TPA Single Ply Roof System A Thermoplastic Tri-Polymer Alloy Single Ply Roof Membrane System
Dimensions: Thickness Roll Size
Composition: TPA Roof Membrane is a white thermoplastic single ply roof membrane which is comprised of an elas- tomeric tri-polymer alloy based on Elvaloy ® and blended with CPE and PVC. TPA Roof Membrane is reinforced with a high strength, wick resistant polyester fabric. TPA Roof Membrane contains a minimum 25% by weight of Preconsumer recycled content, which is blended into the black compound located below the reinforcing fabric. TPA Roof Membrane is asbestos free and exceeds the performance requirements of ASTM D 4434/D4434M-09, Type IV. Basic Uses: TPA Roof Membrane is an elastomeric membrane that accepts roof movement and thermal shock. It can be used in a vari- ety of single ply roof system configurations, such as mechanically attached, adhered and ballasted. TPA Roof Membrane is lapped and seamed using hot air heat welding equipment. TPA Roof Membrane can be used in situations where other roof systems are not practical due to weight or slope considerations. TPA Roof Membrane provides excellent resistance to fire expo- sure in a variety of roof system configurations. TPA Roof Membrane resists a wide range of harmful pollutants, such as acid-rain, falling jet fuel, and other minor industrial pollutants. It can resist exposure to oil, grease, dirt, and the detergents used to remove these contaminants. As an Energy Star Roof Star Roof Products Partner, Tremco Inc. has determined this product meets the Energy Star Roof Products Program guidelines for energy efficiency. Energy Star qualification is valid for Roofing products in the United States but not in Canada. Natural Resources Canada (NRCan) has implemented an Energy Star Program which currently does not include roofing products. A white TPA single ply roof system meets the requirements of California’s Title 24 Energy Efficiency Standards for Residential and Non-Residential Buildings and has been tested per the standards of the Cool Roof Rating Council. Limitations: •Positive drainage is required. •The bottom, black embossed underside of the TPA mem- brane is not intended for use as the exposed side. Packaging: TPA Roof Membrane is available in individual rolls or by the pallet, with 15 rolls/pallet. (10 rolls/pallet for 60 mil TPA) Membrane Color: White (black embossed underside). Custom colors such as gray and tan are available, but minimum order quantities are required.

Roof replacement usually involves more complexities than new construction roofing. Contingencies such as rusted or deteriorated decks, rotted wood components, rooftop equip- ment which cannot be moved or shut down, and numerous other conditions are often encountered. The following application information is designed to serve as a general guide. Your local Tremco Representative will prepare detailed specifications based on the condition of your roof. Structural Deck: Deck must be properly designed and struc- turally sound. Drainage: Ponding conditions will adversely affect performance of any roofing system. Where positive drainage does not exist, water removal from roof surface should be facilitated by lowering drains, and/or installing additional drains, tapered insulation, or an approved lightweight insulat- ing concrete slope system. Insulation: Insulation must be dry and kept dry. No more insulation shall be installed than can be covered in that day. Use of FAS-n-FREE ® Adhesive for solvent free, fastener free insulation attachment is the preferred method of securement unless otherwise specified. General Installation Procedures: According to job specifica- tions, prepare the surface to be covered: •Remove loose aggregate. •Replace areas of wet insulation, deteriorated deck and wood components. •Provide air seal at perimeter, curbs, and penetration flashings. •Attach new roof insulation according to job specifications. •Clean insulation surface of loose dust/debris. Membrane Placement: Plan the placement of TPA Roof Membrane to facilitate the fabrication of the least number of seams. Ensure that water flows over or along, but not against, the exposed edges.
