Vent3 Classic Breathable Membrane

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.

Vent3 has become the number one choice for professionals due to its high vapour permeability and waterproof nature of the membrane, combined with excellent tensile/tear strength and high wind uplift resistance. Together it makes Vent3 Classic the professionals 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.

Vent3 Classic is BBA certified, is easy to use, offers great nail tear resistance and will be UV stable for up to 3 months from the initial time of installation.

Vent3 Classic has a printed light Grey upper surface and white under-face and has a weight of 115gsm.
