Multi Buy - 12 x Cromar Vent 3 Pro 1m x 50m (50m2)

Cromar Vent3 PRO Breathable Membrane is a triple layer fabric, high performance breather membrane, made from high tensile spun bonded polypropylene layers, around a micro‐porous 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 membrane combined with excellent tensile/tear strength and high wind uplift resistance make Vent3 the professional’s choice as the ultimate breather membrane.
It is equally suitable whether draped unsupported over rafters, laid directly over insulation or sarking boards (Scottish Practice). 
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.

The upper surface is Blue, printed with the trade name and head lap lines.
