StressPly® FR Mineral

  • Security in Multi-Ply Construction
  • Reduced Labor Expenses
  • Superior Strength

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

Security in Multi-Ply Construction

StressPly membranes are the top component of a multi-ply roof system. It combines the advantages and proven performance of multiple protection with the strength, flexibility, and elongation of elastomeric systems. This unique combination eliminates dependence on perfect workmanship, contact adhesive seaming, etc.

Factory Formulation Reduces Labor Expenses

StressPly membranes are coated at the factory with reflective mineral granules. Consequently, there’s no need to flood coat and gravel or aluminize the membrane’s surface. Roof projects can be completed on a more timely basis. The result is substantial labor expense savings.

Superior Strength

The StressPly membranes are reinforced with two layers of fiberglass. The superior strength provided by the dual fiberglass scrim resists the movement created by today’s modern buildings. In addition, the dual fiberglass scrim in StressPly membranes provides tensile strength in excess of 200 pounds per inch in the machine and cross-machine direction. This translates to long-term resistance to splits and tears in the completed StressPly roof system.
