DuroTorch 3 MM - APP Compound High Strength Polyester
DuroTorch 3MM is a bituminous, plastomeric, torch on sheet membrane. It is manufactured from a compound based on a selected distilled bitumen modified with polypropylene polymer bitumen (APP) and reinforced with a high strength non-woven polyester fabric. The combination of high performance polymer bitumen and 160gsm non-tear polyester reinforcement provides a durable system ensuring good flexibility at low temperatures and excellent heat resistance.
The DuroTorch range is manufactured under ISO 9001 Total Quality guidelines.
Duro Torch 3mm exhibits both excellent dimensional and mechanical stability, making it particularly suitable for waterproofing civil, industrial and residential building projects. It is often used as the base layer of a multi layer membrane system.
The underside of DuroTorch 3MM is finished with a thermofusible film, which melts upon torching, ensuring a clean application. Surfaces to be waterproofed should be dry, clean, smooth and free of protrusions. All surfaces should be primed with Duroproof Bitumen Primer. The membrane is torched on with minimal use of a propane gas flame, making it easy and quick to apply. Apply heat to the underside of the membrane and melt down part of the bituminous undercoating. Form overlaps along the side of 8-10cm and 12-15cm laps at the ends.
Keep the product away from solvents and organic liquids as they may damage the product. When laying the membrane, the surface must be free from any items which may puncture the membrane. Do not apply in rain or if the temperature is below 5 C. Store rolls in upright position. When unloading avoid impact damage.
