Atactic Polypropylene (APP) modified bitumen roofing membranes offer superior durability and weather resistance, making them ideal for commercial and industrial applications. Constructed from high-quality APP materials, these membranes feature reinforcement with polyester or fiberglass mats to boost strength. They serve as a dependable barrier against external elements, offering superior water resistance and adaptability to temperature fluctuations.
When utilized within a multi-ply roofing system, APP membranes establish a watertight layer that safeguards the building’s structure and interior from potential water damage. They are also appropriate for industrial environments and residential projects where conventional roofing solutions may fall short. The membranes are available in rolls, each measuring 10 meters by 1 meter, covering an area of 8.7 m².
