Healthy indoor climate with solar heating
The indoor climate in well insulated modern houses is normally healthy for your fuel bill but certainly not always for your health. The problem stems from the missing air renewal.
Gone are the days of natural ventilation through numerous small leakages in our houses. Instead we find tight windows and doors, while walls and ceilings are sealed by vapor barriers. Moisture on the inside of the double glazing has become a sign of an unsound indoor climate.
Ventilation lags behind
Most new houses attempt to ensure a sound indoor
climate by ventilation through fresh air ducts.
However, the air renewal supply of many buildings has not been dimensioned to meet the actual needs of modern homes.
This causes a bad indoor climate, and in serious cases it may involve health risks because of dry rot in the walls and structure of the building.
Lumpy sugar and stale air in your cottage
Buildings left unused part of the year are particularly exposed to the problem of damaging air moisture content outside of the holiday season.
The indoor climate suffers from the relatively low temperatures and the closed windows and locked doors. Typical signs are stale air and lumps in the sugar bowl when the house is being used during weekends or opened for the season. |
