Benefits of using Heatlok HFO Pro for Radon Abatement

Heatlok HFO Pro has been tested for its resistance to radon gas by recognized independent laboratory tests that are comparing it to a 6 mil. polyethylene sheet (CAN-CGSB 51.34-M) for the abatement of radon gas. The results demonstrate that only 1.25” (32mm) of Heatlok HFO Pro is 65 times more resistant to radon migration than 6-mil polyethylene.

65 times more resistant to radon gas than a 6-mil polyethylene membrane (at 1.25”)
Can be sprayed directly on crushed stone due to high compression strength
Continuous insulation with no joints. Requires no sealant, tape or cutting of materials
Exceeds code by providing a 7.4/inch R-value under-slab surface
Tested in accordance with ASTM E2178 and K124/02/95 (method C of ISO/TS 11665-13)
ICC Compliant

Use Heatlok HFO Pro on Exterior Foundations

In new buildings, insulation is often installed from the interior. Yet the foundation can easily be accessed from the exterior and insulated on its cold side, below grade, before backfilling, which is the preferred method of insulating a below-grade foundation. Existing homes often have to be excavated to waterproof the foundation as a result of water infiltration. Heatlok HFO can be sprayed on the entire surface of the foundation and even cover the footing to create a slope towards the drain. Applying Heatlok HFO directly to the concrete, blocks or stone is recommended, depending on the type of foundation.
