Spunsulation Undertile Membrane
Spunsulation Undertile Membrane is suitable for installation under all types of roof tiles in a conventional manner in all areas of South Africa.
It reduces air movement between tiles, since the membrane can contribute to maintaining a balanced air pressure on both sides of the roof tiles, and it also reduces ingress to the roof space of wind-driven rain and dust.
The undertile membrane is manufactured from two layers of cross-woven, spunbonded virgin polypropylene coloured blue and charcoal. The two spunbond layers are heat-bonded together with an interlayer of polymer.
The spunbond layers are UV stabilised. The membrane has a weight of 100 g/m2 and is supplied in rolls 30 m long and 1,5 m wide.
