APP Modified Bitumen Membrane.

Nonwoven  Polyester 150 g/m² Reinforcement.


Torch applied waterproofing membranes, modified with atactic poly-propylene (APP). The membrane has excellent durability and flexibility at low temperatures, and ability to withstand high temperatures.

The nonwoven polyester reinforcement gives the needed elongation and provides the membrane with the required resistance to heat aging, puncture, and rotting.

The upper face is covered with polyethylene film, granules or colored slates.
