Installation of Mechanically Attached System: •All field sheets incorporate 6” control lines for overlap and fastener placement. •Start at the low point of the roof and position a half-width (39'' or 991mm) roll of TPA Roof Membrane square with the roof edge. Avoid wrinkles. Reposition when necessary. •Mechanically attach underlying sheet at the lap to the struc- tural deck with fasteners and 2 3/8'' (60 mm) diameter barbed membrane plates spaced at 6'' (153 mm) on center (or as specified) down the entire lap with the disc centered 1-1/8'' (29 mm) from the sheet edge. •Overlap perimeter sheet at side lap: 4.5'' (114 mm) mini- mum. Overlap at end lap: 3” (76 mm) minimum. Overlap field sheet 6” (153 mm) minimum. •The minimum number of half- width rolls required at the peri meter is 2. Determine the perimeter width as described in Section 2.2 of Factory Mutual Loss Prevention Data Sheet 1-28. Consult your Tremco Representative for further information. •Install the required number of half-width perimeter rolls along the roof edges both parallel and perpendicular to the roll direction in the field of the roof. Overlap perimeter sheets in the corner areas with perimeter fastener rows installed through both membranes in both directions. Install a mini- mum 6 inch (150 mm) wide cover strip centered over the fastener rows. Installation of Ballasted System: •Mechanically attach or adhere the membrane in the perimeter areas, using the required number of half width rolls, as deter- mined. •Unless otherwise specified, minimum ballast coverage is 1000 lbs/SQ, using ASTM D 448-98, number 4, 3/4” to 1 1/2” (19mm to 28mm). Gravel ballast shall be smooth, water worn, with rounded edges and corners. •During installation of ballast, do not create piles on the roof deck. Membrane Seaming: •All surfaces must be clean and dry. •For heat welding, allow the hot air welder to warm up. Insert the nozzle tip of the hot air welder into seam area. Move nozzle at a steady speed along the seam area, immediately applying pressure behind the air nozzle with a Neoprene roller or weighted wheel to ensure positive contact of the heated TPA Roof Membrane lap. Minimum width of welded lap shall be 1.5” (38.1 mm) when using an automatic welder. Hand welds shall be a minimum 2”(51 mm) wide. •Field test heat welded laps to assure proper construction. Perform field test after lap area cools to ambient tempera- tures. Properly constructed laps will not separate at the lap interface when tested. Consult your Tremco representative for additional information. Perimeter/Projection Attachment: Provide mechanical attachment of roofing membrane at roof perimeter, walls, expansion joints, and all other projections. Follow the recom- mendations of Factory Mutual Loss Prevention Data Sheets 1- 28, 1-29, and 1-49. Precautions: Users must read container labels and Material Safety Data Sheets for health and safety precautions prior to use. Availability and Cost: Contact your local Tremco Roofing Representative for pricing and availability. For the name and number of your Representative, call the Roofing Division at 216/292-5000. Maintenance: Your local Tremco Roofing Representative can provide you with effective maintenance procedures which may vary, depending upon specific conditions. Periodic inspections, early repairs and preventative maintenance are all part of a sound roof program. The solar reflectance of this roofing product may decrease over time. Roofs should be properly examined at regular intervals and maintained or cleaned when necessary and appropriate to assure maximum reflectance.
