HC Deb 20 December 1974 vol 883 c674W
Mr. Normanton

asked the Secretary of State for the Environment whether he is satisfied that materials required for thermal insulation in domestic building are in general free supply and not the subject of monopolistic manufacture.

Mr. Freeson

The new thermal insulation standards in the building regulations do not require the use of specific materials and there is a wide range of suitable products and construction methods which will meet these standards.
