Vapour Control Layers (VCL)

Vapour control layers (VCL) are sheets of material that prevent water vapour from accumulating in the structure of a building. When condensation builds up in properties it can lead to the development of dampness, mould and rot, which can cause both structural and health issues. VCLs can help to rectify these.

VCL membranes work by preventing water from condensing and forming surface water. Typically installed on the warm side of the insulation, the VCL blocks warm, moist air from entering the roof space. When used in conjunction with good ventilation and the installation of an exterior breather membrane, moisture particles are free to escape from the inside, while adverse weather is prevented from entering.

At Insulation Superstore, we offer a wide range of vapour membranes. From large-scale building projects to small-scale renovations, our vapour control layers are reliable, and trustworthy and have been manufactured by industry-leading experts.
