This rendering shows how each component of the Engineered Transition Assembly works toward air- and water-barrier continuity. At the product level, the key to the Tremco ETA system is compatibility of materials. But at the design and construction level, the performance of this system is in the process, which includes quality assurance elements, custom review by Tremco of all wall assembly details, and performance testing of the air and water barriers.
Where do the manufacturers of all the components fit in? They just make and sell stuff and then all the building professionals get to work it out, right? Not always—and certainly not if Tremco has anything to say about it. Tremco has patented and commercialized its Proglaze Engineered Transition Assembly (ETA) System as an integrated whole of compatible sealants, membranes, primers, and flashings (all its own products) with both insulation and sheathings (other manufacturers').
But the system is not just about products; Tremco has done extensive research and development to ensure compatibility. The system involves comprehensive details, a quality assurance program, and a performance warranty on the air and water barriers in any building—a first for the industry.
