a member of the Thatcher’s Association of South Africa (TASA) – which has 15 years of experience to its name, has been approved as a supplier and installer of Onduvilla® and Onduline® roofing in the Eastern Cape. The company said its clients had long been seeking a premium roofing solution suited to coastal areas, which was flexible enough to accommodate the original thatched roof design and structure. Responding to this need in the roofing market, CEO of Cintsa Thatching, Jonathan Bosazza, pioneered the use of Onduvilla tiles in thatched roof conversions.


DECEMBER 2014 / JANUARY 2015 //



Onduvilla fulfilled the requirements brilliantly. Non-corrosive and well-suited to coastal areas, the tiles could be curved to fit any roof shape, so they could be applied to an existing roof structure with little or no alteration. Minimal maintenance was required once fitted, and clients had a choice of attractive roofing colours.

It has taken a fair amount of trial and error to develop an appropriate technique to convert thatch to Onduvilla® roofs. When laying roof tiles on a conventional roof with straight planes and angles, the wooden frame which holds the tiles has branderings/battens set at specified distances, according to the tile being used. Tiles are applied to this flat surface. Curved surfaces change the regularity in the setting of the tiles, breaking the regular lines, spacing and coverage of the tiles and leaving them somewhat out of sync and oddly spaced. Attempting to apply rigid roofing tiles or sheeting to a structure with such irregularities, whilst still maintaining the original curves and contours, poses significant challenges and could result in a finish where tiles will not sit uniformly against each other. The roof could look uneven with dips and eddies in the tiles, and result in leaks – particularly in tricky corners and drainage valleys. This seems to imply that converting a thatched roof to an alternative roofing solution would mean the entire roof structure might need to be stripped and replaced with a regular, symmetrical sub-structure, before the new roofing product can be fixed to the roof. But this is not so.


Bosazza’s experience in a wide range of roofing projects including thatching and more conventional types, as well as his hands-on approach and passion for roofing excellence, have enabled him and his team at Cintsa Thatching to devise an effective system to the appropriate specifications to support Onduvilla® tiles. The result retains the shapely look of the original roof method and utilises the original structure. Cintsa’s highly trained team of thatchers and roofers, and their refusal to cut costs or take shortcuts allow the company to offer guarantees on their workmanship. All structural work is overseen by a qualified engineer and they proudly claim that theirs is the highest quality thatching and finishing available.

In oversheeting thatch, Onduvilla® can be fitted over the entire original roof or parts of it. A lightweight substructure is added without having to strip the entire roof and, depending on the colour used, the tile looks remarkably similar to actual thatch. A major advantage is that matching Onduvilla® valley and gutter accessories can easily be incorporated when used over thatch to provide drainage. Such specialised fixings and matching accessories comprise an important part of the Onduvilla® complete roofing system and the company will gladly give training in their use, making installation of Onduline® products a cinch. Since they are asbestos-free and have no sharp edges, Onduline® products are a quick, safe and easy-to-install option for even the ordinary ‘bloke in a shed.’ To ensure there is no margin for error, Onduline® provides a complete fixing guide, instruction manual and instructional video, as well as catalogue and leaflets.

As if the ease of installation and positive aesthetic, acoustic and insulation properties of Onduvilla® weren’t enough to convince buyers, the product is also pallet-sized and fits comfortably into an average-sized car boot. Its light weight means more tiles can be transported per load, whilst the flexibility of the product also negates breakage headaches associated with long haul transport over uneven African road surfaces. These attributes make Onduvilla® a surprisingly cost-effective roofing solution overall.

Cabin fever

Rustic Homes, based in the heart of the Western Cape timberland, is an ethical company that now offers a simple solution to compact luxury housing through modular design and prefabricated components with their new prototype: the Rustic Eco Cabin.


vailable on order in the Western Cape from November and nationally in 2015, the small cabin is pre-made in the Rustic Homes factory in Elgin, is simple to set up on site and can be installed completely off the grid as it has been designed to operate off solar power and gas. These environmentally friendly solutions, along with the Rain Queen tank that stores 1 000 litres of water for water supply, are optional extras. “We have long been looking to provide a cost-effective and conscious solution to the holiday home market without compromising on quality,” says Pieter Silberbauer, Managing Director of Rustic Homes. “With the Rustic Eco Cabin, we think we have found an excellent solution. It is a very small house at 32m2, excluding the deck and outhouse, with a minimal carbon footprint. There is no wasted space within the building and a reduced amount of material is used in the construction through clever design for compact living. It is the antithesis of the big luxury beach house that comes with high rates and big electrical bills.”


DECEMBER 2014 / JANUARY 2015 //

“The living area serves as the heart of the home as well as the centre of the structure. The kitchen unit at the back is open plan and bedrooms on either side of the main living area offer bracing to the main structure. The front deck forms the fourth quadrant neatly balancing this symmetrical unit,” explains Pieter. “Like buying a motor car there are different levels of finishes that you can choose. The kitchen and bedroom fittings are designed to neatly fit in with the compact structure of the homes. One could use the sub floor of OSB board which can be finished as a cost-effective option, or like choosing leather seats for an A-class Mercedes, one could have oak floors instead.” The internal linings of the cabin are a beautiful spruce. The house is well insulated and predominantly clad externally with aluminium. Windows are epoxy coated aluminium for longevity and easy maintenance and the roof is zinc aluminium with the option of aluminium for beach-front properties on the extremely corrosive West Coast. Jarrah trim gives a good wooden style finish to the exterior cladding without sacrificing the low maintenance.


All the structural elements of the building are Radiata Pine grown in Grabouw’s managed plantations. It is an important element in the eco design, as this wood is locally produced and also has the benefit of having the highest density and strength of Radiata Pine grown anywhere in the world. Rustic Homes makes a point of using local timber wherever possible in all of their structures.

The outhouse is literally an outhouse, which if cleverly placed could also be known as a loo with a view. It is Swiss log cabin in the mountain meets cost effective simplicity. The Rustic Homes stamp of class and quality is unmistakable. “This is the perfect solution for people wanting a weekend cabin on a farm away from services. It also lends itself to resorts looking to set up in remote locations, as the installation is a fairly simple affair with little impact on the surrounding vegetation,” concludes Pieter. The prototype has been set up at the Rustic Homes factory in Elgin as a show house and is available for rent as a selfcatering unit that sleeps four comfortably.

'The Wish List What I Have Always Wanted Is...' exhibition at London Design Festival 2014 Project demonstrates the versatility of American hardwoods and the ability to experiment with designs both big and small 72

DECEMBER 2014 / JANUARY 2015 //


‘The Wish List – What I Have Always Wanted Is….’ exhibition, a unique collaborative project between some of the world’s best-known design names and upand-coming designers, opened on September 15, 2014 at the Victoria and Albert Museum as part of the London Design Festival 2014, which ran until September 21, 2014. Commissioned by the American Hardwood Export Council (AHEC), the leading international trade association for the American hardwood industry, and brought to life by Benchmark Furniture, the compelling installation had an extended stay at the V&A until October 24, 2014. The project demonstrates the versatility of American hardwoods and the ability to experiment with designs both big and small. Terence Conran, co-founder of Benchmark, instigated the project when he wrote to his friends and asked, “What have you always wanted in your home, but have never been able to find?” Such an open brief guarantees an extraordinary spread of design and the challenge was to produce each project in a single material: American hardwood. Conran’s friends are, of course, some of the most renowned names in architecture and design. Paul Smith, Norman Foster, Amanda Levete, John Pawson, Alison Brooks, Zaha Hadid, Alex de Rijke, Allen Jones and Richard and Ab Rogers have all proposed a longed-for product. “The Wish List has not only engaged the interest of these ten design legends, each of whom commissioned something for their personal collection. It has also given an extraordinary opportunity to a talented group of emerging designers, who worked closely with their commissioners to develop the designs and constructed them with the help of Benchmark’s master craftsmen, some with 40 years’ experience to draw on. The result is ten beautiful objects in a variety of American hardwoods, including red oak, white oak, walnut, hard maple, ash, tulipwood and cherry. The pieces show the amazing versatility that can be achieved with a single material,” said Roderick Wiles, AHEC Director for Africa, Middle East, South Asia and Oceania. Terence Conran himself commissioned a workspace in red oak and cherry from Sebastian Cox, who crafted a complex and ingenious cocooned desk with shelving units; Norie Matsumoto created the perfect set of tulipwood pencil sharpeners for Norman Foster; Win Assakul designed and made an extendable 3m long walnut serving dish for Amanda Levete. Gwendolyn and Guillane Kerschbaumer, the sisters who form Studio Areti, designed a suite of interior architectural elements for John Pawson: a set of walnut shelves, a tapered white oak door, a set of walnut hooks and pegs and a walnut light switch, all for his new house.

// DECEMBER 2014 / JANUARY 2015



"The diversity of the pieces in The Wish List - and making them in one intense week - tested all involved. We had great successes, a few tears, some tantrums, but I think everybody learned a lot about craftsmanship and making. This project is a terrific platform for learning, enriched by the interaction of so much design and making talent." Felix de Pass designed simple but strikingly elegant cherry kitchen stools for architect Alison Brooks; Gareth Neal made two extraordinary sculptural vessels out of white oak for Zaha Hadid; Nathalie de Leval, who is also a cabinetmaker, designed and built a personalised garden shed for Paul Smith out of thermally modified ash; Rob Barnby and Lewis Day of Barnby & Day created a dramatic circular dining table for Alex de Rijke using engineered cross laminated tulipwood. Richard Rogers, together with his son Ab Rogers, requested a red oak ladder that they could sit and work on from Xenia Moseley; and Lola Lely interpreted a very unusual design concept for a reclining seat from artist Allen Jones constructed out of maple and walnut veneer.

scientific tool that helps manufacturers establish environmental frameworks that assess true sustainability. The results present the cradle-to-grave impact of each product across six categories. The most topical impact category is global warming potential (GWP), or carbon footprint.

“Benchmark is the powerhouse of craft, where many of the world’s greatest designers come to push the boundaries of what is possible to do in wood,” said Sean Sutcliffe, cofounder of Benchmark. “The diversity of the pieces in The Wish List – and making them in one intense week – tested all involved. We had great successes, a few tears, some tantrums, but I think everybody learned a lot about craftsmanship and making. This project is a terrific platform for learning, enriched by the interaction of so much design and making talent.”

All of the objects on display at the V&A were built during the first week of July when some of the country’s finest young design talents descended on Kintbury, in Berkshire, where Benchmark’s 50 craftsmen helped bring to life their designs for The Wish List. A consignment of American white oak, walnut, tulipwood and cherry was kindly donated by timber and panel products distributor James Latham for this project. In addition, Morgan Timber donated thermally modified American ash for Paul Smith’s shed. AHEC has developed a microsite for ‘The Wish List’ project, which is now live at This will be the hub for all information regarding the project and currently includes complete details regarding the design teams and project descriptions as well as images.

During the manufacturing process, the teams recorded all energy consumption and assessed the environmental impact of each object using data from AHEC’s Life-cycle environmental assessment (LCA) research. LCA is a

“Working with AHEC on ‘Out of the Woods’ in 2012, Benchmark produced the world’s first wooden furniture with full LCAs,” added Sutcliffe. “Now we seek to build on that learning and develop tools that will enable designs to be rationalised on the basis of LCA data feedback. It is an exciting moment to be working within this fast-developing science.”

GETTING AWAY FROM IT ALL COMMISSIONED BY TERENCE CONRAN DESIGNED WITH SEBASTIAN COX MADE FROM AMERICAN RED OAK AND AMERICAN CHERRY Sir Terence Conran asked designer Sebastian Cox to create a “cocoon-like desk” in red oak and cherry for his office – a place where he could work without distractions, with everything he needed at hand. “I like the idea of being cocooned away, happily designing or writing in blissful peace,” he says. “And it will save me going into the greenhouse in my garden, which is currently my favourite place for quiet time.” Why doesn’t the design titan simply do it himself? “While I’ve had the occasional piece customized,” says Conran, “I have never once had the opportunity to design something purely and selfishly for myself.”

Regarding Conran’s brief for a desk, Sebastian says, “It’s a space Terence can work in without distractions, a cocoonlike desk with cabinetry around it, a space for undistracted creative thought.” Yet building it from red oak, cherry and ash took more than a little creative thought, and considerable skill. The 2mm red oak strips Cox chose for the curved screens had to be soaked in a brook on the Benchmark property before they could become supple enough for weaving. Then Cox finished them with a whitener to lighten their appearance to Conran’s specifications. For the cupboard roll-top, Cox joined solid pieces of wood mechanically, then built a drawer to conceal the mechanism. “This was the most advanced, intricate and challenging thing I had ever made,” says Cox, “but how often do you get the chance to design something for someone who is so important in the industry?” For his part, Conran says, “I have been making furniture for 60 years, but I am still learning from Sebastian.”

CASE STUDY A STOOL FOR THE KITCHEN COMMISSIONED BY ALISON BROOKS DESIGNED WITH FELIX DE PASS MADE FROM AMERICAN CHERRY Alison Brooks wanted an object that she would not only own but also put into production. She commissioned a stool for her kitchen from Felix de Pass that could work in a range of environments. “The stool,” she says, “is always the most popular seat in the house. Stools offer a dynamic kind of seating. There's a temporary quality to sitting on a stool – you don’t have to commit to sitting down. I’ve never been able to find a really clever, beautiful kitchen stool that is the right height for a kitchen counter.” She chose cherry wood, a timber she felt was under-appreciated and which her mother collected when she was growing up in Canada. “Cherry has a tight grain with lots of character. The color grows darker and richer over time to an incredible burnt umber colour,” she adds. The stool consists of a cherry seat and post that de Pass steam-bent into three legs. With Benchmark’s help, he laboured over how to attach the stainless-steel footrest, or 'crown', settling, eventually, on three discreet metal bars. Brooks helped the designer refine the seat into a light disc that becomes sturdier where it joins the base.

TULIPIFERA SHARPENERS COMMISSIONED BY NORMAN FOSTER DESIGNED WITH NORIE MATSUMOTO MADE FROM AMERICAN TULIPWOOD Norman Foster may run one of the most technologically advanced practices in the world, but he still likes to draw. “For as long as I can remember the pencil and I have been inseparable companions – sketching and scribbling are integral to my way of life.” He described his wish as “a pencil sharpener for three sizes, capable of sitting on a desk and with a compartment to receive the shavings.” Foster has more than one desk, so the wish expanded into a family of pencil sharpeners, each for a different location. Foster and Matsumoto chose to design the pencil sharpeners in American tulipwood, which is often seen as a low-quality timber, abundant and inexpensive. But Foster loved the variation in colour. “Of all the samples we examined,” he says, “it was uniquely pale and the grain had an almost marble-like quality.” The cube, cylinder and sphere were cut from solid pieces of tulipwood, but the tetrahedron, at four inches, was wider than the thickest available stock. To compensate, Matsumoto cut triangular pieces from the wood and joined them together. “The angles and jointing were challenging. There were a lot of practical issues I had to solve,” she says. Each sharpener has a tray to sit on that is large enough to hold a sizeable collection of pencils.


DECEMBER 2014 / JANUARY 2015 //


VES-EL COMMISSIONED BY ZAHA HADID DESIGNED WITH GARETH NEAL MADE FROM AMERICAN WHITE OAK Zaha Hadid’s wish was very open-ended, simply specifying ‘tableware’. Gareth Neal approached the project by thinking about the fluid nature of Hadid’s work but juxtaposing that with a functional element dynamic. From this, the water carafe idea emerged. He was invited to go to Hadid’s office and work with her design team, using the company’s modeling software to create the vessel; there he conceived the idea of extruding the form along one of its axes with a slit opening at the end that allowed the viewer to look into ‘a cathedral-like space.’ Benchmark had to upgrade its CNC software to achieve the complicated form. Neal constructed the vessels in two halves, which were expected to be identical, but in fact were not quite, adding the sense of a ‘maker’s mark.’ The process produced ridges that were analogous to those created by a potter’s thumb. Neal and Hadid agreed to keep one vessel natural, while the other was ebonized. Sean Sutcliffe says of the results, “I have been running my workshop for 32 years, and this is the most remarkable thing we have ever made.” Gareth Neal adds, “I hope the pieces will embed the design with a sense of the handmade through the arm of a robot, questioning the viewer’s perceptions of craft and the handmade.”

THE HOLE CHAIR COMMISSIONED BY ALLEN JONES DESIGNED WITH LOLA LELY MADE FROM AMERICAN MAPLE AND WALNUT VENEER Jones’ wish was for a recliner in the shape of a human form, a concept he developed more than 10 years ago, but, he says, “I didn’t have the facilities to pursue it.” The idea was that it should have a personalized form, fitted to the contours of his own body, while also deliberately androgynous. A dowel inserted into the drainage hole would take its inspiration from the removable phallus on Marino Marini’s statue of a horseman in front of the Peggy Guggenheim museum in Venice. The chair evolved from a recliner into a more upright chaise longue. Lely made a full-sized model at Benchmark, then drove it from the workshop to Jones’s home at London’s Barbican, so he could have it ‘fitted’ in the truck outside, to the entertainment of passers-by. Of The Wish List project, Lola Lely says, “I was the problem solver. It was all right not to be so much of a designer on this project. This is what Allen wanted and what he got.” She constructed the chair from maple and walnut veneer. “The only way we could make the shape I wanted was in veneer,” she says. The main timber, maple, is a uniform pale color, and contrasts well with the dark tones of walnut. Lely built up the form with 13 layers of veneer, adding special top and bottom walnut layers with marquetry. “They went together like jigsaws,” she says.

CASE STUDY 6 X 500 COMMISSIONED BY AMANDA LEVETE DESIGNED WITH WIN ASSAKUL MADE FROM AMERICAN WALNUT Amanda Levete often entertains up to 18 people at the 4.8m-long dining table she designed for her home. She loved the idea of a long and reversible serving dish that would allow people to help themselves to cold meats or fruit. She also asked for a storage box that should be as beautiful as the dish itself. Levete commissioned Win Assakul to design the pieces saying, “He is quite exceptional as a designer, thinker and communicator. It is rare to find those qualities in one so young.” Levete and Assakul chose American walnut to give the dish a rich and luxurious quality. The idea was that the dish would be nearly flat on one side, for cold meats and cheeses, and with deeper hollows on the other side, for fruit. It is in six pieces: four interchangeable central sections, and two ends. Assakul hand-carved each section and used dovetail joints to join the pieces. Creating these was a delicate balancing act – they had to be tight enough to fit, but not so tight that a mallet would be needed to separate them. The contoured reversible walnut dish with brass edging is in six pieces. Every piece is subtly different because of the hand carving. “We had designed it with as little flat surface as possible on the underside, to reveal as much of the grain as we could,” says Assakul.

ROOM COMMISSIONED BY JOHN PAWSON DESIGNED WITH STUDIO ARETI MADE FROM AMERICAN WHITE OAK AND WALNUT John Pawson commissioned a family of elements for the country house he is currently remodeling for his family. The site includes agricultural buildings dating back centuries. “Rather than starting with the idea of commissioning a specific piece of furniture, I was interested in getting Studio Areti to explore the things you touch and use every day, that are moments in the life of a place as well as objects – switching on a light, opening a door, hanging a shirt on a hook, taking a book down from a shelf,” he said. Pawson had not worked with Studio Areti before but says, “I was interested in the breadth of training and experiences the two sisters bring to their design studio – from architecture and art history to product design.” The team chose white oak and walnut. “We’re exploring the possibilities of their colour contrast and very different characters of grain,” says Pawson. The most complex element the pair designed was the door. “When you have a door in a wall it is an interruption to a very pristine surface,” says Gwendolyn. “We decided to design a door that is not ashamed, but that works with the wall in an elegant way.” The solution was to taper it, so it always looks half open - though this made hanging it more challenging. The dimmer switch demonstrates the sisters’ attention to detail. When the light is off, the grain on the knob is aligned with that of the base plate.


DECEMBER 2014 / JANUARY 2015 //


TABLE TURNED COMMISSIONED BY ALEX DE RIJKE DESIGNED WITH BARNBY & DAY MADE FROM AMERICAN TULIPWOOD Alex de Rijke wanted a large circular laminated tulipwood pedestal table that looks as if it has been carved from a single tree. “We know everything takes place at the table,” he says. “The best decisions are made, meals are enjoyed, homework is done, computers are used.” A round table is, he says, “more democratic. It means that children have as much say as adults.” Having designed ‘Endless Stair’ in collaboration with AHEC in 2013, de Rijke wanted to work with tulipwood again because he liked the fact that it is strong, light, abundant and beautiful. “The liveliness of the grain varies because it has grown in different microclimates,” he says. The design was initiated by de Rijke and then developed collaboratively with Barnby & Day. Rob Barnby and Lewis Day built up the table from 13 rings of three-layered cross-laminatedtimber (in CLT, the grain runs in opposing directions on each layer, making the panels stronger and more stable). The table was turned in three sections. “It was incredible to watch such a large object turned on the lathe,” says Day. The largest section turned at a speed of 62mph on the outer edge, so it was essential that nothing went wrong. De Rijke spent a day at Benchmark while the top was turning, refining the profile of the edge. The end result weighs in at 170kg – more than was anticipated, but far less than the weight of the solid table it appears to be.

THE LADDER THAT LIKES THE WALL COMMISSIONED BY RICHARD AND AB ROGERS DESIGNED WITH XENIA MOSELEY MADE FROM AMERICAN RED OAK Richard and Ab Rogers wanted a ladder that would allow them to perch at a height and be comfortable enough for writing, eating and working. They also wanted it to be economical with materials. A ladder, says Ab Rogers, “is a simple diagram of how to get you off the ground.” To be sturdy enough for all those tasks, it needed to invert the A shape of a traditional fruit-picking ladder. Total stability would be borrowed from the existing architecture of the surrounding environment, leaning on a vertical surface – a wall or a bookcase. For The Wish List, Moseley saw herself as a facilitator. “At first I didn’t see my stamp,” she says, “but now it is very much a meeting of minds.” She became involved with the steam-bending of the American red oak she chose for the ladder (red oak was chosen for its receptiveness to steam-bending). The uprights of the ladder had to be designed so they could provide handholds for people going up and sitting down. Moseley, along with the Rogers, resolved this elegantly, designing one upright with a tight outward curve at the top, and another extending beyond the tray, which can fold away. “It has been such a roller coaster and a whirlwind,” says Moseley. “It’s been more productive than I could ever have imagined.”

PAUL'S SHED COMMISSIONED BY PAUL SMITH DESIGNED WITH NATHALIE DE LEVAL MADE FROM THERMALLY MODIFIED AMERICAN ASH Paul Smith’s request was for a garden shed, “Somewhere you can go to switch off, somewhere to relax,” he says. “In today’s world where everyone is so busy, I think this is really important and very needed.” He stipulated that one end of the shed should be glazed, offering a view out. And, like the shed George Bernard Shaw used to write, Smith wanted his to rotate, so he could take advantage of sun or shade at different times of day. Paul Smith chose to work with Nathalie de Leval, saying, “Nathalie’s understanding of the materials she works with is really amazing. She combines this with fantastic craftsmanship to make something truly contemporary.” As Smith wanted the shed to be all wood, thermally modified hardwoods, with grade-one durability, seemed a sensible choice. De Leval chose thermally modified ash for its dimensional stability, rich colour and grain. She consulted with Arup’s timber specialist, Andrew Lawrence, on the structure, which had to be demountable. “Paul’s Shed is the first structural use of thermally modified

American ash,” says Lawrence. “The thermal modification makes the ash resistant to decay and imparts a wonderful dark tone, while at the same time preserving enough strength for modest structural use. The next step will be to do some formal strength testing.” De Leval spent two days making the base, which sits on a hand-rotating mechanism. Diagonal tensioning cables hold the shed in shape. “It is all incredibly low tech, which I like,” says de Leval. “It’s a flat pack. But it was a lot of work. I did seven issues of drawings.”

The new passion --create something with wood Wood Conference celebrates its 5th anniversary on 17 February 2015


ince its inception in 2000 with 60 participants, the Wood Conference has grown to host almost 400 delegates in 2014 and has held CPD accreditation over the last 3 years. Well represented by professionals from various sectors, this large forum brings together local and international speakers, highlighting new and traditional trends using wood. The objectives of the conference are to provide a platform for industry professionals to share information about timber technologies, architecture, standards, and topical issues, to network with a highly targeted delegate base, and also to motivate upcoming architectural and carpentry students on the benefits of working with wood. A large number of carefully selected local and international speakers will present their topics relating to timber in architecture and sustainable construction in line with South African trends and standards. Already secured are two European speakers who will present on timber construction for large buildings (Elephant Park), as well as tourist-driven buildings, like sustainable hotels, for example. The Wood Conference 2015 programme, which comprises a rich line-up of speakers and workshops, aims to share a great deal of information, vision and knowledge. In previous years attendance to the Wood Conference was free of charge and through skilful planning, the fifth

anniversary conference will also be hosted free of charge by HWZ International SA (Pty) Ltd. Furthermore, the organisers are proud to announce that foreign investors are showing keen interest in investing in technical timber to produce wooden houses, and the construction know-how that leads to creating jobs for the local market – activities which were brought about by the impetus of the Wood Conference. In conjunction with the Wood Conference, the Wood Student Foundation (WSF) was founded, with the aim to give young students an opportunity to study timber related subjects, or win an internship in Switzerland, by participating in the WSF competition and submitting the best thesis on wood. The Wood Conference’s founder, George Kuratle and his team look forward to your participation.

Coatings for Africa 2015 In line with the changing face of Africa's growing paint and coatings industries, Coatings for Africa 2015 symposium and expo, taking place 11-13 May 2015 at the Sandton Convention Centre in Johannesburg, sets out to drive innovation and education in the paint and coatings industry across the continent.


he African coatings industry remains key to supporting the continent’s ever-growing development requirements. The future for the paint and coatings sector looks particularly promising, given the strong economic outlook, long-term demographic growth and rising urbanisation across Sub-Saharan Africa.

The Protective Coatings Seminar focuses on challenges around corrosion for users from the industrial and automotive sectors. The programme is completed by a series of free workshops for users of paints and coatings products on the exhibition floor.

Recognising opportunities in South Africa and beyond, Coatings for Africa is creating a completely new experience in 2015. With a distinctly pan-African focus and a minimum of ten African countries represented, the event connects buyers and sellers from across Sub-Saharan Africa as well as globally.

Coatings for Africa is hosted by the Oil & Colour Chemists’ Association (OCCA) and the South African Paint Manufacturers Association (SAPMA) in conjunction with Hypenica and is the biggest showcase of coatings technologies, paint and related products on the continent.

To generate additional synergies, Coatings for Africa is hosted alongside African Construction and Totally Concrete Expos, Africa’s biggest gathering of the concrete and construction industry. Africa’s only three-storey expo is opening even more doors for business development.

Coatings for Africa connects the entire value chain, from raw material suppliers to end users of the finished paint or coatings products. Attendees can expect 120+ exhibitors, 2 000 attendees, 10+ African countries represented and 30+ expert speakers.

A comprehensive conference programme caters for all needs across the value chain. A technical symposium presents the latest innovation and developments the global paint and coatings industry has to offer. The Coatings for Construction Seminar offers a one-stop solution for users of paints and coatings from the construction industry.
