Disposable Formwork for Ventilated Under-Floor Cavities 2 From 4

Radon gas Radon is an odorless and colorless radioactive gas generated by a few terrestrial rocks caused by decay of uranium 238 and is able to emerge on he surface also at a distance very far from its origin.

It easily info literates through cracks in the bottom levels of buildings: basements, cellars, etc.

Andre presents a risk to our health.

As it is a radioactive gas, Radon can be carcinogenic if inhaled. As it is mainly released from the ground, if it is not dispersed outside it accumulates in

closed rooms where it becomes dangerous.

It is considered the second cause of lung tumors after smoking…Our country and some areas in particular have large amounts of Radon and therefore there is the need for constructive solutions that account for the elimination of this radioactive gas.

The final solution

A ventilated under-floor cavity created with IgIu represents an effective, quick and economic solution that makes it possible to send humidity and dangerous Radon gas to the atmosphere, which is beneficial to our health.

The air cavity formed by the Iglu modules must be connected to the outside with simple pipes.

This creates a natural air flow that crosses the cavity and eliminates moisture and Radon gas (if present).

The results of some ventilation tests (carried out on our behalf by the University of Brno – Czech Republic – available on request) indicate that the factor that has the greatest impact on the passage of air below the under-floor cavity is the presence of wind and its direction.

The form of the Iglu was designed to create minimum air resistance in the soffit of the modules.
