§ Mr. Skeetasked the Secretary of State for the Environment what information he has as to the extent to which wall insulation materials, including a variety of foams, have led to damp penetration on the inner walls of buildings in general and houses in particular.
§ Sir George YoungThe Building Research Establishment has carried out tests on damp penetration through cavity walls before and after insulation with a variety of materials. Filling cavities can increase damp penetration in some circumstances, but generally the risks arising from insulation properly installed in accordance with the appropriate agrément certificate or British standard are outweighed by the benefits of increased comfort and reduced energy consumption.
