The Garland Company, Inc., manufacturer and distributor of high-performance solutions for the commercial building envelope, recently raised the roofing industry’s standards for tensile and tear performance with the introduction of StressPly® Max modified bitumen membrane.
The new StressPly Max membrane provides tensile strengths of 1,000 lbf./in. and an elongation of over 16 percent. With up to 170 mils (4,381 microns) of overall thickness, these membranes offer unmatched durability. Their highly polymerized composition ensures effective waterproofing with a combination of Styrene-Butadiene-Styrene (SBS), Styrene-Isoprene-Styrene (SIS) rubbers, and Kevlar® fibers, for long-term weathering performance.

Tom Bauer, Garland product manager, explains: “With Kevlar fibers and dual fiberglass/polyester reinforcement, this newest member of the StressPly family offers phenomenal strength and heat stability. In addition to all its life-extending attributes, StressPly Max incorporates post-consumer recycled tires in its roofing compound and recycled boiler slag in its surfacing, for increased sustainability.” According to Bauer, optional Starburst® mineral surfacing offers double the reflectivity of standard mineral surfacing, for an even higher level of environmentally responsible performance. These high-performance membranes also contain a fire retardant, which is added during the manufacturing process, ensuring that it will maintain its fire rating for the life of the membrane.
StressPly Max membranes, which can be hot or cold applied, are designed for use as the top component in built-up roof applications demanding superior strength. They may also be used to add extra durability in a two-ply flashing system or to repair splits, cracks, and other deteriorated areas in existing asphalt-based roofing systems.
