What can be cooked from squid: quick and tasty

"What are the best window profiles?" - a question that is asked by everyone who wants to finally install energy-saving windows in their home. However, despite the external similarity of all structures, inside all the profiles are completely different, some of which do not correspond at all to SNiP RF and are not recommended for installation in residential premises. First of all, when choosing a window system, it is necessary to pay attention to the number of cameras and the thermal resistance coefficient (the higher the better). The next important parameter of PVC windows is the provided possibility of reinforcement - this increases the load-bearing characteristic of the structure, contributes to an increase in the service life of the system and its resistance to plastic deformation. To make it easier for the buyer to decide on the choice of a high-quality window system, this rating... So, TOP 10 the best firms and models window profiles PVC:

aluPlast

Aluplast opens the quality rating of window profiles. The company provides a good assortment technical solutions for window systems... The latest developments in energy efficiency are embodied in the AluPlast energeto series. The Energeto 8000 model has excellent thermal resistance values ​​when installing a triple glass unit - 1.27 m2 * C / W. According to the manufacturer, if the structure is not reinforced with steel (this reduces the bearing capacity), its thermal conductivity is significantly reduced, reaching a thermal resistance coefficient of up to 1.67 m2 * C / W.

Deceuninck

Deceuninck is on the 9th place in the rating pvc profiles... The Belgian company has been manufacturing PVC window blanks for about 40 years at production facilities located in Europe, Asia and North America. The flagship of all Deceuninck lines is the 84mm Eforte model. This system it is recommended for installation even in the northern latitudes of Russia due to the high coefficient of thermal resistance - 1.1 m2 * C / W. The service life of "Eforte" is 30-40 years, subject to the temperature range from -60 to +75 degrees Celsius.

Proplex

The Russian company Proplex ranks 8th in the rating of window profiles in 2018. All Proplex products are manufactured in Russia, therefore, prices for finished products from this profile are much lower than imported counterparts. Proplex produces 5 different window systems: 2,3,4,5-chamber. For installation in summer cottages, loggias and non-residential premises a two-chamber Proplex Outline is recommended - the cheapest design with a heat resistance coefficient of only 55 m2 * C / W. A more reliable system recommended for installation in apartments and residential premises is the four-chamber Proplex Comfort with a thermal resistance of 0.8 m2 * С / В, which fully meets the requirements of SNiP RF.

Kaleva

The seventh place in the rating of pvc window profiles is taken by the Kaleva brand. The firm produces a dozen different models, each of which has its own advantages and disadvantages. The most inexpensive option with everything you need is Kaleva Standart - this is a four-chamber profile with the possibility of steel reinforcement and a built-in double-glazed window filled with an inert gas argon, which has a very low thermal conductivity. The five-chamber window system Kaleva Titan Plus is the most heat-saving and sound-suppressing design of the company. Feature of Titan Plus: in addition to the main two-chamber 40mm step-glass unit filled with argon, blinds and one more external glass are built into the system - thus this model provides an incomparable degree of insulation, thanks to a step-glass unit with three independent air partitions, two of which are filled with argon.

Montblanc

Montblanc (read MONBLAN) is the leader in the 2018 ranking of plastic window profiles in terms of price-performance ratio. Mont Blanc is an Austrian company that has been producing low-cost high-quality profiles for translucent structures for over 15 years. Due to the opening of the Mont Blanc industrial plant in the Moscow region in 2001, the company gained wide popularity in Russia. The company produces several lines of window systems: Montblanc, Reachmont, Goodwin and ECP. All products have a guaranteed service life of 40 to 60 years and an installation width of 58 to 70 mm, except for the eighty millimeter Montblanc Grand with six air compartments. A four-chamber system Montblanc Quadro with a thermal resistance coefficient of 0.8 C / W per m2 is recommended for installation - this is a high indicator that meets the requirements of GOST and Building codes and regulations in many regions of the Russian Federation.

Salamander

TOP 5 rating of profiles for plastic windows 2018 opens one of the most expensive brands in the ranking. The company has three different systems in its range: Salamnder 2d / Streamline / BlueEvolution. The cheapest option is considered to be a three-chamber 2D with the possibility of reinforcing the inner chambers with steel. Wall thickness of Salamander 2D: outer 3mm, folded 2.5m, and inner 1mm - this provides a good noise reduction rate (up to 46dB) and high energy efficiency class A +. This model is designed for the installation of a single glass unit. Salamander BlueEvolution is the next model recommended for installation in any region of Russia. BlueEvolution is the only profile available on the Russian market (meaning by reasonable price) with a maximum width of the built-in glass unit - 60mm (if desired, you can install a three-chamber glass unit). Salander BlueEvolution is ideal for the continental climate of Russia: it protects from heavy rains, effectively maintains the temperature even at -40 degrees, and reliably resists drafts thanks to the elastic rubber seal.

KBE

The 4th place in the rating of pvc window profiles belongs to the German manufacturer KBE. The names of the KBE lines are banally simple and depend on the profile width: KBE 58/70/76/88. As anyone who plans to change windows should know, the wider the system, the more chambers in it, which means that the heat saving rates of such a structure are obviously high.

The best option for installation is the KBE76MD model - this is a six-chamber construction made using greenline lead-free technology from recycled polyvinyl chloride. Recycling PVC allows you to "kill" "two birds with one stone" at once: to dispose of PVC waste, and to save on the cost of raw materials, which directly affects the retail price of the product.

The most important thing in the greenline technology from KBE is the complete preservation of the physical and mechanical properties of the material, that is, the raw materials for primary processing are no different from recyclable materials. The best product from KBE is the 88 mm KBE AD made using greenline technology: this model has an outer wall thickness of 3 mm and 6 independent air compartments inside with the possibility of aluminum reinforcement - all this provides an unconditionally high rate of thermal efficiency and noise reduction.

VEKA

The bronze medalist of the rating of the best pvc window profiles goes to VEKA. VEKA offers 8 models of class A with an outer wall thickness of 3mm. The most economical solution is VEKO Euroline: a design with three air chambers designed for a step-glass unit up to 24mm (usually two glasses - one chamber), the sashes and frames in which it is possible to reinforce for greater system reliability.

The energy-efficient A ++ class VEKO Swingline series will be the optimal solution in terms of price and quality for offices and apartments: 5 independent air chambers with an outer wall thickness of 3 mm will provide warmth and comfort in the room, even in harsh winter evenings... The most expensive and massive example is VEKO Alphaline. This model is equipped with six air compartments with a total width of 90mm - these are the most heat-saving windows from VEKO, in which you can install a double-glazed unit up to 50mm thick (3 glasses) and enjoy peace and quiet all year round.

WDS

WDS ranks second among the best profiles for plastic windows in 2018. The manufacturer has several product lines in the assortment, each of which has a difference in noise reduction coefficient, heat saving and the number of cameras: WDS 400/500, WDS 4/7/8 Series. The best in terms of price-quality ratio is the A-class model 60mm WDS4, equipped with 4 independent air chambers, the possibility of aluminum reinforcement up to 1.5mm. For northern latitudes, it recommends the WDS8 series for installation: a six-chamber metal-plastic profile with the ability to mount a two-chamber double-glazed window up to 44 in width - this model retains heat 2.5 times more efficiently than the WDS400 / 4Series.

Rehau

Rehau is the leader in the rating, the best profile for plastic windows in 2018. The range of the company consists of 7 types of profiles with a different number of air chambers, construction widths and sound insulation levels. The Rehau Euro-design series is an affordable and high-quality three-chamber profile with a thickness of 60mm, therefore it is recommended for installation for those who do not want to overpay. For lovers of sound sleep, Rehau Intelio will be a real find: a five-chamber 86mm thick profile with a noise reduction coefficient of 36dB (without a glass unit).

In cold climatic zones, the 86 mm Rehau Geneo will help save up to 80% of heat: the six-chamber design provides high tightness, maintains a colossal gap between the temperature ranges in the room and outside the window, and also creates reliable protection from drafts, thereby maintaining comfort and coziness in the room throughout the winter, even at -60 degrees. According to the manufacturer, all Rehau products have a minimum service life of 40 years, and some models even 60 years.

2. The second most popular are plastic windows of the Century (VEKA). On average, 2510 hits per month for 2019.
3. In third place are KBE windows. Average 755 hits per month for 2019.

Which profile for windows is better according to GOST

GOST is an interstate standard, the requirements of which must be observed in countries: Russian Federation, Armenia, Kazakhstan, Kyrgyz Republic, Moldova, Tajikistan, Uzbekistan.

The criterion for the quality of plastic profiles for windows in Russia is GOST 30673-99 “PVC profiles for window and door blocks. Technical conditions ".

Criteria and profile class according to GOST 30673:

Thus, the best profiles, according to GOST 30673, are:

PVC window profiles of any brand with a thickness of the outer front wall from 2.7 mm with a heat transfer resistance of more than 0.8 m 2 ° C / W

They are required to meet other quality criteria in accordance with GOST.

PVC window profile quality according to European standard

To determine the best profiles in Europe, the European standard EN 12608: 2003 is applied.

European standard EN 12608: 2003 "Polyvinyl chloride (PVC-U) profiles without plasticizer for the manufacture of window frames and doors. Classification, technical requirements and test methods" also has the status of a German DIN standard. The requirements of the standard are applicable for countries: Belgium, Denmark, Germany, Finland, France, Greece, Ireland, Iceland, Italy, Luxembourg, Malta, Netherlands, Norway, Austria, Portugal, Sweden, Switzerland, Slovakia, Spain, Czech Republic, Hungary and the United States. Kingdom of Great Britain.

The European standard EN 12608: 2003 has much in common with the Russian GOST 30673, since the domestic standard is an edited version of the European one.

A distinctive feature of the European standard is the division of the profile class into two different climatic zones "M" (zone of temperate climate) and "S" (zone of hot climate).

Profiles designed for hot climates (S) can also be used in temperate climates (M). In countries where both exist climatic zones, profiles intended for operation in a temperate climate zone (M) must not be operated in a hot climate zone (S).

The classification of the main profiles according to their impact resistance, determined using a falling striker at a temperature of -10 ° C, is also associated with a significant difference in climate. Profiles of 1 and 2 classes are distinguished.

EN 12608: Class of PVC window profiles for the thickness of the outer front walls

• Class A - greater than or equal to 2.8 mm
• Class B - greater than or equal to 2.5 mm
• Class C - not standardized

It can be assumed that the thickness of the outer wall of the PVC profile is 3 mm, perhaps the most important characteristic of a PVC window, although the European standard says that this should not be understood so.

How to determine a quality PVC profile by its appearance

In the finished window, only the appearance of the profile remains the only method for determining its quality. It is a rare necessity to carry out an examination, disassemble and cut a PVC window frame to check its class. It is much easier to find out the quality by inspection.

So how to determine the quality "by eye".

Manufacturer marking

The film has a PVC profile mark applied by the manufacturer. The protective film covers the main surface of the PVC profile at the stages: from manufacturing to installation in the opening. To avoid damage, the film must be removed immediately after installation. Under the influence sun rays the adhesive layer of the protective film will be absorbed into the deep layers of the profile and spoil it. Also, the brand is indicated on the profile itself in the form of laser-engraved numbers and letters.

Uniformity and smoothness of the PVC profile under the film

Homogeneous, even, uniform and smooth surface is a criterion for the quality of the window and profile. The presence of inhomogeneities, deformations or other flaws visible to the eye on straight and flat sections of the profile may indicate poor quality.

Window frame sealant - shape, type, color

The seal is one of the most important profile elements. A poor-quality seal will not protect against moisture and drafts. Pay attention to its elasticity and absence of damage. The presence of the third sealing circuit does not significantly affect the frost protection, but protects the fittings from the aggressive external environment. Color - does not affect quality. White, black, gray and caramel color of the seal will protect the window equally well. Seals made of EPDM rubber have a more elastic feel and are inserted with separate cords (unlike co-extruded TEP seals).

Frame box width
The thicker the window frame, the higher the thermal insulation properties it will have. The number of cavities in the PVC profile - chambers - also affects the characteristics. More cameras, a warmer profile. However, you will not see the profile camera externally. The 70 mm profile can have 3, 4 or 5 chambers.

The chambers in the profile are counted not by the total number of cavities separated by partitions, but by the number of chambers on the way from the outer (street) wall to the inner (room) wall.

Sales volume of plastic windows by PVC profile brand

Among the plastic profiles for windows there are their own "Mercedes" and their "Lada". There is budget options profiles and exclusive, luxury lines of PVC profiles. At the same time, most often, expensive and cheap profiles are sold under one brand.

Profiles of German brands REHAU, VEKA, KBE, Deceuninck are in the greatest demand. However, this does not mean the poor quality of domestic profile systems or other PVC profiles, which are abundant on the market.

Profine is the company that owns the KBE brand, along with TROCAL and Kommerling.

In Germany, plastic windows first appeared in the middle of the 20th century. The popularity of plastic windows in Germany and the growing interest in them in other countries contributed to the opening of production facilities of German companies, including in Russia.

Three most popular PVC profile manufacturers have subsidiaries in the Russian Federation: Rehau, Veka, Profine (owns the brands KBE, Trokal, Kemerling). The dominance of German companies in the production and sale of PVC window profiles is a merit of effective development and its expansion.

Relying on the popularity of the brand, however, you can get into a situation where preference will be given in favor of a lower quality product - since profiles of different classes are produced under the same brand.

1 ... To choose the best PVC profile for a window, compare profiles of the same weight category.

Traditionally, profiles are divided into three main groups:

There are also special profile systems that cannot be directly compared for this gradation. For example, there are three-chamber PVC profiles with an installation depth of 70 mm, or 100 mm (or more) systems with 4 chambers.

2. It is correct to compare PVC profiles by physical and technical parameters in the certificate of conformity.

For use on the territory of the state, PVC profiles must pass a certification system and receive their quality class based on test results. Detailed results appear in the annex to the certificate of conformity for a specific system (PVC profile of a specific model).

3. It is correct to compare not only the PVC profile itself, but also to know the manufacturer: what materials are used in the window in addition to the PVC profile.

The best windows are produced by an experienced manufacturer using quality and proven components.

Often, even the best profile can be spoiled by unreliable thin-walled reinforcement, poor-quality welding, or poorly assembled structure at the factory.

Pay attention to fittings, glass units and other structural elements.

4. Trust the installation to professionals. The quality of installation ultimately determines how long and how well the window will work.

It is better to entrust the installation to an experienced team of installers or a specific specialist.

It is not worth paying for a quality product if unskilled workers will do the installation. The installation scheme itself and the stages of its implementation are also described by regulatory documents. For example, the installation of windows in accordance with GOST and the installation of plastic windows in a wooden house differ in stages and preparation.

Currently, in the Russian market of window products, despite the increasing number of sales of wooden and aluminum structures, the leadership is retained by plastic windows. This is facilitated by the mass of advantages that PVC products... The main ones, of course, are excellent heat and noise insulation, long service life, the ability to use additional accessories that increase the functionality of the window ( mosquito net, thermometer, etc.), as well as great looks coupled with an affordable price.

As you know, the basis of plastic windows is a profile. In the entire light-transmitting structure, it accounts for approximately 10% of the entire area of ​​the product. The remaining 90% is a double-glazed window.

It is no secret that all PVC profiles included in the windows sold are the same. In order to choose the best option that would fully meet the requests in terms of appearance, level of sound and heat insulation, as well as price, the buyer needs to have an idea of ​​each element of the window, be able to freely operate the technical terms associated with each of its components.

In this article, we will take a closer look at the main points that you should pay attention to when choosing a window profile, describe its design, and explain the meanings of the main technical terms.

How many cameras should a plastic window have?

The image is clickable.

When considering the characteristics of the model of the light-transmitting PVC structure of interest, special attention should be paid to three points:

• profile;

The most significant characteristic of a profile is its intimacy, that is, how many cameras it consists of. Their number directly determines how well the plastic profile retains heat.

Profile with three chambers... For residents of regions where cool weather conditions prevail most of the year, the most preferable option is the three-chamber window profile. Three chambers reliably protect the structure from blowing, which means that they perfectly retain heat in the room. In addition, they have a built-in metal frame designed to reinforce the plastic sidewalls. A three-chamber profile of a plastic window, as a rule, has a width of 5.8 cm.

Profile with four or five chambers... Products, which include four, are either intended primarily for use in regions of the country in which the summer season is not long, and the temperature conditions clearly leave much to be desired. The protection provided by the profile with such an increased number of chambers can cope with even the lowest temperatures (30 C and below). Therefore, inside the room, glazed with windows with a multi-chamber profile, it will be warm and cozy in any weather. It should be noted that the use of such windows in warm regions of the country is not very justified due to: mild weather conditions; prices that significantly exceed the cost of their three-chamber "brothers".

Single-chamber and double-chamber profiles. They are mainly used for glazing apartments and private houses located in the southern part of Russia. A design flaw that prevents them from low temperatures to efficiently cope with heat retention is more than compensated for by their price - it is significantly lower than the cost of plastic window models, the profile of which has a larger number of cameras.

Structural elements of the plastic profile. Clicking on the mouse enlarges the image.

As a result... If you need maximum protection from the cold, opt for models of plastic windows with 4 or 5 chambered profiles. If there is no need for maximum heat saving in a glazed room, for example, in the southern regions of the country, where hot weather prevails, one- or two-chamber PVC structures should be chosen.

For most buyers, the best solution for a home would be to purchase three-chamber systems.

Criteria for selecting a profile, depending on its thickness.

Sectional profile. Click to enlarge.

An important characteristic of a PVC profile is its thickness. It depends, first of all, on the number of chambers and, indirectly, speaks of the ability of a window to retain heat: the wider the profile so, as a rule, it is warmer.

When choosing the optimal width of the profile of a plastic window, it must be borne in mind that there are only a small number of options, of which the following should be distinguished:

58 mm... The profile, 5.8 cm wide, is the most demanded in the Russian market for window constructions. Against the background of the rest, more "fat brothers", it stands out for its low price with rather tolerable characteristics. As they say - cheap and cheerful. However, if the buyer pursues the goal of glazing a window opening without pretending to be super-effective, then the models of a plastic window with a 58-mm profile will fully satisfy his desire.

70 mm... The profile width of 7.0 cm allows the product to place from 3 to 5 chambers in it. This thickness is more than enough to provide the glazed room with an adequate level of heat and sound insulation.

90 mm... The widest version of the profile for PVC windows, which best copes with the issue of keeping heat in the apartment. Contains up to 6 cameras. The main disadvantage of such a 9.0 cm solution is its price, which is significantly higher than other similar products with a smaller thickness.

There are also constructions, the profile width of which is quite impressive 110-130 mm! Such windows are also called "Danish" or "Dutch". They are, so to speak, designed for the amateur.

Sectional glass unit.

A double-glazed window, as mentioned above, occupies about 90% of the area of ​​the entire window. Today there are three types of double-glazed windows, differing in the number of glasses installed in them:

• Single glass option... Not suitable for installation in a residential building due to the lack of characteristics of such a double-glazed window. The main flaws in the design of a single glass unit are poor heat retention, as well as lack of protection against. With the onset of the cold season, such disadvantages can contribute to cooling the room, as well as the formation of an impressive layer of ice on the glass.
• Double glass construction... It is the most optimal solution for installation in an apartment, or private house at the expense of good ratio prices and characteristics. The so-called is practically excluded, and the heat in the glazed room is preserved much better than when using a double-glazed unit, which contains only one glass.
• Three-glass solution... With the installed triple glass unit, you can achieve not only the greatest heat savings, but also the maximum protection of the apartment from all kinds of noises entering its territory from the street. Triple glazing has only two drawbacks - high cost and.

From the above information, it follows that for most buyers the most the best option there will be a purchase of double-glazed windows, which will include three glasses. With a shortage Money you can opt for a double-glazed window with the best price / quality ratio.

Selection of a profile depending on the manufacturer and class.

When choosing a suitable window profile, in addition to its characteristics, its brand and class should be taken into account. Regarding the manufacturers of this type of product, it can be noted that today in the domestic window market you can find a fairly large number of brands that produce various models of plastic windows that differ in their constituent elements and, accordingly, characteristics.

Important! This issue was most fully covered in our previous materials entitled "" and "".

Now a few words about choosing a profile class. There are two classes of such products:

Profile class A can be used both in residential buildings and geometrically complex facade structures. Has a long service life, has a wall thickness of at least 3 mm.

Class A profile. Click to enlarge.

As a consequence design features it is customary to refer to the class B profile as a budget decision. The main factor influencing the price is the presence of a thin wall of the product. It is precisely because of the savings in the thickness of the material used for the chamber wall that the manufacturers of PVC profiles class B got the opportunity to keep prices for their products as low as possible. Price at a price, however, the buyer should remember that such a marketing ploy cannot but affect the service life of a plastic window equipped with such a profile - the service life of the system will be significantly shorter.

Summing up some of the above, I would like to draw your attention to a completely obvious fact: all the elements of a plastic window are interconnected. When making a choice in favor of a warm double-glazed window, you should also attend to the purchase of a warm window profile. Otherwise, the design, due to a significant difference in technical characteristics, may turn out to be unbalanced.

The profile for PVC windows is the main element. It affects the functionality, reliability, durability of the structure. Despite the same appearance, the profiles are endowed with different properties, which must be chosen very carefully.

What are the designs?

Currently, there are a large number of companies that produce a variety of. They can differ significantly from each other even from the same manufacturer, not counting competitive products. What is the difference and is it worth paying more?

There are various, comparison of which will help the buyer to make right choice... They are the constructive basis, from which frames and sashes are made. Different materials can be used: wood, metal-plastic, aluminum, polyvinyl chloride. The latter is the most popular: it is equipped with special steel inserts that make the product more durable and rigid. Air pockets help to achieve good heat and sound insulation. Some manufacturers fill these cavities with nitrogen to prevent the windows from fogging up during temperature extremes. PVC profiles for windows must comply with Russian GOST 30673-99 or European EN 12608 SR.

PVC window profiles of all manufacturers are divided into the following categories:

• Class A: characterized by an outer wall size of 2.8 mm. Inside, the thickness does not exceed 2.5 mm. Such a window provides good protection from weather conditions, perfectly keeps the heat inside the room.
• Class B: differs in thinner walls: outer - 2.5 mm, inner - 2 mm. This sample performs worse with thermal insulation, but is suitable for use in warm climates or for glazing balcony rooms. It should be borne in mind that the risk of deformation of the structure increases by 15%.
• Class C: products that do not meet Russian and import standards. Since there is no certification, there are no strict requirements for it, and manufacturers can choose the thickness at their discretion. As a rule, such windows are cheap, but their quality suffers.

On sale you can find an objective PVC profile. It is used for glazing of non-residential technical premises, commercial halls, since it is not able to retain heat with high quality, and there is a high probability of deformation. Outwardly, it is not much different from the standard one. You need to pay attention to the presence of the Object designation: unscrupulous traders sell such products for houses.

How to choose the right profile?

PVC window profiles have different characteristics, the comparison of which will help to make the right choice. You should not rely on the external characteristics of the products offered. Attention should be paid to the following properties:

• Uniformity of the material. Choose products with plastic that is free from flaws. It should be smooth, pleasant to the touch, and uniform. If you notice that the surface is coarse, most likely you are dealing with a counterfeit made in violation of technology.
• The coating should be complete, without streaks, paint traces.

High quality windows are always factory-labeled. You should look for it on the inside of the package. Firms put their own hallmarks with the name, numbers may also be present: they mean the number of the shift that released the batch. The numbers mean the number of the device that produced the window, and the date of release of the goods. Counterfeits either do not have such numbers, or the designations are the same.

• Width. PVC window profile often has a standard parameter equal to 58 mm. Such a window is quite suitable for living rooms and is most often sold in stores. If desired, you can order a thicker version, the width of which will be 70 or 90 mm. The first option is relevant on the upper floors of high-rise buildings, as it can withstand heavy loads and is able to effectively withstand strong winds. It can also be used in cold climates. The second option is considered a premium class, it has a high ability to insulate sound and heat, has high strength, but the weight of such a product is much higher, it is not recommended to install it everywhere.

If you decide to install a 90 mm PVC window profile, do not order a window that is too large. Its flap will be heavy and will begin to sag. It is better to take two small ones or make a structure with two shutters, independent of each other.

• Thickness. It can vary from 2.5 to 3 mm. However, to put such a structure in heavy window blocks not worth it. A heavy load can call into question its reliability.

• The number of air chambers. The profile, the thickness of which is 58 mm, has two chambers, less often it is equipped with three. This is enough for good thermal insulation. More chambers are available for a thicker profile of 70mm. It can have up to 5 cameras. Such profiles are most often used as glazing in high-rise apartments. If necessary, a 90 mm product can be ordered, it can have up to 6 chambers. The level of soundproofing and heat inside the room depends on their number. However, it is worth remembering that the number of glasses and the dimensions of the profile also increase the weight of the structure, and the difference between the 3 and 4-chamber package is not too noticeable.
• The number of double-glazed windows. Different brands of plastic windows offer products with different amounts of these elements. Do not confuse them with air chambers. Double-glazed windows are glasses combined with a frame and a sealant. There are air chambers between them, they can be filled with gas. The lightest is considered to be a single-chamber double-glazed unit, since it includes a pair of glasses. Most often, such products are used for finishing terraces, balconies, loggias, since its mass is minimal, but such a window does not insulate heat well. For an apartment or private house, it is better to use a thicker version with three sheets of glass and two air chambers.

When choosing a double-glazed window, you should also be aware of such a feature of the product: the more glasses, the worse the light will pass through. Four-chamber products are installed in the server regions of the country; there is no need to install them in a warmer climate, this will only be an unnecessary overpayment. If the frost does not exceed -40 degrees, the difference between this product and the three-chamber product will not be noticeable.

When choosing plastic windows, you must first of all pay attention to the quality of the products, and also make a purchase based on the purpose of the profile, the climatic conditions in which you live. It is worth remembering that too cheap stuff cannot be of high quality.

When choosing a profile for a double-glazed window, every detail is important. It would seem that all plastic windows are the same. However, in fact, it turns out that the service life of approximately the same products is different, and the quality characteristics of some often leave much to be desired. Therefore, it is necessary to approach the choice of a profile with all responsibility.

Structure

PVC profile is a plastic frame for a glass unit. Despite the apparent simplicity, this design is not simple. The cross-section of the profile shows many air chambers. Due to them, the preservation of heat is ensured. The more of them, the better the level of thermal protection.

For rigidity and reliability, a metal frame is inserted into the base of the profile. This process in production is called reinforcement. Due to the reinforcement, the profile becomes stronger, the possibility of its deformation and resistance to structural changes under the influence of negative factors is excluded the environment(e.g. rain, gusty winds and frost). The profile material is polyvinyl chloride.

Regardless of the type of profile metal stripes inside it are an important factor that you need to pay attention to when ordering. It is because of them that the profile is called metal-plastic

Longitudinal chambers in frame structures are not only responsible for keeping warm. They are frame reinforcements. The outer sections drain off condensation that can occur inside the cavities due to the temperature difference between the room and the outside.

At the bottom of the structure, they are connected to the atmosphere. Due to this, drops, when they appear, flow down into the street. The presence of such holes does not in any way affect the level of heat in the room: the heat in the room does not decrease. Outwardly, such elements do not spoil the aesthetic appearance of the windows, since in most cases they are closed with plugs or are simply not visible against the background of the entire structure. The presence of these holes indicates a high-quality window. It will be more durable than a modification without them.

Peculiarities

Plastic profile (PVC) is the basis of windows. The reliability and durability of the entire structure depends on him. Sashes and fittings are made from this material, a double-glazed window is installed in it. The main characteristics of the window structure depend on it, including the level of sound insulation, as well as tightness. It also affects the retention of heat in the room.

The metal-plastic profile is a sash and a frame with a different number of chambers (up to 8). The most popular products among buyers are options for 2-3 compartments. The main factor in the technical characteristics is the size of the windows. So, varieties of the panoramic type are characterized by lower noise and heat insulation properties in comparison with their smaller counterparts.

Due to the increase in heat retention in such structures during installation, it is necessary to resort to polyurethane foam when filling the chambers. In addition, structures can have a fiberglass coating with stiffening ribs. One of the important characteristics during installation are the floor thickness and the installation width. It is they who are responsible for the rigidity of the profile structure and the reliability of the doors themselves.

The modern plastic profile for windows differs from analogs in the period of its appearance. Today, its quality characteristics are quite high, as are the decorative possibilities. Technological and functional frames have long pushed their wood counterparts, making the glazing reliable and ergonomic. Unlike wood, PVC does not shrink. Such windows will not deform during operation.

PVC windows can be installed in various types of buildings. They can replace wooden frames in houses that have already completed their active shrinkage phase. At the same time, residents will be protected not only from cold and noise, but also from dust. Typically, such structures stretch any, even boring room design and look harmoniously in the architectural context of buildings of different types. The ability of plastic to imitate any texture makes it possible to use such frames in any design style.

The surface of the profile can be matte, glossy and even three-dimensional. The color solutions of such products are varied today and can satisfy every taste. For example, you can select a profile for expensive types of wood (wenge), show an imitation of aged wood.

When more luxurious solutions are needed, they choose plastic under the stone and even the skin of reptiles. The pattern depends on the preferences of the client: trade marks today are often ready to fulfill an individual order of the buyer.

Specifications

Among the main characteristics of such a profile are:

• resistance to oxidation, high temperature;
• resistance to moisture and water;
• household health safety;
• aesthetic appeal;
• low coefficient of thermal conductivity;
• variability of the forms of structures;
• fitting into any historical design of architecture;
• varying degrees of complexity of structures and mechanisms of operation of windows;
• rich color palette.

In care, such a profile is simpler than a wood analogue. It does not need to be covered with stain or other paint over time. To clean the surface, in most cases, it is sufficient to use a damp cloth or semi-dry sponge. However, in the event of significant mechanical damage, scratches may form on it, which cannot be hidden in any way. This is the main disadvantage of such designs.

Variants with a different number of cameras differ in operational characteristics. For this reason, their choice is often based on the climatic conditions of the region. If winters are cold and windy in it, they try to choose cameras with a large number of compartments. In this case, preference is given to the greater thickness of the glass unit.

The profile itself is environmentally friendly. It is far from the harmful plastic that was produced in production before. Such a frame with sashes will not emit toxic substances during the operation of the window. When choosing, it is important to pay attention to the number of cameras. If the glazing is cold, there should be at least 3. Such profiles can be used for balconies, loggias and rooms technical kind... When it is planned to glaze the heated buildings (school, house, apartment, restaurant), the number of required cameras increases to 5.

Views

In addition to polyvinyl chloride, aluminum or steel is used in the construction of PVC profiles for windows. Metal is used in horizontal and vertical elements ... The production of profiles is subject to the requirements of GOST 30673-99 in our country and EN 12608 SR in European countries.

The profile of the first group is the best option and is intended for residential buildings. It is characterized by a thickness of the outer walls of the order of 2.8 mm and more, of the inner walls - from 2.5 mm. This variety is more resistant to accidental mechanical damage. The analogue of category "B" is distinguished by a smaller wall thickness.

The inner walls have a thickness of 2 mm, while the outer ones are 1/3 mm thinner. It seems to be a little, but that is why such options are less resistant to mechanical stress. They can be used for both heated and unheated premises. Profile marked "C" is characterized by lower thickness values ​​of both walls. In the language of specialists, it is called object.

Unlike the two previous options, it does not have a standardized thickness (it is clearly less than categories "A" and "B"). The disadvantage is the design itself of this type: it does not have opening doors. The solidity of such windows makes them less demanded by buyers. These varieties are used in unheated rooms.

In fact, all existing varieties of plastic profiles for windows can be divided into 3 types:

• economy;
• standard;
• luxury.

Window plastic profile can be main and additional. Today you can buy a profile on store shelves:

• connective;
• stand;
• reinforcing;
• expansive;
• U- and F-shaped.

These are tubular structures with blocks inside, from which the window frame is folded. Cameras come in different shapes and sizes. Some of them are not connected either with each other or with the external environment. They are sealed, while others are used for ventilation. Depending on the size, air filling and the number of chambers, such profiles have different purposes. Some of them are used for technical premises, others can be used for residential buildings.

The L-shaped view is characterized by the reinforcement of the two walls of the profile. The U-shaped type is a three-wall reinforcement. When closed, all parts are hardened. In this case, the choice of profile depends, among other things, on the number of glasses in the structure. Framed cameras directly depend on this.

Varieties differ in the degree of frost resistance. So, options for frost-resistant performance marked "M" are designed for temperatures up to -50 degrees C (control load). Equivalents of normal performance are suitable for regions with subzero temperatures down to -20-40 degrees C. The difference depends on the type of base material used.

Dimensions (edit)

Profile parameters are determined by its width and thickness. In this regard, manufacturers try to adhere to standard values. A common frame version can have dimensions of 58x63x43 mm. The dimensions of the sash are 58x77x57 mm, the impost is 58x87x47 mm.

When the profile contains 6 chambers, its thickness can be 85-90 mm. At 70mm, it usually has up to 5 chambers. In the first case, the profile is thick and is not suitable for every window opening. 70mm is considered the best option if you need up to 5 cameras.

Class A front wall thickness is 3 mm on average. For analogs of category "B" this indicator is reduced by half a millimeter. The non-front side of classes "A" and "B" is thinner by 0.5 mm each from the values ​​of the front wall. In category "C" manufacturers do not indicate data. The mounting width of the profile in some versions can be 104, 110 and 130 mm.

How to choose?

In the modern market for such materials, PVC profiles are presented in a wide range. It is not difficult for the buyer to get confused. However, it is quite possible to make the right choice without being a specialist in the field of construction and installation. To begin with, you should pay attention to the material itself. Appearance plastic can tell a lot about its quality.

When there is no decorative laminated film on the profile (imitation of the desired texture), one attentive glance is enough. High-quality material has a solid structure. There should be no roughness or irregularities in it. Any stains, uneven staining are excluded. Noticeable graininess will indicate a counterfeit product.

You cannot buy such a PVC profile. Typically, such samples can be found in fly-by-night firms. Such companies offer the installation of windows from their own material. It is made from cheap and harmful raw materials. Therefore, one cannot expect any quality characteristics from such a profile.

Yes, and you need to know about the manufacturer before buying components. To do this, you can find out more about the company's reputation based on reviews.

It is important to understand that the profiles have some differences among themselves. They are cut on special machines for certain sizes of structures. This applies not only to the sashes, but also to the uprights and cross members. Therefore, when buying, you need to purchase the entire set from one brand. Otherwise, you can not count on the flawless joining of elements, whether it is a connection by special welding or mechanical hardware.

Cameras

Before buying, it is important to inquire about the number of cameras. Usually high-quality products of famous brands have more than 5. This is enough, while 7 cavities will be a surplus. In this case, we must not forget that not the number of chambers, but the thickness of the walls is more important. After all, it is they who will be responsible for the heat level to a greater extent.

In addition to options with air chambers, today on the market you can find a PVC profile in which the voids are filled not with air, but with a heat insulator. This is mainly a material based on foam (expanded polystyrene) or fiberglass. Such a profile has appeared on the market relatively recently.

However, experts believe that it is more efficient in terms of keeping warm. The disadvantage is the cost of the modification, which is significantly higher than the traditional options.

Width

Since the choice of profile involves a comprehensive analysis, it is worth paying attention to the width of the PVC profile. It is often called assembly depth in the language of specialists. In a standard profile, its indicator usually varies in the range of 50-80 mm. The number of cameras inside the element depends on it. Usually, with a smaller width, the structure has no more than 3 cavities. When the width exceeds 70 mm, their number increases from 4 to 5.

However, it cannot be assumed that the wider the profile, the more cameras it contains. This is far from always true, because depending on the design features, the profile can be wide (for example, up to 9 cm), but with a minimum number of cavities. Such options may differ in excellent thermal insulation characteristics, since the air supply and the dimensions of the cavities themselves are important in this case.

In some cases, the installation depth can be 10 cm. Such options overlap the window opening, therefore, they often do not need to install external slopes. Their distinctive feature is a trapezoidal section shape. These windows are called "Dutch", "Danish". They are certainly better than their usual counterparts, although their installation is far from affordable for everyone.

Seat

It is impossible to buy a plastic profile without knowing the depth of the insulating glass unit. It is this factor that is responsible for the type of glass unit, its quality, as well as heat-shielding properties. A good profile frame is a structure where the glass sheet is at least 1.5 cm from the front cut, overlapping with the profile fold.

If you plan to mount the frame to a depth of 5-7 cm, the seat for glass installation should be 1.8 cm. Few people pay attention to this aspect when buying a profile. However, if you ignore it and rely solely on the width of the profile and the number of cavities in it, you can not be surprised in the future that the glass unit fogs up or freezes.

In addition, there are 4 factors worth paying attention to:

• Linear expansion. It should be minimal so that voids do not form during installation. The higher it is, the smaller the size of the window frame.
• Elasticity coefficient. The presence of steel is a mandatory criterion for choosing a profile. In this case, the thickness of the inner walls (stiffeners) is important.
• Resistance to temperature drop and UV rays. The composition of polyvinyl chloride should contain stabilizers to maintain inertness to loss of color and structure.
• Sealant. From thermoplastic, thermopolymer, silicone and rubber products made of silicone should be preferred. It is resistant to abrasion, inert to temperature changes.

Each profile is supplied with a certificate. It indicates data on the type of product and the place of its production.

Decor

White frames are considered old-fashioned today. It is replaced by profiles with laminated film that can imitate any texture. These can be neutral options (gray, black), as well as wood tones. Of course, such a solution for a window structure will cost more, but by paying 15-20% more, the buyer can equip his home, taking into account the choice of a specific design.

If the choice is made in favor of a colored frame, the shade is selected taking into account the interior and exterior. The frame should look beautiful on the outside and inside. You can build on the color of the existing furniture, doors. A color profile may have a related hue, but different color temperatures are undesirable. However, the choice of a color profile has its own nuances.

Light tones will not heat up in the sun like, say, dark rocky or woody browns. This means that when choosing a colored profile, the presence of metal in the frame is mandatory regardless of the size and shape of the frame. In addition to lamination, manufacturers paint the PVC profile with acrylic spraying, supplement it with metal or wood overlays. A decorative technique is the very shape of the elements, which today is more streamlined and can have a complex relief.

Today you can order a plastic window profile for oak, alder, fir, mahogany, malachite, marble. For more creative design the palette of shades includes yellow, turquoise, blue and wine shades. Thanks to lamination, you can decorate the frames with a film with an aging effect. Optionally, you can choose coatings with a three-dimensional effect, creating a sense of volume and relief.

Manufacturers and reviews

Today, many companies are ready to offer the buyer a PVC profile for windows. The rating of highly rated professional craftsmen includes several companies:

• Rehau;
• Veka;
• Proplex.

Their products are different high quality execution and complies with the established norms of European standards. Such frames do not cause complaints from professional craftsmen, they are easy to install and do not deform during operation. According to customer reviews, these products are characterized by high cost. However, the product is worth it, since the profiles of these brands are durable, resistant to mechanical stress and do not deteriorate over time.

Rehau

German profile manufacturer with a wide range of products. The brand focuses on all strata of society, producing economy class products, standard and luxury. The options are designed for different climatic conditions. The number of chambers in the profile varies from 3 to 6. At the same time, the installation depth ranges from 6 to 8.5 cm. The products are characterized by a high level of noise and heat insulation. Gray seals are suitable for them.

Veka

Russian-made profile produced by German technology... Complies with class "A", intended for use in any regions of Russia with different climatic backgrounds. Today presented 8 different kinds with a different range of installation depths (58-90 mm). The number of air chambers inside the profile is from 3 to 6. Equipped with a strong metal frame, it looks stylish, beautiful and modern.

KBE

This profile has the best quality and technical characteristics in comparison with analogues of other brands. Products are resistant White color that does not fade in the sun and over time. The profile is represented by three options: "Etalon", "Expert", "Expert +".

These are "A" class products with a service life of about 40 years. There can be 3 or 5 chambers in the frame and shutters, 3-4 in the impost. Such products can be installed in rooms with a critical temperature of the region (up to -60).

Depending on the model, the profile can have additional horizontal bridges, which ensures reliable fastening of the rivers and loops.

Proplex

The domestic manufacturer offers customers a profile created using Austrian technology. The Podolsk plant produces varieties with three and five air chambers with a system width of 5.8 and 7 cm. The width of a glass unit, depending on the profile model, can be 4-34 and 12-42 mm. The approximate service life of the product is about 60 years. The profile resistance during heat transfer is 0.78 and 0.81 m2C / W. The designs are distinguished by their whiteness and impact resistance.

The rating lists the best manufacturers whose products have been tested by installers. In addition to the main companies, we can highlight the products of the Mont Blanc, Trocal and Salamander brands. Quite good products can be purchased from Aluplast, Funke, Artek. If there is no brand profile from the rating in the assortment, you can pay attention to these options.

If the choice seems to be a difficult task, you can consult with the seller, having noted the necessary questions in advance. For example, if the buyer lives in the southern region, there is no need to order a six- and seven-chamber profile. In this case, an analogue for 3 cameras will be enough.

For effective protection from the cold, a resident of a high-rise building must not install a product with more than 4 cameras. In your home, a five-chamber structure is enough. However, it is worth starting from the reliability of the foundation, since the weight of the glass unit will be noticeable.

So that the window does not deform over time, before buying it is worth clarifying the presence of a profile to strengthen the frame. In its absence, the window will not close well over time. In addition, its tightness will suffer. In addition, you need to understand that there is no such thing as a cheap profile. In an attempt to save money, you can lose on quality. And this will be reflected in a reduction in the service life of the window.

When buying a profile, you need to pay attention to how exactly the frame is sealed. To avoid the accumulation of condensation, there should be 2 seals at the bottom of the frame of the seals. If at least 1 of them is missing, mold will appear on the profile over time. In this case, the material of the seal itself is also important, which is reflected in its quality characteristics.

For installation, they often buy varieties with a width of 58 mm. This option is relevant for apartments in high-rise buildings and is present in every line of brands. Larger widths are considered premium items. They are more durable, reliable and differ in noise and thermal insulation capabilities compared to the first analogues. However, it is far from always possible to install such structures in high-rise buildings from the point of view of their load on the load-bearing floors.

Finally, it is worth noting at least important nuance: The manufacturer and installer may be different companies. So that in the future they do not throw off the responsibility for a poor-quality window on each other, it is important to initially select the material correctly. You need to go through each paragraph of the article and note what is appropriate in a particular case. In addition, you will have to study the installer rating in order for the profile to be installed as expected.

In order not to run into a fake of a promoted brand, you should go to the manufacturer's website and ask about the address of a particular store. Information about official suppliers will allow you to understand whether a brand profile is actually being sold in a store in your city. If the site administration gives an affirmative answer, you can buy products. When buying a color version of a profile, it is important to look at each element for different shades: the window should look monolithic.
