Features and Components
APPeX 4.5M CR G is used as a polyester-reinfored cool roof cap or flashing sheet in APP multi-ply roofing systems.
Reflective Roofing Granules: Specifically engineered for high reflectivity, durability and optimal embedment in the APP modified bitumen sheet.
APP (Atactic Polypropylene) Polymer and Asphalt Blend: Provides an extremely durable sheet with excellent weathering characteristics, flexibility and dimensional stability for ease of handling and quick installations.
Polyester Reinforcement Mat: Provides bidirectional glass-scrim reinforcement and offers robust tear strength and puncture resistance, allowing for high wind performance and excellent hail rating. The sheet also exhibits strong dimensional stability and enhanced elongation.
Polyolefin Burn-Off Film: Promotes ease of heat welding.
