Product Overview

EnergyGuard Polyiso Insulated Sheathing is made of bilaminate (aluminum and kraft) facers bonded to a core of polyiso foam. EnergyGuard Polyiso Insulated Sheathing is suitable for use in both new and retrofit construction. EnergyGuard Polyiso Insulation Sheathing also helps reduce air infiltration and act as a vapor retarder.
  • EnergyGuard polyiso insulated sheathing is a great option for helping to reduce energy costs due to its high R-value per inch
  • Polyiso sheathing eliminates thermal bridging by covering the studs and adds additional insulation to the rest of the wall
  • Because of its light weight, this material is easy to handle on the job site and installs faster, providing the installer with simplified fabricating on site
  • Can be used for cavity, masonry and stud walls, exterior stucco, re-siding, and vaulted ceilings
  • ASTM C1289
  • R-value is shown as manufactured

A utility knife should be sufficient but because it is 1" you may have to run through it 2 times to score and snap, same as you would use for drywall.

Pieces were cut from the sheathing and used to install two window air conditioners. These pieces provided a more air-tight fitting and far better insulation than the parts that came with the air conditioners.

Just like the real thing-Because it is. Had to replace some siding on my home. Took off old, rotted pieces, needed some foam backing board before nailing up the new siding, Home D had plenty in stock. I got the 1" as that's what was on house to begin with. Perfect. Cuts w razor knife, easily. Nailed back up w roofing tacks. Looks like the original builders work(but better cuz it's new!)

Best value for my application. This material is really easy to work with. Since I’m only installing on my shed, the ease of installation is more important than anything else. Simply measuring and scoring is all that is necessary. I’m using normal duct tape to hold into place.
