§ 81. Mr. Sorensen
asked the Minister of Public Building and Works to what extent substitutes for bricks are now being used in the building of domestic dwellings; how the substitutes compare by experience with bricks; and whether the supply of adequate substitutes can be expanded during the next 12 months.
§ Mr. C. Pannell
Alternative materials, most of them satisfactory, are being used to an increasing extent. For example, it is becoming more and more common to use blocks in place of bricks for the inner leaf of a cavity wall, and this is recognised as sound practice. The 45W demand for both bricks and other walling materials is likely to continue to grow and I expect production to increase substantially next year.
