Parafor 30 TG BW is a high performance, modified bitumen finish ply designed for use in homogeneous multi-layer modified bitumen roof membrane systems. Parafor 30 TG BW consists of a fiberglass scrim/polyester mat composite impregnated and coated with high quality styrene-butadienestyrene (SBS) modified bitumen, and surfaced with highly reflective, white mineral granules. The back surface is manufactured using a special process that embosses the surface with a grooved pattern to provide optimum burnoff of the plastic film and maximize application rates.
