What to do if plastic windows in your house sweat from the inside - a folk remedy

Windows covered with sweat not only impair your view, but can also cause mold to grow in your home. Many housewives are concerned about the question: how to treat plastic windows against fogging? Any product that forms a slippery film on the surface will help: soap, glycerin, shaving foam. Droplets of moisture will not be able to stay on the glass, and the window will remain transparent under any circumstances.

What makes glass sweat?

Leaks on windows in your home can be caused by several reasons.

For example:

1. Increased humidity in the room and poor air circulation. Condensation especially accumulates on glass in the kitchen or bathroom due to frequent cooking and hanging laundry.
2. There is a big difference between the temperature outside the house and inside.
3. Insufficient circulation of warm flows from radiators and heating devices when it is wet outside and damp in the room.
4. Wide window sill. Air from the radiator cannot get to the window, and an unheated zone remains in its lower section.
5. Violations in window installation. To prevent windows from sweating, you should choose trusted manufacturers and high-quality materials. When saving on double-glazed windows or on installation services, work may not be performed according to standards with sealing violations. When the frame is skewed, the fit of the sashes is damaged.
6. Lack of transom regulation. When installing, it is important to focus on the quality of regulation of the window sashes.
7. Damage to the structure of the rubber seal. Depending on temperature and time, the material can harden and crumble, which leads to seal failure.
8. Clogged drainage holes located under the opening flap. Water flows through the drains from the outside of the window during ventilation; if clogged, excess moisture will penetrate onto the window sill.

Increased dampness renders window fittings and household items unusable. Condensation is the main reason for the formation of fungus on slopes and window sills, which negatively affects the functions of the human respiratory system.

Installation errors

1. Errors when making an assembly seam: incomplete foaming, which reduces heat transfer resistance; poor protection from external climatic influences, which leads to foam blowing or getting wet; absence or poor vapor barrier, which also leads to the insulation getting wet, but with steam from the side of the room.
2. “Cold bridge”, when, due to improper design of the junction unit, the window ends up in a cold, sometimes even negative temperature zone of the wall. This reason often occurs when heavy condensation appears.
3. Blowing through a wall structure, for example, a brick one, through empty seams - “empty space”. This phenomenon can be encountered in houses of the socialist period - the builders did not fill the vertical seams well. But this has also become a problem in new construction with multi-layer walls, when the mineral wool is covered on the outside with brick or other cladding. In this case, the insulation must be ventilated, and when the windows are placed in the plane of the insulation, they may be exposed to cold air from the side of the junction. In this case, during installation, it is better to separate the wall from the junction unit with a layer of foamed polyethylene 6-10 mm thick.
4. A wide window sill prevents the convection of warm air from the radiator in the window opening.

Therefore, we can give the following tips to eliminate the possibility of condensation:

• If, after all, condensation is a consequence of increased air humidity, then this cause must be eliminated due to the increased likelihood of mold appearing in the room.
• To reduce indoor air humidity and move the dew point to lower temperatures, we recommend installing a Regel-Air climate valve or ventilating the room for 10 minutes twice a day.
• Heat losses with such ventilation are insignificant even in winter and amount to no more than 3 degrees.
• The intensity of ventilation of the room must be increased during repair work.
• The window sill should not be very wide and prevent the passage of warm air.
• To allow warm air to pass through to the window, place the curtains at some distance from the window sill.
• Decorative screens on heating radiators should not interfere with the passage of heat flows from the radiators.
• It is necessary to periodically check the exhaust ventilation system in your home or apartment.

One of the most effective ways to combat condensation will be to install a window with a five-chamber Favorit system, developed by THYSSEN POLYMER GmbH (Germany) specifically for Russia.

The temperature on the inner surface of the profiles directly depends on the heat transfer resistance of the profile system. For example, we can consider two cases - at an external temperature of -26? C and at -31? C (at an internal temperature of +20? C and a relative humidity of 55%).

The dew point will be +10.7?C. Temperatures on the surfaces of a standard binding (three chambers and a width of about 60 mm) and a five-chamber binding with a heat transfer resistance of 0.78 m2? C/W will be as follows:

How to wipe windows to prevent sweating inside in winter

To eliminate condensation, you need to choose the right window demisting agent:

1. A wax candle is the most common folk remedy for normalizing the climate in a room. Place several candles on the windowsill so that they continue to burn all day and warm the glass. Due to air convection from the flame, condensation does not settle on the glass. As a result of the combustion procedure, carbon dioxide, which is beneficial for plants, is released, so the greens can be left on the windowsill. Pay particular attention to safety and remove items that could easily catch fire.
2. Soap . “Rub” a mesh with small cells on the glass with toilet soap. Smear the marks until shiny with a clean microfiber cloth.
3. Glycerin . Combine ethyl alcohol with glycerin until smooth in one container, based on the proportions 20/1. Pour the composition into a spray bottle and treat the glass. Polish any stains dry. When the processing is completed, the alcohol will evaporate, and a thin film of glycerin will remain on the glass for a long time.
4. Shaving foam . Squeeze a thin layer of foam or gel onto the glass, wipe with paper or a napkin until it shines.
5. Dry windows can be wiped with the pulp of half a cut lemon , after which the surface is treated dry with a towel.
6. Salt . A cloth bag filled with salt is placed between the doors. The grains will absorb excess moisture well.
7. Toothpaste . Apply toothpaste to a sponge or microfiber cloth and vigorously wipe the glass dry. You can also clean the surface with tooth powder.

Important! It is better to burn thick scented candles that burn for a long time and bring a touch of comfort to the interior of the room.

Anti-fog for cars

Automotive chemicals can be very useful around the house. Anti-foggers for windshields are as effective as folk remedies. They also last longer: on the outside of windows - 1-3 months, on the inside - until the next wash. In addition, they prevent icing, are easier to apply and have a long shelf life (from 2 to 5 years).

Names and cost of funds:

• VERYLUBE – 150 rub. (320 ml);
• Sonax – 300 rub. (300 ml);
• CarPlan – 300 rub. (250 ml);
• Sintec – 110 rub. (210 ml);
• ABRO – 200 rub. (103 ml);
• Eltrans – 110 rub. (210 ml).The method of application is the same as for folk remedies: you need to apply the composition to the glass and after some time rub the surface with a flannel cloth.

Rules for washing windows

Glass with a fatty layer can retain moisture for a long time. To get rid of smudges, you need to properly wash windows using alcohol degreasing.

Best washing methods:

• Wash the glass with soapy water or diluted dishwashing detergent. Wipe with a cotton napkin and remove white stains with a scraper with a rubberized nozzle. Apply alcohol to the sponge, treat the surface and allow the liquid to evaporate.
• A weak saline solution of 4 liters of water and 1 tbsp. l. Spread salt on clean glass. If white streaks appear, they need to be washed and the glass re-treated with a lighter composition.
• In a container, mix a thick mass of 40 ml of potassium oil, 4 g of pine turpentine and 20 g of glycerin. Rub the mixture onto the surface, spreading the mixture evenly over the glass with a sponge. Polish the window with a natural, lint-free cloth until it shines.
• You can rub the surface vigorously with crumpled newspapers, which have a water-repellent effect due to the printing ink.
• If mold has formed around the window due to moisture, it is necessary to remove it immediately and protect the room from reoccurring. You need to carefully go over the fungus with a bleach solution or vinegar to disinfect the surface. Apply a layer of primer on top. Allow the slopes to dry completely and repaint.

Armed and very dangerous... for dirt

When the question arises of what can be used to wash plastic windows, many begin to remember what unnecessary rags they have and what chemical mixtures have been hidden under the bathroom since the days of their mothers, fathers and grandparents. No need: pack it all up, throw it away and act like the professionals.

There are tools that you need to have at home both for everyday window care and for big seasonal tidying up. These include:

• window scrapers – regular and telescopic;
• sponges on the handle for cleaning windows with a microfiber attachment;
• a soft-bristled toothbrush – for windows only;
• spray;
• microfiber cloths;
• melamine sponge.

How to properly wash plastic windows without streaks?

Among the advantages of plastic windows is the ability to block noise and street dirt. At the same time, dust settles in an even layer on the double-glazed windows, and sooner or later everyone thinks about cleaning up. Cleaning and polishing glass perfectly is not an easy task. How to properly wash plastic windows without streaks?

Why do experts prefer microfiber? This modern material has several useful properties:

• does not fluff and does not dissolve into lint;
• absorbs moisture well and does not smear excess on the surface;
• does not leave streaks;
• The products wash well and serve like new.

Ventilation rules

Ventilation equipment is an effective solution to the problem of “crying” windows in an apartment.

Combs for windows

Causes of fogging

Serviceable PVC windows have a number of advantages (especially in comparison with wooden windows): they retain heat inside the apartment, do not let in extraneous sounds, protect from dust, and are not prone to icing. However, PVC windows have a limited resource for trouble-free existence.

Therefore, without proper regular maintenance, after a few years the structure will begin to leak through, allowing cold air to pass through, which will lead to the formation of condensation.

There are several reasons why windows sweat:

1. Unsuitable glass unit. Thermal insulation depends on the number of chambers in the frame: single-chamber double-glazed windows, for example, are not intended for installation in residential premises. And the only option to solve the problem is to replace them with two- or three-chamber windows.
2. Violation of natural ventilation. Installing a window sill that is too wide, or covering the radiator with a countertop, cabinet or screen without air access means blocking the movement of warm air. In winter, this leads to the dew point: hypothermia of the glass, the appearance of condensation on the windows.
3. Installation errors. If the team that installed the plastic windows foamed the cracks poorly, did the work in violation of the geometry, or did not adjust the connections, problems will not be long in coming.
4. Wear and loosening of structural elements. Worn rubber bands, loose hinges, locks and other fittings are another cause of microclimate disturbance.
5. Wrong mode selected. Modern models have summer, winter and universal mode settings. Summer differs from winter in that the sash is pressed weaker against the frame: if the windows fog up, check the trunnion.
6. Ventilation system malfunction. The windows were selected and installed correctly, but smudges are still visible on the surface of the glass? Check the operation of the hood in the room - probably the problem is poor outflow of stagnant air and inflow of outside air.

Important! Drops of water formed inside the glass unit are a sign of depressurization. The defective window must be replaced

If the windows in your apartment fog up a lot, you shouldn’t delay fixing the problem. The resulting high humidity, combined with low temperature, can lead to the formation of mold and mildew on walls and slopes, which will not be easy to get rid of.

Useful tips

To effectively combat the appearance of moisture on windows, you can use useful life hacks:

1. Installation of ventilation devices or double-action air conditioning to improve the ventilation process in the room.
2. If the humidity level is slightly exceeded, place air drying devices on window sills or nearby.
3. Using a hood when cooking: combating steam from cooking food will become much more effective.
4. Limiting activities that increase humidity: long baths, drying clothes indoors.
5. During renovation work, the relative humidity inside the room increases and the windows fog up. To prevent the problem, you need to isolate the window volume. Use construction tape to seal the opening with plastic film. Open the window sash slightly, and the moisture will settle on the film and not on the glass.

To prevent windows from freezing and mold around the frame, it is important to achieve the correct humidity and air circulation in the room.

How to fix?

As is clear from the previous section, the reasons for fogging of plastic windows can be different. Each of them requires an individual approach and has its own solutions.

The battery is covered with a tabletop, window sill, screen

According to the GOST standard, the window sill should not protrude beyond the radiator by more than 60 mm. If the tabletop is wider, it is necessary to cut ventilation holes in it, through which the flow of warm air from the heating devices will rise to the top.

Another way to improve circulation is a regular thick curtain. The fabric in front of the heating system device acts as a reflector, providing air flow to the cold window opening.

When using grilles to decorate batteries, make sure that they have ventilation holes not only in the front, but also on the top.

Defects resulting from violation of installation rules

The main rule of high-quality installation is to contact a trusted company with experienced craftsmen. Their work costs more, but savings in this matter can lead to additional costs in the form of re-ordering the highest quality double-glazed windows and reinstalling the window.

If the situation has already occurred and the plastic window is installed incorrectly, the only way to correct it is to contact a specialist. It is not recommended to correct errors on your own, because moisture on the surface of the glass unit is most likely only the tip of the iceberg.

Wear of fittings

When old windows that are more than 5-7 years old sweat, this is normal. The fittings of PVC structures have a limited service life: the more actively the window is used, the faster it wears out. In addition, operation in unsuitable conditions can lead to breakdowns: too severe frosts in winter, dry summers, etc.

The main problems arise from the rubber bands: worn seals allow fresh air to pass through and lead to the dew point. The replacement process can be entrusted to a professional, or carried out independently - the necessary materials are sold in any construction supermarket.

How to check that the pressure is insufficient: open the window, insert a sheet of paper, close the window tightly. The easier it is to pull a sheet out of a closed window, the worse the sash is pressed to the frame.

The mode does not correspond to the weather outside

The choice of mode is a controversial issue. On the one hand, the correct relationship with temperature helps to extend the service life of the sealing gum: in the summer it experiences minimal pressure. On the other hand, in the winter the windows are 100% sealed, which won’t hurt in the summer either: but the rubber is under increased pressure, so you’ll have to change it more often.

Therefore, in order to ensure the correct microclimate and extend the service life of the fittings, experts recommend changing the mode with the changing seasons. For this:

1. Open the window sash.
2. Find the eccentric on the inside (the so-called trunnion, a photo of what it looks like is below).
3. Turn to the desired position depending on the fitting option.

Types of eccentrics:

• Oval trunnion: standing vertically - summer mode, horizontally - winter, diagonally - average value.
• Round eccentric: the point or mark is directed inside the room - winter, outside - summer, in the center - universal.

Important! The high level of pressure should be short-lived - maximum 2-3 months

Ventilation does not work

The easiest way to solve this problem is simple ventilation. If you find droplets on the glass, open the sash completely for 5-10 minutes. The air humidity will become lower, the air temperature will level out and the water from the glass will disappear by itself.

If the windows in the kitchen sweat during cooking, and you can’t ventilate and cook at the same time, turn on the forced hood.

A more correct and “advanced” option is to use supply valves designed specifically for delicate “blowing.”

Getting rid of moisture

This method is suitable if you do not have the opportunity to carry out the above procedures. It is about eliminating the consequences, not the causes.

To work, we need an adsorbent - a special product with a sorbing effect. Sold in construction stores.

1. We attach tape to the bottom of the problematic frame.
2. Pour desiccant into the resulting pocket.

As they become saturated with moisture, the balls will change color and will need to be replaced.

Regular soap

If anyone doesn't believe it, try applying it to the windows. This is an old, ancient method that has been working for years (by the way, soldiers used it to treat the glass in gas masks so that they would not sweat).

The principle of application is simple. You need to apply the “mesh” with a bar of soap to the car windows and then rub it well. The composition works reliably, the efficiency is HIGH.

There are also disadvantages - you can only do this in warm weather, because it is VERY difficult to grind such a mesh in the cold

Means for treating foggy glass

To solve the problem of fogging, the automotive industry produces various glass treatment products. They are called anti-fog and anti-rain. They come in the form of aerosols or liquids and are sold in auto chemical stores at an average, affordable price.

Almost any car window defogger is alcohol-based. This is a fairly reliable product that reduces the amount of condensation on the glass and improves visibility during rain. However, there are situations when there is no ready-made anti-fog agent, but you need to go. It’s raining outside, 5 people are sitting in a car, and condensation is constantly forming on the windows. What home remedies can replace auto chemicals?

WD – handy auto chemicals

If an anti-fog agent is a special substance that needs to be bought at a car store, then WD is a rust remover liquid, which is often stored in a car enthusiast’s garage and is used for various purposes. You can also treat glass with WD solvent to prevent it from sweating.

Shaving foam or gel

Personally, I myself use this method and I think that this is the best do-it-yourself anti-fog for the money. And the most important thing is that both are available in almost every home and there is no need to spend extra money on purpose.

Application method - you will need paper towels (gel works better, not much, but still). Squeeze out a little and rub the glass. Next, take a dry towel and treat the surface until transparent.

The efficiency is the highest. Almost no cons

Now watch the video version

In conclusion, I would like to say that these anti-fog recipes will of course help you, but if it’s damp on your rugs and especially under them, you can squeeze it out, then you need to first dry the interior and then treat it, otherwise the effect will be much worse.

You can also advise putting some cat litter in a small bag, say under the seat, it will absorb excess moisture and keep it inside. You need to change it about once a week or two (it will simply swell).

Why is condensation dangerous?

If plastic structures begin to fog up, it may seem unpleasant, but it is harmless. In reality, everything is not quite like that. Excess moisture spreads from the glass to the window sill, walls, and ceiling. In such conditions, fungi and microorganisms thrive very well, including many that are dangerous to humans. In a warm, humid environment, they quickly multiply and “spread” around the room.

Allergy sufferers and people with respiratory diseases will feel especially bad in such conditions. But that is not all. Damp construction and finishing materials swell and begin to collapse. Sometimes this process goes very quickly; after just a few months, a good repair becomes unusable.

Cleaning Caring for plastic windows: 7 things no one does

Traditional methods

As already mentioned, the reason why plastic windows fog up is high humidity. Accordingly, to solve the problem you need to get rid of it. It is necessary to act consistently. For example, when cooking, and especially boiling, you should use a hood so that all excess moisture comes out immediately. Also, do not let the kettle boil for too long, releasing clouds of steam.

Using a hood in the kitchen prevents the accumulation of excess moisture in the house

If the windows are already fogged up, you can dry them by pointing a fan at them. Another, even more affordable option is a pair of burning candles that are placed on the windowsill. Not only will they be able to dry the entire window opening, but they will also release carbon dioxide, which plants like so much.

To properly direct air flow, convection screens can be made to direct heat from the radiators to the windows. They are made at an angle to the battery and disguised as all sorts of beautiful decorative elements.

It remains to note one of the most interesting and at the same time radical methods. Everyone knows that the best defense is attack, so this methodology involves turning cold windows into a full-fledged heating element. First you need to glue a nichrome thread, foil or conductive film around the perimeter of the glass, through which you need to apply a voltage of 24 volts. Today you can buy materials at almost any hardware store. True, before installation it is better to once again consult with a specialist.

Installation of double-glazed windows with electric heating

And finally, a very simple, effective and not at all expensive way to get rid of fogging is to create an additional chamber by installing a transparent PET sheet. Anyone can perform this procedure after watching this video:

It is worth understanding that foggy windows are not the norm. They indicate excessive humidity, which in turn has an extremely negative effect on the inhabitants of the house. The problem itself can be solved quite simply, you just need to devote a little time to it.

Causes of moisture on windows

Some people believe that fogging of windows in the house is a completely normal phenomenon that appears over time. However, if this condition occurs periodically and repeatedly, it is necessary to establish the cause of fogging and find a way to eliminate it.

You should not blame the window manufacturer or their installers, although in most cases, according to statistics, the share of their errors is 4% of the total number of deficiencies, since the rest appear due to non-compliance with the rules for using the products.

The reasons for the appearance of condensation on glass may be:

• installation of cheap single-chamber double-glazed windows in order to save money;
• obstructed air circulation due to a blocked radiator under the window; to restore circulation, the width of the window sill should be made smaller;
• poor ventilation of the room or its absence at all, in this case cleaning the air ducts will help;
• vegetation placed on the windowsill with air humidification properties;
• improper installation of windows.

First, it’s worth figuring out why high-quality windows sweat when they are installed in accordance with all the rules, as shown in the photo. Basically, double-glazed windows fog up in winter.

But not only cheap double-glazed windows fog up; this applies to more expensive and high-quality models. All plastic windows are quite sealed and do not let air through, which can be attributed to both the pros and cons of the product. Those. heat leaves the room slowly and if you do not ventilate the room regularly, condensation will certainly form.

In addition, without proper ventilation of the room, the atmosphere in it will become unfavorable for people and plants, which will lead to the proliferation of viruses and the occurrence of diseases.
