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!
The mounting thickness of the exprof Aero breathable window frame is 101 mm. This is the optimal size to ensure a high level of noise and heat insulation even for three-chamber profiles, as well as high-quality ventilation with closed doors.
The ends of the double-glazed window are sealed, the air inside is dry and the glass does not fog up at any temperature inside and outside. In modern double-glazed windows, instead of air, an inert gas is sometimes pumped, most often argon. Its thermal conductivity is somewhat lower than air, but the cost is higher. Whether such a step is justified in terms of energy saving is still a matter of debate. But in relation to the price - manufacturers win unambiguously.
You should make sure that the seller has a certificate for PVC windows, you can additionally request certificates for the profile and other components of the window unit.
It is because of the poor quality of fittings that buyers of PVC windows face the following problems: jamming of the sash; opening the window only with effort; blowing due to the inability to tightly close the sash; creak.
How to choose metal-plastic (PVC) windows, so as not to doubt their quality? Which, according to experts, plastic windows are better to put in a country cottage, and which ones - in an apartment in a city skyscraper?
PVC used for the production of profiles has a number of features that manufacturers are constantly struggling with: 1. Sufficiently high linear expansion, reaching several millimeters per meter of length. In order to compensate for this phenomenon, it is necessary to leave special gaps, use reinforcement and correctly calculate the number of fasteners. The same feature of the PVC profile limits mamaximum dimensions of window structures. 2. Low coefficient of elasticity, but even at the factories it is leveled by the use of metal inserts and the correct calculation of the thickness of the inner walls, which are stiffeners. 3. Insufficient temperature stability and UV resistance. Manufacturers also learned to deal with this drawback by introducing special modifiers and stabilizers into PVC, which preserve the color and structure of the material. In high-quality windows, such additives serve no less than the entire structure. They are, in most cases, completely harmless to humans. But if the frame emits a pungent smell that does not disappear for a long time, do not buy this window. It used lead or cadmium, or even more dangerous chemicals, instead of harmless zinc and calcium.
The system width of exprof profiles is 58, 60 or 70 mm, depending on the type of window and the number of chambers. The manufacturer's profile systems allow installing a double-glazed window up to 36 mm thick in a 58 mm profile, and up to 44 mm thick in a 70 mm one.
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 C. The so-called object (object). As a rule, the wall thickness is not standardized, but less than that of profiles A and B. Such structures are installed in unheated rooms. As a rule, the sashes do not open, the design of the windows is monolithic.
