Housing: Insulation

Volume 475: debated on Monday 12 May 2008

To ask the Secretary of State for Communities and Local Government if she will issue guidance to (a) home improvement agencies and (b) other agencies responsible for introducing energy efficiency measures on the effect of different weather conditions on older Bradstone-built houses when adapting those houses through the installation of cavity wall insulation. (204674)

The Department for Communities and Local Government has no plans to issue further guidance on cavity wall insulation beyond that which already exists within the Building Regulations Part C—site preparation and resistance to contaminants and moisture. This indicates that the complete filling of cavities in a cavity masonry wall, for all property types, is not recommended in certain locations and under certain weather conditions.

Further guidance on the installation of cavity wall insulation is provided by the Energy Saving Trust and also within Building Research Establishment’s booklet BR 262—Thermal insulation: avoiding the risks.
