Additional window insulation. How to insulate plastic windows for the winter. Do-it-yourself step-by-step instructions for warming with your own hands

Now many people are replacing wooden windows with plastic ones. However, during operation, their tightness may be violated. The question arises before people how to insulate plastic windows so that the violation of integrity is corrected, and the air from the street penetrates less into the room. It is important to understand what is the cause of the problem and solve it, and then make an isolation.

Why is it blowing from plastic windows

Before you begin to correct the current situation, you should find out why the blowing occurs, whether there is fogging. There are many reasons, but there are several main ones:

Marriage in production.
For the manufacture of windows, low-quality plastic was used.
Bad fittings were installed.
Mistakes were made during installation.
Poor quality seal material.
The slopes were not properly insulated.

How to determine the cause

First, let's make sure that it's definitely blowing from the window. To understand this, you can bring a lit candle or lighter to the joint casement and frames. If the flame fluctuates, it means that it is blowing from the window. Then the candle should be held around the entire perimeter. The problem often occurs at the junction window frame and slope. This indicates poor installation, so you need to contact the company and demand to fix the work (if the warranty period has not expired).

The reason may lie in the incorrect adjustment of the fittings or in the lack of installation for winter mode. To do this, try to open the window and look at the lock. Not everyone can independently determine the problem and make settings, so it’s better to call the wizard. Sometimes the reason is in violation of the window geometry. In this case, there is a poor clamping of the sashes, due to such an abutment, drafts occur. Will need a complete re-installation of the double-glazed window.

Another way to diagnose is to check the condition of the seal. It probably causes moisture to blow or leak (condensate forms) if it is of poor quality or heavily soiled (remove all dust). Under the influence of low temperature, it loses its elasticity. You should touch it with your hands, checking for elasticity. If the reason is the wear of the insulation, then it needs to be replaced.

The next step is to pay attention to the quality of the plastic. Unfortunately, an ordinary person will not be able to visually distinguish high-quality plastic from bad, this requires a specialist. However, if all of the above diagnostic methods did not reveal the cause, then most likely you bought windows from poor material. We'll have to dismantle and install a new metal-plastic structure.

When is the best time to insulate?

The problem of blowing windows occurs during the cold season. In the summer, people either do not notice this, and with the onset of cold weather, the air from the street becomes noticeable. It is best to do thermal insulation in spring or summer in calm weather.. The sealing composition requires a special temperature, it can not be used in winter weather. There is a plus of warming in the cold season: it is clear which place to insulate and whether the chosen method is effective.

How to insulate plastic windows

It is extremely important to understand how to insulate plastic windows. There are many ways of thermal insulation, so each person can choose the most convenient for himself. Insulation for plastic windows is as follows:

Polyurethane foam - fast and available method. However, the foam is short-lived, it is adversely affected by temperature changes, ultraviolet radiation, air.
Mineral wool is a safe and fire-resistant modern material.
Window film is good to use as insulation for the glass itself.
Silicone sealant is reliable, while inexpensive.
Styrofoam is used to eliminate gaps in window slopes.
Warm mixtures are applied outside.
Glue construction tape over the sealant, which will improve the effect.
Facade paint has a high weather resistance. It is easy to apply to any surface.
The primer dries quickly and is easy to apply. She is frost-resistant, she is not afraid of moisture.

When You Can't Do Without a Master

A professional is needed when there are obvious defects, and work to eliminate them requires compliance with safety regulations. To carry out repairs, it is worth calling the master, because:

insulation of slopes and ebbs from the outside can be dangerous, especially if the window is higher than the second floor (you can fall and break);
to properly insulate, it is important to know the whole technological process installations;
the window is still under warranty.

Do-it-yourself insulation of plastic windows for the winter

How to seal plastic windows for the winter, a professional will advise. However, there are simple and easy ways by which you can make repairs yourself. A simple example is the thermal insulation of a window using foam or sealant:

Delete old foam from all the holes around the window. To do this, use a hard brush, sticks and brushes.
Thoroughly rinse and wipe the surface of the window sill and slopes with a cleaner to degrease and eliminate dust.
Cover the resulting cracks with putty and plaster, then fill with mounting foam.
If a sealant is used instead polyurethane foam, then after its introduction into the slot, it should be glued on top with construction tape. To carry out work, a knife and scissors should be at hand.
Install heat-saving film. The window box is cleaned of dust and pasted over with double-sided tape. The film is measured to the size of the window, then carefully applied and smoothed. To avoid bumps and bubbles, you need to blow it with a hairdryer.

Outside

You can make insulation from the side of the street in different ways, suitable facade paint, primer, silicone sealant. It is best to use foam plastic for thermal insulation of slopes from the outside:

Styrofoam right size it is necessary to stick on the slopes, and close all visible cracks with glue.
A special mesh should be placed on top of the foam, and then plastered.
Align the plaster with a water-repellent layer, apply a primer.
Paint the resulting slopes, which will create an additional energy-saving protective layer from the wind.

Inside

Insulation of plastic windows inside must be done as carefully as possible, using for this different ways. Thermal insulation will contain the following steps:

Insulate the slopes of plastic windows inside. To do this, apply mounting foam.
Put plastic on top of the foamed slopes.
Adjust fittings. This is done with the help of an eccentric by means of rotation.
Replace seal. This element must be changed every 5 years. During this period, it loses elasticity and begins to pass air.

How to insulate the window sill of a plastic window

You can often feel the movement of cold air under the windowsill. If the crack is visible, then it needs to be foamed. It will be good if you attach a piece of plastic under it, and fill the void inside with polyurethane foam or foam. Stages of window sill insulation:

Remove window sill.
The wall on which it was located should be well cleaned of dirt and dust, after which all cracks and problem areas will be visible.
Cracks can be closed with mounting foam.
When the foam hardens, cut off the excess with a knife.
Prime the entire surface.
Apply sealant to all joints and corners.
Plaster.
Install the window sill.

Warmth in a house or apartment is a guarantee of comfort, coziness and well-being. To do this, we spend in our apartments central heating, we construct heat-insulated floors and other. However, it is important not only to deliver heat to the house, but also to keep it.

Most of the heat leaves our apartments through the windows, insulating which can significantly improve your living conditions in the cold season.

let's consider quick ways insulation, both modern plastic windows and old wooden ones. Let's start with the simplest and cheapest ...

1. Do you want to insulate the window? - Wash it!

Heat leaves our apartments not only because of drafts, but also goes outside in the form of infrared radiation.

Ordinary glass, being transparent to the radiation of the visible spectrum, has low level transparency for infrared rays that transmit heat.

But contaminated glass, losing transparency in the visible part of the spectrum, significantly increases it in the infrared spectrum. Therefore, to save heat, it is enough just to wash the window before the start of the cold season.

However, in the spring it also does not hurt to do this - so that less radiant heat penetrates the apartment in an already hot summer.

Wash the window inside and (required!) Outside with an ethyl or ammonia. This will allow, firstly, to clean fatty contaminants, which is especially important for the kitchen, and, secondly, to avoid stains left by salt dissolved in water, which remains after evaporation of moisture.

In addition to the glass, the frames also need to be washed - we will glue seals, heaters and so on on them. Doesn't adhere well to dirt, but falls off quickly. You do not want to re-glue the seal in the middle of winter with the windows wide open?

2. Traditional methods of window insulation

Effective way To reduce heat loss is to install a heat-shrinkable energy-saving film on the inside of the frame, parallel to the glass or double-glazed window.

This film has a double action. First, it prevents heat from escaping in the form of infrared radiation. Secondly, it creates an additional heat-insulating layer of air between itself and the glass. This usually gets rid of the " weeping windows».

Installing the thermal film is quite simple. On the frame, having previously cleaned and degreased it, we glue double-sided tape around the glass. The film is usually sold folded in two layers. We separate the layers among ourselves and cut the film according to the size of the glass, plus two or three centimeters from each edge.

We glue the film on the adhesive tape so that its surface covers all the glass. We try to stretch the film, but we do not pay attention to wrinkles. It is more important to ensure that the entire edge of the film "sits down" tightly on the adhesive tape without "bubbles". We direct hot air from a household hair dryer onto the film. Due to its shrink properties, the film itself will stretch and smooth out.

The view at the window with such a film, of course, is not so hot, for it is warm and dry.

New double-glazed windows do not heat. Why?

Similarly, the seal on the frame changes, after which the sash is installed in place.

Procedure for installing the sash reverse order when removing:

The sash is mounted from top to bottom on the bottom hinge, then the parts of the top hinge are connected by moving away from itself, the pin, lock washer and hinge overlay are installed. We close the sash with a lock and check the quality of the work performed, testing the joint for a draft.

In order for the seal on the plastic window not to have to be changed every two to three years, this part requires proper care. It is required to clean and lubricate the seal at least once a year, but preferably twice, before the start of the cold season and at its end.

We wipe the seal on the sash and frame with a dry fleecy cloth to clean the accumulated "rel="lightbox" href="/images/stories/kvartira/7-sposobov-uteplit-okna-na-zimu_8.jpg"> mud. Then wipe the seal with soapy water to better cleaning and degreasing and wipe it dry. We apply silicone grease to the cloth (it can be purchased at any car dealer) and rub it into the seal. This simple procedure will protect the sealant from drying out in the heat and “hardening” in the cold, allowing it to retain its qualities for a long time.

6. We insulate slopes and window sills

For some reason, some people forget that a window is not only glass, a frame and sashes, but also slopes and window sills. What's the point, from the very the best window, if from under the windowsill in full "siphon"? Of course, it is better if, along with the replacement of the window, you also replaced the slopes and window sills with modern PVC structures, however, it is precisely when installing them that the installers often “hack”, knowing that the customer will pay the main attention to the frames.

Inspect the places where the slopes adhere to the concrete. If large cracks are found, we fill them with tow or foam rubber and cover them with alabaster on top, or fill them with mounting foam, which will need to be trimmed and sanded with sandpaper after drying. We complete the sealing of cracks with construction sealant.

If the initial examination reveals nothing, conduct a more thorough test with a burning match or a wet finger. If "cold bridges" are found, it is necessary to "knock" the cladding layer. Deaf compared to neighboring plots the sound will indicate the presence of voids under the lining layer. In this case, we remove the cladding and seal the cracks in the manner described above. Do it really" rel="lightbox" href="/images/stories/kvartira/7-sposobov-uteplit-okna-na-zimu_9.jpg"> , follows in the warm season, because mounting foam and finishing building mixtures do not work well in the cold.

You can also make slopes yourself from inexpensive improvised materials, for example, from foam, while saving on PVC slopes and the services of installers. To do this, you will need foam panels at least three centimeters thick, foam glue (for example, "ceresite") and cement mortar.

This work, however, is not the easiest, fastest and cleanest. It is worth thinking twice about whether it would be better to invite a professional. But if you decide for yourself, then in short you will find the following:

The sides of the window opening and part of the adjacent wall should be opened to the base - brick or concrete. This is done in order to drown a layer of insulation into the wall. Here you can expect a lot of surprises, in the form of boards immured by the builders, rolls of tow and other "insulations". The holes will be impressive. There may even be a fair amount of plaster on the adjacent wall falling off, so get ready for a plaster job of the appropriate scale. To ensure reliable adhesion of the future slope to the base, you can fix the reinforcing network with dowels (plastic - so that it does not conduct cold).

After kneading the cement mortar, we apply a layer of plaster on the window opening and on the wall, to the width of the future slope (about 20 cm) from the opening. Clay can be added to the solution. This will give it additional viscosity, and it will be easier to plaster the vertical surface of the walls. We achieve a flat surface and let the plaster dry well.

However, if you are confident in the reliability of the existing layer of plaster, then you can simply carefully scrape off the wallpaper, paint or other decorative coating walls, primed and leveled with a small layer of surface putty.

"rel="lightbox" href="/images/stories/kvartira/7-sposobov-uteplit-okna-na-zimu_10.jpg"> Next, on the foam panels notched trowel apply glue and press the panel to the surface, holding for 10-20 seconds until the glue “sets”. First, we glue the foam to the vertical part of the wall and slopes. The seams between the panels are carefully covered with the same glue. Similarly, we install panels on the horizontal part of the slope in window opening.

Alternatively, foam can be used. It fills the voids in the slopes well, holds firmly to the base, and the insulation itself can be securely “glued” with it. Here, only, it is a little expensive, but you need a lot of it (a large balloon for a double-leaf window may not be enough).

You can close the foam plastic with drywall, or thin plastic panels, putting them again on the glue.

I repeat, the surfaces are complex, there are many angles. Professionals use other heaters and install special cladding panels. But if you need to save money or want to do everything yourself - you can try it.

7. Window insulation using Swedish technology

If the installation modern window from a PVC profile you can’t afford, or it’s not suitable for any other reason, insulate the usual wooden window It is possible according to the newfangled Swedish technology. Such a sonorous name was given to the technology of window insulation using the Euro-strip groove seal, Swedish-made, although analogues made in Eastern Europe have already appeared on the market.

The technology requires the use of a rather specific tool, which not everyone can find. home master, and experience of handling it is needed. So for this service it is better to turn to 7 ways to insulate windows for the winter: Photo 11 "rel="lightbox" href="/images/stories/kvartira/7-sposobov-uteplit-okna-na-zimu_11.jpg"> specialists. But all work is done quickly, so the method is quite suitable if winter "suddenly crept up unnoticed."

To install the seal, the window sash must be removed. In the place where the sash fits to the frame, a groove is made with a cutter, where a tubular profile is placed with a special roller, which takes the form of a groove. Additionally, the connection is sealed silicone sealant. If desired, insulation with Swedish profile can be done inside a double frame. The balcony door is similarly insulated.

7 ways to insulate windows for the winter: Photo 12" rel="lightbox" href="/images/stories/kvartira/7-sposobov-uteplit-okna-na-zimu_12.jpg"> "Swedish technology" also includes the fitting of sashes, frames and balcony doors, however, this must be done in any case, regardless of the installation of Swedish seals.

The effectiveness of such insulation is slightly better than traditional sealing, but it allows you to freely open windows and vents during the winter for ventilation.

We examined the most common ways to insulate windows that do not require major repairs. I hope our tips will help add some warmth to your life.

We installed or moved into the house with existing plastic windows. We believe that the issue of reliable thermal insulation window openings We won't have to return to our home. Alas, it is not.

The question of how to insulate a plastic window may become relevant again. Perhaps after installing window structures will pass there is not even enough time to solve it.

Of course, companies that produce and install windows give them their warranty period. We have the right, before its completion, to make claims to them and demand the promised thermal insulation properties of the window. But, and the warranty period once ends.

It also happens that residents of regions with winter temperatures below minus 30 want to improve the thermal insulation properties of installed plastic windows. Such an option is possible. And for this there are appropriate materials.

Selection of PVC windows, control over their installation

We solve the issue of reliability and quality of the thermal insulation properties of window openings on our own even at the stage of making a decision on the installation of plastic windows.

If we ourselves do not have experience, skills in installing PVC windows, then we must responsibly approach the options:

Which company to entrust the installation of plastic window structures.
Windows and accessories, which manufacturer we will install.
Profile type, how many choose air chambers in it (three cameras is optimal, but more is possible).
What type of double-glazed window will we order (for better thermal insulation select energy saving). We choose its width, the number of chambers, the sealant, what the chambers between the glasses will be filled with, what coating will be applied to them.

How to make this choice? Contact the experts, get acquainted with the design of plastic windows, with products from different manufacturers, with the offers of window construction installers, with the documentation for PVC windows.

It is useful to familiarize yourself with GOSTs for PVC windows and their installation:

GOST 26602.1-1999 Heat transfer.
GOST 26602.2-1999 Air - and water permeability.
GOST 26602.3-1999 Sound insulation.
GOST 26602.4-1999 Light transmission.
GOST 26602.5-2001 Wind load resistance.
GOST 30673-1999 PVC profiles.
GOST 30674-1999 PVC profile blocks.
GOST 30971-2002 Mounting seams.
GOST 52749-2007-8922 PSUL.

Decide on the questions above. The next step is to carefully control the process of installing plastic windows. What would we quality windows did not choose, it is from their professional installation that 90 percent depends on the warmth and comfort in your home.

The right technology and detailed instructions competent installation of PVC windows are established by regulatory documents.

It does not hurt, before controlling the actions of window installers, you will familiarize yourself with them, these are:

the main "mounting" GOST 30971 - 2002 "Seams assembly units adjoining window blocks to wall openings. General technical conditions".
SNiP 23 - 02 - 2003. " Thermal protection buildings."

Important! We must insist that the contract with the company that installs PVC windows for us includes the requirement for their installation in accordance with the above GOST.

Before installation, check:

How the window opening is prepared for the installation of a plastic window. We check the vertical slope, horizontal level with a liquid level.
What are the dimensions of the gaps left between the wall and the frame of the double-glazed window. Gaps should not exceed the length matchbox(not more than 5 cm), but not less than 15 mm. A gap of less than 15 mm will be problematic to evenly and reliably fill with foam insulation.

During installation, we control:

In order for the mounting seams between the window and the wall to be performed with high quality, and along their entire perimeter, according to the principle “tighter from the inside than from the outside” in three layers of sealing:

from the street - climate protection;
inside - a heater;
from the side of housing - vapor barrier protection.

How tightly and completely window installers fill these gaps with mounting foam.

Pay special attention to the fact that the gaps are filled with high-quality mounting foam. This polyurethane foams, foam - specially designed for installing windows.

Make sure that slopes and window sills are properly and reliably insulated.

Useful advice! Do not spare the money to establish external slopes. They will help the mounting foam retain its properties as a heater longer.

Insulation of window structures and glazed loggias

But, even with the correct observance of the technology for installing PVC windows, there is a need for their insulation to winter period. Or maybe you moved into a new building, where PVC window structures were installed en masse, with a poor-quality fit.

Revision and control of windows readiness for winter

Before deciding how to insulate plastic windows with your own hands before the onset of cold weather, we first revise them?

First you need to identify the very presence of air leakage through the plastic window structure. Determine in which node, in which place of the structure there is such a leak. You can decide here by the behavior of the flame of the lighter when you hold it around the perimeter of the window or simply with the help of your hand.

Note! Before winter, do not forget to move the summer-winter adjustment mechanism to the maximum protection position.

Replacement of glazing beads, seals.

If an air passage is detected near the double-glazed window due to a problematic glazing bead (lining), with which the double-glazed window itself is fixed, then we change it:

using a narrow spatula, pry and pull out the old glazing bead;
using a rubber mallet, lightly tapping, install a new glazing bead.

Visual representation of lining replacement

If necessary, we replace the seal itself, which has lost its elasticity, between the double-glazed window and the frame:

Remove the glazing beads (you need to start with the side plates).
Remove the double-glazed window by first pulling out the lining.
Remove the old seal tape.
Cut off the new seal tape equal to the length old (preferably with a margin of 3 - 5 cm).
Carefully, without compression and tension, lay a whole tape of a new sealant, cut off the excess piece with scissors.
Reinstall the double-glazed window, linings, glazing beads.

If air leaks are found near the frame, then the problem is with the clamping elements. In this case, the possible reasons are:

the sash is weakly pressed (with a hex key, which is used to assemble furniture, or a screwdriver with an appropriate nozzle, pliers on the open sash in the hole on the side of the handle and hinges, press the sash more tightly against the base);
poorly fitted seals around the perimeter of the frame and sash:

Remove the old seal;
Clear the place of its bookmark from possible debris;
Lay a solid strip of new sealant into the groove of the sash and frame (the length of the extension must exactly match the length of the groove);
We glue the new laid sealant.

Note! Try to buy new seals from the manufacturers or installers of your windows. When cleaning the profile surfaces where you will lay the profile, use PVC cleaners.

Do not forget to take care of the installed seals, wipe with a sponge with warm soapy water, lubricate with glycerin or silicone oil.

When preparing housing for winter, the question arises, how to insulate metal-plastic windows additionally? How to improve the thermal insulation properties of the glass unit itself? And most importantly, how to insulate plastic windows?

These issues are easily resolved. We insulate PVC windows with heat-saving PVI -. During production, its surface is covered with a special metal coating.

Such a coating reflects infrared rays, effectively preventing heat loss from living rooms. Insulation of the loggia (balcony), which are glazed window systems PVC, can also be effectively solved with the help of such a film "glass insulation".

Film - an option on the way to warmth

A good choice, protection and insulation for plastic windows is a heat-saving window ceramic IR film (for example, KorQu models of the PREMIUM IR 6070 and IR 6560 series).

And, in combination with a warm floor in the rooms and on the loggia, such film insulation for plastic windows will create an even greater effect in winter, because such films will reflect the heat of the warm floors towards its source, i.e. back to the rooms and the glazed loggia.

This method of insulating PVC windows in living rooms and balconies inexpensive. And the price, when heat losses are reduced to 60 percent, is no longer so important.

Installing such a film on double-glazed windows of plastic windows is a simple process. It is simply glued to the glass itself and smoothed out. For convenience, you can use a plastic wallpaper spatula.

How to insulate plastic windows using heat-saving film:

Preparing windows (we clean, wipe with a wet sponge).
We prepare the film (after removing the protective layer, we wet it).
We wet the glass.
We stick and level the film, using a plastic spatula, on a double-glazed window.
Cut off the excess part of the film with a cutter.

Replacement of the mounting seam, installation of insulated slopes and window sills

Over time, you have to look for the answer to the question of how to insulate plastic windows from the outside. It is bad if you did not install external slopes in time, which should protect the heat-insulating layer of mounting foam from natural phenomena, did not insulate them.

Then the foam, as a heater, will serve its time faster, will begin to lag behind the wall, the drafts that have appeared will transfer the “dew” point to the internal slopes.

If it is necessary to repair the foam heat-insulating layer and its climatic protection, we perform the following actions:

We remove the old foam from the gap between the window and the wall (you can use a chisel).
We spray the gap with water (so that the mounting foam sets better after).
Fill this gap with new foam.
To protect the foam, cover the gaps with a sealant (for example, acrylic sealant Belinka, Dymonic NT polyurethane sealant).
We install external insulated slopes. As a heater, you can use foamed polystyrene foam (polystyrene, sizes 2 cm or more), mineral wool, EPS (extruded polystyrene foam). Some use ready-made insulated pvc slope, having bought it in stores like Maksidom. It is a plastic, dimensions 2200x300x10 (mm), filled with extruded polystyrene.
We do an inspection of the window sill. If necessary, insulate the window sill.

How to insulate the window sill of PVC windows?

The window sill can be insulated with polystyrene foam (expanded polystyrene foam).

Cut out the styrofoam to the desired size.
We grab it with mounting foam.
We lay a window sill on top of the foam.

Important! Do not fasten the window sill with self-tapping screws to the plastic window. Use pads to secure it.

Reading time ≈ 9 minutes

Plastic double-glazed windows are considered one of the most hermetic types of home windows, but even they begin to let cold air into the house over time. In this article, we will look at how you can insulate plastic windows for the winter indoors with your own hands. This will increase the indoor temperature by a few degrees and save a tidy sum on heating.

Determination of places of draft

For effective insulation windows, it is necessary to find and eliminate the cause of the draft. Otherwise, all procedures aimed at warming will not give the desired effect. To find problem areas, you need to independently check all the critical nodes of the window:

Glass holders.
Sealant.
Loops and handles.
The junction of slopes, walls and window sills with window frame.

Appearance technical faults in one of these places can lead to the appearance of drafts, which in cold weather has a very strong effect on the temperature inside the room.

To determine the exact location of a heat leak, the following methods are used:

Causes of drafts

You should also have basic information about the causes of drafts. With basic knowledge, you can avoid such unpleasant situations in the future.

If we evaluate in detail all the causes of drafts and heat leaks, we can divide them into two categories, if possible, to eliminate them - with the help of window installation wizards and independent decision problems.

The services of professionals are best used to solve such problems:

If the work is done from the inside, then most of them can be done independently.

Plastic window insulation

Depending on the identified place of heat leakage, the work carried out will be different. Let's consider each direction in more detail, and also determine how to insulate plastic windows for the winter.

Slope insulation

If a draft was found in the gaps between the window frame and the wall, then poor thermal insulation should be considered the cause of this phenomenon. It could become unusable from time to time, or there were violations of technology during the installation process.

The most correct would be a complete installation of thermal insulation materials again. To do this, remove the slopes and do the following:

If the cold has already come, and there is no way to spend complete replacement thermal insulation materials, then you can take temporary measures and treat the cracks with sealant. This will save for some time from the penetration of cold into the house, but in the future it will be necessary to carry out a more thorough reconstruction.

Important! Many sealants have a clear temperature range in which they can be used. Violation temperature regime can affect the main qualities of the composition. Be sure to check the possibility of using sealant.

window sill insulation

In case of loss of tightness in the area of the window sill, it is necessary to accurately determine the location of the leak.

Such events will be enough to insulate the window sill and eliminate any drafts in these places.

Warming by adjusting windows

The reason for the appearance of drafts may be insufficiently tight fit of the locking elements to each other. To eliminate this, you need to know the basic principles of operation of plastic window sashes.

If the windows were initially installed correctly and closed tightly enough, then the problem can be eliminated by slightly shifting the sash. How to adjust the window at home on your own is described in detail in this video:

The windows of most brands have a system for switching to winter or summer mode. To determine in what position the windows are now, you need to pay attention to the locking pins. Depending on the manufacturer of windows, they mark the current state of the window. If the mark is turned inside the room, then the windows are in the "summer" mode, and in winter mode if the trunnion is turned in the opposite direction.

When the window is set to summer mode in the closed state, the sash does not fit snugly against the frame. This allows you to maintain micro-ventilation in the premises.

In winter, such ventilation is more of a problem than good, so the window needs to be switched to winter mode. To do this, turn all the trunnions into the desired position.

The middle state is a balance between micro-ventilation and heat retention. It is also called spring or autumn mode.

Important! Windows in winter mode are designed for maximum pressing of the sash to the frame, which means that fogging of the glasses will be almost guaranteed. To avoid the appearance of fungus, it is necessary to regularly ventilate the room even in winter days.

Replacing the sealing material

Another way to insulate plastic windows for the winter with your own hands inside is to replace the sealing gum between the window frame and the opening sashes.

Important! It is worth replacing the seal only if it has become unusable. With regular care and treatment with softening compounds, it can last more than 5-8 years without losing its qualities.

First you need to determine whether the seal is to be replaced. If you are a happy owner of a window with a replaceable rubber seal, then you can proceed to the next steps.

You can familiarize yourself with the procedure for replacing the seal in detail using the example of one of the installation companies:

Attention! If you are not sure about the correctness of the above work, and also doubt the own forces We recommend that you seek professional help. Most plastic window installation companies can do additional customization and minor restoration work for a fee.

Warming with additional means

Sometimes a plastic window is in perfect order and does not create drafts, but in itself is a place of heat loss. In this case, it must be insulated with additional means. Consider a few simple ways additional insulation window.

The use of improvised means used for, in the case of correctly installed and configured double-glazed windows, shows minimal efficiency. Their main purpose - the elimination of drafts, does not work with hermetically sealed plastic windows.

Now you know how you can insulate plastic windows for the winter in your house and you can put most of the methods into practice. Also remember that windows are not the only place where heat is lost. It will be possible to get maximum heat retention after and..

Over time, even PVC windows begin to lose their tightness. Therefore, in the conditions of Russian winters, they need additional protection and adjustment. In this article, we will consider how to insulate plastic windows for the winter with our own hands.

Before you insulate windows with your own hands, you should identify "problem" places. Metal-plastic structures over time or with improper installation can begin to let cold air through. In winter, this is most noticeable, so it is easier to identify the reasons for the influx of cold air at this time of the year.

Cold air can enter the room through:

Accessories.
Places where the frames fit to the slopes, wall or window sill.
Rubber seal (between frame and glass).
Fixing pad ("glazing bead").

You can determine where the gap is located in the old proven way: we take a lighter (simple gas) and bring it to all of the above elements. The flame will begin to oscillate as air leaks. The main thing is not to bring too close to the frames, so as not to melt the plastic.

Main front of work

Do-it-yourself preparation of plastic windows for winter includes the replacement of elements that have failed. Many Russian manufacturers don't spoil high quality consumables (seals, etc.). Therefore, they regularly have to be changed in order to block cold air from entering the apartment.

We replace the glazing bead

If an air leak is found around the glazing bead, it must be replaced. This is done very simply:

With a narrow spatula (in extreme cases, a knife), we pry the glazing bead and carefully pull it out.
We get a new one. You need to choose it according to the size of the window.
We put the glazing bead in place of the old one and with a rubber mallet, we drive it in with light taps.

The cost of this element is low - within 100-200 rubles, but it depends on it whether street air enters the room.

Replacing the fixing pad

The lining loses its elasticity during operation. This is primarily due to temperature fluctuations. The replacement is as follows:

We remove the glazing beads (first the side ones).
Take out the pads.
We dismantle the glass.
We remove the old tape.
Cut out a new one. In this case, a margin of several centimeters should be made.
Laying out a new tape. No effort is needed.
We collect all the dismantled elements.

We fix leaks in the frame area

If there are leaks in the area of \u200b\u200bthe frames, then the problem lies in the clamping elements. There are two possible reasons.

The sash is badly pressed. To fix this, use a hex wrench (or a screwdriver with an appropriate nozzle) to tighten the sashes more tightly. Simply insert the hexagon into the appropriate slots and scroll until the frame is properly pressed.
The seal is of poor quality. In this case, we proceed as follows:

Remove the old sealant.
We clean the place of its installation from all kinds of debris.

Tip: If there are adhesive residues or other stubborn dirt, use a special PVC surface cleaner.

We lay the strip of sealant in the appropriate grooves. The length of the cut piece should fit perfectly in size.
Lightly pressing the strip, glue it.

It is best to purchase a sealant from a window manufacturer or installer. Buying low-quality models will make the insulation of plastic windows a meaningless exercise.

Additional front of work

Another effective measure is the sealing of existing joints and seams heat-insulating material. It is the only solution for improper installation of double-glazed windows.

Explore materials that can be used

There is diversity in this market segment. You can insulate plastic windows for the winter with the following materials.

Mounting foam. It is most popular due to two advantages: affordable price And high speed installation. However, it quickly collapses as a result of temperature changes and exposure to UV rays.
Mineral wool. It is fire resistant and environmental safety. With its help, they usually insulate the window sill or large gaps between the window and the wall.
Silicone sealant. Pros - low price and reliability. Minus - poor thermal insulation.
Special film. It is transparent and is glued onto the double-glazed window itself, which allows you to save more heat (up to 70% of it sometimes escapes through the glass).
Styrofoam - the most cheap option. With it, you can close the seams in the slopes.
Construction tape. It is usually glued on top of a sealant or mounting foam in order to improve thermal insulation characteristics.
Warm mixes. Used for external sealing of seams and joints.

Film

Glue the glass with the above film. It is sold in rolls, so it is convenient to cut it. We do everything in the following sequence:

We clean windows.
Cut the film to fit the window. It is necessary to leave an allowance of 1-2 cm for each side.
Remove the protective layer.
Wet glass and film.
Glue and level it with a plastic spatula.
Cut off the excess with scissors or a cutter.

outdoor work

Before the onset of cold weather, the outer part of the facade should also be prepared. To do this, close up the external slopes and cracks (if any) with a warm mixture. This can only be done at a positive temperature.

Sealing seams and cracks

If even small gaps are observed, they must be repaired with any of the materials listed above. It is better to plug large joints with cotton first (or similar material), and top with foam.

Conclusion

The problems listed in this article can only occur if the double-glazed window was installed incorrectly. An exception is if you have had them for a long time (more than 10 years). Therefore, if problems arise in new windows, the first thing to do is call the installer - he is obliged to correct his shortcomings.
