Understanding acoustics with Timloc

Part E of the Building Regulations refers to the need 'to provide reasonable resistance to sound'. Building products specialist Timloc is aware that the subject of acoustics can often create confusion, leading specifiers, builders and contractors into thinking they need products which are overly expensive or don't actually meet their needs.

industry need to officially clarify the impact of the access panel’s performance to Part E. Timloc’s practical and honest approach to product design and development led it to commission Leeds University to undertake extensive acoustic product testing on its behalf.

The testing was carried out in order to form a performance objective for the development of a new Timloc access panel range that could perform as a direct replacement for plasterboard layers with no negative impact on the acoustic performance of the area, therefore meeting the requirements of Part E. However, tests concluded that Timloc’s existing range of CR slim line access panels has no effect on the overall acoustic rating to walls or ceilings, when fitted as a direct replacement to

plasterboard layers and if fitted within 1% of the total area. As an added advantage, the installed access panel remains slim to offer maximum space in the allotted void.

This presents major benefits to the industry, because the need for high-level dB rated and often expensive access panels can now be limited to specialised applications.

New gas safety legislation due to take force in January 2013, is leading the way to the requirement of many access panels or inspection hatches to be fitted in new and existing homes. In order that the correct access panels are chosen for their surroundings, Timloc has further simplified the specification process by offering a service for the calculation of the weighted value of an application. All they require is the overall area of the wall or ceiling and its specific material (i.e single or double layer plasterboard), the designed dB rating of the wall or ceiling and the area of the access required.

The Timloc access panel range offers practical acoustic (dB) ratings and each product now carries a weighted sound reduction value (Rw). The core CR range has slim profile designs, is fire rated, insulated, air-tightness tested and acoustic performance rated, meeting all the required criteria for most applications.

Timloc has been supplying high performance building products since 1977 and this continued investment in product research and service provision, further supports its on-going commitment to the building industry.

All manufacturing is carried out under the BS EN ISO 9001:2008 Quality Management System.

As well as providing advice and support for the technical aspects of a balustrade project, Sapphire is committed to developing innovative solutions that deliver the optimum mix of style and best value

Creating real value is a science Designing balustrades for social housing projects is the science of integrating durability and safety with budget and beauty. It is easy to compromise safety and visual appeal to gain a low initial cost but combining safety, compliance, and low maintenance durability is the skill in achieving lower lifetime costs. Nick Haughton, Marketing Manager at Sapphire Balustrades considers the challenges in two award-winning developments.

A

lthough aesthetics are obviously important, all balustrades, whether they are for residential or commercial applications, must be fit for purpose. So let’s start by looking at some of the technical considerations.

Firstly, balustrade designs must comply with relevant British Standards relating to structural performance in various design applications, and Building Regulations such as Document M, to ensure they meet the needs of all users irrespective of age or physical ability.

Failing to comply with these requirements can have serious consequences. Apart from a potentially costly project delay if a design is refused by planners or building control, inappropriately designed or installed balustrades can result in fatalities or

permanent injuries and unfortunately many balcony incidents have occurred this year alone.

Balustrades provide a vital protective barrier where there is a change in level greater than 600mm in dwellings.

Balustrades for communal stairways or balconies should be designed to minimise the risk of persons slipping through gaps. In effect, this means that balustrades should not have gaps which permit a sphere of 100mm diameter to pass through, including the ‘triangle’ formed by the tread and riser. It is also important when designing balustrades to ensure that they are not easy to climb, particularly by children.

To make it easier to create compliant designs, Sapphire has developed CABS (Computer Aided Balustrade Specifier), a

free online tool which guides users with recommendations for example compliant handrail diameter and glass infill thickness, and SES (Structural Evaluation System) for producing bespoke structural calculations for individual balustrades or handrail projects. SES provides the necessary data to determine whether a proposed design complies with structural requirements.

As well as providing architects and specifiers with advice and support for the technical aspects of a balustrade project, Sapphire is committed to developing innovative solutions that deliver the optimum mix of style and best value. This can be seen in the use of Sapphire’s new Aluma system for balcony balustrades at an award-winning development of social and private housing in the West Midlands. Many of the balconies for canal-side apartments at Walsall Waterfront South incorporate Sapphire’s new Aluma semi-frameless aluminium and glass balustrades.

Strength and style With this innovative design option, glass infill panels simply slot into Aluma baluster uprights and/or handrail profiles, removing the clutter of traditional patch lugs and leaving a sleek, crisp appearance. Whilst vertical bar balustrades were used on houses and two smaller blocks of apartments, Sapphire’s Aluma system was used

widely for balconies to apartments in phases 1 and 3. Additionally, phase 2 included curved balconies and balustrades to facades facing the canal to bring movement into the building design.

Sapphire created real value by offering a cost-effective solution, and not just for the initial purchase but with a product that combines the aesthetic styling of a structural glass balustrade with the long lasting, low maintenance benefits of high grade aluminium, thereby eliminating the corrosion issues associated with mild steel galvanized balustrades.

Developer Jessup worked with

Staffordshire-based architect S P Faizey and Sapphire to produce balustrades for full-balconies, roof top terraces and Juliet balconies to complement the development’s mix of one- and twobedroom apartments. The applications ranged from individual bolt on balconies to long runs divided with privacy screens. The project’s architect feels that Sapphire’s new semi-frameless Aluma replicates the look of a much more expensive system. He comments: “With no obvious glass fixings, Sapphire’s Aluma balustrades really enhance the look of Walsall Waterfront South and give residents clear views over the

water. In fact, Sapphire has proved such a success here that we’ve already specified their balustrades for other projects.”

Sapphire’s Aluma balustrades have been used for over 250 balconies on four of the residential buildings at Walsall Waterfront South. The project involved a variety of balcony types and

Value engineering As well as providing useful outdoor space for residents, particularly in apartments with no private gardens, well designed balconies can enhance the facade and give the building a unique signature. SP Faizey’s Principal Architect, comments: “We believe in value engineering every project and are always looking for best value solutions that enable us to achieve the desired look and

performance within budget, like Sapphire’s new Aluma system.”

In addition to capital cost, it’s important to consider lifetime costs and maintenance when specifying balustrades, he says: “Designing balcony balustrades with glass panels creates a lighter effect inside and out, and the glass just needs cleaning, while painted metal uprights will require re-painting at some point.”

In a social housing project at Richard’s Close in Harrow, Sapphire has provided safe and stylish internal and external balustrades to enhance retirement living for elderly residents. Balcony terraces and stairways in two new blocks of purpose-designed apartments feature several different balustrade solutions from Sapphire’s aluminium and stainless steel systems. Sapphire’s flexible design and manufacturing expertise ensured that custom features could be incorporated to create a ‘bespoke’ package for the multi-million pound project, from Iroko hardwood handrails to colour laminated glass infill panels, to complement the apartments’ vibrant facades.

Constructed by Mansell for Octavia and Harrow Churches Housing Association, Richards Close offers an affordable alternative to residential care for older people with the reassurance of 24-hour staffing and communal facilities.

Of the 76 apartments, 47 offer extra care facilities, seven have wheelchair access and the remaining 22 provide shared ownership accommodation. Mansell’s Regional Director comments: “Sapphire was able to provide high quality, best value balustrade solutions by combining elements from different standard ranges to satisfy both the practical and aesthetic specification of Richards Close which was named ‘Best New Place to Live’ in the London Planning Awards.”

Tailored solutions

Balustrades provide a vital protective barrier where there is a change in level greater than 600mm in dwellings

Sapphire’s Aluma aluminium system was chosen in a low maintenance bluegrey polyester powder coated finish for upper storey balconies and ground floor terraces in both apartment buildings.

Aluma balusters are combined with either aluminium or hand-finished hardwood handrails and, where used, infill panels of 10mm clear, coloured or pre-etched satin glass to suit individual building elevations. All balcony balustrades and fixings are designed to

meet the regulatory design load for this application of 0.74kN/m.

In addition, Sapphire supplied balustrades to all internal stairways at Richards Close using a variety of systems from its collection. The main staircase features Sapphire’s Onyx satin polished stainless steel system.

Balustrades for escape stairs in each building are manufactured using the Opal polyester powder coated steel balusters and handrails. All staircase balustrades have clear toughened glass infill panels to create a light, open feel to the stairways, and handrails are specially designed to be ergonomically suitable for disabled users in accordance with Building Regulations Document M/BS 5395:2010.

Summing up, Nick Haughton says that achieving the right handrail, balcony or balustrade solution can be a complex process. Finding an experienced company that can provide reliable service and support throughout the design and specification process is critical to minimising time and hassle on site. And in social housing situations the ultimate need is a supplier that offers the best value balance between capital costs, installation costs, and lifetime costs.

sizes, including some with curved glass balustrades, a requirement which posed little problem for Sapphire’s glass design expertise. The aluminium balusters are finished in grey powder coating to match other elements of the facades.

Sapphire manufactured and installed the balustrades as part of a complete project package – Juliette balconies are fixed to the buildings’ steel framework while full balconies are top fixed to the steel frame of each balcony.

Walsall Waterfront South received a Southern Staffordshire Design Award and was successful in two categories in the National Waterways Renaissance Awards. Architect, S P Faizey, says balconies are becoming an increasingly popular feature for private and social housing developments and are even promoted by some planners.

Minimising refurbishment disruption

Refurbishments in social housing can prove demanding due to the disruption of access for tenants. As such, contractors can be faced with tight timescales and deadlines that require a job to be completed as quickly as possible. Specifying the most appropriate subfloor preparation products is key to the installation, as Steven Boulton, Technical Service Manager for F. Ball and Co, explains.

application and speed, to ensure a project is completed efficiently and without delay.

The refurbishment of the kitchen flooring throughout the social housing scheme needed to be completed as quickly as possible to avoid the disruption of access for residents. Contactors began the project by removing the old floorcoverings and remaining adhesive residue before priming the subfloor with a general-purpose neoprene primer, which was used to promote adhesion of the smoothing underlayment to the subfloor.

F. Ball’s Stopgap Fast-Track 30 smoothing underlayment was then installed in the different kitchens to create level, safe and hardwearing subfloor

surfaces for the residents. With a practical working time of 10 to 15 minutes, the product has an early walk on time of just 30 minutes and allows textile and resilient floorcoverings to be installed over absorbent subfloors after only 45 minutes. Furthermore, its rapid drying and rapid setting characteristics are provided through the use of new cement binder technology. This product is also ideal for clinical or sensitive environments thanks to its protein-free formula, which helps to reduce bacteria and mould growth in kitchens and bathroom settings.

Durable bond Following the installation of the smoothing underlayment, Styccobond F44 acrylic adhesive was used to adhere the Polysafe floorcoverings to the prepared subfloors. Styccobond F44 adhesive is designed to give a high-bond strength and strong initial tack, allowing for a strong and durable bond between the floorcovering and the subfloor.

John Woolgar of General Furnishing, explains: “Stopgap Fast-Track 30 was the perfect product for the job as it allowed us to be able to finish several kitchens in one day, something we weren’t able to do before. This meant the kitchens were back in use after only a short space of time, which was ideal for the tenants and for us as it allowed us to get to our next job without any delay.”

Integrated communal heating Tenants on the Hickman estate in Wolverhampton are benefiting from a ÂŁ12m investment as part of the Wolverhampton Homes Decent Homes programme. The two high-rise blocks on the estate, Wodensfield Tower and William Bentley Court, are being completely refurbished and now benefit from the installation of an Evinox communal heating system in each block, which is more energy efficient than individual boilers.

Evinox engineers designed the system from sizing the heating and hot water outputs required for each apartment, the pipework system and routing, pumps and flow rates required to circulate the primary energy and the power required in the plant room to drive the system. This reduced cost and ensured that the correct heating systems was specified for each block.

Enhanced efficiency

communal heating system supplies heat to a number of dwellings from a common heat source or Energy Centre. The Evinox communal heating systems at Wodensfield Tower and William Bentley Court include ModuSat heat interface units in each dwelling, which are powered by central boiler plant equipment located in plant rooms sited adjacent to the high rise blocks. The ModuSats convert the heat generated by the Energy Centre into independent, fast recovery hot water and high efficiency heating for each residence.

This removes the requirement for individual boilers and a gas supply in each home.

This type of heating system provides end users with the same autonomy as if they had their own boiler and tank and just as with their own independent heat source they pay for only the energy they use. There is no requirement for a flue, gas supply or additional room ventilation in each dwelling, making installation simpler,

with easy access for servicing and minimal maintenance requirements.

Wolverhampton Homes’ specification of Evinox for this project proved invaluable in terms of the M&E support and design input provided.

Another key consideration was the ability to source the central plant equipment from the same supplier as part of an integrated package. Two Evinox ADI CD packaged boiler skids were chosen for each building, which due to their compact design and the ease and speed of installation, removed the need and cost of a temporary boiler house.

The pre-packaged skids contain 400kW Evinox ADI CD boilers which provide excellent seasonal efficiency

The Modusat heat interface unit in each apartment includes an integrated energy meter, which accurately records each individual’s energy consumption, and ensures that residents only pay for the proportion of energy that they use.

Wolverhampton Homes decided the Evinox PaySmart metering solution was perfectly suited for its residents at Wodensfield Tower and William Bentley Court. The PaySmart system enables residents to be in control of their own energy bills by paying for the energy as they need it, and therefore removing any burden of building up unpaid bills or debt.

This solution also takes away the collection of money by the housing association.

apartments can be monitored and controlled without the need to visit site for example – properties can be left on frost protection until tenants are assigned, then the heating can be turned on remotely prior to move in; SMS text message control facility enables occupiers to set heating and hot water remotely and view consumption; avoids unnecessary call-outs as a result of simple user error; and provides data logging of apartment temperatures to avoid disputes.

■

By installing communal heating at Wodensfield Tower and William Bentley Court, it removes the requirement for high rise gas infrastructure throughout each building and the associated risks that come with this. There is also no requirement for individual boilers in each apartment, which reduces the risk of carbon monoxide poisoning and the need for annual gas inspections. The removal of the boiler flues also improves the aesthetics of the buildings.

When designing a communal heating system, energy metering, monitoring and billing should be a key consideration from the outset, to ensure the best solution is provided for the residents and the building owner or operator.

Daikin aids Green Deal trial project Daikin Altherma air-to-water heat pumps have been chosen to provide heating and hot water systems for 21 houses in Penwithick, as part of Cornwall Council's Green Deal trial project. Penwithick, a village to the north of St Austell, is off the gas network with varying housing types which are, therefore, categorised as hard-to-treat properties.

A

pproximately 80 properties are participating in the trial with each receiving an average of around £10,000 of energy efficiency and renewable energy measures. The funding for this has been supplied in full

by Cornwall Council’s Green Cornwall Programme.

Ocean Services (SW), of St. Austell, Microgeneration Certification Scheme (MCS) approved suppliers, carried out the installation of the Daikin Altherma Low Temperature Monobloc air-to-water heat pumps, together with new domestic hot water cylinders also supplied by Daikin UK. Phil Smith, Managing Director of Ocean Services, says: “We were very happy to work with the council to provide renewable measures to households at no cost to them.”

Local residents in Penwithick are delighted with their new installations. Mrs Tregenza says: “We are very happy with the heat pump and it provides us with warmth at just the right temperature.”

Mrs Joyce Keevil adds: “It’s early days yet with regard to energy savings, but we are happy with the installation so far.”

Following an initial site survey, the

The outdoor heat pump contains the key hydraulic components, such as circulation pump and expansion vessel to minimise the installation effort and indoor space requirements. This self-contained system is designed to turn energy from the outside air into heat for both space and hot water heating. As the heat pumps consist of a sealed refrigerant

unit, refrigerant handling and associated qualifications are not necessary.

The Daikin Altherma LT Monobloc was chosen as it suits properties where internal space is at a premium. Lower capacity Monobloc models (6kW and 8kW) are particularly suitable for smaller properties and are designed specifically for the UK housing sector, targeting fuel poor, off-gas properties.

Air-to-water heat pumps are fast becoming an excellent alternative to traditional heating and hot water systems in both new build and refurbishment applications. There is likely to be increasing demand, particularly due to the proposed RHI incentives and the Green Deal ECO ‘Affordable Warmth’ targets, which encourage their take-up.

The Microgeneration Certification Scheme (MCS) accreditation provides customer assurance that installations will achieve the highest efficiencies and will meet rigorous and consistent government standards.

MCS certification and an assessment is needed to meet Permitted Development Rights (planning requirements) in England. Since December 2011, air-to-water heat pumps have not required planning permission in certain circumstances and where installed on domestic premises including houses and flats. However, guidance and limitations exist with regard to siting in specific locations, no less than 1m from the property boundary, as well as meet specific noise criteria, and must be installed to MCS standards.
