DynaFast 250 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.
Heavy Duty Polyester-Reinforcement Mat: Provides excellent tensile strength, toughness, and puncture resistance and can accommodate stresses created by typical roof top expansion and contraction forces.
Polyolefin Burn-Off Film: Promotes ease of heat welding.
