Halo® Interra®
Perfectly Designed For Interior Applications
Interra offers a high-performance GPS core that is laminated on both sides with a reflective film.
Key Performance Advantages
built-in vapor barrier
Eliminates the need for poly.
Reflective
Can reflect heat back into the home or building (dead air space required)
Energy Efficient
Continuous GPS insulation creates a thermal break and eliminates the energy loss from thermal bridging in the wall assembly.
No Thermal Barrier Needed
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.
