A vapour barrier is a critical component in flat roof construction, designed to control moisture from within the building before it can enter the roofing system.
Installed beneath the insulation, it helps prevent condensation build-up that can lead to damp, reduced thermal performance, and long-term structural damage.
Whether you're working on a warm roof or refurbishment project, vapour control layers play a key role in protecting your flat roof system, improving energy efficiency, and ensuring long-lasting performance.
