 Why EnergyGuard™ PolyIso Insulated Sheathing?

EnergyGuard™ PolyIso Insulated Sheathing is the right choice for many different insulation applications.  Only insulating the cavity wall area leaves up to 25% of the wall area under insulated by studs, creating a thermal bridge. Using this versatile, light-weight product will provide a solution for that problem along with some added benefits. 


  • Provide Continuous Insulation:  Eliminate thermal bridging by covering the studs and add additional insulation to the rest of the wall.
  • Help Control Air & Vapor:  Help reduce air infiltration and act as a vapor retarder.
  • High Insulation Value:  Superior R-value compared to other products of equivalent thickness.
  • Versatile:  Can be used in a variety of applications including cavity walls, masonry walls, stud walls, exterior stucco, re-siding, and vaulted ceilings.
  • Reliable:  Meets the requirements of ASTM C1289 Type I, Class 1. Available in 16 PSI and 20 PSI compressive strengths.
  • Light weight:  Easy to handle on the job site and installs faster. Easier cutting in the field provides the installer with simplified fabricating on the job site.
  • Safer for the Environment:  Manufactured with EPA-compliant blowing agents containing no CFCs or HCFCs; has zero ozone depletion potential (ODP); and virtually no global warming potential (GWP).
