List of featured suppliers of MEMBRANES Vapour Permeable on Building Products Index
Membranes that are permeable to vapour allow water molecules to pass through while blocking larger molecules or substances. This characteristic is important in applications where it is desirable to prevent moisture buildup, such as in insulated walls or roofs. Vapour permeable membranes can be made from a variety of materials, including fabrics, films, and other synthetic materials. They are typically installed on the warm side of insulation to allow water vapour to escape and prevent condensation from forming within the construction assembly.
