| StressPly Max modified bitumen membrane  Garland Canada 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 membranes provide tensile strengths of 1,000 lbf./in. and an elongation of over 16 percent. With over 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) and Styrene-Isoprene-Styrene (SIS) rubbers for long-term weathering performance.According to a 2004 survey on building service life in North America, the average lifespan of non-residential facilities is between 51.6 to 87.2 years, depending on their structural materials. Some studies have shown that over 70 percent of schools were built prior to 1969, of which 25 percent pre-date the baby-boom generation. In addition to such extended service live expectations, government buildings, particularly schools, are frequently subjected to high levels of rooftop traffic and abuse. Historically, such circumstances have made roofing materials with exceptional tensile and tear strength a popular choice for public agencies Charbel Boulos, general manager of Garland Canada, 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 Boulos, optional Starburst mineral surfacing offers double the reflectivity of standard mineral surfacing, for an even higher level of environmentally responsible performance 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. write your comments about the article :: © 2011 Construction News :: home page |
