High-Quality SBS Rubber and Asphalt Blend: Provides full recovery properties after 100% elongation and lends elasticity and flexibility to the sheet.
Polyester-Reinforcement Mat: Polyester mat with bi-directional glass-scrim reinforcement offers robust tear strength and puncture resistance, allowing for high wind performance and an excellent hail rating. The sheet also exhibits strong dimensional stability and enhanced elongation.
Polyolefin Burn-Off Film with a Self-Adhering Modified Bitumen: The top side polyolefin burn-off film promotes ease of heat welding for installation of a heat-welded cap sheet such as DynaWeld Cap 250. The bottom side has a self-adhering surface with an easy-to-peel plastic film sheet that allows for installation without the need of hot asphalt or heat welding.
