Why windows "cry": possible causes and solutions to the problem

Such an unpleasant phenomenon, like condensation on windows,appears at any time of the year due to the impact of various factors. Although metal-plastic and wooden products can serve many years, but still people often encounter drops on the windows, and then on the windowsill. It is important to understand the cause of this phenomenon and eliminate it. Why the windows "cry" - described in the article.

Physical properties of condensate

Ice, thanks to heating, becomes water, and witha reverse process occurs by lowering the temperature. It has the name of condensation of moisture. Air with a high temperature includes a liquid in the form of steam. With cooling, the situation changes. Air can not hold much liquid, as it decreases in volume, and moisture remains in areas with a lower temperature.

Glass windows are considered the coldest place of the house,because it borders on the street, so condensation appears on it. At very low temperatures on the street, it becomes icing. At first glance, it may seem that the condensate is not dangerous. But with frequent formation of a liquid, building products become wet, after which the stiffness of the structure and the formation of a mold fungus decrease. Therefore it is important to know why the windows are "crying" in the house, and also how to eliminate it.

Causes

One of the important functions of windows is protectionhousing from freezing. But not all designs fulfill the function qualitatively, since they are not operated according to the rules. Why do the windows "cry"? There are following reasons for this phenomenon:

1. A big difference in temperatures inside and outside.
2. High humidity inside.
3. Wide window sill over the battery.
4. Low-quality ventilation.
5. Non-compliance with the operating mode of windows.
6. Rare airing of the room.
7. The window is not selected correctly.
8. Presence of plants on the windowsills.

There is another reason why windows "cry". Moisture appears on the glass due to errors during the manufacture of products, as well as inaccuracies in the installation of insulating glass. These reasons also concern why the wooden windows "cry".

Ventilation

Even after installing a new window oftenthere are stains on the windows and puddles on the windowsills. 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 the humidity and ensure the heating of the inner glass (if the package is two-chambered).

First, you need to check whether theventilation. The system must remove moist air. With clogging, it accumulates inside, and then settles on the windows. Probably inside the air conditioning system there is dust, dirt, because of what all work is difficult. Check the level of clogging is easy - you need to bring the lit match or lighter to the outlet. If the fire extinguishes or fluctuates, the ventilation works, or else it needs cleaning.

Window-sill

A wide window sill above the heatingsystem, prevents proper air circulation. This can also be one of the reasons why windows "cry". The necessary heat does not flow to the structure, and when it cools, water appears on it.

Eliminate this problem by reducingsill, so that the warm air from the battery is directed to the window. If possible, it is necessary to extend the radiator. And it is more convenient to find another method of heating the window.

Plants

Why plastic windows sweat and "cry" because ofcolors? The presence of plants on the windowsill disrupts the normal air circulation. Green organisms fill the air with moisture, because of which fogging of the windows is formed. If you remove plants from the window, you will get rid of condensation.

Modes of double-glazed windows

Why plastic windows "cry", if notof the above factors? In all double-glazed windows there are 2 operating modes - summer and winter. If you do not jump from one to the other in a timely manner, condensation appears, as the inner side is very cool.

Before the cold weather (in October or November) it is desirableperform the product's transfer to winter mode. Often the condensate appears inside the premises, where the windows are rarely opened. In this case, it is necessary to ventilate at least 15-20 minutes every day. This ensures not only a good circulation of air, which protects against condensation, but also fresh air that positively influences breathing.

You can warm the space around the window.It is desirable to perform work with plasterboard. This material has excellent thermal insulation properties. Insulate the window slopes, the area under the windowsill, the outer wall. The more finely finished the plasterboard, the less the risk of condensation. Increasing the temperature in the house leads to the insulation of the space near the window. These actions are easily performed on their own.

Production and installation of double-glazed windows

Although the installers of plastic windows areprofessionals, but even they have errors. Overshoes are allowed and occupants of the room, where the design changes. In this case, too, one must know what to do. Why do the windows sweat and cry? This is due to several reasons:

1. Inaccuracies during the design or manufacture of windows.
2. Acquisition of an improper double-glazed unit.
3. Poor installation.

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

Because of the savings, many choose thinglass, and in fact they will not protect in due measure from colds. In addition, such products will appear condensate. When the replacement of plastic products with wooden ones, you need to prepare for changing the ventilation mode. PVC is a sealed material that increases the humidity inside, and in the tree there are cracks through which air is exchanged.

If you compare plastic and woodendesign, you can detect one difference - the inner glass of the first has a lower temperature, so it quickly condenses. Construction errors are as follows:

1. Incorrect gaping of the slots.
2. The appearance of a "cold bridge" - areas of abutment of plastic or wood to the side of a wall with a negative temperature.
3. Blowing masonry - appears with the destruction of horizontal or vertical seams between bricks.

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

Wooden windows

The tree is better than air, so on suchcondensate appears less. But if fogging happens, then to get rid of the problem you need to consider how they were warmed. To normalize the microclimate in a room with double-glazed windows made of wood, one should follow simple recommendations:

1. Remove the sealant from the top of the frame andmounting foam, look at the state of the glass. If condensation appears, you must leave the window box without removed parts until it dries completely. Accelerate the process will blow out a heat gun, a fan with warm air.
2. Condensation may occur for a reasonincorrect installation of heating radiators or their poor quality. Often, the windows sweat and cry because the thermal system is far away. To eliminate condensation, you should transfer it to double-glazed windows.
3. The tree is considered more sensitive to airflows compared to plastic. Drops on the glass may appear due to the fact that the door to the room is not closed or the tap is leaking. Do not allow such penetration of moisture into the air.
4. Washing clothes, drying on batteries, also adversely affect the windows.
5. Dense curtains that obscure 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 Processing

Why do the windows "cry" and what to do in this case, many people are interested. The shortage can be rectified by regular processing of products:

1. If possible, you can purchase specialmeans designed to eliminate condensation. When applied, they form an invisible film that repels water. You can buy them at household chemistry stores. Before use, you must read the instructions.
2. An effective method is treating windowssaline solution. This requires salt (1 tbsp.) And water (5 liters). The solution must be filtered, eliminating the crystals which have not dissolved. Then the tool can wipe the window. If after processing there are stains, white spots, a little water is added to the solution, after which it is possible to wipe the structures again.
3. Suitable soap solution. It will take a little water and a detergent. A tissue of microfiber should be moistened in a ready solution, press and process the window. Then you have to wash the window with clean water and wipe it with a dry cloth.
4. A solution based on water and alcohol. This method should be used when the house is cold. Alcohol should be added a little. It is easy to apply, creating protection against moisture.

other methods

And here are some more tips:

1. Removing condensate can be decorativecandles. To do this, you need to buy a few decorative candles, better than large ones, light them, set them on the windowsill. It was observed that the air circulation is normalized.
2. Suitable tool "Second". The liquid should be sprayed on a problematic structure, and then wipe dry with newspapers.
3. Fans allow to normalize the air flow. The device should be sent to the window, and after 10-20 minutes the problem disappears.
4. You can rub the windows with a mixture of glycerin and alcohol. The ratio of substances should be 1:10. Only first you have to wash the windows with warm water, wipe them. After this, you can apply the mixture and leave it without rinsing.

Recommendations for the elimination of condensation

It is important to monitor the status of insulating glass,fulfilling the rules of stabilization of the microclimate. If you disregard the advice, even on two-chamber and reliable designs, condensation appears in winter and at other times of the year. It is necessary to know not only why the plastic windows "cry". How to deal with this is an important issue. It is necessary to follow the following recommendations:

1. Regularly check the operation of ventilation.
2. Every day for 10-15 minutes to ventilate the house.
3. Do not choose to replace single-chamber kits.
4. Control the careful sealing of the frame and wall junction and the rest of the installation steps.
5. Do not choose wide windowsills that close the battery.
6. If the glass unit has several modes, then change them by the time of year.
7. Carry out sealing slopes.
8. Maintain the humidity in the norm - 45-60%.

As you can see, the glasses can sweat for different reasons. Performing simple rules, you can get rid of the condensate. Then the glass will always be clean and beautiful.
