StressPly membranes are high-strength, puncture, and fatigue-resistant, rubber-modified roof membranes designed as the waterproofing and reinforcement layer of a modified built-up roofing system. It consists of two layers of fiberglass reinforcement sandwiched by Styrene-Butadiene-Styrene (SBS) rubber in a high penetration index asphalt mixture. StressPly membranes are designed as the top component in a roofing system where fire retardancy is required. StressPly membranes can also be used with Garland’s HPR® products and conventional glass base sheets or fiberglass roofing felts. In addition, StressPly membranes can be used as the top ply in a two-ply flashing system. It can also repair splits, cracks, and other deteriorated areas in existing asphalt-based roofing systems. Specifications are available for either hot or cold-applied systems. * Garland Greenhouse® product
