vapor permeable roof membrane packing in rolls in bags
vapor permeable roof membrane
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
Clean and easy to use
Lightweight and flexible
High vapour permeability
Long-term durability and tensile/tear strength
High wind uplift resistance
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.
