§ Mr. Harry GreenwayTo ask the Secretary of State for the Environment what consideration he gave to proposing improvements to wall insulation in his Department's consultative document on building regulations (conservation of fuel and power); and what public guidance he gives on cavity wall insulation.
§ Mr. BaldryThe current proposals for revising part l of the Building Regulations would significantly improve wall insulation taking the fabric of the wall as a whole. In particular the proposals would no longer allow lower standards of wall insulation where double glazing is fitted.
The Department's Building Research Establishment has produced a number of publications over the years on cavity wall insulation and made contributions to publications produced by for example the British Standards Institution, and the National House-Building Council. Two of its publications are:
Report No. 143 "Thermal insulation avoiding risks"; and NHBC Good Practice Guide: "Thermal insulation and ventilation".
