Cromar Vent 3 Breather Membrane (50m Roll)

Vent3 is a high-performance, triple-layer fabric breather membrane designed to be used in fully supported or unsupported tiled, slated, or metal roof systems. It is made of high-tensile spun-bonded polypropylene layers, surrounding a micro-porous polypropylene film. The triple-layer structure ensures that the outer layer is waterproof, the middle layer is breathable, and the inner layer protects the membrane from abrasion and damage. This combination allows for moisture vapour to pass through while remaining fully waterproof. The high vapour permeability, excellent tensile/tear strength, and high wind uplift resistance make Vent3 the ultimate choice as the ultimate breather membrane. It can be draped unsupported over rafters or laid directly over insulation or sarking boards. Vent3 is lightweight, flexible, is also UV-stable for up to three months and is suitable for both warm and cold roof applications.

Features:

  • Triple-layer high-performance breather membrane
  • Suitable for fully supported or unsupported roofs
  • High vapour permeability and waterproof properties
  • Excellent tensile/tear strength and wind uplift resistance
  • UV stable
