    A couple of years ago, new windows were installed in the house, and now there is strong condensation. Why is this happening?

      If condensation occurs immediately after the installation of windows, then the reason may be the wrong choice of glass unit. In residential premises, it is better to install 3-chamber double-glazed windows, and leave inexpensive 2-chamber windows for cold balconies and loggias.
      If condensation occurs in the very first winter, then it is likely that everyday mistakes were made when installing the window. For example, there are gaps between the wall and the frame. Penetrating there, the cold street air provokes fogging of the windows. Poor-quality fittings may also be the reason, due to which the sashes do not fit tightly to the frame.
      If the problem occurs in the second or third year after the installation of windows, then first of all, the fittings are revised (it may need to be adjusted) and the rubber seal on the windows (it could have worn out).
      To prevent the appearance of condensation, plastic windows require regular maintenance. The moving parts of the fittings are lubricated, the screws are adjusted if necessary, and the sealant is lubricated twice a year (in autumn and spring) with universal silicone greases or compounds that soften the rubber and extend its service life. The worn-out seal is changed.
      Sometimes the reason for the formation of condensation is the wrong installation of the window sill, blackout curtains or insufficient heating. Try to keep the warm air from the radiator to the glass unobstructed, and you may be able to get rid of wet drops on the glass with minimal effort.

    Three main factors affect the formation of condensation on windows:

    - cold air outside:
    - high humidity in the room;
    - double glazing with poor thermal insulation.
    Also, the accumulation of condensate on the windows can be the result of improper installation of radiators (radiators). If they are located away from windows, completely get rid of the "window crying" will not work.
    The absence of exhaust or clogging, and consequently, poor ventilation of the room.
    How to fix the problem
    1. The first thing you need to check the hood and if there is a blockage to clean the channels. If there is no hood, air the room regularly.
    2. If there are pots with flowers on the windowsills, they should be removed, as the plants also emit moisture.
    3. A fan heater installed on the windowsill or a heater placed near the window will help to dry the “tears” on the windows.

    By the way
    Here are some popular ways to combat condensate.
    Place a lighted thick decorative candle on the windowsill.
    At least once a week, wipe the glass with a rag dipped in vinegar.
    You can wipe the windows with a solution of medical glycerin and pure alcohol (proportion of 1: 20). This procedure should be performed once per 15 days.

    We have an unheated kitchen in the house, which we warm up only during severe frosts, so that there would be a small temperature plus. Nevertheless, the windows in this room are constantly wet, and the walls are moldy. How to avoid this?

      Your case perfectly illustrates the indisputable laws of physics, which are already described in the school course: when steam from a boiling kettle settles on the wall and dew “runs” along it. In the same way, water vapor, which is inevitably present in the air of your home and in a heated kitchen, immediately settles on cold windows and walls. Moisture from them condenses in the form of dewdrops, while the wall is saturated with moisture (which it does not really need, but ultimately harms). This happens regardless of what material the wall is made of. There is no miracle to be expected. Either you will not heat the kitchen at all, or you will have to conscientiously warm the room. And outside. In addition, ventilation should be arranged. It will help to carry away air with water vapor, then moisture will not settle on windows or walls. But the price for this issue is the idle heated air that goes into the ventilation system, simultaneously cooling your kitchen. But there’s nothing to choose from.
