Kingspan GreenGuard® SuperStretch™ Butyl Flashing provides high performance water resistance for walls. It adheres across a full range of installation temperatures, ensuring effectiveness in all climates, and it conforms well to irregular surfaces, eliminating gaps that could create water canals. It stretches and sticks tight, making it easy to use and effective in covering curved surfaces and corners.
