IN CASE OF WINDOW PANE CONDENSATE

 Condensate formation onto the surface interior to the premises of the double pane window and window frames.

In principle, a condensate could be formed onto the surface interior to the premises of the double pane windows, respectively window frames. This is also called steaming or fogging of the window. However, it should not be mistaken for the condensate formed on the inside of the double paned windows /when the condensate is located between the panes of glass, they are defective and you should ask the assistance of a specialized repair service/.

There is a constant release of water vapors in dwelling places. The following quantities could be taken as common ones:

- air exhaled by a single human being: 1 to 2 liters daily;

- cooking: up to 2 liters daily for a family of four;

- bathing, flower watering, washing etc.: up to 3 liters daily for a family of four.

The occurrence of the condensate starts from the window pane edge being the coldest part of the dwelling premises. Besides the wide sills, as well as the wing frame, could hamper the air flow so that the humidity at the lower edge of the window pane could occur earlier than that one in its middle part.

Condensate could be formed in unheated premises. The reason is the gradual cooling down of the premises at night and the total water vapor saturation of the air due to breathing when the temperature is relatively low.

Condensate could be formed not only onto the window panes but on every cold place in the premises. This leads to the occurrence of stains of fungi and mould on the walls.

The condensate could be considerably reduced and could disappear if definite rules are observed.

1.    The premises where condensate is formed should be aired more. This should not be performed by continuous airing /opening of a vent/.

2.    Airing with the window wide open saves energy and prevents from the occurrence of condensate and mould. The heating being switched off, the windows are to be open widely for 5 to 10 minutes so as the air saturated with water vapor to be replaced by new and colder one. This should be done three or four times a day.

3.   The north side rooms should be taken greater attention because they cool down quicker than the south ones in summer. It is advisable a temperature of 17-18 degrees to be maintained.

4. The least possible temperature variations should be maintained between the different parts of the premises.

5.   It is recommendable that the premises should be aired for at least 20 minutes in the morning. After opening the windows, a constant heating should be provided.

6.   Avoiding the condensate could be done by changing the flow of the warm air.

7.  Upon the lack of a heating appliance the situation turns into a condensate and mould formation favorable one.

8.  If it is possible heating not be alternately switched on and off but a relatively equal temperature during the whole day should be maintained.
