Build November_2016

Build Magazine 19 Construction no structural strength to stabilise roofs or walls and are widely marketed to be applied directly onto non-breathable membranes. This practice should be treated with a high degree of caution as interstitial condensation could occur in the foam, next to roof timbers. However, they are better suited for their enhanced sound attenuation properties. Open cell foam is also useful in situations which require more air and vapour into a building’s interior. Where open cell materials are used, the installation thickness can be increased for better thermal performance but if the primary purpose is energy efficiency, then the closed cell option is normally preferable. BUFCA celebrated its 30th anniversary in March 2016. Peter Bristow, the BUFCA Chairman explained, “As a small trade association, we are pleased to have reached this important milestone – now we can build on our solid foundations to further develop the polyurethane foam market across a range of sectors. Insulation of the building fabric has the most potential to make energy efficiency savings in the UK, improve comfort and reduce the carbon footprint. The walls and roof are normally the greatest areas of heat loss.” The British Urethane Foam Contractors Association represents sprayed and injected polyurethane foam installers.
