Easy Trim Master Breather Membrane 50m x 1.5m (75m2/Roll)

Easy Trim Master Breather Membrane in a 50m x 1.5m roll, providing 75m² of coverage, designed as a high-performance breathable underlay for pitched roofs and timber frame walls.This advanced membrane delivers dual functionality: it prevents external water ingress while allowing internal moisture vapour to escape. By maintaining this critical balance, the membrane safeguards roof structures from condensation-related damage, including timber decay, insulation deterioration, and mould growth.Suitable for use in warm, cold, and hybrid roof constructions, it performs consistently in both fully supported (direct to sheathing boards) and unsupported (draped between rafters) applications. Its wider 1.5m format minimises overlaps on large roof areas, reducing waste and improving installation efficiency.The membrane is engineered to withstand all five wind zones defined by BS5534:2014 Annex A, meaning it can be confidently specified for both sheltered inland properties and exposed coastal or high-altitude locations.
