This breathable roofing felt is made from high tensile spun bonded polypropylene layers, around a micro-porous polypropylene film. It has triple layer breather membrane is avilable in 1x50mtr and has been designed for use in a fully supported or unsupported tiled, slated or metal roof system.

• High vapour permeability
• Waterproof membrane
• Excellent tensile/tear strength
• Highwind uplift resistance

Use directly over insulation or draped unsupported over rafters. Additional strength given due to its layers:

• Outer layer.
  • Forms the functional waterproof surface
• Middle layer
  • This is the breathable waterproof membrane.
• Inner layer
  • Protects the membrane from abrasion and damage

This enables the fabric to allow moisture vapour to pass through, whilst remaining fully waterproof.
