Breathable synthetic roofing underlayment
Kingway membrane is our new synthetic roofing underlayment which carries on the well proven tradition of breathability. While most other underlayments do not breathe, Breathex does, allowing water vapour to escape from a roof deck. Breathex is the first modern underlayment which makes no sacrifices, bringing with it all the benefits of tradition, but made of truly cutting edge synthetic construction. Breathex is the next step in the evolution of roof protection.
It has three layers by Hot pressing composite technology:on the top and bottom is:polypropylene Spunbond non-woven fabric,between the two layers, is polyethylene material to form breathable film. The function of spunbonded nonwovens is mainly to enhance tension and hydrostatic pressure and protect the middle layer.
Breathable membranes can use as house wrap, a wall underlay membrane which functions as a weather-resistant barrier, preventing rain from getting into the wall assembly meanwhile allowing water vapor to pass to the exterior.
They may also act as windproof layer (Air barrier), reducing air leakage through the building envelope, ensuring insulation materials maintain their thermal efficiency by minimizing air infiltration
Breathable roof membrane is an extremely water resistant, airtight and vapour permeable membrane providing superior air and moisture management for commercial and residential buildings.
Breathable roof membrnae is a multi-purpose, durable and reinforced Tyvek grade for use in all supported and unsupported pitched roof applications, including warm, hybrid and cold roofs.
Quality roofing underlayment is critical for helping to prevent wind-driven rain from infiltrating under the roof's shingles and potentially damaging the home's structure and interior.
*Traditional asphalt felt underlayments can tear easily, absorb moisture, disintegrate and deteriorate much more quickly, leading to wrinkling and leakage through the main roofing cover.
*Synthetic Roof Underlayment is an innovated and specially designed 3-ply lightweight synthetic roofing underlayment that makes it a superior replacement for a traditional asphalt-saturated felt paper.
