Mapeplan P T-Patches are factory-produced flashings made from 55 mil non-reinforced Elvaloy® KEE membrane. They are designed to seal membrane overlaps and transitions at
splice intersections, which are common stress points in single-ply systems. T-Patches provide a uniform, consistent layer of material that reinforces these areas and enhances long-term watertight performance. Installation is required on all Mapeplan PVC roof systems to ensure proper seam detailing and system integrity.
