Abstract
This paper describes a novel water-permeable vapor retarder that can help solve some of the moisture problems that frequently occur in certain roof and wall constructions. Preliminary results are given from investigations on moisture movements in exterior wood frame walls carried out in a climate simulator. Three different walls have been investigated: one with a polyethylenevapor retarder on the inside, one with a water permeable vapor retarder on one side of the insulation layer, and one with water permeable vapor retarder on both sides of the insulation layer. Results are given from measurements in a small test hut on the seasonal variation of moisture content of a number of roof segments with different vapor retarders, with or without a plywood deck between the insulation and the roof membrane.
