Our higher grade polythene Vapour Control Layer, for use within the walls of timber frame constructions, or where the control of the passage of water vapour is required. CE approved and CPR compliant.

A 1200 gauge virgin grade polythene VCL for use in timber frame constructions, or other applications where the control of water vapour is necessary. This product is CE Approved to EN 13984:2013.

VCL’s are designed for use on the inside (warm side) of insulated buildings to manage the flow of water-vapour, which is a natural by-product of normal building use. Without the use of these membranes within the construction, there is significant risk of condensation within the building structure, potentially leading in the long-term to building damage, and in the short term to substantially increased heating and cooling costs. As little as 3% moisture deposited within the building’s insulation, has been shown to negatively affect insulation performance by up to one third.
