EnergyGuard™ Polyiso Insulation board is made of glass fiber-reinforced cellulosic felt facers bonded to a core of isocyanurate foam.
Benefits of EnergyGuard™ Polyiso Roof Insulation include:
Excellent “LTTR” value compared to any other FM Class 1 rated products of equivalent thickness.
FM approved, subject to the conditions of approval as a roof insulation when installed as shown in the current edition of the Factory Mutual Research Approvals Guide. FM Approved — consult RoofNav.com for specific assemblies.
Lighter than most other insulating products offering comparable thermal resistance; as much as five times lighter in weight than many other materials with the same R-value.
Excellent dimensional stability.
Lower overall perm rating than many conventional insulation boards.
High moisture resistance and no capillarity; is stable and maintains its physical and insulating characteristics.
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.
Refer to the application specifications in the current membrane manufacturer’s application and specifications manual for proper installation procedures.
