Why do plastic windows sweat in winter and what to do about it?
There are several reasons for glass fogging that do not depend on the quality of work on the manufacture and installation of windows:
The reason: Completing your window with a thin, single-chamber double-glazed window. Standard, without the use of energy-saving technologies, double-glazed windows are almost guaranteed to fog up in winter.
Solution: replacing the double-glazed window with a two- or three-chamber one. Attention! There is no need to replace the entire window, it is enough to change the double-glazed window.
Reason: The window sill located directly above the battery. This location makes it difficult for the circulation of warm air in the room, which leads to the aforementioned temperature difference and the appearance of condensation.
Solution: you can reduce the depth of the window sill, install an additional heater for the glass or move the battery to a greater distance from the wall. Replacement of the window sill.
The reason: The unfulfilled transfer of your windows to winter mode. Windows that work in summer mode have a lower degree of thermal insulation. The consequence is the low temperature of the inside of the double-glazed window.
Solution: to switch windows to winter mode.
The reason: There are plants on the windowsill that emit moisture.
Solution: Remove the plants to another place.
Reason: The room is not ventilated.
Decision: regardless of which windows you have installed, it is necessary to ventilate the room for at least ten minutes daily
