The self-adhering properties of the built-up membranes provide the perfect alternative when traditional adhesives or propane torch techniques are not desirable. With the combination of these membranes, Polyglass offers one-of-a-kind built-up roofing system that features ADESO dual compound self-adhesive technology, split release backing film, and mineral granulated surface. ADESO Dual Compound Self-Adhesive membranes are tough when laid and shrink-free. Due to Polyglass’ U.S. patent-pending unique lapping system called SealLap and U.S. patented granule-free system called FastLap, membranes fit tightly and bond instantaneously to each other. ADESO dual compound self-adhesive membranes are easy to install, self-sealing around nails, rot proof, and available nationwide.For the Parkway, Durable Roofing used Elastoflex SAV base sheet and Elastoflex SAP granular cap sheet. These two products are manufactured with ADESO dual compound self-adhesive technology. The membranes comprise the latest in asphalt adhesive technology as well as substantial, proven weatherproof compounds, featuring mineral granule surfacing available in various colors.The Elastoflex SAP and SAV were applied on top of the existing roof. After cutting the old flashings, an approved one-inch isocyanurate insulation was mechanically fastened to the roof. The base sheet, the Elastoflex SAV, was installed on top of the insulation. The cap sheet, Elastoflex SAP, was then placed in a staggered pattern atop the base sheet.“I was impressed with the application speed of the product,” said Joe Richards, president of Durable Roofing, based in Midlothian, IL. “The project went smooth.” In fact, it was the largest ADESO project to date for Durable Roofing and they finished it in an astounding eight days in April 2003 with a crew of fifteen. “They applied the roofing materials very quickly,” confirmed Terry Boyer, property manager of Parkway Collection Mall. “We are very satisfied with the product and the installation.” Just because the project went smoothly, don’t think that there weren’t any challenges. As always, safety was a major concern, as well as the noise level. “Due to the ease of application, we didn’t interrupt deliveries, so the mall could keep functioning while the roofing membranes were being applied,” said Richards. “Dropping materials, knocking the ceiling tiles out, and being loud were major concerns that we had to consider while roofing the mall.”A major benefit of the Elastoflex SAP and Elastoflex SAV are that they avoid the use of hot tar and open flames, which are key contributors to on-the-job injuries. “The ADESO products were selected for this project because of the insurance costs that are associated with more dangerously-applied systems, such as hot tar, plus the benefits of cleanliness and speed of installation,” said Fernando Mesa, eastern & midwest sales director for Polyglass.ADESO dual compound membranes are manufactured utilizing glass fiber or polyester reinforcement, with a “true” APP or SBS modified bitumen compound on the top surface and an asphaltic self-adhesive compound on the bottom surface. The dual compound aspect offers excellent protection against the elements. “Even if it rained, the product would have withstood the elements,” said Ted Nickelson, president of Southeastern Roofing Sales, Polyglass’ eastern Florida sales rep company.
