DynaWeld GL 2.2 P/P

DynaWeld™ GL 2.2 P/P is a fiber glass-reinforced SBS modified bitumen flashing base sheet. It incorporates the features of a strong fiber glass mat that is saturated and coated with a blend of SBS rubber and high-quality asphalt. The elastomeric asphalt blend has full recovery properties after 100% elongation and lends a high degree of elasticity and flexibility to the sheet. The inorganic fiber glass reinforcing provides high tensile strength, stability and toughness to the product and resists moisture absorption. Both sides of the sheet have a polyolefin burn-off film for ease of heat welding.
