GreenGuard® HPW™

Kingspan GreenGuard® HPW™ Building Wrap is a non-woven, non-perforated building wrap. Its breathable polyolefin coating performs as both a water-resistive barrier and as an air barrier. HPW™ provides superior resistance against the rain before the siding goes on and against water that seeps through the siding after installation. Stays UV-resistant up to 6 months and can be used in residential and commercial applications.
