Vapour Control Layers

The most effective way to avoid condensation in roofs is to prevent as much water vapour as possible reaching the cold side of the thermal insulation. This can be achieved simply and cost-effectively by using a vapour control layer on the warm side of the thermal insulation.

A wide range of vapour control solutions are available for both domestic, commercial and industrial use.
