The big disadvantage of this is that there is zero control over the amount of air, as the draft depends on the temperature difference between the air outside the home and the air inside the home. This leads to little draft in the summer and a lot of draft in the winter, which also leads to expensive energy costs for heating in winter.

Other types of home renovation without improving the type of ventilation can have negative consequences for your home. When replacing the heat source or replacing it with modern sealed windows, the natural ventilation can be changed as a consequence, and even worse circulation can occur. When renovating a home, we recommend that the ventilation is also examined.

It is possible to retrofit a balanced ventilation unit in all homes. To find the best solution for your home, simply contact us on 63 82 60 01.
