Halo Interra products are rigid foam sheathing insulation made from GPS (graphite infused expanded polystyrene).
Halo Interra is coated with a reflective laminate on both sides of the rigid insulation.
Halo Interra acts as a vapor barrier while providing continous insulation. In addition, when a sealed air gap between the reflective laminate surface and covering is provided an additional boost in R-value is provided.
Features
Halo GPS (graphite polystyrene) delivers a longterm 5 per nominal inch (thermal performance claim based on a thickness of 1-1/16")
Continuous GPS insulation creates a thermal break
Built-in vapor barrier (when an appropriate air space is provided)
Reflective laminate reflects heat back into the home or building
Interra FR is now regionally available and is specially formulated to not require a thermal or ignition barrier (in the USA only) when installed on any interior wall surface
