A new alliance has been formed - the Confederation of Multi-foil Manufacturers (CMM) - to represent the makers of these slender, lightweight insulation materials.
Their main concern is to counter recent guidance from the LABC (Local Authority Building Control), which recommends that the foils should not be used as standalone products. This is because the foils under-perform in tests - aimed at products that mainly cut down conductive heat losses - whereas multifoils primarily prevent radiative heat losses.
The CMM is arguing for a dynamic testing regime on specially constructed rigs.
Early tests show that in this environment, performance is at least comparable to that of conventional insulation materials. CMM hopes that the LABC guidance will not impede take-up of the material for roof insulation. For more information see www.confederationmultifoil. org

The Desirability of Sustainable Homes, Defra-funded MORI research by the Sponge Sustainability Network and Ipsos, was launched at the RIBA by the Minister for Housing and Planning, Yvette Cooper. Although lack of information is seen as a major barrier to increased demand for eco-homes, over half of those interviewed said they were willing to pay more for sustainable features. Nine out of 10 people think government should provide incentives. The full report is available for £40 or to download from www.spongenet. org
