DynaMax Smooth is used as a premium fiber glass/ polyester-reinforced modified bitumen base, ply, or cap sheet in a variety of multi-ply roofing 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.
Fiber Glass/Polyester Reinforcement Mat: Combines the excellent tensile strength, toughness and puncture resistance of a polyester mat with the dimensional stability and lay-flat characteristics of fiber glass.
Surfacing: A fine material parting agent is applied to both sides of the product.
