Modern renovation or construction of residentialpremises can not do without installing plastic windows. And this is justified, because at an affordable price opens a number of advantages: insulation, tightness, increased light opening and aesthetic look. But the joy of installing PVC products may not last long when there is such a problem in the winter as misting of plastic windows. The reasons for this state of affairs do not worry a person before the appearance of mold marks on the white slopes. And then the question arises: “What to do?”.
If we recall the basics of science, which describesthe laws of nature, it is possible to answer the question of why the plastic window is sweating from the inside. In the textbook for the 8th grade in physics there is a topic about the aggregative state of matter. Everything is clear: at various temperature indices, a substance can be in a gaseous, solid and liquid state. And a person observes this phenomenon daily, for example, when boiling water, when it begins to evaporate at 100 degrees.
The transition of a substance from a gaseous state toliquid is called condensation. This phenomenon occurs when the temperature drops. If you apply this knowledge to PVC windows, it becomes obvious reason why windows cry? The window itself is at the junction of two environments. In winter, it is cold outside and warm in the room. During this period, the surface of the glass inside the room has a lower temperature, so liquid vapors contained in the air begin to change the state of aggregation under the influence of temperature differences and settle on a cold plane in the form of droplets.
Wooden frames with glass that are not at allsealed, do not contribute to the appearance of condensation on the windows. You can, of course, leave the old wooden structures and not suffer from a wet window sill in the winter, but then the sums given to public utilities for heating the house will be much more impressive. After all, the beauty of PVC windows is in their tightness and preservation of heat energy at home.
In Soviet times, forced-air ventilationconsisted of ventilation ducts and slotted window frames, which carried out a constant circulation of air in the rooms. When people started to change window blocks for hermetic products, such an urgent problem arose as fogging of plastic windows. The causes and their elimination are interrelated: if the ventilation system is disturbed, it must be restored.
Another reason for water droplets to settle on windows is the humidity in the room. According to sanitary standards, this indicator for a normal microclimate should not exceed 45%.
If a hygrometer to measure the level of humidity in winterinside the living space, and it will show a value of 60% or higher, this will be one of the reasons why the plastic window is sweating from the inside. Dampness in the apartment appears when insufficient exhaust ventilation.
Steam is generated during cooking,washing, taking a shower. To avoid its concentration, it is necessary to adjust the work of the ventilation ducts, to air the room more often and to check the efficiency of heating appliances that should not be blocked by the sill by more than 1/3.
Запотевание пластиковых окон, причины которого They lie in the high humidity of the air in the dwelling, signaling an unfavorable microclimate, since dampness is an excellent environment for the development of mold and fungus. If you do not pay attention to the "weeping" windows, over time, the slopes will be covered with black spots, and this is a serious signal that you need to thoroughly engage in cleaning surfaces.
Harmless, at first glance, the human neighborhoodwith moldy walls turns into health problems. Invisible spores of the fungus and mold penetrate through the respiratory tract into the human body and impair its well-being. People with asthma are especially at risk. Therefore, the question of how to eliminate the fogging of plastic windows is not only relevant to maintaining the aesthetic look of the room, but also important for maintaining a healthy microclimate.
After finding out that condensate appears on thecold surface inside the room - the window glass, you will understand that if you reduce the thermal conductivity of the glass, the chances of the appearance of drops will be lower. Due to the thermal insulation of glass, you can increase the temperature of the inner side of the window.
Managers of window companies problem:“How to prevent condensation on the windows?”, They propose to solve by installing special double-glazed windows. A minimum two-chamber design should be selected, with energy-saving spraying and argon filling of the space between the panes.
It happens that after the installation of metal-plasticwindows, even premium-class, "crying" windows and slopes. This situation is due to the presence of "cold bridges". These are places that are simultaneously exposed to cold and heat. These bridges appear at the points of contact of the profile with the outer wall.
To avoid condensation near the windows, some calculations are performed by means of isotherms during the determination of the installation site. So, with a monolithic wall window unit is installed in the middle of the slope.
It is difficult for a man in the street to track the correct installation of the metal-plastic construction; therefore, the main thing when choosing a window company is to find professional installers.
Knowing the reasons why plastic windows are sweatingin the apartment, you can easily identify ways to solve the problem. It is important to ventilate the room in order to remove warm and moisture-saturated air. When you open the windows, especially in cold weather, the warm air from the room erodes, and the room becomes cool, but the humidity decreases. Enough short-term airing.
После принятия ванной или стирки рекомендуется include forced ventilation. And if there is none, you need to address the issue of its installation. In old apartment buildings exhaust channels are often clogged with construction waste. To test the ventilation, it is enough to bring a sheet of paper to it: if there is a draft, the sheet will cling to the grid, otherwise you should write a statement in the housing and utilities sector with a request to clean the clogged channel. That is, the hood must be present in the house, in places of high humidity: bathroom, toilet, kitchen, swimming pool (in a private house).
After sleeping, cooking, showering, washing andlarge crowds in one place need to air the room! And this will not only solve the problem: “How to get rid of the fogging of plastic windows?”, But also will create the right microclimate necessary for health.
Up to this point, the article explained the reasonscondensation and ways to prevent these "tears". What to do if not given proper attention to wet windows, and the situation acquired a neglected form - moldy slopes?
Fogging of plastic windows, the reasons for which are notso diverse, but require their identification, is the main source of mold. When the slopes are already covered with black spots, the detection of some factors of their formation is not enough, now you should get rid of the raid.
If this happened in the winter, it is provideddaily regular airing of the room. Slopes are treated with chlorine, alcohol solutions. With the onset of summer, it is necessary to dismantle the slopes: remove the affected areas of plaster. Then, after drying the repair site, you need to treat them with an antiseptic and waterproofing agent.
Required after antifungalprocedures should be thoroughly ventilated. When the effects of high humidity are removed, and the slopes are repaired, it is important to prevent the appearance of the "weeping" windows again. And, therefore, it is necessary to constantly air the room and use moisture absorbers.
