Disposable Formwork for Ventilated Under-Floor Cavities 4 From 4

The water freezes and, increasing in volume, can lift the floor of the cold room, breaking it.

To avoid this problem, in addition to an insulating layer it is also common to lift the floor off the ground and ventilate it in order to keep the temperature of the cavity above zero and eliminate the humidity in the foundation.

To do so using natural ventilation, the under-floor cavity must be at least 20 cm high.

The traditional system involves creating under-floor cavities with a series of pipes through which suitably heated fluid (air or other) is conducted.

An increasingly important topic over the past years has been the excessive amount of energy used by buildings, a use that can be considerably reduced through an intelligent variation in how Iglu® can be used: roof ventilation.

By placing Iglu® formworks on the building’s horizontal roof, an air cavity is created that insulates from the heat in the summer and from the cold in the winter, resulting in savings in indoor air

conditioning.

Tests have been performed  on roof ventilation using Iglu®, in collaboration with the University of Malta.

which have provided very valid results.
