They are typically installed in the wall, roof, or floor assembly of a building and act as a barrier to prevent moisture from entering or leaving the interior space. VCLs can be made from a range of materials, including plastic, foil, or coated paper, and are often used in conjunction with insulation and air barriers to create a complete building envelope. By controlling the movement of water vapour, membranes, VCL can help improve the energy efficiency, durability, and indoor air quality of a building.
