DynaBase HW - SBS Roofing Systems
Fiber glass-reinforced SBS base or ply sheet.
Meets the requirements of ASTM D 6163, Type 1, Grade S
DynaBase HW is used as a fiber glass-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.
Fiber Glass Reinforcement Mat: Offers excellent dimensional stability and tensile strength and withstands differential movement. Because it has no thermal memory less time is needed to relax the sheet, allowing for ease of installation. The fiber glass mat also has good lay-flat characteristics.
Surfacing: Fine mineral parting agent on the top side of the sheet. A polyolefin burn-off film on the bottom side enables the product to be applied using heat welding techniques.
