Classic Wrap

Classic Wrap header

Classic Wrap is the toughest residential wrap on the market. With its cross-woven fabric, it is virtually tear-proof, even during the stresses of installation and after it’s nailed to the wall. Classic Wrap provides a layer of air resistance to increase energy efficiency. Plus it acts as a water-resistive barrier that breathes, allowing moisture vapor to escape and reducing the potential for condensation buildup. The wrap’s translucent design enables quick and easy installation. It stays UV-stable up to 12 months. Classic Wrap was previously sold under the Amowrap name and meets the same specifications.
