HC Deb 25 March 1969 vol 780 cc247-8W
54. Mr. J. H. Osborn

asked the Minister of Housing and Local Government what is his estimate of the import saving per year of timber, arising from all public authorities specifying metal or plastic windows instead of wooden windows in their housing programmes.

Mr. MacColl

The import saving would be about £15 worth of timber per house. I cannot estimate the total saving since the number of houses built with wooden windows is not recorded.

55. Mr. J. H. Osborn

asked the Minister of Housing and Local Government if he will review design, methods of construction, maintenance, capital cost and performance through the Building Research Station, or other Government organisations, of the various types of window available for house construction, including those made in ferrous-aluminium and non-ferrous materials or wood.

Mr. MacColl

The various types of window available are being examined by the Department for their use in housing and by other Departments for use in other buildings. The Building Research Station is associated with these examinations as are local authority and other interests.
