ZIP System® R-sheathing puts the "efficient" in energy-efficient, code-compliant walls. With multiple control layers built-in to an easy-to-install exterior sheathing system, ZIP System R-sheathing and tape is a streamlined way to meet 2015 IECC and IRC building envelope codes to manage air, water and thermal bridging. The newest innovation from Huber Engineered Woods LLC, ZIP System R-sheathing is an advanced engineered sheathing panel with an integrated water-resistive barrier that eliminates the need for housewrap, a continuous air barrier to manage air leaks and continuous polyisocyanurate continuous exterior insulation. Available in insulation thickness to meet all climate zone R-value needs, ZIP System R-sheathing is an efficient way to meet new codes or build high-performance thermal envelope wherever your build resides.
