§ 21. Dr. Brayasked the Minister of Housing and Local Government and Minister for Welsh Affairs whether he will set minimum standards for heat insulation in new houses.
§ Sir K. JosephSuch standards are already set by building byelaws.
§ Dr. BrayIs the right hon. Gentleman aware that they are not high enough and that, for example, the cost of double glazing very much depends upon the volume of production? If manufacturers could be sure of a mass market the cost of this undoubtedly extremely useful provision would be reduced enormously.
§ Sir K. JosephMy right hon. Friend the Minister of Public Works and Buildings and I are awaiting the Report of the Building Regulations Advisory Committee on which we shall base the national building code which is to replace byelaws later this year.
