Material meets the requirements of ASTM D 2178, Type VI
GlasPly Premier is intended for use as an interply in any built up roofing or modified bitumen roofing system.
Excellent Porosity: Allows the product to readily accept hot asphalt and disperse it throughout the entire felt, to stabilize the asphalt after cooling.
Asphalt Impregnated, Fiber Glass Reinforcement Mat: Delivers high tensile strength to resist splitting that can be caused by rooftop stresses. Low moisture, excellent dimensional stability and resistance to rot make it an ideal replacement for organic ply sheets. Provides a solid dimensionally stable substrate for other roofing membrane components.
Laying Lines: Before the product is wound into rolls, it is imprinted with laying lines on the top surface so the roofing mechanic can install the felt with the proper exposure and provide the correct number of plies
Surfacing: Liquid parting agent eliminates sticking when the felt is unrolled.
