ZIP System stretch tape is a high performance, extendable self adhered flashing material that locks out air and moisture over a wide range of building substrates and mismatched surfaces. This code-recognized flashing tape stretches and forms around irregular and difficult to seal areas like rough openings, curved window heads, wall and roof penetrations. The strong, yet stretchable, acrylic foam core allows for continuous, single-piece flashing without having to piece tape segments together. It is UV resistant, and unlike most other flashing tapes, ZIP System stretch tape is compatible with flexible PVC windows. Like all pressure sensitive adhesives, manufacturer recommends rolling the tape with a J-roller to ensure proper installation. Passes testing per AAMA 711-13.
