Description

The VELUX Vapour Barrier 134x98cm BBX UK04 0000 is a polyethylene film membrane designed to control moisture and reduce condensation risk in building construction. Commonly used in cavity wall applications, it provides a reliable barrier against moisture ingress, helping to protect walls and floors from moisture-related damage. When installed correctly to current site practice and manufacturer guidance, the vapour barrier can help reduce energy loss and extend the lifespan of building materials. Suitable for both new build and retrofit projects where moisture control is required. Always confirm product dimensions and grade against your project specification before ordering, and use appropriate fixings for secure installation.
