Roofproof 400 Non-woven Undertile Membrane is manufactured from three layers of polymer laminated together. The laminates are UV and heat stabilised. The membrane has a mass of 100g/m?.
Roofproof 400 Non-woven Undertile Membrane is suitable for installation in all tiled-roof buildings with timber roof construction having a pitch less than 60 degree. It was not evaluated for metal roof construction and side-wall cladding. It can be used in the conventional manner to:
- reduce air movement between tiles, since the membrane can contribute to maintaining a balanced air pressure on both sides of the roof tiles
- reduce the ingress into the roof space of wind-driven rain and dust.
