Loft insulation and condensation in roof spaces

Abstract

A discussion meeting attended by an invited audience of some thirty people was held at the Chartered Institution of Building Services on 15 July 1981. The audience comprised researchers, consulting engineers, architects, insulation manufacturers and contractors and management personnel from both the public and private sectors of housing. The object of the discussion was to ascertain the extent of the problem of condensation in roof spaces of dwellings insulated to higher than traditional standards as evident now, to discuss the mechanisms resulting in condensation and to evaluate possible solutions. In addition, an attempt was to be made to assess the consequences in, say, ten years' time of the trends.
