Radon Gas Ventilation

Radon guard is a patented structural under slab insulation and ventilation panel system that provides for radon gas removal insulation and a capillary break.
Radon gas ventilation. It starts out as uranium a heavy metal found in the ground and most rocks on the planet. Learn more about radon gas and why it is so dangerous. Radon guard is a sub slab depressurization panel that provides radon gas movement between the ground and the soil gas retarder to a vent pipe. An odorless gas radon is the result of the nuclear decay of naturally occurring uranium in the earth.
Asd systems vent radon gas by creating a vacuum in the soil below the foundation. Radon exhaust stacks placement to avoid freezing in cold climates. It s not a problem everywhere but the bedrock in some regions produces enough radon. 6 to 10 hours depending on complexity of running vent pipe from basement to roof.
Even though the radon pipe does not extend above the roof as close to the ridge as possible it discharges the radon gas in a safe way while reducing the vent height by 15 to 20 feet. It is however a noble gas with no chemical affinity but is easily influenced by air movements and pressure. When uranium decays it turns into. The intention of that design is to keep it far enough from open windows to prevent the radon gas from re entering the home but that is unnecessary and can work against you.
Radon stacks are often brought up through the walls and vented out through the roof like a plumbing stack. Radon is a radioactive gas and known to be a carcinogen. A active radon vent fan is installed to create a permanent and consistent negative pressure within the system. Run a 3 inch or 4 inch solid pvc schedule 40 pipe like the ones commonly used for plumbing vertically from the gravel layer stubbed up when the slab is poured through the house s conditioned space and roof to safely vent radon and other soil gases outside above the house.
In a house with forced air heating and cooling radon gas can easily be distributed throughout the entire dwelling. Schedule 40 pvc vent pipe using 3 in. Radon gas is approximately 7 5 times heavier than air. The best way to deal with radon gas is to suction it out of the lowest level and dump it outside or pressurize your lowest level so it never enters your home in the first place.
When installing an asd system for radon reduction any openings major cracks and penetrations in the building slab or membrane must be sealed. The radonaway rp145c radon fan is built to resist moisture and can be mounted inside or outside on a 3 in. In this example even though it does not technically adhere to the epa radon mitigation standards it does adhere to the heart of the safety issue. The negative pressure draws the radon gas to the suction point s where it is sucked through the radon system and vented to a safe elevation above the.
Radon is a radioactive gas you can t see feel taste or smell. Long term exposure to high levels of radon can cause lung cancer.
