In this article I will try to tell everything about plastic windows.
It is quite difficult to choose a high-quality plastic window, and even according to a reasonable wall. The cost of a window is determined mainly by the type of profile and double-glazed window; branded fittings can also greatly change the price.
It is very difficult to figure out what profile you need, how many chambers a double-glazed window should have, etc. Asking this to manufacturing companies is almost useless. Almost all companies will charge you the maximum, i.e. you will be satisfied with the work, but it could be cheaper, because... you were given a more expensive profile and glass unit. And it happens that the windows cost you cheap, but in winter condensation appears on them, they freeze - this is not a high-quality window assembly that needs to be replaced and cannot be repaired. Although there are companies that value their reputation and can make you a high-quality window using the material required for your conditions, which is why the cost of the window will be relatively cheap. Of course, the most optimal choice windows, this is the one that your friends have installed, which has been standing for more than a year and has no complaints from the owners. You can safely order such a window and MAINLY from the company that made the window for your friends.
If this is not possible, we will try to figure out what they will offer you when ordering windows from the company.
1 - profile from which the plastic window will be made.
When choosing cheap profiles such as - VEKA, PROPLEX it is necessary to take into account that they sag, make a balcony module out of them (door and window to the balcony) or a window with an opening sash more sizes 1.3 x 1.4 m is not advisable.
When choosing cheap profiles such as - KBE, THYSSEN, REHAU These are more rigid profiles from which, in principle, plastic windows and doors need to be made.
2 - a double-glazed window that can be single- or double-chamber. The chamber is the space between the glasses, filled with rarefied air and gas, which protect your home from noise and cold. If only two glasses are used in a double-glazed window, then it is a single-chamber double-glazed window. Accordingly, a double-glazed window consists of three glasses. Single-chamber double-glazed windows are suitable for windows facing glass balcony, as well as for very well-heated rooms, otherwise you need to install a double-glazed window that provides maximum protection from noise and cold.
To understand what combination of profile and double-glazed window you need, you need to decide on the conditions and objectives of the future plastic window.
If you need minimal insulation from noise and cold, which usually occurs at the exit of a glazed and insulated balcony, then a 3-chamber profile and a 1-chamber double-glazed window will suit you.
If your house is well heated, but street noise bothers you, then you will need a 3-chamber profile and a 2-chamber double-glazed window.
Complete and thorough protection from cold and noise when using a 5-chamber profile and a 2-chamber double-glazed window.
Let's try to figure out why plastic windows at home sweat in winter and what to do to prevent windows from sweating in the apartment. Today, this problem occurs frequently. When they say that windows sweat or fog up, they mean that moisture collects on them. There may be several reasons for this, we will look at them in this article.
If a plastic window smells cold, this could be due to the quality of the window, when the sashes do not fit tightly when closed. This is a manufacturing defect that cannot be corrected - you need to call the manufacturer (if the window is under warranty) to have them change it.

It happens that the window good quality, but the installation is not high quality. Very often, the “jambs” of plastic window installers consist in saving polyurethane foam and not proper insulation slopes, because of which the cold air from the street penetrates into the room without any problems. Here you also need to call the manufacturer to correct the installation of the window.
If not visible reasons window fogging, then we remember “school physics”, when the difference in temperature outside the windows and in the house is very large, then condensation forms on the window. Because the colder the glass in the window, the greater the likelihood that steam in the air will settle on its surface in the form of water droplets. In this case, it is necessary to ensure ventilation of the room and good hood, if we are talking about plastic windows in the kitchen.
Perhaps your basic economy played a cruel joke on you. Many have heard about multi-chamber double-glazed windows and various profiles for making plastic windows, but did not think about it, or thought poorly about how to choose plastic windows.
What should I do to prevent the windows from sweating in my apartment?
These tips are suitable if plastic windows sweat due to high quality workmanship or installation.
A simple, but not beautiful option is to ventilate the room more often.
Look where your battery is, ideally it should be under the window, not on the side. The temperature from the radiator should be higher than the air temperature in the room. If this is prevented by a window sill that cannot be replaced, then you need to drill several holes 5 - 6 cm in diameter in the window sill and decorate them with decorative rings, which can be bought at a furniture fittings store. Ideally, the window sill should not block the battery.
If you have them on your windowsill houseplants- try to remove them. They can block the flow of warm air from the radiator to the window.
In conclusion.
Windows themselves cannot release moisture, which means it comes from somewhere in the room. The air near the window is the coldest and if its temperature is below the dew point, then fogging of the window is inevitable.
Plastic windows (PVC) Rehau are made from polyvinyl chloride. The advantage of such windows is their resistance to physical and chemical influences. The special properties of this material provide designers with almost unlimited possibilities: a variety of colors, shapes and sizes. You will be able to admire not only the view from the window, but also the view of the window itself.
Plastic windows made from the Rehau profile provide reliable sound insulation.
These windows are very durable. Therefore, they are often called metal-plastic.
Also, such windows are highly reliable and they are equipped with an anti-burglary system, ensuring your safety from intruders.
And the main advantage of a window made from the Rehau profile is its high thermal insulation, which will not allow you to freeze in severe frosts.
The price is derived from the following factors, such as the price of window components, the manufacturing process itself, the cost of raw materials, delivery and installation. The production of such windows is a rather complex and labor-intensive process.
The prices for Rehau windows are not exactly cheap, but the money spent on their purchase will be more than repaid to you by their many advantages.

A window is a special type of enclosing structure that allows light to pass through but retains heat worse than walls or a thermally insulated roof. It is impossible to refuse windows, since natural light is mandatory for humans life condition. It remains to improve window technologies and keep up with the times.
Plastic windows- this is the name of our most popular window structures made of PVC (polyvinyl chloride), reinforced with a metal profile. PVC is an inexpensive and durable material that can provide good appearance high performance window frame. The window system consists of plastic profiles responsible for the rigidity of the structure. The main window profiles include elements such as frame, sash, mullion (impost), metal profiles rigidity and plastic glazing beads. They are accompanied by additional profiles: expanders, connecting elements, platbands and other elements.
There are several PVC window systems, differing primarily in profile thickness. There may even be differences in model range one manufacturer. Typical sizes - 58, 70, 82, 90, 104 mm; at the same time, there are other size ranges. Profiles may differ in the number of internal chambers - fenced off spaces. The more of these cameras, the higher thermal insulation properties profile. In addition, the latter can have a different number of sealing circuits - from one to three.
Number of cameras and profile thickness determine its heat transfer resistance coefficient R. According to current standards for the city of Moscow this coefficient should not be lower than 0.8 m².S/W. To achieve this indicator, you will need a PVC profile with a thickness of 70 mm with at least 4 chambers. If you use, for example, a 90 mm profile, the heat transfer resistance coefficient will increase to 1.3-1.4 m².S/W. However, the overall heat transfer resistance of a window is determined not only by the profile parameters, but also by the thermal conductivity of the glass unit.
PVC window finishing. The base color of PVC profiles is white. It is also the cheapest. Colored profiles will cost more. The most in a simple way Decorating PVC profiles involves gluing (laminating) them with acrylic film. Such films are produced in the most various colors and can imitate wood and other textures. Plastic window profiles can also be painted superficially or in bulk. 
By the way, profiles painted in mass without a protective surface finish fade quite quickly. They should be laminated with film or painted on the front sides, and the hidden part, which is visible only when the window is opened, being painted in the mass, does not stand out in contrast.
The reason for fogging of plastic windows? In winter, you can often see condensation on the glass of plastic windows. Where does it come from and how to prevent its formation? - not everyone knows. The actual reason for fogging is simple - moisture contained in the air condenses on cold glasses. However, in some rooms there is condensation on the windows, but in others there is not. Why? The thing is that sealed windows block the flow of air, which in houses with natural ventilation provided through loose joinery. As a result, when the windows are closed, a situation is created where steam is not removed from the room and settles on the cold glass. But if there is a heating radiator under the window sill, then warm air will create a warm convection flow over the glass and dry it. If there is no radiator, then, unfortunately, condensation will form from time to time and cause a lot of trouble.
Slot ventilation helps to partially reduce the intensity of condensation on glass, but then heat loss increases significantly. Most moisture falls on glass kitchen windows. It is recommended to open the window sash slightly when cooking is in progress. This will allow the steam to escape through vent and will additionally ensure air movement in the window opening.
Most of the condensation forms at night, since at this time the temperature of the inner glass of the window is at its lowest. During the day solar heat enough to dry the moisture that has fallen on the glass. Obviously, the amount of condensation formed depends on the temperature of the inner glass, so it makes sense to increase the temperature window design. First of all, we are talking about an energy-saving double-glazed window, the inner glass of which will have more high temperature than usual. 
Mold around windows is a direct consequence of condensation. Water flows from glass and profiles onto the windowsill, creating a humid environment there that is favorable for the development of mold fungi. Condensation can also form on frozen slopes. Ventilation of the window niche in such cases is usually insufficient. It often happens that there is a powerful radiator under the window, but mold still forms. The problem here, most likely, is the wide window sill, which does not allow sufficient blowing of the glass with a warm convection flow. A solution to the problem can be moving the window closer to the room, or making ventilation slots in the window sill, as well as insulating the slopes.
Ventilation problem. Due to the tightness of modern PVC windows, the air flow into the premises is disrupted and, accordingly, air exchange stops. Natural exhaust ventilation stops working, causing a lot of trouble. The most technologically advanced solution to this problem is built-in ventilators - ventilation valves that ensure the flow of outside air into the room when closed window. Such valves may have manual control, hydro-adjustable (using a special sponge element, which opens the valve when it swells) and electronic. In addition, there are valves with increased sound insulation.
If ventilation valves is not provided, then it remains to use slot ventilation, when the sash is opened a few millimeters, allowing outside air to penetrate inside. However, such a measure violates the sound insulation of the window and increases heat loss in the room. But it’s still better than stale air and puddles of condensation on the windowsill.
Drainage holes, present in the design of any plastic window, are designed to remove moisture from precipitation penetrating through the sash seal. The auxiliary function of the drainage holes is to ventilate the cavities of the frame and sash. In some systems such holes are visible, in others they are hidden. At scheduled maintenance plastic windows, the patency of the drainage holes should also be checked.
Depressurization of a plastic window- the situation is quite common. In most cases, windows “siphon” from the first day of installation, which indicates gross installation violations. There are two main reasons: holes in the foam layer around the perimeter of the window and loose fit of the sashes. In the first case, the problem is solved by repeated foaming, but in order for the sash to fit smoothly, the window may need to be reinstalled. During installation, it is extremely important to install the frame in a single plane without distortion. Careless installers often make mistakes when attaching an anchor: the hammer drill moves to the side, and the hole is made in the wrong place. As a result window frame has deviations, and the sash does not fit tightly to it. If the deviations are within 2-3 mm, then you can tighten the sash using the adjustment of the eccentrics of the locking fittings. There is usually a mark on the eccentric that indicates its position. At maximum tightening, the mark is directed towards the room. By turning all the eccentrics with the mark towards the room, we thereby move the window to winter mode. In summer, it is advisable to install the eccentrics with the mark facing outward so that the seals are not squeezed out so much and more fresh air gets into the room.
The plastic window is sealed around the perimeter polyurethane foam. After the foam has expanded as much as possible (this takes up to 12 hours), its excess must be cut off sharp knife, and plaster the seam itself or finish it with a special sealant. The foam in the seams should not be left open, as it is quickly destroyed by ultraviolet radiation.
Remember! Most problems with plastic windows are the result of improper installation technology. As practice shows, not all companies involved in window installation train their specialists at the proper level. Some of them are not only unable to fulfill high-quality installation, but also cannot correct their own mistakes. Therefore, contact only professionals from large companies or on the recommendation of reputable friends. Low price Windows with installation is most often a sure way to disappointment!
Seal. Plastic window systems use various seals, which play an important role in sealing and sound insulation. According to GOST 23166-99 “Window blocks” in heated rooms near the window, at least 2 sealing circuits must be provided on opening sashes and 1 circuit on solid structures. In our climate optimal material for window seals is EPTK (ethylene-propylene-thermopolymer-rubber).
With prolonged use, any seal becomes unusable if it is not periodically treated with special products containing silicone oil. These and other products are included in the plastic window care kit, which should be purchased immediately from the installer. Sometimes sealant milk is included as a bonus. Replacing seals is possible, but it is better to teach it a lesson to a specialist.
When installing window sills, they are usually loaded with weights while the foam dries. Cans of water are often used as cargo. There is nothing special about this, except for one small trifle: according to the well-known law of physics, a spherical glass mold(V in this case jar) filled with water turns into a magnifying glass that can easily focus Sun rays onto the surface of the plastic and burn into it big hole. If you are not happy with this outcome, simply cover the jars from the sun with cloth or paper.
In some panel houses heating radiators are hidden in the wall. If you have to install a plastic window in an apartment of just such a house, be extremely careful when dismantling the old block and especially the window sill! The fact is that the window sills from below are fixed with metal corners, which are aimed at the concrete wall on dowels. Do not try to pull these dowels out of the slab: they may become driven into the heating pipe. It’s better to cut the corners with a grinder or just bend them under the windowsill if a huge flood is not in your plans.
If you transport a PVC window yourself, know that it is not advisable to turn it upside down. The fact is that some manufacturers of PVC windows do not install spacers at the top of the double-glazed windows, violating the assembly technology. In the inverted position of the window, the glass unit can move and rest at an angle against the metal part of the impost fastening, which is why chips form on the glass at the point of contact, which can cause cracks in the glass - if not immediately, then later: for example, in severe frost.
In winter, in severe frosts, normal soft toy, fur hat, pillow, etc. may cause damage to the glass unit of the window. Such a nuisance can occur if any of these harmless objects are placed on the windowsill and leaned against the glass. A section of glass, closed from the influx of warm air, will after some time cool to a temperature much lower than the temperature of the adjacent surface, and the glass will burst. By the way, you can also accidentally damage the windshield of a car!
To care for PVC windows, it is recommended to purchase first aid kits with special means, of which oil is most often used to lubricate fittings and Silicone Grease for rubber seals. They end the fastest. In order not to spend extra money on buying a first aid kit, use alternative means: for accessories - oil for sewing machines(any housewife can find it), and for rubber bands - liquid (not spray) silicone lubricant for rubber car seals. The effect is the same and will last longer.
November 30, 2018PVC profiles have gradually been replaced wooden windows who moved from the lower to the higher segment. Now the cost of a set made of wood is at least 20% more than that of polyvinyl chloride. Disputes between supporters different materials continue to this day. Many people love wood for its appearance, environmental friendliness and durability. Oak windows, the most expensive option, will last up to 90 years versus 30-40 years for plastic. From an aesthetic point of view, wood is also superior to plastic. Nat...
A great discovery occurred in the 60s of the last century: German technologists created the world's first plastic windows. To this day, the same materials are used as 50 years ago. The basis of the entire process is a compound called PVC for short, that is, polyvinyl chloride. In our country, these foreign inventions appeared relatively recently, in the late 90s. And they met great resistance. Only in the last decade have plastic profiles begun to spread...
Myths associated with the dangers of PVC profiles are gradually disappearing. Even former opponents are installing plastic windows, and it is difficult to find an apartment where the old wooden frames still remain. However, the safety of plastic is still questionable in some cases. Do the windows highlight harmful substances? Can they withstand extreme heat or cold? And how reliable is the protection against thieves? These are questions that customers regularly ask before installation. Where did they come from...
Currently wooden buildings are popular. However, plastic windows are most often used for glazing such buildings, most likely due to their prevalence, as opposed to the more logical use of wood here. If you decide to install plastic windows in wooden house, You should take into account a number of characteristics so that the installation process in this case goes as smoothly as possible. Please note that all wooden...
Double-glazed windows are filled with inert gases to reduce heat loss. According to experts, a double-glazed window filled with such gas retains heat in the room by 40% more. Krypton is much more expensive than argon because it has a thermal conductivity 1.5 times less than argon and 2.5 times less than air. Therefore, the heat transfer resistance of such a double-glazed window is quite high. Many people are concerned about the question of whether the gases inside such glass will cause harm...
PVC (polyvinyl chloride) in its pure form is too fragile for the production of plastic windows, and therefore it is not used for these purposes. In order to make it a full-fledged material for the manufacture of window structures, you need to add PVC composition special substances. For example, lead salts are present in the composition to give the material strength and rigidity. Recently, lead salt has been replaced by calcium or zinc salt. They give PVC material strength, moisture resistant...
Plastic windows are the best invention for the Russian winter
It should be noted that winters in Russia are severe. Every time it comes, we think about how to make the room warmer. Glazing it with plastic windows plays a big role in maintaining heat in the room, as well as saving money on heating. To make the room warmer, Special attention You should pay attention to choosing a double-glazed window that has additional heat-saving properties. Today the most common are o...
Plastic windows have long ceased to be a novelty, but, unfortunately, there are still cases when a lot of money spent on their installation is literally thrown away: due to an incorrectly selected design, low-quality materials or unprofessional installation of such windows very quickly become unusable and best case scenario require expensive repairs, and in the worst case, complete replacement. We have prepared information about the most important parameters that you must pay attention to when ordering and installing windows, and asked for advice from a professional expert from the Archdialogue agency.
Well-installed, high-quality plastic windows should serve faithfully for many years, reliably protecting your home from bad weather and street noise. They have whole line advantages over outdated ones wooden frames: do not rot or rust, do not dry out from the sun and do not swell from moisture, do not require regular puttying and painting, have convenient opening mechanisms, are reliable, comfortable and durable in use. The only disadvantage of plastic windows is their flammability and very heavy weight. To select windows that meet the most best characteristics, you need to pay attention to several parameters, which we will discuss in detail.
Design
Plastic or PVC windows consist of a hollow multi-chamber plastic profile with metal reinforcement, double glazed windows and fittings.
A PVC profile usually has from 2 to 8 hollow chambers. It is believed that the thicker the profile and the more chambers there are, the warmer the windows. However, you should not overpay a lot of money for an extra number of cameras: plastic already has very low heat transfer, so to save money in our climate it is enough to install quality windows with a three-chamber profile, a two-chamber double-glazed window and two sealing contours - this will ensure effective heat retention inside the room during the cold season.
Double-glazed windows
Heat retention in the house is largely ensured by properly selected double-glazed windows. In residential premises, it is safer and more expedient to install windows with double-glazed windows (i.e., with 3 panes of glass and 2 air chambers between them). Compared to single-chamber double-glazed windows, this is a more expensive option, but the price difference will be justified significant savings on heating and greater comfort in winter period.
Single-chamber double-glazed windows (with 2 glasses and 1 air chamber) are significantly inferior to double-chamber ones in heat conservation, but their undoubted advantage is more a light weight And affordable price. Windows with single-chamber double-glazed windows are recommended to be installed in regions with very warm climate or in non-residential premises: on summer cottages, balconies, loggias, verandas, etc. Some manufacturers claim that their single-chamber double-glazed windows, filled with inert gas or, conversely, with highly rarefied air (“vacuum”) inside, retain heat as effectively as double-chamber double-glazed windows, and are much cheaper. However, you shouldn’t believe these marketing tricks - it’s better to pay extra once and order a high-quality double-glazed window than to suffer and suffer from the cold for many years.
Three-chamber double-glazed windows (with 4 glasses and 3 air chambers) are very heavy and require especially durable fittings and special technology installations. In addition, the four glasses included in their composition transmit light much worse compared to single-chamber and double-chamber double-glazed windows. It is recommended to use them only in the extremely cold climate of the Far North, preferably on blind, non-opening windows.
Previously, it was believed that the wider the air chamber of a double-glazed window, the less heat would escape to the street through the window. But now it has already been proven that she is fat air gap does not always guarantee effective heat conservation: according to the law of convection, warm air from the internal warm glass will rise up, and the cold air from the external cold will fall down, replacing it. Thus, there is a constant circulation of air masses inside the glass unit, which leads to significant heat loss. Therefore, modern manufacturers are trying to reduce the distance between the glasses.
Reinforcement
To provide additional strength to a heavy window structure, the PVC profile is reinforced with an insert, the metal thickness of which, according to German standards, must be at least 1.5 mm for regular windows and 2 mm for large windows. It is advisable to choose a PVC profile with closed rather than U-shaped reinforcement - it is much stronger and more durable.
Accessories
When ordering plastic windows, it is very important to choose high-quality, strong fittings, especially for structures with double-glazed windows: weak fittings simply cannot withstand the weight of a heavy frame with three glasses, and within a few months after installation, serious problems with the windows may begin, such as drafts, frame skew , difficulties with opening and closing.
Additional functions
When ordering plastic windows, you can choose the most suitable option for each home. For example, if your windows overlook a noisy road, it is very useful to take care of additional sound insulation. It is achieved by installing double-glazed windows with different glass thicknesses and different widths air chambers between the glasses, which will dampen the resonance. Top winter ventilation function, profile with built-in ventilation, mosquito net and the opening regulator (“comb”) will be very useful additions to new windows.
What to look for when choosing
To avoid many problems, it is better to order windows from reliable, good reputation companies. After all, in addition to High Quality the windows themselves, you need confidence that they will be installed correctly: the vast majority of problems with plastic windows occur not so much because of their poor quality, but because of unprofessional installation. Serious companies have a quality certificate for their products and provide a guarantee on their windows for at least 5 years. Another everyday recommendation is to hire someone you know as an assistant who has experience in ordering windows, so that if necessary, he can advise you on something or clarify some important details.
Window adjustment
During operation, any, even the highest quality, windows sag over time due to heavy weight and permanent loads, their mechanisms begin to work poorly, the frames shift and no longer fit tightly to the base. Therefore, all windows require periodic adjustment. If it is blowing from the window, its handle does not turn well, or there are difficulties opening and closing, this is an indicator that it is time to make an adjustment. You can adjust the window either yourself or by inviting a professional technician to your home.
