What is Radon?
Radon is a colorless, odorless, radioactive gas and the second leading cause of lung cancer. It infiltrates homes through cracks in the foundation, floor slabs, and sump pumps, posing a serious health risk. The EPA and American Lung Association recommend testing for radon and taking preventive measures.
6 Steps to Build a Radon-Free Basement
- Install A Depressurization Pipe
- Install An Air Barrier – Using Heatlok HFO Pro
- Seal The Joints – Prevents humidity issues in basements.
- Seal All Openings – Heatlok HFO Pro seals openings and posts, leaving no room for error. The product seals and expands 30 times its initial volume in 5 seconds.
- Install Floor Drains – Radon can use water as a vehicle for infiltration
- Install A Sealed Lid on Sump Pumps – Sumps can communicate directly with the gravel. It is therefore important to use specifically designed sealed lids.
How Heatlok HFO Pro Prevents Radon Infiltration
Heatlok HFO Pro Closed-Cell Spray Foam provides a seamless air barrier that is 65 times more effective than traditional polyethylene membranes at stopping radon. Applied beneath the foundation slab and along basement walls, it prevents soil gases and moisture from entering your home while delivering superior insulation (R-9.25 at 1.25” thickness).
Benefits of Heatlok HFO Pro:
- Radon-Resistant – Creates an airtight seal under slabs and foundation walls.
- High Insulation Value – Reduces energy costs while exceeding building code requirements.
- Mold & Moisture Resistant – Prevents humidity issues in basements.
- Flood-Resistant – Can stay in place even after water exposure.
- Durable & Eco-Friendly – Made in the USA with 22% recycled and renewable content.
Radon Protection for New & Existing Homes
- New Construction: Apply Heatlok HFO Pro under the slab and along foundation walls for maximum protection.
- Renovations: Spray directly over existing slabs and walls before pouring a new slab to create a fully sealed barrier.
I could not be happier with the experience we have had with Upstate Spray Foam. When they were done they cleaned up great and exceeded every expectation!
