With a multitude of eco-friendly features, StressPly Legacy membranes set a new standard for sustainability in modified asphalt technology. StressPly Legacy FR Mineral incorporates smog-reducing granules to significantly reduce smog, while StressPly Legacy utilizes 100% recycled boiler slag. These modified membranes are composed of repurposed polymers that divert materials away from landfills and make use of post-industrial recycled streams: Styrene-Butadiene-Styrene (SBS), plastics, crumb rubber from tires, and recycled mineral fillers. The compound consists of 6 different environmentally conscious raw materials, including a high-strength and puncture-resistant reinforcement that contains yarns from recycled plastic bottles. With absolutely no sacrifice in quality, StressPly Legacy membranes maintain Garland’s high performance roofing systems while benefiting the environment.

Method | Description |
---|---|
Hot-Applied | StressPly Legacy membranes can be used with ASTM D 312, Type III or IV asphalt, Garland’s HPR All-Temp Asphalt or modified asphalt. One or two plies of ASTM D 2178, Type IV or VI fiberglass felt, or one layer of a Garland modified base sheet, are solidly bonded to the approved substrate. The StressPly Legacy membrane is then solidly bonded to these base layers with mopping asphalt. |
Cold-Applied | StressPly Legacy membranes can also be applied in Garland’s cold-applied Weatherking® and Green-Lock® Plus membrane adhesive. One or two layers of Garland approved base sheets are applied in Weatherking or Green-Lock Plus membrane adhesive to the approved substrate. The StressPly Legacy membrane is then adhered to these base layers with Weatherking or Green-Lock membrane adhesive. |

Benefits | StressPly Legacy Features & Benefits |
StressPly Legacy FR Mineral includes unique smog-reducing granules in its mineral surface. These granules are formulated to bond with pollutants in the air surrounding a building. A typical 20,000 square-foot commercial roof has the smog-reducing benefit up to 216 trees.
Each roll of StressPly Legacy contains the recycled plastic from an estimated 20 recycled bottles in its reinforcing scrim. Each batch of StressPly Legacy has enough crumb rubber in its formulation to keep 8 tires out of landfills. And, StressPly Legacy includes 4% bio-based content.
Every aspect of StressPly Legacy has been considered for environmental impact. The packaging is biodegradable. The product ships to the job site carbon-neutral thanks to transportation carbon offsets. And most importantly, the product is engineered to last, with a 30-year warranty for StressPly Legacy FR Mineral.
