weeping windows- a fairly common problem, both among apartment owners and among owners of private houses. As a rule, the problem of condensation is encountered in the cold season. Many people think that only plastic windows cry, and old wooden ones bypass this problem. Deep delusion. If all the cracks are sealed in wooden windows, equipped with a good sealant and the blowing is completely eliminated, then condensate will form on them with the same efficiency.

Are you tired of walking around the house and wiping misted windows? Do you want to understand the problem and fix it permanently? This article will help you with this. No time for this? Contact the company Heat House. We deal with all kinds.

The proposed material will consider the reasons why plastic windows cry, as well as several ways to solve this problem. So, we're getting started.

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

First of all, I would like to immediately mark the innocent. 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 condensate running down the surface. Therefore, people take a rag in their hand and begin to wipe the moisture that has formed. But this does not help, and the condensate forms again.

And this is where the search for the culprit begins. Of course, you don't want to blame yourself in the first place. That is why installers, the weather, window manufacturers, the poor quality of metal-plastic structures, and so on and so forth become to blame. 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 the windows is the current interpanel seams. When installing, the joints and seams should not only be blown out with mounting foam (and with high quality), but also treated with sealant. It would be better if, during installation, specialists additionally lay waterproofing material. In this situation, you will never encounter the fact that interpanel seams flow. Otherwise, moisture will begin to make its way into your house. First she will find a loophole in the seam, then in mounting foam, and now she is already in a heater, which is able to save it for a long time and give it away. Moisture evaporates, as a rule, into the room, because it is warm there. Well, then it just falls out in the form of condensate on a plastic window. This is how a few unfinished joints can affect the comfort in the house.

To prevent this from happening, during installation, you should insist on observing all the 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 a leak and fix it quickly and reliably.

Why is this happening?

It is clear that the condensation on the windows is quite unpleasant. Besides, this is not the only problem. Condensation is just an unpleasant consequence. But the consequence of what? Combinations of room temperature and relative humidity when in contact with a colder surface. In this case, a double-glazed window acts as a 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 double-glazed unit is below the dew point, the air in its immediate vicinity is no longer able to absorb moisture, as a result, condensation begins to form on the surface of the window. That's actually all.

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

That is, now it should have become clear to you why the plastic windows in the house are crying. It's all about the dew point. 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 is worth putting them in order, and the problem will be solved. According to sanitary and hygienic standards, the recommended indoor temperature is at least 20 degrees, as for relative humidity, it should be about 45%. If these rules are followed, in most cases it is possible to avoid a situation where plastic windows freeze and cry.

In general, here is a list of reasons that affect the appearance of condensate:

• Bad 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 stagnant. If the air stagnates, then moisture remains in it. If moisture remains in it, then it will eventually fall out in the form of condensate on the window.

how wide window sill fell into the cause of crying plastic windows? Radiators in every house are located under the window. If the window sill blocks the flow warm air to the window, the surface of the double-glazed window will cool more strongly, and this will inevitably cause the appearance of a dew point.

Houseplants absorb and release a lot of moisture. If you do not put it anywhere, it will fall out in the form of condensate.

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

If in a small unventilated room is many people 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. Needless to say, how much moisture enters the air when bathing and cooking?

Repair work- this is always the way to a wet room. We will not go into details, we will limit ourselves to one rhetorical question. Where does the moisture go when, for example, the cement slurry dries up?

Weak heating. If the room is poorly heated, and it is cold outside, then together with the dew points condensation will appear in the form of ice.

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

We declare war on weeping windows

Plastic windows sweat and cry: what to do? Of course, take action. And the sooner the better. If condensation regularly falls on the windows. So, most likely, the air in the room is oversaturated with moisture. BUT high humidity, as you know, leads to the formation of pathogenic fungi, which by no means can have beneficial effect on human health.

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

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

• Make good ventilation.
• Reduce window sill.
• Move half of the plants to another room.
• Try to control humidity during bad weather.
• Reduce the number of people square meter. Joke, of course. Simply, as in the previous case, you must try to control the humidity.
• It is better to ventilate the room.
• From repair work nowhere to go.
• Take care of good heating.

How to deal with crying plastic windows? Try to follow 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 good heating and constant ventilation of the room is possible, albeit not easy, but to get rid of moisture.

Thanks to modern technologies, there is another way called "air dryer". 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 250 Wh.

Crying plastic windows: how to fight? It is possible to install double-glazed windows consisting of low-emission glasses instead of conventional double-glazed windows. However, keep in mind that you, of course, will solve the problem with condensate, but you should not forget about the humidity of the air either.

That, perhaps, is all.

Weeping windows: repair in Moscow

If you have a problem, but there is no time to solve it, then Teplo Doma will be happy to help you. Why do plastic windows cry in an apartment, in a house: what to do, reasons, how to fight? Lots of questions you don't know the answers to. Just contact our online consultant. Soon a master will visit you, look at the windows and help you fix any problem associated with them.

Relatively recently appeared in our apartments, at first made a splash. After all, their advantages, such as excellent sound and heat insulation, beautiful appearance, ease of care, no need for regular repairs and seasonal insulation, were obvious to everyone. However, it soon became clear that their main property - tightness - is at the same time a big drawback, since it is because of it that plastic windows “cry”. What to do? There are several answers to this question, but before moving on to them, you should figure out why condensation forms on their inner surface.

What causes fogging of PVC windows

According to experts, in 99% of cases, plastic windows “cry”, because after installing them, the room turns into a hermetically sealed “jar”, ​​where there is no ventilation that allows fresh air to enter the room, and exhaust air to leave it. In addition, water vapor emitted by residents and indoor plants, as well as being a consequence of household activities.

Why wooden windows don't sweat

Most often, those who installed plastic windows in their apartments consider them to be “guilty” of the fact that the humidity in the apartment has increased. How else? After all, condensation did not form on wooden windows or appeared extremely rarely and in small quantities. The fact is that the old-style frames had many small slots, which, together with the hood connected to a special shaft, formed a ventilation system that did not allow exhaust air and vapors to stagnate in the room. So today, changing wooden windows on more airtight ones, the owners violate the ventilation, and the plastic windows "cry". This is absolutely inevitable, unless, of course, additional measures are taken. In addition, sometimes double-glazed windows are not blown with hot air from radiators, which would prevent the formation of condensate. The reason is the too wide window sill or the presence of “wrong” curtains and other objects that violate the natural convection in the room.

“Tears” on a double-glazed window as a result of poor-quality installation and design flaws

Are your plastic windows "crying"? What to do depends on the cause of this phenomenon. For example, sometimes it can be caused by non-compliance with the technology at the stage of window production or improper installation. Therefore, if you are sure that everything is in order with ventilation and heating in your house, and your windows are “under warranty”, then it makes sense to call the craftsmen from the company from which you purchased them and demand to check if everything is in order . By the way, if plastic windows “cry” (what to do will be described below) from the inside, then this is usually the result of marriage, or rather, insufficient tightness of the double-glazed window, and you can safely demand to replace them.

The two easiest ways to get rid of window “tears”

Does the above mean that you should not install double-glazed windows in your house? Everyone makes such a decision for himself, comparing all the advantages and disadvantages of both options, as well as familiarizing himself with the ways to get rid of condensate on their inner surface. For example, the most the easy way to get rid of fogging of PVC windows is regular airing of the premises. It can be done either by setting the handle on the frame to the ventilation position (if it is provided for by the design of a particular model), or by opening the windows for 5 minutes every 2-3 hours. It should be understood that the second option will lead to large heat losses and is not suitable for those who disappear all day at work. As already mentioned, one of the reasons why plastic windows “cry” is poor convection. To eliminate it, it is enough to make several holes in the window sill, allowing warm air to heat the glass and reduce the “dew point”, and you should also, at least in the cold season, abandon curtains and shutters mounted directly on the frame.

Why plastic windows "cry": what to do (photo)

In addition to those mentioned above, there are more radical measures that require some financial costs. For example, those who are interested in why plastic windows “cry” (you already know what to do so that the window sill does not interfere with convection) have probably seen photos in which oblong devices of incomprehensible purpose are installed on the window frames. These are ventilation valves that, without human intervention, provide ventilation of the premises. Moreover, there are models that operate autonomously, and they do not require power supply. The only thing that needs to be done in order for the valve to work as it should is to check and, if necessary, clean and repair the exhaust ventilation in the apartment. Moreover, there are models that can be installed on an already mounted PVC window.

Why plastic windows "cry": what to do (reviews on measures)

Despite everything, it should be recognized that double-glazed windows have a lot of advantages. Therefore, having found out why plastic windows “cry”, many do not refuse to install them, but take the necessary measures to eliminate the shortcomings. Judging by the reviews, the installation of valves allows you to quite effectively cope with the formation of condensate on the windows and at the same time does not violate the sound insulation of the premises. In addition, such devices have a low cost, which makes them accessible to everyone.

Some apartment owners prefer to solve the problem of high humidity by installing split systems. This is a good but expensive option. At the same time, you should make sure that the selected model of the air conditioner has the necessary function of drying the air if its humidity exceeds certain indicators.

How to choose the “right” plastic window

In order not to ask questions after repairs in the apartment why plastic windows are “crying”, what to do and who to contact, it is better to immediately install a model that will not be subject to condensation. First of all, it is better that it be with an already built-in ventilation valve, so that later you do not have to install such a device. Also, experts recommend giving preference to two-chamber models that are less prone to condensation in the edge zones, and check whether the micro-ventilation function is provided. In general, you should immediately refuse to purchase a double-glazed window if the guarantee for it is less than 5 years.

Now you know why plastic windows "cry". What to do - you also already know, it remains to choose a good exhaust valve and enjoy all the benefits of double-glazed windows.

The most famous disadvantage of PVC windows is fogging, the appearance of condensate. Condensation flows down the glass, puddles appear on the windowsill. In a neglected form, this problem leads to serious consequences: the walls begin to collapse, a fungus starts on them. The air in the room becomes suffocating. Why do plastic windows leak?

Causes of condensation

There are two of them, and they work together:

Increased humidity in the room or directly in the glass area;

A sharp contrast between the temperatures of warm air and the cold surface of the package.

Condensation occurs when heated steam comes into contact with ice glass.

What causes these two conditions?

There is a single package on the window, there is not enough air gap to keep the inner glass warm;

Video "Why plastic windows flow and how to deal with it":

Window seals broken. Due to poor-quality installation or due to shrinkage of the house, there are gaps between the frame and the walls of the opening. Through the cracks, cold outside air flows to the glass;

A window sill that is too deep overlaps the radiator located under it from above. Convection currents do not reach the glass;

Thick curtains can also be a reason why plastic windows leak - they prevent free convection;

Poor ventilation in the apartment. Sometimes, after installing new windows, residents by inertia continue to ventilate the room in the same mode as before. Previously, when there were old through-blown windows, this was enough. New hermetic structures do not “breathe”, there is no natural ventilation, and humidity does not decrease.

Humidity is increased due to various reasons:

Vapors come from the kitchen, bathroom;

From indoor flowers on the windowsill;

You regularly dry wet mittens on the radiator;

Recently renovated, dehydrated Decoration Materials: putties, emulsion paints, wallpaper glue, etc.

What to do when windows leak

Replace the package with a double one. This is not the case when you can save;

Check the adjoining frames to the slopes for cracks.

Tip: if the cracks are not visible to the naked eye, and the draft is not clearly expressed, you can test the perimeter with a lit match.

If the installation was carried out recently, call the masters to eliminate their own defect;

If there is nowhere to turn, and plastic windows are leaking, seal the cracks with foam yourself. It also makes sense to insulate the outer slopes with foam;

Provide full ventilation: supply valves, a fan or air conditioning with a dehumidification function, regular ventilation in intensive mode;

Close the doors to the kitchen when cooking and to the bathroom;

Do not keep indoor flowers and other sources of moisture near the windows;

Replace the window sill if it is too wide, ensure a free flow of warm air to the glass.

If wooden windows flow

New wooden window structures are arranged in the same way as plastic ones and wooden windows flow as well. And their frame covers are often airtight. Although wood is considered to "breathe", a new wooden window is the same hermetically sealed chamber as PVC. Accordingly, the prerequisites for sweating are the same.

Or the owners took too much care of sealing the old window, sealed it and completely filled all the cracks, joints, holes with sealants, insulation, sealants and foam. The result was a hand-made imitation of an airtight window structure, which is why double-glazed windows and windows flow.

This is not as paradoxical as it seems. When there are holey frames from Soviet times in the openings, it is cold in the house. Because of this, you decided to replace windows in our difficult time of crisis.

The house is cold because natural ventilation: the air is renewed through the cracks, the vapors leave, there is no strong contrast between the room and outdoor temperature. And new windows (or carefully clogged old ones) prevent free air exchange, that is:

Couples stay in the room;

It's hot in the house;

And at the same time, the glass itself can flow cold air, there are "cold bridges".

If wooden windows are leaking, then this is worse than PVC. Wood absorbs moisture and swells. If the fungus on the walls is quite treatable, then the destroyed, deformed, cracked frame is only a replacement.

To prevent this from happening, you need to remove heaters, seals, sealants from the frames and dry the window thoroughly with a building hair dryer. And after that, proceed to a full-fledged well-thought-out thermal insulation of the opening.

The article discusses why plastic windows flow, wooden ones and methods for solving this problem. The main thing is not to waste time and follow all the recommendations as quickly as possible.

Leaky windows are the most common winter problem faced by every second happy owner of plastic windows. And this is not so much a problem as a feature and a combination of circumstances. And no matter how strange it may sound, if your windows are leaking - this is the first sign that they are installed correctly, tightly and for centuries. As the notorious Elena Malysheva would say - this is the norm!

But! Puddles on the windowsills are completely useless to us, and mold and fungus - even more so. So right now you will learn 5 better ways solve the problem of leaking windows once and for all. But before we reveal the main professional window secrets, we will answer the most important question - why do windows leak? And someone, perhaps, even asks “why do we need all this?”.

Why are windows leaking?

This question is best answered by one of the masters, who has seen so many weeping windows in his life that he himself almost cries when frosts begin, which once again confirms that you are not alone in your problem. But Anatoly does not see the problem, which he wishes for everyone.

Polyansky Anatoly

Solves any problems with windows for 20 years. Almost a real window fairy, if not for the mustache. Everything will be fixed as quickly and efficiently as possible, immediately reassure and inspire hope for the future.

Have problems with windows? it right now!

How we tear from the heart.

Anatoly, don't torment us. Why do plastic windows leak so often despite being so expensive?

Well, firstly, not only plastic windows are leaking. Wooden modern windows with double-glazed windows are also often seen in this problem. The reason is not in the material, not in the price, not in the brand, not in the installer, and not even in the growing moon. The reason is only in three components: tightness, high humidity in the room and frost outside the window. In winter, which is logical, the temperature on the glass surface drops significantly and often reaches the dew point.

- The dew point sounds romantic, but not understandable to the layman. What is it?

The dew point is something that haunts you on an almost daily basis. Misted mirror in the bathroom after you took a shower. Fogged glasses after you went into a warm room from the cold. All these are manifestations of such a physical phenomenon as the dew point. If you allow me to be smart, this is the temperature at which air, with a certain temperature and humidity, can no longer absorb moisture.

- And what does this have to do with windows?

Directly. Outside the window is frost and the wind is howling, the husband wanted a hodgepodge, the child wanted pancakes. And now everything gurgles and sizzles on the stove, the humidity in the room rises, the glass, of course, is cold in winter, so what? Hello condensation! The windows are leaking, there is a puddle on the windowsill, the hostess is in a panic, the hodgepodge is boiled. And this is just one of the examples. You can cook nothing at all at home and be the happy owner of weeping windows. Drying laundry, flowers on the windowsill, an aquarium of some kind and your breath, finally, all this contributes to an increase in humidity and hello, the most popular winter problem, windows leak.

- Does it happen that there is none of this at all, but the windows still flow?

There is always a reason. If not an aquarium with goldfish, then, for example, "wet" construction works(painting, wall papering, etc.). Clogged ventilation, again. Plastic windows are airtight (if installed in accordance with all the rules and), fresh air from the street does not penetrate, ventilation does not perform its function. And the result is the same - stagnant air comes into contact with cold glass, condensation forms, and the windows leak.

- And where do windows leak most often?

In the kitchen, of course. Cooking, kettles, multicookers, the proximity of the bathroom - all this contributes to the appearance of such a problem. And the inhabitants of the upper floors still often suffer from ventilation, through which moisture enters and does not fresh air from all neighbors below.

- That is, the lower the floor, the better?

Is not a fact. The lower the floor, the closer the basement. Better in the middle, if there is a question of choice.

“Somehow we didn’t think of everything. Downstairs is bad, upstairs is bad, the kettle is boiling - bad.

We've got it all figured out. The fact is that the houses were built taking into account the fact that there will be a constant influx fresh air through the cracks in the windows. Sealed plastic windows + old ventilation = condensation on the windows, and even puddles on the windowsills. And if the frost is strong, then there is also frost. The problem is easily solved if, for example, forced ventilation fans are installed in the ventilation with check valve. It's like an option.

What other pitfalls are there? Suppose the house is new, and the ventilation is modern, and the floor is not the last, and the soup is cooked once a year, and the windows are leaking. Why?

Heating. Perhaps it is the reason. The apartment should be warm, the batteries should be in good condition and heat not just anyhow, but with all the best. And should be exclusively under the window! Batteries warm not only you, but also the window. Therefore too wide window sills, blackout curtains, hanging so that the flow of warm air to the window is difficult, or, even worse, batteries closed by something - all this can lead to the window leaking sooner or later.

- And what do you do when you come to a client with a similar problem?

I get a moisture meter. This is usually enough to make a diagnosis. And in 100% of cases, the windows are not sick.

- And then what?

So how do you live on? 5 simple ways to quickly fix the problem of crying windows.

Ventilate more often

Your task is to achieve adequate humidity and temperature in the room. Get in the habit of ventilating the apartment (especially the kitchen) more often, and this alone may be enough to stop the windows from leaking.

Optimum air temperature - not lower than 20C

Optimum relative humidity - no more than 45%

Important! In winter, it is better not to use micro-ventilation so that window fittings do not freeze.

Turn on the fan

Yes, yes, the one that you usually turn on in the summer, in the heat. Point it at a window and turn it on at the lowest speed. To achieve the effect, we need the movement of air near the glasses, and in such a simple way we will achieve it.

Why not? Excellent alternative solution if all other methods for some reason are not available to you or do not work. The problem will not be radically solved, but it will definitely become better.

Repair the hood

Windows leak if it is clogged and does not function well. This is very common problem old houses or new ones with homemade exotic redevelopment from neighbors.

Minimize Anything That Raises Humidity

Remove flowers from the windowsill, change thick curtains for lighter ones, do not cover the batteries with anything.

Was it too lazy to read everything? The whole point in a nutshell!

So, let's recap what has been said above. Windows are not to blame. The installers are not to blame. The profile is not at fault. The glazing is not to blame. And even Putin is not to blame. Basically no one is to blame. Weeping windows are physics. But it is in our power to reduce its manifestations to a minimum.

Minus temperature outside the window + humidity in the room more than 45% + clogged ventilation = condensation and frost on the window.

Ventilate more often, solve ventilation problems, release and adjust batteries.

Sometimes people, having installed plastic windows, are faced with a problem - when cold weather sets in, it is not clear why they begin to fog up and leak. This makes it difficult to see, worsens the lighting in the apartment, preventing the penetration of light.

Favorable conditions are also created for the appearance of fungi and mold. Many people think that installer errors are to blame for this, but there are many more factors that lead to moisture accumulating on the glass.

Why does condensation form?

There are many reasons why plastic windows in an apartment are leaking, and in order to get rid of condensation on the windows, you need to understand what exactly provoked it. It could be:

• violation of the movement of air in the room. When during the heating season the radiators heat up only a little, and the temperature outside is quite low, the window cannot be heated as needed;
• with hot batteries, condensation may occur due to the large protrusion of the window sill, which blocks the access of warm air directly to the glass;
• if protective screens are installed on the radiators, they prevent the flow of heated air flows to the bottom of the window;
• too humid air in the apartment. This can occur when drying laundry after frequent washing, cooking, etc.;
• No good ventilation(does not function or is clogged), as a result of which moist air does not escape;
• poor-quality installation with violations of technology - the gap between the opening and the window profile is poorly sealed. In addition, the tide may not be installed correctly - it is simply attached to the window, while it should be placed on the base of the solution;
• during installation, the level could be violated and a skew could form, so the leaf gaskets do not fit snugly;
• during repairs - when wallpaper has just been pasted, laid tile emit moisture, which condenses on the glass;
• the quality of the seal also plays a role, since a gap may form between the frame and the double-glazed window, from which cold will seep;
  the formation of condensate also depends on which fittings, as well as whether its installation meets the rules - whether it allows the doors to be tightly closed or not;
• this effect can be caused by poorly performed work on the insulation of external or internal slopes;
• the adjustment of the plastic window also affects the fogging of the windows: the fit of the sashes may be insufficient.

Preventive measures

They are used when there is a problem, but it is not too pronounced. One of the reasons why plastic windows leak in winter is the presence of pots with home flowers on the windowsill.

Live plants and the moist soil in which they grow very often lead to condensation. To get rid of it, it is enough to remove all flowerpots from the windowsill.

It is also necessary to regularly arrange ventilation, especially if the level of humidity rises from time to time.

Usually there are no vents in plastic windows, so you need to open the transom. This is true in the kitchen during cooking, as well as drying washed clothes in the apartment. In the kitchen, it is necessary to install a hood, and it is advisable to cook in pans closed with lids.

1. It is advisable to constantly keep the windows in micro-ventilation mode by turning the knob 45 degrees and making a gap for air to enter from the outside.
2. It is necessary to check how efficiently the ventilation in the apartment works - a thin sheet of paper should stick to the grating of the hole. If it does not hold, the ventilation ducts need to be cleaned;
3. In a single-chamber profile, the distance between the panes of the package is minimal, and there is only one air gap. Due to temperature fluctuations, especially in cold winters, condensation will inevitably form. It is better to choose a two-chamber profile.
4. If the slopes are not insulated, this must be done. Styrofoam can be used as an external insulation. cement mortar you need to carefully cover the gaps between the window and the opening. Styrofoam is not used for internal slopes. Basalt or glass wool is used here.
5. Reduce the width of the window sill or move the radiator a little further from the wall. Also, for better access to warm air, it is necessary to equip the window sill with convection grilles or drill holes in it. If decorative grilles are installed on the batteries, it is better to get rid of them.
6. Check window hardware for wear from time to time as it may need to be adjusted or replaced.
7. AT winter period it is necessary to transfer all windows to the appropriate mode of operation, using the eccentrics at their ends.
8. You can purchase a dehumidifier. But first, measure the humidity with a hygrometer. Humidity rate for comfortable living in the apartment should be 40-70%.

What to do if the plastic double-glazed window is of poor quality?

When the methods listed above do not help, and you cannot understand why plastic windows are flowing, it means that they are of poor quality. Perhaps a marriage was made during their manufacture, a base profile was used, or all installation conditions were not met. In this case, it will not be possible to eliminate it yourself.

Sometimes glasses fog up inside the bag. This means that it is necessary to remove and replace the seal or even the double-glazed window itself.

Do not think that you can do it yourself - only specialists can do it. There are certain nuances that you may not know about and make mistakes.

If the manufacturer or the company that carried out the installation gives a guarantee of at least a year, you can turn to them after identifying this problem in winter. They are obliged to eliminate the marriage or defects in the installation. Otherwise, you will have to purchase a new window and pay again for its installation.

Results

Conducting preventive measures or by following these tips, you can prevent condensation from forming on the windows. But if, having tried several methods, you have not achieved this, contact the specialists who installed the windows.
