vapor permeable roof membrane
Product Description
Kingway membrane is a breathable roof underlay that gives major benefits over traditional underlays.
The Kingway breather felt is made from two, high-tensile, spun-bonded polypropylene layers. This triple layer, high performance, breathable membrane is thermally calendared to a micro-porous polypropylene film.
- Layer one - waterproof surface
- Layer two - breathable waterproof membrane
- Layer three - protection from abrasion and damage, giving additional strength
Benefits
- Clean and easy to use
- Lightweight and flexible
- Waterproof membrane
- High vapour permeability
- Long-term durability and tensile/tear strength
- High wind uplift resistance
Application
Can be used in supported or unsupported roof systems, regardless of whether they are tile, slate or metal, and in warm and cold roof applications.
Equally effective whether draped unsupported over rafters, or laid directly onto insulation.
