Keep pitched roof constructions protected with Cromar Vent3 Pro Green, a breathable roofing membrane suitable for installation beneath tiles and slates. Its vapour-permeable construction allows moisture vapour to pass through the underlay, helping to manage condensation within the roof space while maintaining an effective secondary weather barrier. Lightweight construction makes the membrane straightforward to handle, position and cut on site, helping roofers and builders work efficiently across larger roof areas. It provides protection against wind-driven rain, snow and dust that may penetrate the primary roof covering, contributing to a durable and effective roofing system. At 1.5m wide, this version offers greater coverage with each run compared with narrower roofing membrane rolls. The 50m roll length provides 75m² of gross coverage, making it a practical option for new roofs, extensions and refurbishment projects.
