Braid
Vapor permeable composite membrane with a three-dimensional net. The net is made of single, tangled polypropylene fibers, sealed at the points of contact, stabilized against UV radiation. The mat makes it possible to obtain a permanent drainage space between the wooden roof sheathing and the metal or wooden roofing. Used to dry the sheathing and eliminate excess moisture, as well as to prevent thermal warping and bulging of the roofing.
Advantages
- Allows ventilation of the roofing and drainage of condensed water coming from inside and outside the building
- Protects against corrosion by quickly draining water from under metal roofing
- It guarantees a ventilation space that allows excess heat dissipation
- Very easy installation
- It reduces noise during rain, which is of particular importance in attics
Usage
The braid is used between the wooden roof sheathing and the metal or wooden roofing to obtain a permanent drainage space. Used to dry the sheathing and eliminate excess moisture, as well as to prevent thermal warping and bulging of the roofing. Used mainly with zinc-titanium and aluminum roofing.
