Flat areas : 1.15 M² /M² per layer with 10 cms. Side laps and 15cms. end Laps.

Torching Guidelines

The underside of the membrane should be torched just enough to superficially melt the bitumen. Excessive heating may damage the re-enforcement.
Overlaps should be re-heated from the top and resealed with a trowel to ensure seam integrity.
