Plastic windows in a wooden house are crying. Why do plastic windows sweat in winter, leak and cry in a private brick and wooden house, apartment, balcony, loggia, new building: reasons. What to do when condensation forms on plastic windows and they...

If plastic windows are correctly selected, there are no questions about their heat and sound insulation, but the formation of condensation can become a problem.
Fogging of glass is not just an annoying nuisance, it can seriously affect the microclimate of the room and lead to negative consequences(fungus, mold, destruction of building and finishing materials, harm to health). Let's figure out why plastic windows cry and how to solve this problem.

Why plastic windows sweat: 6 typical reasons

There is always some water in the air. While she is in gaseous state, no problem. But if the temperature drops to the dew point, moisture settles in the form of droplets on surfaces. Accumulating on the glass, it forms a translucent film and gradually flows down onto the windowsill.
The main reasons for fogging of plastic windows:

It happens that even high-quality ones that are perfectly installed in rooms with an ideal ventilation system fog up. The reason may be trivial: an excess of flowers on the windowsills. If plants evaporate too much moisture, condensation will occur no matter what the home owner does.

The solution to the problem is simple: you should move the flower pots to another place for the winter. They can be near windows, but not on window sills.

Why condensation on plastic windows is a dangerous phenomenon


If plastic windows cry, it's serious problem. And it's not just the deterioration of foggy glass. Due to condensation, windows freeze and frost appears on them. Moisture destroys the mounting foam that fills the joints between structures. This leads to deterioration of thermal insulation and protective properties windows

When condensation forms on windows , the house becomes damp. Appears quite quickly bad smell, fungus. Microorganisms multiply at tremendous speed and infect Decoration Materials, furniture, textiles. The walls become covered with dark spots, wallpaper and plaster peel off, and the house begins to resemble a damp basement.

All this is not only unaesthetic, but also dangerous to human health. The spores released by the fungus infect respiratory system, provoke asthma, serious allergic reactions, reduce resistance to diseases. It especially suffers.

How to eliminate condensation: 6 ways to solve the problem


First, you need to determine what caused the windows to fog up, and then solve the problem. The methods are simple:
  1. Leaky windows. Check the tightness of the closed doors: bring a lit match to the door. If the fire burns evenly, everything is fine. If it fluctuates, you need to adjust the sash. It should be aligned vertically by tightening the bolts on the hinges.
  2. Poor glass heating. If warm air from the radiators does not reach the glass, carefully drill several holes along the length of the window sill. The problem may also arise due to battery-powered screens. They just need to be removed.
  3. Violations of slope finishing technology. In this case, installers are required to redo the work.
  4. Worn seal. Examine it. If you see that there are places where the material is folded or cracked, contact the company that manufactured the windows to ask about replacing the seal.
  5. Poor ventilation. If it is not possible to alter the ventilation system, be sure to ventilate the premises. Or use a simple but effective mechanism - supply valve(popularly known as a window ventilator).
  6. Excessive humidity. Hardware stores have special desiccant absorbers. Buy one of these devices for each window.
There are cases when condensation on windows is a temporary phenomenon that is not worth worrying about. If you have recently made repairs that involve wet cycles (plastering walls, wallpapering, etc.), the treated surfaces will evaporate moisture for several more days, or even weeks.

Here you can only put up with the fogging of the windows and wait until the finish dries completely. Dehumidifiers will improve the situation a little.

Taking into account the above and in order to avoid problems with condensation on windows in advance, call a surveyor from the Vega Plast company. After receiving qualified consultation For window installation, feel free to place an order. And everything will be fine with you.

When buying and installing plastic windows, every owner hopes that now the topic of breakdowns can never be raised again. As they say, set it and forget it. And what a great disappointment for all residents when, with the arrival of winter, droplets of water begin to appear on the windows. We want to reassure you right away - this is far from the worst thing that could happen. However, there is still a problem, and it needs to be solved.

Why does moisture appear on the surface of glass, and how to deal with crying plastic windows? This is what we plan to talk about in this article.

Crying plastic windows: cause and effect

So, with the onset of cold weather, condensation began to form on the surface of your windows. No, regular wiping with a rag is not enough. Of course, you can try, but if you do not find the main cause of moisture loss, there is a high probability of mold and mildew forming on the windows.

Important! Most owners, when such a problem arises, immediately begin to blame everyone: the manufacturer, the installer, the neighbor. However, I would like to immediately state that if your weeping plastic windows are literally flooded with water, this only means that they were installed in accordance with all standards. It's a paradox, isn't it?

If condensation forms on the windows, this means that they are sealed and are properly performing their functions of protecting the residents of the house from the penetration of moisture, dust and cold into the premises. However, this does not make it any easier.

But why didn’t the old Soviet windows cry? Perhaps they were better? Hardly. If those windows were provided with a good seal, and all the gaps and cracks were removed from them, they, just like the new plastic ones, began to not only cry, sob.

If the windows are not to blame, then what is the problem? Whether there is a ? It is worth noting that she is not alone. Have you ever wondered why condensation accumulates on windows most often during the cold season? It's all about the dew point.

Important! When air having a certain initial temperature and relative humidity, can no longer absorb moisture, condensation appears on the surface. That is, in this case, a dew point forms near the surface of the window.

There is a special table from which you can calculate the dew point. It shows the three most important values: air temperature, its relative humidity and surface temperature.

All this seems complicated at first glance. If you have no desire to figure everything out on your own, you can contact our specialist who will be happy to answer all your questions.

Causes of condensation

So, we figured out that the condensation that appears on the window due to the dew point is to blame. But why is all this happening?

  • Carrying out repair work.
  • A large number of residents.
  • Poor ventilation.
  • Wide window sill.
  • Poor heating.
  • Overdoing it with indoor plants.
  • Etc.

If you look at it this way, the appearance of condensation is affected by everything that changes the humidity and temperature in the room, and you shouldn’t forget about the surface of the window.

Important! In general, the reason for crying plastic windows lies in the living conditions, but not in the technical condition of the window.

Weeping windows: what to do, how to fight?

So, we figured out the reasons for the appearance of condensation on windows. Now, it remains to understand what to do with it. Wiping windows with a rag is not an option. But achieving a uniform distribution of temperature and humidity indoors is a completely adequate solution to the problem. According to sanitary and hygienic standards, the humidity in the room should not exceed 45%, and the temperature should not be lower than 20 degrees Celsius. If you maintain such readings, then most likely the windows will not cry.

If at first glance everything seems to be in order with humidity and temperature, but the problem still does not go away, you will have to dig deeper. Do you use micro-ventilation when the temperature outside is sub-zero? You shouldn't do that. The fact is that due to such manipulations, the window freezes strongly, and as a result, a dew point forms on its surface (see table). But do you need to ventilate the room? Of course it is necessary. Open window sash plow for 5-6 minutes. This period of time is quite enough to, firstly, remove from the premises excess moisture, secondly, to saturate the air with oxygen, and thirdly, not to lose precious heat.

How to deal with crying plastic windows if there are a lot of indoor plants on the windowsill? Everything is very simple here - put them away somewhere. Don't want to do this? In this case, you will have to rack your brains and do forced ventilation or additional heating of the double-glazed window. What to give preference to is up to you.

Sometimes the reason for the appearance of condensation on windows is wide window sill. It simply blocks the heat from the battery aimed at heating window design. Changing a window sill is, of course, a troublesome task, but there is no need to do everything yourself. The Teplo Doma company has excellent specialists who will be happy to help you solve all your problems with windows.

Weeping windows in Moscow: diagnostics and repair

If condensation forms on your windows, which subsequently turns into drops of water that form puddles right on the windowsill, then you definitely need to eliminate the cause of its appearance and move the dew point. The specialists of the Teplo Doma company will take on this work with great pleasure. Our company has extensive experience in solving these types of problems. Don't waste your precious time when you can just call.

The question is why new plastic windows cry in wooden house, is not unusual, since there are many reasons for this, starting with faults in the building itself and ending with problems in the window itself. But before blaming a company for installing a bad product, you should figure it out yourself and solve the problem as quickly as possible.

Causes of the problem

Such formation can be caused by a number of sources. The main reason for window fogging is high humidity air in the house. During frosty periods, the temperature of the window surface decreases. In this case, a temperature is reached that, while cooling the air, cannot absorb all the moisture. A similar phenomenon can be observed on the mirror when bathing in the bathroom or on glasses when entering a warm room from a cold room.

The main reason for fogging windows is poor ventilation.

If problems arise with windows, then the problem lies in a faulty ventilation system. Ventilation is often installed in the kitchen and bathroom. If the hood is not cleaned, then over time it can collect a lot of debris and fail.

In addition, new windows have a high degree of impermeability, which prevents air from the street from entering the house. Therefore, as a result, condensation forms, since there is a constant change of heat in the house, stagnant air comes into contact with the cooled glass. Often this unpleasant situation occurs in rooms where people work, in the kitchen with many functional household appliances or bathroom.

In addition to the tightness, the window itself may have an overly wide glass unit. Only ventilating the rooms will help regulate the level of moisture in the house; you can use an air conditioner, but to really have a productive result, you need a good and high-quality system. It is best to pay attention to their thickness when installing double-glazed windows. Universal and optimal thickness- up to 7 cm. Large thickness will interfere with other characteristics of the window.

Also cause a similar problem to windows in wooden building can:

  • construction or renovation work indoors where wet processes are used, plastering, Painting works, whitewashing ceilings, etc.;
  • redevelopment of the building, in which the rules when designing ventilation may not be taken into account and violated;
  • destruction of interior partitions.

Solution

What to do to eliminate an unpleasant situation? Below are some recommendations:

  1. It would be nice to purchase windows with two cameras. The second chamber will be able to maintain temperature, eliminating sharp drop between inner and outer glass.
  2. Purchase tilt-and-turn fittings for windows, which will delight you with natural winter ventilation. With a certain turn of the handle, a small gap of up to 3 mm is formed. Such a small gap not only protects against the possibility of catching a cold and getting sick, but also maintains enough space in the room. comfortable temperature air and humidity.
  3. If possible, do not install wide window sills. They promote the free movement of warm air around the entire perimeter of the window.
  4. Try to ventilate the room regularly and several times a day, at least for 5 minutes. All accumulating room moisture should come out.
  5. The solution to the problem begins with the correct and high-quality assembly of plastic windows in the house. Improper installation results in the appearance of condensation, incorrect temperature distribution on the slopes, and then they can bloom.
  6. In case of extreme cold, a few burning decorative candles can help. It is enough to place 2-3 candles on the windowsill closer to the glass. It's simple and cheap way, but the result is quite significant. The solution to the problem is not in the heat from the burning of a candle, but in the heat transfer from the process of its combustion. The candle also benefits indoor plants because it brings their favorite carbon dioxide closer to them.
  7. An exotic option is to cover the glass with film or foil and apply low voltage (up to 24 V) to it, creating the effect of an electric heater.
  8. Use regular fans. Although they are usually used in hot weather, they may also be needed in winter time for the same purposes, since they will create air movement. Therefore, we install a fan near the windows and select the minimum airflow mode. It would be good if the fan's action extended to several windows.
  9. Buy special aerosol Anti-fog windows, which is used for proper air condensation in cars. It's possible that this chemical method will not be able to completely solve the problem, since aerosols are very expensive and contain various specific chemical substances.
  10. One advanced way to solve the problem is to design convection screens. If there are no plants on the windowsill, the question of why the windows are crying is tormented, then technology lovers can make narrow plates that can transport warm steam from the radiator into the window cavity. The plate is attached to the window sill at an angle of up to 60 degrees. Then you can achieve that part of the heat will be directed and warm the glass. By showing some imagination, these screens can be made into an original part of the decor in the room. However, remember that this design is very painstaking work.

Conclusion

You need to choose high-quality and proven products to avoid the problem " crying windows", carefully monitor the technology for installing plastic windows in a wooden house. And then regularly monitor the temperature and humidity in the house.

If the windows are installed correctly and airtight, then you need to calm down and realize that the problem is purely aesthetic, since the windows themselves do not suffer or deteriorate from excessive moisture.

Such an unpleasant phenomenon as condensation on windows appears at any time of the year due to exposure to various factors. Although metal-plastic and wooden crafts are capable of serving for many years, but still people often encounter the appearance of drops on the glass, and then on the windowsill. It is important to understand the cause of this phenomenon and eliminate it. Why windows “cry” is described in the article.

Physical properties of condensate

Ice becomes water due to heating, and with a decrease in temperature the reverse process occurs. It is called moisture condensation. Air with high temperature includes liquid in the form of vapor. With cooling the situation changes. Air cannot hold much liquid as it decreases in volume, and moisture remains in areas with lower temperatures.

The glass of the window is considered the coldest place in the house, since it borders on the street, so condensation appears on it. At very low temperatures outside it becomes ice. At first glance, it may seem that condensation is not dangerous. But with frequent formation of liquids, they become wet construction products, after which the rigidity of the structure weakens and the formation mold fungus. Therefore, it is important to know why the windows in the house “cry”, as well as how to fix it.

Causes

One of the important functions of windows is to protect your home from freezing. But not all structures fulfill their purpose efficiently, since they are not operated according to the rules. Why do windows “cry”? Exist following reasons of this phenomenon:

  1. There is a big difference in temperatures inside and outside.
  2. High air humidity inside.
  3. Wide window sill above the radiator.
  4. Poor ventilation.
  5. Failure to comply with window operating modes.
  6. Rare ventilation of the room.
  7. Wrong window selected.
  8. Presence of plants on windowsills.

There is another reason why windows “cry”. Moisture appears on glass due to errors during the production of products, as well as inaccuracy during the installation of double-glazed windows. These reasons also apply to why wooden windows “cry”.

Ventilation

Even after installing a new window, smudges often appear on the glass and puddles on the window sills. Why do plastic windows “cry” and what to do in this case? The main task is to normalize the microclimate of the room. It is necessary to reduce humidity and ensure heating of the inner glass (if the package is two-chamber).

First you need to check if the ventilation is working. The system must delete wet air. When clogged, it accumulates inside and then settles on the windows. There is probably dust and dirt inside the air conditioning system, which makes all work difficult. It’s easy to check the level of blockage - you just need to hold a lit match or lighter to the outlet. If the fire goes out or fluctuates, then the ventilation is working, otherwise it needs to be cleaned.

Windowsill

Located above heating system, interferes with proper air circulation. This may also be one of the reasons why windows “cry”. Necessary heat does not enter the structure, and when cooling, water appears on it.

This problem can be eliminated by reducing the window sill so that warm air from the battery is directed to the window. If possible, the heating radiator should be pulled out. It’s even more convenient to find another method of heating the window.

Plants

And they “cry” because of flowers? The presence of plants on the windowsill disrupts the normal behavior of green organisms, filling the air with moisture, which causes fogging of the glass. If you remove plants from the window, you will be able to get rid of condensation.

Double-glazed windows modes

Why do plastic windows “cry” if the above factors do not exist? All double-glazed windows have 2 operating modes - summer and winter. If you do not switch from one to another in a timely manner, condensation appears, since inner side gets very cold.

Before cold weather (in October or November), it is advisable to switch the product to winter mode. Condensation often appears indoors, where the windows are rarely opened. In this case, ventilation is necessary for at least 15-20 minutes every day. This ensures not only good air circulation, which protects against condensation, but also supplies Fresh air, which has a positive effect on breathing.

You can insulate the space around the window. It is advisable to work with drywall. This material has excellent thermal insulation properties. It is necessary to insulate window slopes, area under the windowsill, outer wall. The better the quality of plasterboard finishing, the lower the risk of condensation. An increase in temperature in the house leads to insulation of the space near the window. These steps are easy to perform independently.

Production and installation of double-glazed windows

Although plastic window installers are professionals, even they make mistakes. Mistakes are also made by residents of premises where structures are being changed. In this case, you also need to know what to do. Why do windows sweat and “cry”? This is due to several reasons:

  1. Inaccuracies during the design or manufacture of windows.
  2. Purchasing the wrong glass unit.
  3. Poor installation.

Poor quality structures need to be corrected or disposed of. Buyers should choose their windows carefully. If the product will be installed inside rooms or on a loggia, you must purchase two-chamber model. Products with 1 chamber are ideal for a room bordering a glazed loggia (since it does not need additional insulation).

For reasons of economy, many people choose thin glass, but they do not adequately protect from the cold. In addition, condensation will appear on such products. When does replacement occur? plastic products on wooden ones, you need to prepare for changing the ventilation mode. PVC is a sealed material inside, and there are gaps in the wood through which air is exchanged.

If we compare plastic and wooden structure, then one difference can be detected - the inner glass of the first has a lower temperature, so it condenses faster. Construction errors are as follows:

  1. Improper foaming of cracks.
  2. The appearance of a “cold bridge” - the area where plastic or wood joins the side of the wall with a negative temperature.
  3. Blowing of masonry - appears with the destruction of horizontal or vertical seams between bricks.

If you want to purchase a durable product, it is important to control all stages of window installation. Also, you should not buy a wide window sill. These are the main reasons why windows sweat and cry. It is necessary to identify the cause of this phenomenon and eliminate it.

Wooden windows

Wood allows air to pass through better, so condensation appears less on such structures. But if fogging occurs, then to get rid of the problem you need to take into account how they were insulated. To normalize the microclimate in a room with double-glazed windows made of wood, you need to follow simple recommendations:

  1. Remove the sealant and mounting foam from the top of the frame and look at the condition of the glass. If condensation appears, it must be left window box without removing parts until it is completely dry. You can speed up the process by blowing it with a heat gun or a fan with warm air.
  2. Condensation may occur due to incorrect installation heating radiators or their poor quality. Windows often sweat and cry because thermal system is far away. To eliminate condensation, you should move it to double-glazed windows.
  3. The tree is considered more sensitive to air flows compared to plastic. Drops on the glass may appear because the door to the room is not closed or the tap is leaking. Such penetration of moisture into the air should be prevented.
  4. Washed clothes that dry on radiators also have a negative effect on windows.
  5. Blackout curtains that darken the room increase the likelihood of condensation.

It should be taken into account that wooden window products are better than PVC, since they form little moisture on the glass. The structure of their surface transmits and evenly distributes heat.

Window Treatment

Why windows “cry” and what to do in this case is of interest to many people. This drawback can be eliminated by regular processing of products:

  1. If possible, you can purchase special means designed to eliminate condensation. When applied, they form an invisible film that repels water. You can buy them in stores household chemicals. Before use, you must study the instructions.
  2. Window treatment is considered an effective method. saline solution. To do this you will need salt (1 tablespoon) and water (5 liters). The solution must be filtered to remove undissolved crystals. Then you can wipe the window with the product. If streaks or white spots appear after treatment, add a little water to the solution, after which you can wipe the structures again.
  3. A soap solution will do. It will take some water and detergent. A microfiber cloth should be moistened in the prepared solution, wrung out and treated with the window. Then you need to wash the window clean water and wipe with a dry cloth.
  4. A solution based on water and alcohol. This method should be used when the house is cold. You need to add a little alcohol. The product is easy to apply, creating protection against moisture.

other methods

Here are some more tips:

  1. You can get rid of condensation with decorative candles. To do this you need to buy several decorative candles, better than big ones, light them and place them on the windowsill. It was noticed that this normalizes air circulation.
  2. The “Second” product is suitable. The liquid should be sprayed onto the problematic structure, and then wiped dry with newspapers.
  3. Fans allow you to normalize air flow. The device must be pointed at the window, and after 10-20 minutes the problem will disappear.
  4. You can rub the windows with a mixture of glycerin and alcohol. The ratio of substances should be 1:10. Just first you need to wash the windows with warm water and wipe them. After this, you can apply the mixture and leave it without rinsing off.

It is important to monitor the condition of double-glazed windows by following the rules for stabilizing the microclimate. If you neglect the advice, then even on two-chamber and reliable structures condensation appears in winter and at other times of the year. You need to know not only why plastic windows “cry”. How to deal with this is an important question. The following recommendations should be followed:

  1. Check ventilation operation regularly.
  2. Ventilate your home for 10-15 minutes every day.
  3. Do not choose single-chamber kits for replacement.
  4. Monitor the thorough foaming of the joint between the frame and the wall and the remaining stages of installation.
  5. Do not choose wide window sills that cover the radiator.
  6. If the double-glazed window has several modes, then change them according to the time of year.
  7. Perform sealing of slopes.
  8. Maintain normal humidity - 45-60%.

As you can see, glass can sweat various reasons. Carrying out simple rules, you will be able to get rid of condensation. Then the glass will always be clean and beautiful.

Weeping windows are a fairly common problem among both apartment owners and private home owners. As a rule, the problem of condensation formation is encountered during the cold season. Many people think that only plastic windows cry, and that old wooden windows avoid this problem. Deep misconception. If in wooden windows seal all the cracks, equip them with a good seal and completely eliminate blowing, then condensation will form on them with the same efficiency.

Are you tired of walking around the house and wiping foggy windows? Do you want to understand the problem and fix it forever? This article will help you with this. Don't have time for this? Contact the Teplo Doma company. We deal with all types.

The proposed material will discuss the reasons why plastic windows cry, as well as several ways to solve this problem. So here we go.

Plastic windows are crying a lot: who is not to blame?

First of all, I would like to immediately note the innocent. When installing plastic windows, people spend a lot of money. Naturally, in return you want to get coziness, comfort and warmth in the house. Well, there is no desire to associate plastic windows with streams of condensation running down the surface. Therefore, people take a rag in their hand and begin to wipe away the resulting moisture. But this does not help, and condensation forms again.

And this is where the search for the culprit begins. Of course, you don’t want to blame yourself first of all. That is why installers, weather, window manufacturers, poor quality become to blame metal-plastic structures And so on and so forth. However, here is the paradox - if plastic windows cry in winter, then this, on the contrary, proves the innocence of the manufacturer and installers. How so? But you will understand this when you figure out why plastic windows cry in winter.

Why do plastic windows cry?

So, the most common reason that condensation appears on windows is current interpanel seams. During installation, the joints and seams must not only be sealed with polyurethane foam (and with high quality), but also treated with sealant. It will be better if, during installation, specialists additionally lay waterproofing material. In this situation, you will never encounter leaking interpanel seams. Otherwise, moisture will begin to creep into your home. First she will find a loophole in the seam, then in polyurethane foam, and now it is already in insulation, which is capable of storing it for a long time and giving it away. Moisture evaporates, usually into the room, since it is warm there. Well, then it just falls out in the form of condensation onto the plastic window. This is how a few unsealed joints can affect the comfort of a home.

To prevent this from happening, during installation you should insist on observing all necessary steps. If you have already encountered a problem, then it will help to solve it good master. In order to detect such a problem, you will need special equipment, with which a specialist will find the leak and fix it quickly and reliably.

Why is this happening?

It’s clear that condensation on windows is quite unpleasant. Moreover, this is not the only problem. Condensation is just an unpleasant consequence. But a consequence of what? Combinations of room temperature and relative humidity when in contact with a colder surface. In this case, the glass unit acts as the surface.

Why do plastic windows sweat and cry? Warm air, saturated with room moisture, comes into contact with a cold window. What is the result? If the temperature of the glass unit is below the dew point, the air in the immediate vicinity of it is no longer able to absorb moisture, as a result, condensation begins to form on the surface of the window. That's all.

What kind of dew point is this and how to determine it? Its value can be taken from the table presented.

That is, now it should have become clear to you why plastic windows in the house cry. It's all the dew point's fault. But what provokes its appearance?

Why plastic windows cry: reasons

In short, the main reasons have already been named: temperature and humidity. That is, it’s worth putting them in order, and the problem will be solved. According to sanitary and hygienic standards, the recommended room temperature is not lower than 20 degrees, as for the relative air humidity, it should be approximately 45%. By following these rules, in most cases it is possible to avoid a situation where plastic windows freeze and cry.

In general, here is a list of reasons influencing the appearance of condensation:

  • Poor ventilation.
  • Wide window sill.
  • A large number of indoor plants.
  • Wet weather.
  • Lots of people in the room.
  • The room is poorly ventilated.
  • Repair work.
  • Weak heating.
  • And etc.

Let's try to explain.

If indoors poor ventilation, which means the air is stagnating. If the air stagnates, moisture remains in it. If moisture remains in it, it will eventually fall out in the form of condensation on the window.

How wide window sill got into the reasons for crying plastic windows? Radiators in every house are located under the window. If the window sill blocks the flow of warm air to the window, the surface of the glass unit will cool more strongly, and this will inevitably cause a dew point to appear.

Houseplants absorb and release a lot of moisture. If you don't put it anywhere, it will fall out in the form of condensation.

Why do plastic windows cry? On the street wet weather. How is this related? Everyone is trying to ventilate the room more often. But few people think about the fact that the humidity outside can reach 100%. When you ventilate a room, you introduce moist air inside. Yes, perhaps the house becomes fresher, since air saturated with oxygen enters, but at the same time it is also saturated with moisture. Many people forget about this. If the room is not additionally dried, condensation cannot be avoided.

If in a small unventilated room there is many people, then sooner or later the air there will be saturated with moisture. Even with normal breathing, one person releases about 50 grams of water per hour. Is it worth talking about how much moisture enters the air during bathing and cooking?

Repair work- this is always the way to damp room. We will not go into details; we will limit ourselves to one rhetorical question. Where does the moisture go when, for example, cement mortar drying out?

Weak heating. If the room is poorly heated and it is frosty outside, then condensation in the form of ice will appear at the dew point.

The reasons seem to have been sorted out, but what to do next? More on this later.

We declare war on crying windows

Plastic windows sweat and cry: what to do? Of course, take action. Moreover, the faster, the better. If there is regular condensation on the windows. This means that the air in the room is most likely oversaturated with moisture. A high humidity, as is known, leads to the formation of pathogenic fungi, which in no way can have any effect beneficial influence on human health.

The first step is to make sure that the room temperature, as well as the relative humidity, meet the standards. To do this you need to purchase regular thermometer and a hygrometer. As already mentioned, the temperature should be at least 20 degrees and the humidity should be about 45%. If you are convinced that the air in the room has different values, try to bring them back to normal.

First, let's go through the reasons and try to eliminate them:

  • Provide good ventilation.
  • Reduce the window sill.
  • Move half the plants to another room.
  • Try to control humidity during bad weather.
  • Reduce the number of people by square meter. Just a joke, of course. Just, as in the previous case, you need to try to control the humidity.
  • It is better to ventilate the room.
  • There is no escape from repair work.
  • Make sure you have good heating.

How to deal with crying plastic windows? Try to comply with everything that has been listed.

One thing remains unclear - how to control humidity? If everything is extremely simple with the temperature in the room, then what about the humidity? The most common way to get rid of moisture is a combination of ventilation and heating. Due to good heating and constant ventilation of the room can, although not easily, get rid of moisture.

Thanks to modern technologies, there is another method called a dehumidifier. The device, of course, is expensive, but in some cases it is very useful. A dehumidifier can control the humidity in your home for a modest fee of 250Wh.

Plastic windows are crying: how to fight? Instead of conventional double-glazed windows, you can install double-glazed windows consisting of low-emission glass. However, keep in mind that you will, of course, solve the problem with condensation, but you should also not forget about air humidity.

That's probably all.
