How to Apply TPO T-Joint Cover

TPO T-Joint Covers are used to seal channels at splice intersections created by seam step-offs. Prefabricated T-Joint Covers provide a professional finished appearance and provide substantial labor savings compared to field-cut flashing.

1. Clean splice intersection area and T-Joint Cover with Weathered Membrane Cleaner.
2. Center T-Joint Cover over splice intersection.
3. Begin welding at the center point and work toward the outside. When welding TPO flashing accessories, initial temperature setting for heat welder should be 6 (on a scale of 1-10).
4. Check all welds with a seam probe once completely cooled (30 minutes).

Consult Spec Supplement T-01-11 for more information on temperature settings and equipment setup.
