StressPly IV Plus membranes are a premier, rubber-modified roof cap sheet engineered for high-performance torch applications. These 180-195 mil membranes combine a high percentage of premium Styrene-Butadiene-Styrene (SBS) rubber with a dual-composition reinforcement of polyester and fiberglass. This synergistic blend delivers exceptional tensile strength and long-term durability for the most demanding building envelopes.

Reinforced with a highstrength polyester/fiberglass scrim, StressPly IV Plus delivers tensile strength exceeding 300 lbf/in in both machine and cross-machine directions. This robust reinforcement provides unmatched resistance to splits and tears. Infused with elite SBS polymers, the membrane maintains superior low-temperature flexibility and elastomeric recovery throughout its service life.
The StressPly IV Plus UV Mineral variant utilizes our bright white Sunburst™ mineral. This advanced surfacing provides long-term UV protection and substantial energy savings by decreasing under-roof temperatures and preventing premature membrane aging.
The specialized backing is optimized to melt in perfect synchronization with the compound’s softening point. The Garland logo print provides the applicator with an immediate visual cue, ensuring a secure, monolithic bond to the substrate.
