15/16″ 4′ x 8′ ZIP System R3.6 Insulation Sheathing


  • The front fights air and moisture. The back fights heat and cold. Together, they knock out the elements
  • The integrated structural sheathing system meets wall bracing requirements and contributes to shear wall assemblies. Plus, the engineered wood panel provides a nailable, easy-to-flash base
  • Polyisocyanurate rigid exterior insulation on the back of the structural panel reduces heat transfer to help keep homes consistently comfortable year-round
  • Sealed seams with advanced acrylic ZIP System tape and ZIP System liquid flash form a continuous air and water barrier that manages water and reduces air leaks for an energy-efficient exterior
