Halo® Subterra®

Perfectly Designed For Below Ground Applications

Subterra offers a high-performance GPS core that is laminated on both sides with a thick polypropylene film or an extra-tough cross-woven laminate (Subterra Plus).

Key Performance Advantages

waterproofing protection

Helps drain water away from foundation walls and protects waterproofing.

Energy Efficient

Continuous GPS insulation creates a thermal break and eliminates the energy loss from thermal bridging in the wall assembly.

flexible

Subterra is flexible and easily conforms to radius walls without needed time consuming field cuts.

Durable

Subterra Plus® is incredibly jobsite tough - it withstands severe foot and equipment traffic without breaking.

RAdon Barrier

Subterra Plus® is also approved to be a radon barrier and eliminates the need for an additional layer of poly.
