techniques make homes safer from radon
These construction techniques
help block radon from entering the home. The occupants
will benefit from lower radon levels in their new home.
It is easy to upgrade when
there is a need to increase the radon reduction.
If high radon levels are found,
the techniques allow for easy and inexpensive installation
of a fan for increased radon reduction in the home.
Every new home should be tested for radon by the homeowner
Materials and labor costs for
Radon-Resistant Techniques vs. Retrofitting an Existing
Home is $350 to $500 vs. $800 to $2,500 (a 128% to 400%
Some construction companies
successfully use this as a marketing advantage.
Improve the Home's Energy Efficiency
techniques provide an average of $65 per year in energy
savings for the homeowner.
There are five major parts to
the passive radon-resistant system:
- A layer of gas-permeable
material under the foundation (usually four inches
- Plastic sheeting over the gas-permeable
- Sealant and caulk on all openings
in the concrete foundation floor.
- A gas-tight three- or four-inch
vent pipe that runs from under the foundation through
the house to the roof.
- A roughed-in electrical junction
box for the future installation of a fan, if needed.
