Vapour barrier​s and membranes

A vapour barrier or vapour control layer stops moisture from passing through walls, floors, and roofs, preventing condensation that can cause damp, mould, and structural damage. These membranes are a vital part of insulation systems, helping to improve energy efficiency and protect buildings from moisture-related issues. Whether you're working on a new build or a renovation, choosing the right vapour barrier membrane ensures long-term performance and compliance with UK building regulations.

You’ll find vapour control membranes designed for different applications, from high-performance airtight solutions to breathable options that allow controlled moisture movement. Materials vary from polythene sheets to multi-layered foils, each suited to specific project requirements.
