Daltex® Vapour Control Layers are high resistance vapour barriers specifically designed to reduce the transfer of water vapour through the building or structure when placed on the warm side of the insulation. Daltex® VCL products are ideal for use in a range of construction applications including walls, ceilings, and floors.

In addition to our standard VCL products, our reflective vapour control layer is a nonwoven composite fabric incorporating a highly reflective, low emissivity foil. This product offers exceptional performance as an air and vapour barrier. The reflective surface assists in enhancing overall thermal performance in the adjacent cavity.
