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.
