GreenGuard MAX Building Wrap is a cross-woven building wrap with a breathable polyolefin coating that performs as both a water-resistive barrier and as an air barrier in accordance with the International Building, Residential and Energy Codes. It is an excellent secondary weather barrier that helps deflect water and wind-driven rain, yet is designed to breathe to assist trapped moisture vapor to escape, helping walls dry faster. Kingspan GreenGuard MAX Building Wrap is non-perforated, providing superior resistance against the rain before the siding goes on and against water that seeps through the siding after installation. Kingspan GreenGuard MAX Building Wrap is UV resistant up to 6 months.
