DynaFast® 180 HW is a heat weldable base or ply sheet for use in mechanically fastened systems.
High-Quality SBS Rubber and Asphalt Blend: Lends elasticity and flexibility to the sheet. The elongation and recovery properties allow the product to easily accommodate the continual expansion and contraction experienced on all roofs.
Polyester-Reinforced Mat: Polyester mat with bidirectional 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: Promotes ease of heat welding.
