Vent3 Classic High Performance Breathable Membrane 50 x 1.5Mtr
Vent3 Classic 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 Classic 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
This roll is a standard 1.5m wide to conform easily to any typical roof configuration or the individual working practices of the installer
