The starting point of all ELEVATION® Waterproofing Systems. Made of 100% welded heavy gauge aluminum flashing for durability and long term exposure. TTP's eliminate the traditional method of relying on sealants and layers of membrane to seal the joint where the T-bar and Drip Edge flashing meet the building. In sharp contrast, TTP's require no sealant to complete the corner detail of the waterproofing system. While providing a leak free and simple flashing termination point, ELEVATION® TTP pockets are designed with a pitch to channel water entering the pocket away from the fascia.
