Sustainable construction requires consideration of not only the environmental impacts of construction but also the social and economic impacts as well. Reducing the built environment’s impact on carbon dioxide and other emissions to help tackle climate change and pollution, the efficient use of scarce resources, and improving health and safety represent just some of the challenges facing the construction industry. As a responsible manufacturer, Redland is committed to helping meet these challenges. Drawing upon its heritage, Redland is a name that can be trusted to help meet the contemporary challenges of sustainable construction. Since its foundation in 1919 Redland has dedicated itself to meeting the challenges faced by the construction industry. In 1926 Redland played an integral part in the construction of post-war Britain, supplying concrete roof tiles that were desperately needed in the absence of coal-fired clay tiles that were unavailable due to the general strike. A generation later Redland was instrumental in re-roofing London, with its mass-

produced Redland 49 concrete tile, establishing itself as a staple of the London landscape. With its Queen’s Award-Winning Cambrian Slate launched in the mid1980s – a product ahead of its time in terms of its high recycled waste content – Redland demonstrated that a traditional slate roof appearance could be achieved with a more cost-effective single lapped tile. In 1997 – before the Kyoto international agreement on reducing carbon dioxide emissions was signed – Redland was the first roof tile

manufacturer to launch a roofintegrated photovoltaic solar panel for generating electricity from a renewable source. Redland’s goal is to be the preferred supplier for its customers in terms of meeting their sustainable roofing needs while reducing our environmental and other impacts. To achieve this goal Redland invests significantly every year in our core values of roofing know-how, industrial excellence and customer focus.

Cambrian Slate

As well as working with the Environment Agency to help protect and improve the environment, Redland operates an environmental policy and management system across all its sites in the UK and Ireland, covering energy efficiency, waste minimisation, water efficiency and pollution reduction. Our continuous improvement process ensures that the embodied environmental impacts of Redland products are minimised.

• Raw materials – Our concrete, clay and Cambrian products are manufactured from raw materials that are over 80% (by volume) sourced from suppliers operating to the ISO 14001 environmental management standard. Redland is working with its supply chain to increase these percentages. • Energy efficiency – Every year we benchmark all our UK plants against over 200 Monier Group roofing plants around the world, to help improve energy efficiencies and learn from sharing best practice. Our UK plants currently rank among the best in the world as we constantly strive to further minimise our impact on the environment. • Recycling waste material at our plants – The recycling of broken concrete and clay tiles and waste mortar for use in our tile production continues to increase, thus minimising the amount of waste solids having to be removed from site. Polymer coatings are recycled at all concrete plants where used. Cambrian Slate itself includes a minimum of 60% recycled Welsh slate taken from slate waste piles.

Furthermore, our Cambrian plant has reduced its reject rate, with only 1% of total raw materials going to landfill. • Waste water recycling and treatment – Surplus water used during production is recycled and used in the manufacturing of other products. We have also installed water treatment plants and/or settlement lagoons at plants to ensure that any water runoff is correctly treated before it enters into the water courses. • Packaging – We annually review our packaging and the energy used to wrap our products. Supplier packaging is recycled wherever possible.We have also introduced a pallet returns system where our customers are encouraged to return the wooden pallets on which our products were packaged. These pallets are then reused for future product packaging. We currently reuse 100,000 pallets per year.

• Logistics – Our 8 plants and 4 depots are strategically positioned throughout the UK to reduce the amount of transportation of products around the country, thereby reducing congestion and pollution. Our haulier sees the use of biofuel as a major step forward in reducing their carbon footprint and currently have 750 of their 8000 vehicles running on a 50:50 standard diesel to biofuels mix. • Recycling used product at the end of its life – All our concrete tiles can be recycled for use as aggregate in building applications such as roads and paths, and all our plastic components are also fully recyclable. Clay tiles can be reused.

SUSTAINABILITY ROOFING MATERIALS Fossil fuel energy use, and the carbon dioxide emissions produced as a result, is thought to be the single largest threat to our planet. In the UK about 50% of all energy use results from the construction and operation of buildings. Although the embodied energy of building products is less significant than the energy used to operate buildings, the focus on reducing the impact of building products is likely to increase. The manufacture of building products generates various environmental impacts in terms of energy, waste, water use and pollution. Although the sustainability of building products is difficult to quantify, the Building Research Establishment Environmental Assessment Method (BREEAM) has become the standard tool in the UK for quantifying the overall embodied environmental impact of building materials, the building elements (roofs, walls, floors, windows, etc) they make up, and buildings as a whole. The BRE produce a guide using BREEAM called the Green Guide to Specification, which summarises the full life cycle impact of building elements (roofs, walls, floors, etc), depending on the materials used as part of standard construction details.The current Green Guide grades these elements on an A+, A, B, C, D, E scale where A+ represents the lowest environmental impact and E the highest.

• Redland Concrete and Clay Tiles As members of the Concrete Tile Manufacturers Association and Clay Roof Tile Council, data supplied for Redland concrete and clay roof tiles enabled the 2008 BRE Green Guide to Specification to award the highest A+ rating (lowest environmental impact) for generic concrete interlocking and plain tiles in all roof constructions. Clay tiles achieve either an A+ or A rating depending on roof construction. • Redland Cambrian Slates are the most eco-friendly resin slates available.The 2008 Green Guide to Specification awards generic resin slates an A rating when part of standard roof constructions.



• Redland Natural Slate – Redland supplies only the highest quality natural slates from Spain and Argentina through a partnership agreement with slate specialists SSQ Group. Generic natural slate from the UK achieves an A rating in the 2008 BRE Green Guide to Specification for standard roof constructions. • Redland Metal Roofing – Redland’s metal roofing range of coated steel profiled sheet products is manufactured within strict environmental targets. The 2008 Green Guide to Specification awards generic coated steel profiled sheet products an A rating for common constructions such as double skin construction. Steel can also be recycled an unlimited number of times without losing its quality.

RENEWABLE ENERGY For a typical building only 10% of the energy it has consumed over its lifetime is a result of its construction. Approximately 90% of energy consumption results from the provision of heat and power.To reduce energy consumption and carbon dioxide emissions therefore requires buildings that are energy efficient in use. However, to operate a building without producing carbon dioxide emissions requires renewable, zero carbon sources of energy to provide both heat and power. Harnessing solar energy is one of the most attractive means of generating zero carbon, renewable energy for use in buildings, and the roof is the ideal surface for solar energy collection.

ST 4 Solar Water Heating System

The solar water heating roof panel system from Redland has been specifically designed by the Redland roofing experts for integration into pitched roofs.The solar water heating system generates domestic hot water and when connected to the household hot water system, can significantly reduce consumption of natural gas or other fossil fuels.The system is supplied with a standard hydraulic control kit containing controls, valves, pump, sensors and expansion vessel, as well as a fixing system that allows seamless, guaranteed secure and weathertight integration into the roof surface. The Redland solar water heating system can also be used for space heating or swimming pools.




Redland leads the way in the development of mechanical or ‘dry-fix’ roofing systems to provide neat, maintenance-free and cost effective roofing solutions that will stay put no matter what the weather brings.

Good roof design does not just mean choosing the right tile or slate. The protection of the supporting structure from the harmful effects of condensation is equally important.The proven method for preventing condensation is through the use of effective roof ventilation.

Our dry-fix systems eliminate the need for mortar bedding ridge, hips and verges, and have a number of advantages: • Fully tested against the elements to secure the roof in severe weather conditions • Eliminate problems of mortar failure due to poor workmanship • Maintenance-free • Quick and easy to fix with no special tools required • Can be laid even when bad weather is expected • Incorporate ventilation at the ridge • Compatible with most tiles and slates • Comply with BS 5534 requirements for mechanical fixing, and BS 5250 for ventilation Like all of our products, the durability of our dry-fix systems has been extensively tested under all climatic conditions, from the UV rays of the blazing sun to sub-zero temperatures. They are also laid on roofs in our purpose built wind tunnel to assess their performance against the UK and Ireland’s most severe storm conditions.This thorough approach has enabled us to achieve Agrément Certification for the majority of our dry fixed systems. Based upon our industry leading know-how we are able to guarantee that a complete Redland roof covering will remain secure and weathertight for 15 years.

Condensation in roof spaces has become an increasing problem for several reasons. Part L of the building regulations is driving up standards for the airtightness of dwellings at the same time as encouraging use of increased levels of insulation. These changes in building standards – to reduce energy consumption – coupled with householders’ increasing use of appliances such as dishwashers and tumble dryers, have contributed to the increasing presence of water vapour in colder roof spaces. BS 5250, Code of practice for control of condensation in buildings, sets out best practice recommendations for managing condensation risk in roofs and complying with Part C of the building regulations. Specification of the most appropriate form of roof ventilation depends largely on how airtight the ceiling is. Broadly speaking, ventilation solutions can be divided into those designed for roof constructions with a well-sealed ceiling (Breathing Roof Solutions) and those where the ceiling airtightness is not as good (Traditional Ventilation Solutions). Well-sealed ceilings With traditional construction methods it is not possible to guarantee a completely sealed ceiling. It is also not possible to guarantee that the ceiling will remain sealed for the design life of the building.

With care over design and good workmanship, however, it is possible to achieve a well-sealed ceiling such that less ventilation is needed than provided by traditional ventilation solutions. BS 9250:2007, Code of practice for design of the airtightness of ceilings in pitched roofs, describes both the detailed requirements and robust details for achieving a well-sealed ceiling. Requirements include the presence of well-sealed pipe and cable penetrations including light fittings, in addition to a well-sealed loft hatch. Redland’s range of Breathing Roof solutions provide the optimum specification when a well-sealed ceiling is installed.

Storm damage can be prevented by using our dry-fix systems.

Breathing Roof Solutions The diagrams below show a summary of the products we provide to satisfy the requirements of BS 5250 5mm

Insulation at Ceiling Joist Level – Well Sealed Ceiling • Standard duo-pitch roof with Spirtech 250 underlay • Underlay Support Tray at eaves


REDLAND BREATHING ROOF SOLUTIONS Redland’s range of Breathing Roof solutions provides specifiers with simple, robust and guaranteed BS 5250-compliant specifications, designed to meet changes in building standards. When used in conjunction with a well-sealed ceiling Redland Breathing Roof solutions combine all the benefits of a vapour permeable underlay with the reliability and security of a dry-fix ventilated ridge system to control condensation risk, even under severe conditions such as when newly built dwellings are drying out. Redland Breathing Roof solutions use Spirtech 250 vapour permeable underlay laid short at the ridge, in combination with Dry or Rapid Vented Ridge to provide a secure, weathertight system against both storm damage and roof condensation. A fundamental requirement of Breathing Roof solutions is the achievement of a well-sealed ceiling. Failure to achieve this level of ceiling airtightness significantly increases the risk of roof condensation.

Performance Redland is able to provide a complete 15 Year Roof System Guarantee for its Breathing Roof solutions and, when part of a SpecMaster project (see page 15), a full 15 Year SpecMaster Guarantee covering design liability as well. Benefits • Suitable for most roof designs • Guaranteed weathertightness • Dry-fix technology ensures guaranteed, securely fixed ridge tiles • Improved energy-efficiency resulting from reduced heat loss through the roof • Single point of manufacturer responsibility, from the underlay to the tile • No eaves ventilation product required, simplifying eaves details • High-level ventilation ensures water vapour loads are managed effectively
