§ Sir D. Walker-Smithasked the Secretary of State for the Environment whether he is satisfied that sufficient resources exist for insulation of buildings by way of cavity infill; and whether the money expended on publicity schemes for its promotion has been justified in view of the limitation of supply.
§ Mr. ArmstrongYes. I am assured that there is sufficient capacity in the industry to meet any likely level of demand. I do not know of any general limitation of supply that would nullify the effect of the resources expended on its promotion.
