Remedies for condensation and mould

Surface condensation and mould affect about 15 percent of the UK housing stock. This paper reports BRE studies in occupied dwellings on the effectiveness in various situations of a range of remedial measures, which included improvements to thermal insulation and heating, and the provision of extractor fans and dehumidifiers. The flats and 2-storey houses involved were all of traditional construction with brick walls and pitched roofs. The results are incorporated in a recently published BRE package of practical guidance; this article outlines significant factors revealed by the field studies.
