Flashing

The HomebrellaTM Flashing System offers outstanding moisture protection, and provides the ultimate line of defense around windows and doors. The Homebrella™ Flashing System uses Contour® Stretchable flashing in conjunction with OptiFlash® premium butyl rubber flashing, which when installed according to specifications shown in the Flashing System Installation Guide, will provide a superior weatherproof seal for all window, door and skylight installations.

Studies show that inadequate design and construction of flashings are responsible for a high percentage of window and door leaks. Poor design detail is one of the most common causes of building envelope defects and builder callbacks. When installed properly, OptiFlash and Contour can intercept and direct the flow of water to designed drainage paths to prevent water from penetrating the building. Both Contour and OptiFlash have self-sealing properties that can stop leaks around fasteners that may later be driven through the adhesive. Consider the benefits…
