Designers and specifiers have been exploiting the potential of single ply for over thirty years (e.g. RHWL – Nottingham Royal Centre 1986; Sir Norman Foster – Stansted Airport 1990/2006, Stockley Park 1992). This technology offers a huge range of geometric and performance options. Specify SPRA to get to the most experienced providers in the industry.

 

Quality and performance will not be assured simply by specifying to the harmonised European Standard for single ply membranes, BSEN13956. This standard simply defines common test methods and rules for declaration of product characteristics. SPRA will publish a guide to specification later in 2010. Watch the news section for updates.

Thermal and acoustic insulation is a critical component in modern roof systems. SPRA has developed  ‘Component Quality Schemes’ - a set of minimum standards for entry to SPRA – that will ensure your project performs as intended. They are available for:

• Expanded Polystyrene (EPS) [55.28 KB]

• Mineral Wool (MW) [97.95 KB]

• Polyisocyanurate (PIR) [677.76 KB]

SPRA membrane manufacturers must have a comprehensive set of details that have been evaluated for buildability and performance. Some of our members are now offering Accredited Construction Details in respect of the Building Regulations AD Part L 1 & 2.
