The reinforcing element of the window is a U-shaped or square profile, which is inserted into the largest chamber located in the center. The thickness of the sheet metal from which the profile is formed is in the range of 1.5 - 2 mm. It is made of galvanized steel and is highly resistant to corrosion. An amplifier is installed in almost all structures, although according to the standards, with a frame length of less than 0.8 m, it can not be used.
Profile PVC profile is a frame, that is, the basis of a window structure, and therefore it must: have a high ability to retain heat: the minimum number of chambers acceptable for the climate of Ukraine is three (for example, "Bluevolution"). This option is ideal for glazing of balconies, private houses, including in the northern regions of the country, as well as residential and office premises in the southern part of Ukraine; differ in structural rigidity: a reinforced profile has excellent indicators of this criterion (metal frame thickness - at least 1.5 mm); comply with environmental standards: for high-quality PVC profiles, safe raw materials are used that guarantee stable technical characteristics, do not emit toxins when the temperature changes, have a stylish design: a profile with a uniform surface is a good base for an ideal window, and the trend is white PVC Salamander, not loses its glossy appearance even after decades.
To be convinced of the quality and high consumer properties of plastic windows, you just need to read about their characteristics in the article brought to your attention and compare them with wooden structures. The text is far from advertising in nature - only objective information. The choice of priorities is up to the reader. Here you will learn how to choose plastic windows, and why some designs are better than others.
Therefore, it will not be difficult to choose metal-plastic windows with the right color, but this must be approached wisely - they must fit into the overall architectural appearance, and not be "black sheep". followingThe last step is the most important, because the functionality of the window depends on your choice, i. its purpose as a whole. How to choose a double-glazed window for plastic windows Which double-glazed window to choose Remember - a double-glazed window occupies more than 80% of the total area of \u200b\u200bthe structure, and its enclosing functionality directly depends on which double-glazed window to choose for the window block. Therefore: Determine what functions your future window should perform (energy saving, noise protection, sun protection, impact resistance, etc.); Please note that a double-glazed window can perform several functions, that is, be multifunctional, and have in its set all the qualities that you need. It depends on the type of glass selected and its location in the double-glazed unit; As already mentioned, the general purpose of a plastic window depends mainly on the type of double-glazed windows installed, so pay due attention to this. We already have part of the answer to the question “how to choose plastic windows”. After determining the configuration and type of double-glazed window, it's time to start selecting the profile system and fittings for the sashes. Which profile to choose for windows Window profile, PVC profile And so, we have a new task - “how to choose the right profile for a metal-plastic window”, and here we will indicate a number of key points: Whether it will be a Ukrainian product or its imported counterpart - today there is not much difference no. Ukrainian-made window profile (for example, WDS, OpenTeck, AlmPlast) is practically in no way inferior to imported counterparts, at a significantly lower price. And it is worth mentioning that some foreign specialized brands have been producing their products on the territory of Ukraine for a long time (for example, KBE in Zaporozhye, Veka and Aluplast in Brovary); The number of chambers and the installation depth of the profile system directly affect the heat transfer resistance coefficient. This means that the “thicker” the profile and the more air chambers in it, the better its thermal parameters; By choosing a wide profile, you get not only a warmer, but also a more aesthetic design. True, here it is necessary without fanaticism - if you choose plastic windows with a 6-chamber system for "cold glazing" of a balcony, then this is not economically feasible; Be sure to pay attention to the thickness of the reinforcement. The strength characteristics of the PVC structure, its operation and safety depend on this, if it is planned to install anti-burglary fittings. The minimum thickness of the amplifier according to DSTU is 1.5 mm; The choice of fittings for plastic windows Window fittings Choose fittings for metal-plastic windows from well-known, well-established manufacturers; For the first floors, complete the sashes with anti-burglary elements; Choose additional equipment for your window: microlift (to limit sagging of the sash); lock-fuse (blocks the mechanism for turning the handle when the window is folded back for ventilation to prevent the scissors from falling out); micro-ventilation (to conveniently ventilate the room in the cold season); handles with additional blocking of opening (especially important for those who have small children); When choosing between a turn-and-turn opening option, stop at the latter (turn-tilt). Experience shows that such a mechanism is more convenient and practical; And finally, we want to point out typical mistakes when choosing new windows, as well as some other important points. Mistakes when choosing PVC windows Mistakes when choosing plastic windows Do not chase discounts. “Buying discounts” rather than PVC windows themselves is the most common mistake when choosing windows. Look only at the final cost of the entire order and already with all the discounts; Metal-plastic structures are individual products (like a suit that is sewn to order). Therefore, under equal other conditions (the same profile system, double-glazed windows, fittings), the price from different suppliers will be different; As already mentioned - do not look for windows REHAU, Kommerling, ALUPLAST and so on. Buy finished products from these profiles and services for their installation, dismantling of old windows, etc .; Demand the execution of the Agreement with a wet seal, and not just a clerical stamp. Pay attention to the warranty obligations specified in the Agreement and the availability of the warranty card. And also - check the registration data (documents); Choose a supplier that has been on the market for a long time and has a good reputation; We hope that the article will help you make the right choice of windows and let them serve you faithfully for many years!
Wooden frames need periodic updating of the paintwork, maintenance of PVC windows is not required. And plastic windows are easier to clean than wooden ones.
Important! The reliability of the entire structure depends on the type of profile. They are made of PVC and at first glance look the same. Thermal insulation is provided by internal air chambers, and metal reinforcement guarantees strength. The higher the profile class, the greater the thickness of the outer wall.
PVC windows have recently appeared on the market, the cavities of which are not filled with air, but are filled with foamed heat insulators - expanded polystyrene, for example, or filled with fiberglass materials. Even with a relatively small number of chambers, their thermal insulation characteristics are much higher than air ones. But for now, their price is also higher.
The role of air chambers in PVC windows Closed longitudinal air chambers in window frames play a dual role. This is an effective thermal insulation and reinforcement of the structure. External chambers, in addition, serve to remove condensate that forms inside the cavity due to the temperature difference in the room and outside. They are connected to the atmosphere at the bottom and drops of water simply flow down to the street. The presence of such holes has practically no effect on the overall level of thermal insulation.
Reinforcing insert Reinforced windows are stronger and more durable. Reinforcement is an essential component of a high-quality translucent structure. It is necessary so that the windows can resist wind loads, and also do not deform due to thermal expansion. This is especially true for regions with significant temperature fluctuations throughout the year.
It is certification that is a tool to protect the buyer from an unscrupulous manufacturer, and also acts as a guarantor of safety, confirmation of the declared quality indicators of the goods.
