Cromar Vent 3 Breathable Roofing Felt Membrane – 1m x 50m Roll

Cromar Vent 3 is a triple-layer fabric, high-performance Breathable Roofing Felt Membrane, made from high-tensile spun-bonded polypropylene layers, around a microporous polypropylene film. Designed for use in a fully supported or unsupported tiled, slated or metal roof system. The high vapour permeability and waterproof nature of the Cromar Vent 3 roofing membrane, combined with excellent tensile/tear strength and high wind uplift resistance, make Cromar Vent 3 roofing felt the professional’s choice as the ultimate breather membrane. It is equally suitable whether draped unsupported over rafters or laid directly over insulation.

The outer layer forms the functional waterproof surface, the middle layer is the breathable waterproof membrane, and the inner layer protects the membrane from abrasion and damage, also giving additional strength. This enables the fabric to allow moisture vapour to pass through, whilst remaining fully waterproof.

• BBA certified
