About EnergyGuard™ Barrier Polyiso Insulation

- Lower overall perm rating than many conventional insulation boards
- Because of its light weight, this material is easier to handle on the job site and installs faster
- Easier cutting in the field provides the installer with simplified fabricating on the roof deck, which minimizes on-the-job damage
