Key Benefits of Radon-Resistant Homes:

1. Effective and Affordable: Installing radon-resistant features during construction is simpler and more economical than retrofitting later. Builders can integrate these features using standard materials, ensuring hassle-free installation.
2. Energy Efficiency: Properly implemented radon-resistant techniques not only mitigate radon but also enhance energy efficiency. This dual benefit can lead to long-term savings on energy bills.

What Are Radon-Resistant Features?

Radon-resistant construction involves several key elements tailored to different foundation types:

• Gas-Permeable Layer: Positioned beneath the foundation, typically a 4-inch layer of clean gravel allows soil gases to move freely.
• Plastic Sheeting: Placed over the gas-permeable layer and beneath the slab, this sheeting prevents soil gases from entering the home.
• Sealing and Caulking: All foundation openings are sealed to minimize soil-gas penetration.
• Vent Pipe: A PVC pipe extends from beneath the foundation through the house to the roof, safely venting radon and other gases outside.
• Junction Boxes: Installed in strategic locations, these facilitate easy future upgrades, such as adding a vent fan if necessary.

Cost Considerations

The cost of incorporating passive radon-resistant features during new construction typically ranges from $350 to $500, with potential savings in high-radon areas. Upgrading to an active system with a vent fan, if required, adds about $300. In contrast, retrofitting an existing home can cost between $800 and $2,500.

Conclusion

Opting for a radon-resistant home during new construction is a proactive choice that enhances health and safety. By integrating these features early on, homeowners not only protect against radon but also enjoy potential energy savings.
