Plastic windows "cry": what to do? Why do plastic windows "cry"? Causes of fogging of plastic windows in winter Plastic are crying.

Plastic windows are one of the most perfect and highest quality window designs. Possess huge functionality, incomparable positive properties and high performance. But all this is possible only if the exact installation technology is followed, when the entire installation process takes place in accordance with the requirements and standards.

Also the quality by and large also depends on the care of the window block. If these conditions are not met, then there is a risk of malfunction and one of the most common phenomena is the formation of condensate on the inside of the window pane, that is plastic windows cry.

Why does condensation form?

The reason why windows sweat is in the simplest physics course that each of us studied in school. The appearance of condensate drops is possible only under those conditions when two temperatures collide with a large difference in their values. This also requires the third and main condition, very high humidity in the apartment. The number of formations on the glass surface will depend on its degree.

The place where two temperatures collide is also called the dew point, and the plastic window must be quickly installed so that this boundary is outside the room. Usually this point is considered the middle of the window opening. In principle, incorrect installation is the most common cause of condensation.

How can you avoid this problem:

• Buy designs only from those manufacturers who have a good name and reputation. This will be the best guarantee of quality and durability.
• At the time of purchase, examine the design for integrity. Cracks, dents, incomprehensible holes and other defects can cause serious problems.

There are window blocks, which, in principle, are practically protected from the formation of condensate. Engineers were able to achieve this thanks to an innovation in the design of double-glazed windows. A special gas was added to the empty space between the panes, under slight pressure, and the entire system was sealed.

Condensation on the window

Also a fairly common reason why problems arise is the period of the year when the installation was made. It is generally accepted in society that best time for installation is the summer period, since it is possible to calmly open the room and work at positive temperatures much more comfortably.

The ideal conditions for installation are the lowest possible humidity outdoors and temperatures ranging from fifteen to twenty degrees Celsius. If these conditions are not met, then at high humidity and too low temperature, the mounting foam will lose its properties and will be applied poorly.

It is better to entrust the entire installation to specialists provided by manufacturers upon purchase. Since they know exactly the technology and have trained their hands to make high-quality and durable plastic windows that do not cry or sweat.

Dealing with a problem

The first check of a plastic window block begins after the appearance of the first significant cold weather, that is, in winter. If there were no problems in the first year, then most likely there won't be any. But if condensation begins to form and the windows sweat, then the first thing any user begins to refer to is a poor-quality design or poor installation.

In many cases, of course, this is true, but very often the cause is a badly disturbed indoor climate. In this case, with the window and its installation, everything can be in perfect order.

You have collected for you a small set of rules that will help you adjust the climatic conditions of your apartment or house:

• Regular and continuous ventilation. Ideally, you should leave the window open for a few hours every day, but with the cold raging outside, this is not possible. It will be enough to ventilate the room for ten to fifteen minutes, daily. Stoves and electric heaters also help to reduce humidity.
• Turn off the boiling kettle in a timely manner and cook food only with the pot closed. Very often windows cry and sweat for this very reason.
• It is contraindicated to do drying for things from the radiator, the fumes will settle on the plastic windows. Also, do not open the battery by throwing curtains on the windowsill, so you will prevent the penetration of warm air to the window glass.
• In a window sill that is too wide, several holes must be made to circulate warm air from the battery.
• If the window sill is too full of things or flowerpots, they should be removed for a while to give even more room for movement for warmth near the plastic window.
• There are specialized devices that dry the air. Their use would also be appropriate, but in this case, additional costs for the purchase will be required.

If you decide to redevelop the heating system, then the main radiators should be placed near the windows. If they are pushed too far, then the appearance of condensate will only intensify.

In houses where it is possible to heat with a stove, this problem is solved very easily and quickly. The stove contributes to very high-quality dehumidification and rapid heating of the air and is the most effective means.

How to monitor the installation and prevent hack

To avoid serious malfunctions during installation, it is better to follow how the masters produce it. Since unscrupulous people can also get caught, who will try to evade work and try to finish everything as soon as possible, thereby sacrificing quality.

What you should pay special attention to:

• Be sure the frame must recede from the walls.
• The ebb must be mounted exactly as required by the technology.
• The installation of the frame must be perfectly level.

As practice has shown, irresponsible and illiterate craftsmen are now quite a big problem. Employers are willing to pay less to unskilled installers who often hack, and sometimes do not understand at all how windows should be installed correctly.

Plastic window care

For example, adjusting the pressure for the required season will significantly improve the quality of the thermal insulation of a double-glazed window and may reduce the risk of occurrence. At the slightest manifestation of a problem, you should immediately figure out what is the cause and eliminate the malfunction as quickly as possible.

Such an unpleasant phenomenon as condensation on windows can appear regardless of the time of year under the influence of various factors. Metal-plastic or wooden products have served faithfully for many years, but one fine day, the residents of the apartment find puddles on the windowsill or see drops on the glass surface. The liquid first gradually accumulates, then begins to flow down or freezes, which spoils the appearance of the room, and also makes it difficult to see. To eliminate all causes of condensation, it is necessary to understand the mechanism of its occurrence.

It is known from the school course that when heated, ice turns into water, and when the temperature drops below zero, the opposite process is observed. This is what is called moisture condensation. Air at high temperature contains some volume of liquid in the form of vapour. On cooling, the situation begins to change. Air is not able to hold the same amount of liquid, because it decreases in volume, and moisture settles in places with the lowest temperature. Window glass is the coldest place in the house, as it borders on the street (where the thermometer readings can be much below zero), so condensation forms on it. At extremely low temperatures outside the window, it turns into frost.

It seems that the condensate is not dangerous, although this is a misconception. With the regular appearance of liquid, wetting of building structures is possible, followed by a weakening of the rigidity of the structure and the appearance of mold fungus. Obviously, it is necessary to answer the question as soon as possible why plastic windows sweat and stop the destructive physical process.

Reasons for condensation

One of the functions of wooden or plastic windows is to protect the premises from freezing. However, products do not always fulfill their intended purpose, as they are operated incorrectly. The following are common causes of condensation:

• a significant temperature difference inside and outside the house;
• increased humidity in the room;
• too wide window sill above the battery;
• poor ventilation (clogged);
• non-compliance with the operating modes of windows (some double-glazed windows have two modes - winter and summer);
• the room is rarely ventilated (or never);
• a window is incorrectly selected for a certain room;
• the presence of plants on the windowsills.

There is another group of reasons that contribute to the formation of moisture on the glass. We are talking about errors in the production of windows, as well as inaccuracies during the installation of double-glazed windows. These factors will be discussed in more detail below.

Self-elimination of the causes of condensation

When you wake up one morning, you find water stains on the windows or puddles on the windowsills. What to do if plastic windows sweat? The main goal is to normalize the microclimate of the room. The task includes the reduction of humidity and the maximum heating of the inner glass (when installing a two-chamber package). To do this, you will have to perform a number of actions.

The first step is to check the ventilation. The system is designed to remove moist air. When the ventilation is clogged, it accumulates inside and later settles on the windows. Perhaps a lot of dust, dirt has accumulated inside the air conditioning system; this hinders its normal operation. It is very easy to assess the degree of clogging - just bring a lit match or lighter to the outlet. If the fire goes out or fluctuates, the ventilation is good; otherwise, you will have to clean it.

Wide window sill above heating system prevents proper air circulation. The right warmth does not flow to the window, due to which, as it cools, water forms on it. There are two ways to fix the problem:

• try to reduce the window sill so that the flow of warm air from the battery goes to the window;
• if possible, push the heating radiator out from under the windowsill;
• find another way to heat the window.

The presence of plants on the windowsill also complicates the normal circulation of air masses. Green organisms abundantly replenish the air with moisture, which later causes windows to fog up. By removing the plants from the windowsill, you can eradicate another factor in the appearance of condensate.

Part of the double-glazed windows sold has two modes of operation - summer and winter. If the transition from one mode to another is not made in a timely manner, then over time the windows will “cry”, because inner side cools down a lot. Before the onset of cold weather (October or November), it is recommended to switch the structure to winter mode.

Especially often, moisture condensation on glass occurs inside the apartments of heat-loving people who rarely open even the windows. What to do to avoid fogging? Ventilate the house at least 15-20 minutes daily. This will ensure not only a good circulation of air masses, which prevents the formation of condensate, but also an influx of fresh air, which has a beneficial effect on breathing.

It is also quite possible to insulate the space around the window. It is advisable to work with drywall. This is very effective material in terms of thermal insulation properties. You need to insulate window slopes, a place under the windowsill, outer wall. The more reliable the drywall finish is, the less likely it is that condensation will occur. An increase in temperature in the house will lead to warming of the space near the window.

All these actions can be performed independently very quickly. However, it happens that all the above points are taken into account, but the window sweats from the inside as before. Then more serious factors influenced the appearance of condensate.

Errors associated with the production or installation of double-glazed windows

Although plastic window installers position themselves as professionals, even they sometimes make mistakes. Some oversights are made by the tenants of the apartment in which the packages are changed. This group of reasons for the appearance of condensate include:

• errors in the design or manufacture of windows;
• purchase of unsuitable double-glazed windows for a particular room;
• installation errors.

It is unlikely that the consumer will in any way affect the process of manufacturing double-glazed windows. Moreover, low-quality products should be immediately corrected or disposed of. However, it is up to the buyer to carefully choose good windows for his apartment.

If you plan to install the product inside rooms or on a loggia (rooms bordering cold outdoor air), you should opt for two-chamber models. Windows with one chamber are suitable, for example, for a kitchen that borders on a glazed loggia (after all, it does not require additional insulation). Sometimes, due to economy, the consumer relies on thin glasses (single-chamber), hoping that they will adequately protect from the cold and prevent condensation. But this is just a delusion, and then you don’t need to be surprised why plastic windows on the balcony or in the room are crying.

When plastic windows replace wooden ones, you should be prepared for a radical change in the ventilation regime. If PVC is a very hermetic material, which by definition increases the humidity inside the house, then the tree has cracks in the structure through which air exchange is performed well. Comparing the plastic and wooden sets of two-chamber windows, one difference will be obvious - the inner glass of the first has a lower temperature than the second. Therefore, it condenses more quickly.

Installation (construction) errors are divided into three categories:

• incorrect foaming of cracks;
• the emergence of a "cold bridge" - a zone of junction of plastic or wood to the side of the wall with a negative temperature;
• masonry blowing - occurs when horizontal or vertical joints between bricks are destroyed.

If the consumer wants to get a durable construction, he should follow each stage of the window installation work. Also, you do not need to order a wide window sill.

Features of condensation of wooden window frames

As mentioned earlier, the tree is much better pvc passes air; ceteris paribus, it is less prone to the formation of condensate. However, if they sweat wooden windows, to fix the problem, it is worth starting from how they were insulated.

In order to normalize the microclimate in a house where there are double-glazed windows made of wood, it is recommended to perform the following actions:

• Remove the sealing gum (if any) and mounting foam from the upper part of the frame, observe the condition of the glass. If condensation still forms, you will have to leave the window frame without the elements removed until it dries completely. In order to speed up the process, you can use blowing from a heat gun, a fan with warm air.
• Condensation may occur due to improper installation of heating radiators or their poor quality. Sometimes windows sweat and cry because the heating equipment is located far from them. Sooner or later, to eliminate condensate, you will have to move them closer to the double-glazed windows.
• Wood is more sensitive to air currents than plastic. Condensation occurs even because of such trifles as an open door to a room, a leaking kitchen faucet. It is necessary to avoid such ways of getting moisture into the air.
• Washed things drying on batteries also have a negative effect on windows.
• Thick curtains darken the room and also increase the chance of condensation.

It is worth noting that wooden window sets are more preferable than PVC, as they form less moisture on the glass due to the surface structure, which transmits and evenly distributes heat.

It is good if the consumer monitors the condition of double-glazed windows regularly, taking measures to stabilize the microclimate. When he neglects the recommendations, even the most reliable two-chamber windows cry in winter, as they do in other seasons of the year.

If you briefly list the main tips for eliminating condensate, you get the following list:

• periodically check the performance of the ventilation system;
• ventilate the room several times daily for 10-15 minutes;
• do not seek to save on single-chamber sets;
• follow the careful foaming of the joint between the frame and the wall, as well as other installation steps;
• avoid wide window sills, completely covering the battery;
• if the double-glazed window has several modes, change them based on the season;
• pay attention to the careful sealing of window slopes;
• maintain normal humidity at home (45-60%).

Following the recommendations above, it is very easy to eradicate condensation if the windows on the balcony, in the room or in the kitchen are sweating. Glasses that allow you to see the world around you must always be clean and beautiful. Make them so affordable for everyone.

Plastic windows do not require repair; during rain, water does not leak between the sashes; these structures make it easy to keep the glass clean.

But sometimes during the operation of windows, one significant minus appears. As soon as the air temperature outside drops, condensation drops begin to collect on the surface of the glass in the room and the windows cry. Because of this, there is an accumulation of liquid on the windowsill, the humidity in the room rises, and fungus and mold may appear on the slopes.

Why are the windows crying?

If the windows start to cry, and the glasses fog up, then this may indicate that the installation technology has been violated or the wrong design has been chosen. When installing, preference should be given to two-chamber and more double-glazed windows, which have a micro-ventilation system. A single-chamber double-glazed window due to the occurrence of a large temperature gradient will almost always lead to condensation on the window. It is equally important that the warranty on the structures extends over several years.

Therefore, when choosing plastic windows, you should focus on reliable manufacturer, such as Rehau. This company appeared in Germany in 1948 and today has 170 branches in 53 countries. Since 1995, it has been supplying its carbon fiber and windows to aerospace and automotive industries. Everyone knows the development of windshield and headlight washer systems, batteries for electric vehicles and various composite materials.

If you are confident in the quality installed window, then the cause of condensation is the increased humidity of the air in the room and the lack of ventilation. In addition, a hermetically sealed plastic window blocks the access of air, disrupting heat transfer.

Ventilation, air exchange and plastic windows

It is not surprising that when the window glass in the room fogs up, many begin to wonder why this did not happen with the wooden structures in the apartment. Maybe the problem is plastic? If wooden windows were as airtight as new plastic windows, then they would also be covered with condensate droplets. The slots ensured the flow of air into the apartment and the presence of good ventilation in the room.

In order for the draft that removes dirty air in the house to be good, an influx of fresh air from outside is needed. This inflow is provided by ventilation shafts. Over time, the shafts become clogged, and the air flow in the room, and hence the air exchange, noticeably weakens.

Usually in all old houses there is a problem with the condition of the pipes in the basement and ventilation, which causes high humidity. During repair work: plastering, wallpapering, whitewashing, when protection from drafts is necessary, the humidity in the room rises many times, which contributes to the appearance of condensate. This problem goes away after it becomes possible to constantly ventilate the room.

Condensation in a room is affected by many factors:

cooking that takes place daily;

drying laundry in the room;

taking a shower.

Therefore, ventilation in the kitchen and bathroom is especially important. Here, constantly high humidity is constantly observed, and this causes plastic windows to cry more often.

To quickly eliminate moisture, you can open plastic windows and arrange forced ventilation. To completely solve the problems, it is necessary to clean the ventilation shafts and adjust the draft. To establish normal ventilation, the window vents must be equipped with a check valve.

Heating problem

To prevent plastic windows in the room from fogging up, the batteries of the heat supply system must be powerful and located strictly under the opening. The temperature in the apartment should be more than 20 degrees. The battery should not be installed deep under the windowsill. This will make it difficult for hot air to enter the window and lead to a violation of the air exchange in the room. The vegetation that stands near the window, and the aquarium with fish near the glass, also become sources of moisture.

In addition, radiators should not be cluttered or hung with heavy curtains blocking air access.

Warm air from the batteries should freely enter the plastic windows.

Plastic windows cry in winter

In winter, the window glass temperature drops significantly and the difference between it and room temperature is significantly different. With strong window cooling, a dew point occurs, that is, the air near the window glass in the apartment can no longer absorb moisture and drops appear on the glass.

In addition, the higher the floor, the more the windows fog up. In this case, due to poor ventilation and lack of ventilation, warm and moisture-saturated air rises, instead of entering the street into the apartments of the upper floors.

How to deal with condensation?

To combat condensation, it is necessary to achieve a uniform distribution of humidity in the room. At the same time, it is desirable that the air temperature in the house be at least 20 degrees, and the humidity should not exceed 45%.

Other reasons why plastic windows cry should be eliminated. It is necessary to carry out airing in the house at least three times a day. In order to prevent freezing of slopes, it is better not to use the micro-ventilation method in winter. It is advisable to open the plastic windows completely. The ventilation time should be at least five to six minutes. At the same time, the temperature in the house does not drop much, and the moisture content in the apartment is minimized.

If plastic windows start to cry, you should:

increase ventilation time;

reduce the moisture content in the room;

replace curtains with lighter ones;

control that compliance optimum temperature air, which will remove the reasons for the increase in moisture in the house;

check and, if necessary, clean the ventilation shafts.

If the window continues to sweat, then seek help from a specialist. The expert will accurately determine and eliminate the cause of fogging. Then the view from the window will not be clouded by condensate droplets and the problem will disappear.

There are a number of reasons for the formation of condensation on plastic windows, but most often this phenomenon provokes increased humidity in the room.

The temperature on the surface of the window winter time accordingly, it decreases and often to a point that experts call the dew point - this is the temperature at which air, which has relative humidity and a certain initial temperature, is no longer able to absorb moisture.

Causes of condensation.

Certain factors also contribute to increased humidity. For example, if this is a kitchen, then moisture is always released during cooking, and indoor plants on the windowsill or an aquarium can contribute to this in rooms. In addition, the person himself releases about fifty grams of water per hour when breathing.

So, if you, having noticed that plastic windows are crying, do not know what to do with it, it will be useful to first understand and, if possible, eliminate the causes of condensation. In addition to the above, common cause Such a nuisance turns out to be faulty or improper ventilation in apartments, which is present in the bathroom, kitchen, toilet, that is, where the humidity is high. Over time, the hood may fail and not cope with its task, since it tends to become clogged with accumulated debris.

Condensation factors.

In addition, windows made of plastic are highly hermetic, which does not allow air from the street to penetrate into the room and this already leads to a sharp change in heat transfer. So, condensate forms on the cooled window glass exactly at the moment when the air that has stagnated in an unventilated room comes into contact with it.

This problem is especially noticeable and familiar more often than others to residents of the upper floors of houses, and this is also observed in rooms with increased activity of residents.

Another common reason for the formation of "tears" can be called heating. Batteries must be powerful and serviceable, otherwise there will be a low temperature in the room and insufficient heat transfer. It must be understood that heating radiators, in addition to giving off heat to the room, they heat the window opening, and therefore they should not be cluttered foreign objects so that air can flow freely, unhindered and in sufficient quantities to the window.

How to eliminate the causes of leaks?

So, if you don’t know what to do with it when you see plastic windows crying, then the following tips will come in handy.

The best way to counter this phenomenon is to achieve the distribution of temperature and humidity in a room with plastic windows as evenly as possible. Optimal, according to sanitary and hygienic standards, is considered to be a temperature of twenty degrees Celsius, and at the same time, humidity, being a relative value, should not exceed 45 percent.

Do not forget to ventilate the premises three times a day (at least) regularly, and in cold weather it is better to avoid micro-ventilation, instead it is better to open the window completely for 5-6 minutes.

This problem is not uncommon, therefore, ways to eliminate it have long been found, in any case, this requires the organization of forced ventilation, that is, somehow air exchange must be activated in the window niche.

The main ways to deal with the problem of leaking plastic windows.

This can be done in several ways, each of which is quite affordable. So, what to do with crying plastic windows, or rather, how to solve this problem, you can do the following:

The first method, which is also the simplest, involves the presence of a fan in the house. So, in addition to using it for its intended purpose, that is, in hot weather, you can go for a trick, namely, direct it at a minimum intensity to the window, because the window niche needs any air movement.

The second method is suitable for romantics, and it consists in installing several candles on the windowsill in severe frosts. They should burn slowly and at the same time be as close to the glass as possible. A candle is also useful for plants by creating for them carbon dioxide- a favorite "delicacy" of houseplants.

The next method can only be called advanced, and is suitable for those who like to try their hand at craftsmanship and bring witty technical ideas to life. We are talking about covection screens - these are wide plates designed to set the direction of warm air by redirecting it to the window niche from the radiator. Such a plate is attached to the window sill at an angle of 30-60 degrees, as a result of which, warm air will be partially directed towards the glass.

But that's not all in deciding what to do, plastic windows are crying.

Another method involves certain costs, in particular, it is necessary to purchase any aerosol marked "anti-fog". You can buy it in a car cosmetics store, where you will be offered a wide selection. Remember that it doesn't have to be an expensive aerosol. Such "cosmetics" are used by drivers for the treatment of automotive glass. Thus, you will succeed, albeit a little and not for long, but still temporarily reduce the dew point of the glass.

The downside is that this is only a mitigation of the problem, not a solution to it, in addition, these aerosols contain a lot of chemicals and compounds, and their price may surprise you unpleasantly.

And the last way I wanted to talk about is the exotic way. Here you need foil or film (conductive, thin). A small voltage must be applied to it, approximately 12-24 volts, and then the window pasted over with such a film or foil will warm up, and the heat will mainly fall on the part most prone to freezing. Thus, you get a kind of electrically heated glass, like in cars.

Conclusion.

In conclusion, summarizing all of the above, we can conclude that in order to get an answer to the question: - what to do, plastic windows are crying so that this does not become a problem for a long time, the answer follows that you need to constantly monitor the humidity in the room. However, first of all, it is important to carefully monitor that even when installing the window, all requirements and norms are observed, moreover, a lot depends on the quality of the structure itself, and only then on the conditions in which it will serve.

The hot time has come for the installation of plastic windows. Warm spring weather prompts to shell out for replacement windows. And window companies have already started the new season.

The past cold weather reminded us that reliable plastic window systems promise not only warmth, but also serious savings in electricity that has risen in price.

However, not everywhere they cope with the peculiarities of plastic windows. In winter, plastic windows cry in some apartments - poor ventilation worsened the microclimate in a room with sealed structures.

And there are doubts whether to order PVC windows, despite the fact that they are the most affordable today.

According to experts, in 99% of cases, plastic windows “cry”, because after their installation, the room turns into a hermetically sealed “jar”, ​​where there is no ventilation that allows fresh air get into the room, and the spent one - to leave it.

In addition, water vapor emitted by residents and indoor plants, as well as being a consequence of household activities.

All this has little to do with the quality of window systems. Objective factors are of great importance. Compared to Western countries, the plastic window market is going through a teenage period. And, accordingly, suffers from "childhood diseases." There are Russian features - a different structure of the walls, the architectural specifics of buildings, other building technologies.

But the most important thing is the climate. Even in the capital, in the Moscow region or in the central regions, where the weather is milder than in the northern and eastern regions of the country, Euro-windows fog up, condensate drips form on them, and puddles form on the window sills.

What is the way out so that plastic windows in Korolev, in Kazan, in Siberia and beyond are everywhere like in Europe? Experienced companies adapt technologies and adapt popular window systems to our conditions.

Technical causes of fogging windows

Identified several errors in the installation associated with the "dew point", because of which the windows "cry".

• The profiles are too close to the walls. It is necessary to make a small gap, insert wedges between the frame and brick or concrete wall. The gap is filled mounting foam and get an additional thermal insulation layer. A cold stone surface will not cause condensation.

• If the ebb is incorrectly fixed, then cold and wind will penetrate under it. The lower part of the window will freeze, and a “dew point” will form on the outer surface of the glass. This is due to the temperature difference with opposite signs. The ebb must be fixed properly, and the free space must be filled with foam.

• A "dew point" can form when the plastic structure is not properly leveled. The slightest deviation from the horizontal position will lead to loose, not according to technology, closing of the valves. And the appearance of the "dew point" is inevitable.

Visualizing the "dew point" is easy - one has only to remember the frosty patterns on old windows. And how they laid double frames with cotton wool or paper. Excess moisture was absorbed into the cotton wool, and a draft walked in the cracks of the slopes, heating the street.

This old-fashioned method has been replaced by a hermetic and lightweight design. It remains only to learn how to properly install it.

Often the reason for the formation of condensate is impaired ventilation, when the exhaust system does not cope with its function. By the way, checking this is quite simple - just open the sash of any window and attach a sheet of paper to the hood hole in one of their rooms. If the air flow presses it against the decorative grille, then the ventilation is working properly, if not, an additional exhaust system channel is required.

Often, fogging of double-glazed windows and their subsequent “crying” is caused by high humidity in room. Moreover, as a rule, this is not typical for the entire living space, but precisely for that part of it where the greatest evaporation occurs. This is a kitchen - with a working kettle and a stove on which food is cooked, and insulated balconies and loggias where linen is dried and numerous plants delight the eye.

What to do so that plastic windows do not cry

You can get rid of excess moisture in various ways:

1. - with a dryer
2. regular ventilation,
3. use of the hood, g
4. good housekeeping and
5. rational use of household appliances.

So, for example, when turning a glazed loggia into a “winter garden”, be prepared for the fact that in the absence of air circulation you will encounter the so-called “greenhouse effect” and, as a result, foggy and “weeping” windows.

In case of disturbed air exchange, the insulated glazed balcony, on which the laundry is dried, will also turn into a mini-sauna. To avoid this, it is enough just to put the shutters on the ventilation mode and ensure full air circulation in the room.
