DynaBase PR - SBS Roofing Systems

Polyester-reinforced SBS base or ply sheet.

Meets the requirements of ASTM D 6164, Type 1, Grade S

DynaBase PR is used as a polyester-reinforced base or ply 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.

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.

Surfacing: Fine mineral parting agent on both sides.
