APP Modified Bitumen Roll Sheet is a plastic bitumen blend, which is modified using plastic in the form of atactic polypropylene (APP). As installers begin to torch-apply APP, this type of plastic begins to melt at a point of 300F, where it melts into a liquid wax like substance which acts as an almost free-flowing liquid which can then be mopped across a surface. APP has a high temperature tolerance when heating, so is more user-friendly for installers.
This ease of melting makes APP bitumen popular on smaller roofs such as residential properties and commercial flat roofs.

The main advantages of our APP membranes

• Enhanced bitumen performance by increasing UV resistance
• Increasing flexibility at low temps
• Improving flow resistance at high temps
• Excellent weathering
• Fire resistant properties
• Climate adaptability
• Applicable on all sloping surfaces: on flat, vertical and curved surfaces.
• Excellent product for all weather conditions.
• Lightweight: prevents any excessive weight on the roof or the building structure.
• Good resistance to fatigue and tear.
• Longer lasting product (up to fifteen years)
