Why windows sweat in winter and how to deal with it

Moisture that accumulates on the windows in winter destroys comfort and creates a favorable environment for the development of harmful microorganisms in the room. To solve the problem, you will need to approach the issue thoroughly and find out the cause of fogging before taking any action.

Reasons for fogging windows in winter

The appearance of a water film on windows from the street side is a natural phenomenon for modern double-glazed windows and wooden blocks. This is how the difference in air temperatures inside and outside the room manifests itself. The same factor speaks in favor of the high tightness of the window structure. Conversely, a build-up of condensation on the side of the room indicates a problem. The abundance of moisture on the glass, the joints of the PVC frame and the windowsill is the cause of dampness and a decrease in temperature, as well as a comfortable environment for the development of pathogenic bacteria and molds.

There are three reasons for fogging.

The abundance of condensation on plastic and wooden windows is favorable for the development of mold

Marriage

Despite its higher tightness than wood, PVC also expands and contracts with fluctuating temperatures. If the window is defective, this process will not pass without consequences for the material and the structure as a whole - the joints will disperse, air exchange will be disrupted, and condensation will begin to accumulate between the glasses. This problem cannot be solved by partial replacement - the PVC block must be completely replaced.

Poor installation

Incorrect installation of the window structure is accompanied by:

• the appearance of cracks;
• deformation of the seams of the window block;
• violation of the air circulation system.

Such shortcomings are solved under warranty, since the installation specialists made a mistake. However, to identify the reason, you will have to conduct an examination that will confirm or deny the fact of installing a window with violations of technical requirements.

High humidity

If the indoor humidity reaches 70-90%, in the winter it will lead to condensation settling on the glasses, since the temperature difference in the period up to 10-20 ^on C. The problem is exacerbated if the house is new - from the material continues isparayatsya moisture and concrete still shrinks. Poor sealing of floors, window joints with load-bearing walls, and a large number of indoor plants on window sills also contribute to an increase in humidity levels.

Elimination and prevention of glass fogging

The main task of dealing with "crying" windows is to reduce the level of humidity in the room. This can be achieved in several ways.

1. Ventilate regularly, especially in poorly ventilated areas.
2. Use a cooker hood. When cooking, a lot of hot steam rises into the air, which accumulates on the walls and windows.

3. Improve ventilation by reducing the width of the window sill and dismantling the solid screens near the batteries. These structures prevent the free circulation of warm air, which helps keep the glass dry.

   

   If you need to install a wide window sill, take care of additional ventilation, which is provided by special grills
4. In cold block houses, as well as in buildings located in low-temperature climatic zones, insulate the joints and slopes of PVC structures, seal them.
5. If the room is more than 20 m ², use additional heaters to heat and dry the air.

6. Do not forget to switch fasteners (pins) to the appropriate mode at PVC windows in winter.

   

   On plastic windows in winter, it is necessary to switch fasteners, which provide a tighter clamping of structural elements and help maintain the optimal temperature inside the room

7. Replace loose fittings.
8. Remove from the window most of the plants that require abundant watering.
9. Use light curtains made of materials that allow air to pass through.
10. Seal the joints of the load-bearing walls and floor throughout the room. This option is especially relevant for apartments on the ground floor in panel houses.
11. During repairs, give preference to a double-glazed window with heating or order the installation of a heating system.

In most cases, you can solve the problem of glass fogging on your own, but in the event of a manufacturing defect, you will have to spend money on new windows. If it is not possible to do this immediately, maintain the optimum temperature in the room by drying the air with heating devices and regular ventilation.
