Condensation on the plastic windows from the side of the room: the reasons and the solution of the problem. How to get rid of condensation on plastic windows

Many people, replacing the old windows with new plastic double-glazed windows, sometimes find condensation from the side of the room. This is an unpleasant phenomenon, requiring an early decision. After condensation on the plastic windows from the side of the room promotes the development of fungus and mold. The atmosphere in the room becomes unhealthy. Frequent airing in the winter period leads to large heat losses. Therefore, the problem must be solved in other ways. There are several recommendations that will help get rid of the condensation on the windows. To do this, it is necessary to determine the cause of this phenomenon.

What is condensate?

To understand how to get rid of the condensation on the windows, you need to understand the mechanism of its occurrence. Water settles on the glass when the temperature inside the room is higher than outside. In this case, the humidity in the room should be large enough to form a condensate.

The greater the distance between the outer and inner glass, the less often you have to deal with the problem of getting rid of the condensate on the plastic windows.

According to the sanitary norms, if the humidity in the room is within 30-45% and the air temperature is 20-22 ° C, the dew on the glasses will not drop out.

During construction, the dew point is calculated . She is outside the room, but at the slightest violation of the balance moves inside.

Why the dew point shifts

To prevent condensation on the plastic windows from the side of the room, engineers calculate all the conditions and parameters for the location of each element of the structure. However, over time, these indicators begin to gradually deviate from the norm.

Most often, to address the issue of the causes of condensation on plastic windows, you should pay attention to the thermal insulation of the room.

If the house was built not one decade ago, its walls were weathered under the influence of weather phenomena. Their insulating properties were violated.

If the interior layout was changed or the heating and ventilation systems, this could also cause the fogging of plastic windows.

As the research results show, the cause of dew on glasses is only 5% of cases, the fault of the manufacturer.

High humidity

Such a problem, like condensation on plastic windows (the reasons, the solution may be different), is determined by a specialist. However, it is quite realistic to try to understand the factors of dew formation independently.

One of them is high humidity. This will help determine the hygrometer. Sometimes, to remove condensate on the plastic window, it is enough to perform ventilation.

Also inside the room should be a good ventilation system. It is simply unacceptable to air an apartment in winter in severe frosts. There are also special desiccants. They will help to normalize the microclimate.

On sale there are valves that carry out constant ventilation of windows without loss of heat. And there are a lot of varieties of such systems.

Violation of the convection mode

To decide how to get rid of the condensate on the windows, you should consider the factor of disturbance of convection in the room. Even changes in the movement of air masses can cause fogging of windows.

Convection consists in raising the warm flow upward, and cold - lowering down. If the window were not located above the battery, it would freeze, collecting condensate on the glass.

If something prevents the battery from heating the space above it, this is already considered a violation in the convection process. Deciding how to get rid of condensation on plastic windows, you should pay attention to the sill. If it is too wide, the flow of warm air from the battery simply does not reach the windows.

Have to replace the sill, or make holes in its plane, so that the stream can move up.

Double-glazed windows

Too wide a double-glazed window very often leads to the formation of moisture from the side of the room. Strangely enough, if it is more than 70 cm, this will prevent other properties of the window. And in this case you will have to install a good air-conditioning system or change the window. That's why you should choose a normal profile.

The condensation on the windows and the freezing of the double-glazed windows can be caused by the type of construction. Single-chamber varieties of windows in severe frosts can even be covered with ice. This leads the hosts in horror. But this is the simple laws of physics.

If the window has two glasses, they freeze more strongly than in the two-chamber. In this case, the solution to the problem will also be the replacement of the window. It is better to initially purchase a double-glazed unit. Even if condensation is collected on them for some reason, it will not freeze. Three glasses give more chances that the windows will not fog.

Defect

It happens that the cause of the problem is the defect of one window. This is evident if all the rooms have the same double-glazed windows, but only one of them sweats. But to determine how to remove condensate on plastic windows, if this problem is present in all premises of the apartment, it will be difficult.

This reason for the appearance of dew is rare. But if still the source of the problem is this, you should contact the firm that installed the windows. Its representatives will inspect the double-glazed windows and, if necessary, will fix the malfunctions. But before calling the wizard, you need to exclude the possibility of other causes.

If the dew falls inside the double-glazed unit, this indicates a clear defect in the installation or assembly. Unfair producers today quite a lot.

Elimination of heat losses for disposal of condensate

If the house in which the owners live, old, it may have large heat losses. This shifts the dew point to the room. In this case, the insulation of the walls will help to get rid of the condensate problem. And much better, if these actions will be made from the outside of the wall.

If the apartment is cold, it can also be the answer to the question of why the plastic windows are fogging inside. The causes of problems can sometimes be found in the work of old radiators. It is recommended to clean the cast-iron batteries well and clean them. You can replace them with new ones, but steel and aluminum will be less durable, although they have more heat emission.

It is better to restore the old cast iron. In addition to existing heating, install an electric convector or floor heating. This will reduce condensation.

Improve ventilation

If the apartment is warm, you need to check the ventilation system. The channel grilles must be well cleaned. Sometimes, to understand how to get rid of condensation on plastic windows, you should look at the layout of the neighbors from the top. If they carried out repairs, the ventilation shaft could be simply immured by them.

If the hood functions, the channels are not clogged, you can install a forced fan. It will be on request of the owners to switch on and drain the moisture as needed. For example, in the process of cooking or taking a bath this is more urgent than at any other time.

If the street is not very cold, you can ventilate.

This will also help to restore the correct indoor climate. In any case, it is impossible to tolerate the formation of condensate. This will not only lead to rapid deterioration of windows, but will also have a poor effect on the health of the people living here.

Prevention

If plastic windows have been recently installed in a dwelling or planned in the near future, preventive measures should be taken. This will increase the likelihood that the condensate on the plastic windows from the side of the room will not be collected.

For this, it is necessary to establish the optimum thermal and ventilation mode. It should reduce the ingress of moisture inside the premises (fix the roof, check the pipes in the basement, eliminate other leaks).

If the house is old, it is necessary to insulate the walls from the outside. To keep a large number of plants on the windowsill is also unacceptable. When cooking and taking a bath should use forced ventilation.

If the radiators are not functioning properly, they should be cleaned or replaced. It is important to provide for the winter and off-season use of additional heaters.

Having found out how the condensate forms on the plastic windows from the side of the room, you can find a way to get rid of such a problem. In each specific case, a number of measures should be taken to promote the disappearance of dew from the panes. It is impossible to put up with the appearance of condensate. This will lead to health problems, as well as the rapid failure of windows. Choosing the right way, get rid of the condensate can quickly and efficiently.
