Cromar Breathable Vent 3 High Performance Felt 50m x 1m (Blue)

Breathable felt is a vital component of modern roofing systems. Installed directly onto rafters beneath tiles or slates, it acts as a protective barrier against wind-driven rain and snow while allowing moisture and condensation from within the roof structure to escape. This essential function helps prevent timber decay and preserves the performance of insulation over time.
