Structure Layers Description of APP roof waterproof bitumen membrane with sand finish:
What is APP roof waterproof asphalt bitumen membrane 4mm thick with sand finish
Sand finished waterproof roll membrane is reinforced by polyster(PY) or fiber glass material(G), using APP modifying agent, upper surface finished with fine sand(S), lower surface with PE film.
APP waterproofing membranes provide superior tensile strength while maintaining critical flexibility – even in the coldest environments. Additionally, with APP roofing membranes (coated with a proprietary blend of asphalt and atactic polypropylene), contractors now have an efficient mode of application by heat welding.
The main advantages of our APP membranes include:
• 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
Our membranes conform to the: ISO 90001, CE Mark Compliance among other quality standards
