GreenGuard® Butyl Flashing
One of the primary causes of water damage in walls is leakage around windows, doors, and other openings. Deflect this water with GreenGuard high-performance butyl flashings. Both straight GreenGuard Flashing and GreenGuard SuperStretch™ Flashing conform well to irregular surfaces, eliminating gaps that could create water canals. And they adhere across a full range of installation temperatures, ensuring effectiveness in all climates. Straight flashing offers long-lasting adhesion on wood, polystyrene sheathings, and building wraps. SuperStretch Flashing stretches in any direction and sticks tight, making it easy to use and effective in covering curved surfaces and corners. Application is peel and stick, with a split backer for added convenience.
