ventilate the house properly and keep the temperature as

constant as possible.

Forced drying: not too fast

Heating the house to promote the drying process is

sometimes called forced drying. Forced drying should

not be done too quickly, otherwise significant damage

(such as contraction cracks) can occur. It is therefore

recommended to give careful attention to forced drying.

Bear in mind that the forced drying process may take as

long as six months. Set the heating to 15 to 18°C, and

raise it to 20°C after moving in. Do not set the heating

any higher, as the materials will start drying too quickly

and damage to the building structure may occur.

Ventilation during forced drying

Good ventilation and air circulation are essential during

the drying process. During the first year, keep furniture

approximately 5 cm away from the walls to allow the

moisture to escape. Open the windows each day for

sustained periods. The ventilation grilles must remain

open all the times and the forced air ventilation system

should be left to run constantly (don't unplug it), Run the

forced air ventilation system at high speed as often as

possible during the first few months.

This will create the most favourable air circulation in the

house.

Energy costs

Good, continuous ventilation is not only important for

good health; it is also important to avoid moisture

problems in the house. However, ventilation takes heat

out of the house. Forced drying new houses also results

in higher energy consumption, resulting in a higher

energy costs.
