Type of article: Article

Summary

Questions the assumptions commonly made in working models about thermal insulation and ventilation in pitched roofs and the mechanisms of heat conduction and vapour diffusion plus the efficacy of vapour barriers. Questions the value of having two ventilated spaces in a roof construction, particularly for the case of mineral wool insulation. Concludes that the classical model of heat conduction and vapour diffusion and ventilation should be re-examined very thoroughly.
