Spray Foam - An Airtight Radon Protection System
Radon – the Silent Killer
Radon is a radioactive gas produced naturally when uranium breaks down in the bedrock, soil, and ground water. Although it’s not lethal as it permeates the air, prolonged exposure to radon gas can be harmful. Those who are exposed for a lengthy period of time have a 2%-5% lifetime risk of getting lung cancer. For those who smoke regularly, this risk increases to almost 20%.
- Radon is a radioactive gas that you cannot see, smell or taste
- Radon is the second leading cause of lung cancer
- Approximately 7% of homes in Canada have high levels of radon
How Radon Can Enter a Building
In every building structure, air pressure inside is measurably lower than air pressure in the ground soil outside. In a residential home, as air escapes, air and gas from the ground soil (including radon) seep into the interior.
Radon gas can enter a building structure through all types of openings – the foundation, exterior walls, support beams, wall joints, even floor drains.
When to Get Protection
Since 2010, new building codes require that more preventative measures be in place for homes. One method is the mandatory installation of a sub slab depressurization pump. If a home was built before 2010, the radon level can be tested by using a home kit. Health Canada recommends that actions be taken if the results are higher than 200 Bq/m³.

Spray Foam - Radon Remediation & Prevention
You’re not just adding insulation. You’re also adding radon protection. It is becoming common knowledge that spray foam is the superior choice for insulation. Spray foam also creates a continuous air barrier that acts as a first line of defence against radon and other gases. Plus, spray foam is a vapour barrier that protects the foundation. It is a building’s secret weapon for protection.
