Humidity in the home: did you know?
The ambient air is charged with humidity. A presence that is necessary in all healthy homes. But if between 30% and 40% humidity is needed on average, being below or above is harmful. This is why today, the standards in new homes are strict in order to guarantee good ventilation of the air. But sometimes the simple presence of the inhabitants is enough to raise the humidity level of the house. For example, a family of 4 releases on average 12 liters of water into the air. This amount may increase depending on the activities. Households, showers, dishes, baths… sometimes increase the rate to 80%. Good ventilation will overcome this excess humidity.
Here are the steps to optimize ventilation in a healthy interior
- Take care of the joints of wet rooms by maintaining them regularly. - Do not obstruct the air vents. - Do not caulk the communication doors. 2 cm of day are necessary for air circulation. - Do not switch off the electric VMC.

Since the air cannot escape, the water collects. A glaring example: a very well insulated modern house takes almost 10 hours to renew its air, while an old or less insulated house takes about 1 hour. - Ventilate your home every day for at least 5 minutes, taking care to turn off your radiators and after all activities that have caused an overload of humidity such as a bath or cleaning. - Check the waterproofing barrier in your home. Anything that surrounds your home or comes into contact with moisture should be regularly maintained. Roofs, walls, cracks, masonry joints are to be checked. Frost, wind, sun or heavy rain can damage these often stressed surfaces. - Check the capillary rises. This phenomenon comes from poorly drained water which rises from the ground to the bottom of the walls. The capillary increases mainly concern the ground floors. They can be caused by a diversion of the water network, too steep terrain, poor drainage of rainwater ...
