StressPly® IV Plus / IV Plus Mineral / IV Plus UV Mineral

  • Superior Strength & Weatherability
  • Unmatched Reflectivity
  • Reduced Labor Expenses

StressPly IV Plus membranes are high-strength, polyester/fiberglass reinforced, rubber-modified roof membranes designed for torching applications. The 180-195 mil membranes offer high strength and a high percentage of quality blended Styrene-Butadiene-Styrene (SBS) rubber compound. StressPly IV Plus membranes incorporate a polyolefin backer to indicate when proper heat is obtained during application. StressPly IV Plus membranes can be used with Garland’s HPR® products, conventional glass base sheets, or fiberglass felt underlayment. In addition, StressPly IV Plus membranes can be used as the top ply in a two-ply flashing system. It can also repair splits, cracks, or other deteriorated areas of existing modified roof systems.

Superior Strength & Weatherability

The StressPly IV Plus membranes are reinforced with a high-strength, polyester/fiberglass reinforced scrim. The superior strength provided by the polyester/ fiberglass scrim in StressPly IV Plus membranes provides tensile strength in excess of 300 pounds per inch in the machine and cross-machine direction. This translates into long-term resistance to splits and tears in the completed StressPly IV Plus roof systems. The high-quality SBS rubber polymer in StressPly IV Plus offers unmatched low-temperature flexibility, weathering, and elastomeric properties.

Unmatched Reflectivity

The StressPly IV Plus UV Mineral membrane incorporates the unique mineral, providing long-term protection and energy savings. The superior reflectivity of this mineral protects the StressPly IV Plus UV Mineral membrane from UV damage and decreases under roof temperatures.

Factory Formulated Reduces Labor Expenses

StressPly IV Plus Mineral and StressPly IV Plus UV Mineral are coated with reflective mineral granules at the factory. Consequently, there’s no need to flood coat and gravel or aluminize the membrane’s surface. Roof projects can be completed more timely—result: substantial labor expense savings.
