Bison House Wrap 100 consists of two layers of polypropylene with a waterproof polyethylene foil in the middle. The house wrap is UV-stabilized.
Bison House wrap 100 is open to diffusion, which means that any moisture can migrate out of the material. The material is windproof and the outside is water repellent. The membrane is mounted on the outside of the insulation, inside the surface layer (facade).
The house wrap is used to protect the insulation from wind and thereby ensuring that the insulation is not impaired. It also prevents any moisture, which can be found behind the facade, to penetrate into the insulation. These features prevent moisture problems.
