Maintain healthy air in winter with effective ventilation

Why ventilation is crucial in winter to prevent humidity and mold in homes

In winter, when homes are often tightly sealed to retain heat, effective ventilation is essential to maintain a healthy environment and prevent moisture buildup. Moisture comes from many sources: everyday activities like cooking, showering, and even breathing. Without adequate air exchange, moisture can lead to mold, health problems, and structural damage.

The Dangers of Excessive Humidity in Winter

Moisture buildup promotes mold growth, which can worsen respiratory problems like asthma or allergies. It can also damage building materials, including causing wood to rot or interior finishes to deteriorate, while reducing the home's thermal insulation, which increases heating costs.

Solutions for good ventilation

Natural ventilation :

Ventilating daily for a few minutes is crucial, even in winter. Ideally, this is done in the morning or evening to renew the indoor air without excessively cooling the home.

Controlled mechanical ventilation (CMV):

This system ensures constant air renewal by extracting stale air and introducing fresh air. Double-flow CMV, in particular, recovers the heat from the outgoing air, thus reducing energy losses.

Dehumidifiers and maintenance of openings :

Additionally, dehumidifiers can be used for particularly humid areas, such as bathrooms and basements.

Recommendations

Investing in effective ventilation is essential to preserve indoor air quality and protect the home.

It is strongly recommended that you call upon a professional to diagnose the specific needs of your home and install a suitable system.

This not only helps reduce the risk of mold and damage, but also helps optimize the energy efficiency of the home.
