TPA Coated Metal.pdf

For Fabricating Perimeter and Penetration Flashings Compatible with TPA Membrane

TPA Coated Metal is manufactured from a flexible non-reinforced Tremco TPA (Tri-Polymer Alloy) membrane factory laminated to hot-dipped galvanized steel. The metal consists of 24 gauge (0.023” minimum) G90 hot dipped gal-vanized steel with a back wash coat of 0.0001” clear acrylic, laminated on one side with a 20 mil unreinforced TPA Membrane.

TPA Coated Metal is used to fabricate perimeter edge metal and flanged metal flashings for use with TPA Roof Systems. The factory lami-nated TPA Coating on the metal allows for a heat welded bond to be field fabricated between the TPA Coated Metal and TPA Single Ply Membrane.

General: Roof replacement usually involves more complexities than new construction roofing. Such contingencies as rusted or deteriorated decks, rotted wood components, rooftop equipment 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 upon your roofs conditions.

Structural Deck: Must be properly designed and structurally sound.

Drainage: Ponding conditions are unacceptable and will adversely affect the performance of any roofing system. Where positive drainage does not exist, water removal from roof surface must be facilitated by lowering drains, and/or installing additional drains or tapered insulation, or an approved lightweight insulating concrete slope system.

Installation Procedures: 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 the attachment area. Move nozzle at a steady speed, immediately applying pressure behind the air nozzle with a neoprene roller or weighted wheel to ensure positive contact of the heated TPA Coated Metal and the TPA roof mem-brane. Minimum width of welded lap shall be 2.0” (51

mm) when performing hand welds.

Field test heat welded laps to assure proper construction. Perform field test after lap area cools to ambient temperatures. Properly constructed heat welds will not separate at the lap interface when tested.
