Vapour Control Layers

Vapour control layers help manage the movement of moisture within roof and wall constructions, reducing the risk of condensation and protecting insulation from damp. Installed on the warm side of the insulation, these membranes play an important role in improving the performance and longevity of both pitched and flat roofing systems.

Our range includes vapour control barriers suitable for residential and commercial roofing projects, with products designed for compatibility with a wide variety of insulation systems and roof build-ups. Durable and easy to install, these membranes help improve airtightness while supporting compliance with modern building regulations and energy efficiency requirements.
