§ 10. Mr. N. Pannellasked the Parliamentary Secretary to the Ministry of Works, as representing the Lord President of the Council, what advice the Department of Scientific and Industrial Research has to offer to prevent or cure the problem of widespread damage to flues in houses with small domestic boilers.
§ Mr. H. NichollsThe Building Research Station of the Department has shown that chemicals in condensed moisture in the flue cause distortion of stacks and staining of inside and outside walls and attack the mortar, crack the brickwork and cause the rendering to fall away. The trouble is best avoided by providing an impervious lining to the flue whenever possible.
§ Mr. PannellWill my hon. Friend ensure that the widest publicity is given to his reply? What steps is he taking to enlist the support of the building trade in the solution of this problem?
§ Mr. NichollsThe Department knows that this is a troublesome point and has let the architects and all the building organisations have all the knowledge which it has acquired from this research. Indeed, the building industry is working on the problem, too.
