Combining the use of self-adhesive membranes, hot air welding and solvent-free adhesives, Stress Ply Flex SA System is a flame-free modified bitumen system.

The system features the same durability and robust waterproofing benefits as multi-ply torch-on bitumen membranes, without the need for naked flame.

The membrane laps feature a self-adhesive compound technology, allowing laps to be partially sealed without the need for flame and does not risk burning heat-sensitive insulation board or combustible deck materials during the hot-air welding process.
