SBS (Styrene-Butadiene-Styrene) Synthetic Rubber and High Quality Asphalt Blend: Brings elasticity and flexibility to the sheet; lays flat virtually eliminating wrinkles resulting in fast, efficient applications.

Fully-Coated Mat: No pinholes prevent asphalt bleed-through, eliminating splitting problems associated with excessive membrane attachment to nailable decks. Excellent nail retention properties and resistance to uplift forces. Virtually eliminates wrinkling, resulting in fast, efficient applications.

Non Porous Composition: Allows the product to be used as a ply sheet in systems that employ cold process mastics such as JM BUR Adhesive.

Fiber Glass Reinforcement Mat: Low moisture, excellent dimensional stability and resistance to rot make it an ideal replacement for organic base sheets. Provides a solid dimensionally stable substrate for other roofing membrane components.

Surfacing: Fine mineral parting agent
