STORAGE When storing and handling Polyglass self-adhered membranes: • Store rolls upright on pallets in dry ventilated indoor areas; do not store rolls on their sides • Protect rolls from exposure to elements • Stage the project as products are needed BASIC INSTRUCTIONS: • Low-Slope self-adhered roof systems are primarily designed for roofs at 2/12 pitch or less. • When applying Polyglass ADESO Self-Adhered roof systems, ambient temperatures should be 40°F and rising. For temperatures between 25ºF-60ºF, use Polyglass Elastoflex SA V Polar Base and Elastoflex SA P Polar Cap – ADESO Self-Adhered membranes for cold weather application. • Do not install when water in any form exists. • All roof deck application areas must have positive drainage, continuous support, and be structurally sound to support all load requirements of the roofing system. • Prior to the application, be sure to properly prepare the substrate. • In re-roofing applications, be sure to remove existing materials and obsolete penetrations and repair any voids or imperfections in the substrate. Acceptable substrates include: • Polyisocyanurate insulation standard facer • DensDeck® Prime Roof Board or DuraGuard® Roof Board • Securock® Gypsum-Fiber Reinforced Roof Board • Primed concrete • Plywood sheathing with bond breaker tape at all joints • Polyglass Elastobase® Base Sheet • Polyglass Elastoflex SA V Base Sheet • Polyglass Elastoflex SA V PLUS Base Sheet Ensure installation of self-adhered plies do not prevent or interfere with ventilation of the existing structure. For more information, contact your Polyglass sales or technical representative. 5 Installation Guide Installing ADESO Self-Adhered Base Sheets: Prior to installation, allow the membranes to relax in the sun for a minimum of 15 minutes. • Ambient temperatures should be 40°F and rising when installing Polyglass self-adhered base sheets. For temperatures between 25ºF-60ºF, use Polyglass Elastoflex SA V Polar Base – ADESO Self-Adhered membranes for cold weather application. • Do not install when water in any form exists. • All roof deck application areas must have positive drainage, continuous support, and be structurally sound to support the dead load requirements of the roofing system. • Prior to installing self-adhered cap sheets, be sure the surface is clean of dirt and debris. • Start installation by cutting Elastoflex SA V base sheet to suitable lengths. • Lay the membrane flat and align the membrane at the lowest edge of the roof • Once Elastoflex SA V base sheet is in place, fold sheet in half to remove split release film at a 90 degree angle in a constant motion • After both sides of release film are removed, position the next Elastoflex SA V membrane by overlapping seams of the top sheet selvage edge a minimum of 6" • Press the membrane with firm and even pressure • Cut a 45 degree angle at the top corner of sheet, and at all build-up of joints such as T-joints and press next membrane at seam • Use hand roller at laps to ensure full adhesion • Once Elastoflex SA V membrane is installed, be sure to run 80 lb roller over the roof surface to ensure full adhesion 6 Installing Metal Edging: When installing metal edging, prime with either Polyglass PG 100 or other asphaltic primer that meets ASTM D41, WB 3000 primer, PolyBrite 745 or other commercially available water- based acrylic primer. 1. The roof flange of the edge metal should be 3" – 4" wide. 2. Install the roof flange of the edge metal over the base sheet strip-in at the lowest point on the roof. Nail the edge metal 4" on center in a staggered pattern. 3. Install Elastoflex SA V base sheet onto the edge metal leaving 1/2" of edge metal exposed at the eaves. Installing ADESO Self-Adhered Cap Sheet: Polyglass self-adhered cap sheets are available in SBS and APP formulas in eleven colors. See page 10 for full list of ADESO Self-Adhered Membranes. • Ambient temperatures should be 40°F and rising when installing Polyglass self-adhered cap sheets. For temperatures between 25ºF-60ºF, use Polyglass Elastoflex SA P Polar Cap – ADESO Self-Adhered membranes for cold weather application. • Do not install when water in any form exists. • All roof deck application areas must have positive drainage, continuous support, and be structurally sound to support the dead load requirements of the roofing system. • Prior to installing self-adhered cap sheets, be sure the surface is clean of dirt and debris. • Cut the self-adhered cap sheet to manageable lengths for the conditions and allow the cut sheets to relax prior to installation. • The cap sheet should be installed with the selvage edge away from the eaves edge. 7 Installation Guide Lay the membrane on the roof aligned with the eaves edge at the lowest point on the roof. • Once self-adhered cap sheet is in place, fold sheet in half to remove split release film at a 90 degree angle in a constant motion firmly holding the half of the sheet that is in contact with the roof in place as the liner is removed. • After both sides of release film are removed, position the next self-adhered cap sheet by overlapping seams of the top sheet selvage edge SEALLap ULTRA. • Do not remove the remaining release film covering the side lap selvage edge at this time • The end of each roll of ADESO Self-Adhered cap sheet has FASTLap; a granule-free end lap covered with a release film. Remove the FASTLap release film and press the overlapping sheet into place. • In cooler weather, it is recommended to hot air weld or apply modified asphalt flashing cement at all end lap seams. • Cut 45 degree angle at all build-up on seams and T-joints. 8 • Press each sheet into place with firm, even pressure. • Roll edges and all lap seams firmly with a hand roller to ensure full adhesion. • After each roll is completed, go over with an 80 pound roller with uniform pressure. Start at the center and work outward to remove trapped air. • For the succeeding sheet, position it by completely overlapping the SEALLap ULTRA, selvage edge of the previous sheet. • Only remove enough of the SEALLap ULTRA, selvage edge release film on the preceding roll to complete each section of the install. • When self-adhered cap sheets are installed, be sure to run 80 lb roller over roof surface to ensure full adhesion. • After 3 full thermal cycles, the roof system can provide a watertight, membrane system. 9 Installation Guide Do’s of Polyglass ADESO Self-Adhered roof systems: 1. Store rolls upright in packaging on pallets in dry ventilated indoor areas 2. Install material when ambient temperatures are 40°F degrees and rising. For temperatures between 25ºF-60ºF, use Polyglass Elastoflex SA V Polar Base and Elastoflex SA P Polar Cap – ADESO Self-Adhered membranes for cold weather application. 3. Only store and remove product from packaging on the same day of installation 4. Prime all concrete, masonry, metal or metallic surfaces 5. Prime all vertical surfaces 6. Apply to clean, dry, dust-free surfaces 7. Remove split release film at 90 degree angle 8. Roll all SEALLap ULTRA and FASTLap seams to ensure 100% adhesion 9. Reinforce all inside and outside corners 10. Lap granule to granule end laps at 6" 11. Heat weld or use SBS mastic at all laps and joints where adhesive compound laps onto granule surfaces. Don’ts of Polyglass ADESO Self-Adhered roof systems: 1. Don’t store material in direct sunlight 2. Don’t install during inclement weather 3. Don’t apply to dirty, wet or dusty substrate 4. Don’t apply directly to shingles or similar roof coverings How to transition from a low slope to steep slope: To ensure a watertight transition between the low slope system and the sloped roof, the Elastoflex SA V base sheet should extend at least 12" beyond the steep slope transition. The Polyglass self-adhered cap sheet should extend up the steep slope part of the roof a minimum of 18" beyond the transition point. Flashing of walls, roof terminations and penetrations can be done with the Polyglass self-adhered roof system. Begin installation of steep slope underlayment beginning 2" above slope transition.
