      Why EnergyGuard Polyiso Insulation?

      EnergyGuard™ Polyiso is a flat board made of glass fiber-reinforced (GRF) cellulosic felt facers bonded to a core of polyisocyanurate foam. EnergyGuard™ Polyiso is widely used in commercial construction for new and retrofit applications and is compatible with a large variety of roofing systems. To prevent thermal bridging, we recommend installing two layers of EnergyGuard with joints staggered.
