Elastomeric, bituminous membrane reinforced with non-woven, polyester fabric of 150 g/m2. The upper membrane is covered with an aluminium sheet and the lower membrane is covered with a thin film of polyethylene, which is easily torched. At the one edge of each membrane there is a margin (10 cm width) without aluminium cover, which enables covering with adjacent membrane sheets. It shows excellent strength and provides absolute waterproofing.
