DynaBase® PR
DynaBase® PR is a modified bitumen sheet incorporating the features of a polyester mat with a blend of SBS (Styrene-Butadiene-Styrene) rubber and high quality asphalt. The elastomeric asphaltic blend has full recovery properties after 100% elongation and lends elasticity and flexibility to the sheet. The polyester mat provides good tensile strength, toughness, puncture resistance and can accommodate stress created by typical rooftop expansion and contraction forces. A fine material parting agent is applied to both sides of the product.
DynaBase PR is used in multi-ply modified bitumen membranes. It may be used as the base ply when installed over a JM Roofing Systems insulation. It may also be used as a base/ply sheet over insulated systems employing a traditional fiber glass ply felt or over nailable substrates with or without a standard fiber glass base felt, such as GlasBase.
