TPA Unreinforced Flashing Membrane
For tying the roof drain to the reinforced TPA membrane.
The unreinforced, monolithic TPA Flashing Membrane is designed to tie the roof drain to the reinforced TPA field membrane. It can also be used to secure seams, penetrations and TPA metal overlaps that require an additional placement of TPA membrane over the top to enhance the TPA roof system's watertightness.
Made of 55 mil thick TPA unreinforced membrane, its roll dimensions are 24" x 30".
