ABSTRACT
In a Danish housing estate moisture sensors have been installed in 32 dwellings part in walls and part in roofs. The walls and roofs were insulated with cellulose insulation and were either with or without PE-vapour barriers. In the paper is described the results from moisture measurements during two winters. Also the indoor climate has been recorded in the dwellings. The result was that under Danish conditions neither the moisture conditions in walls and roofs nor the indoor climate depended on whether a PE-vapour barrier was used or not.
