Breathable HouseWrap, also call homewrap, Weather Protection Barrier or Breathable Membrane which is a water resistant membrane with high vapour permeability, use as diffusion open roofing felts under pitched roof tile or vapour permeable barrier housewraps on timber frame walls.

It functions as a weather-resistant barrier, preventing rain from getting into the roof or wall assembly while allowing water vapor to pass to the exterior. Breather House Wrap may also serve as an air barrier if it is sealed carefully at seams.It also have good "water resistance", good "water vapor permeability", and good "air barrier properties"..

Material: 3 Layers, middle layer polyolefin microporous membrane and two layers of polymer material produced by advanced thermal composite craft

Material Specification:


    - Completely waterproof: As it provides the building's exterior with superior waterproofing functions, it improves the building's durability.
    - Enhancement of energy efficiency: With superior waterproof and windproof properties, it increases the efficiency of air cooling and heating of the house, thereby offering great energy savings.
    - Superior humidity permeability: As moisture inside building is effectively allowed to permeate outward, it prevents the degradation of the building due to moisture.
    - Prevention of ultraviolet rays: Using UV processed film to prevent oxidization due to the exposure to ultraviolet rays during the building's construction period, it maximizes the durability of the building.
    - Environment-friendly: It has superior durability and can be used for a long time with a single implementation, making it environment-friendly.
    - Easy to cut and install: Lightweight and easy to cut, it is easy to work during the building construction.

General Applications:

The purpose of the membrane is to allow water vapour to permeate through from the insulation into the cavity above and yet prevent water from the cavity entering the quilt. Breather membranes are installed over the top of quilt insulation and below the external profiled sheet.
