Wooden frames, as an alternative, also cannot be called an example of environmental friendliness. In their production, glues, impregnations, varnishes and paints are used, often with a dubious composition.
Installation depth In addition to their own heat-shielding properties, such frames allow you to install more durable fittings, thick double-glazed windows and additional contours of insulation and sound insulation. But the width of the profile does not necessarily indicate the number of chambers - there are profiles with fewer cavities, but with a width of 8 or even 9 cm. In terms of general thermal insulation properties, they are better than narrow multi-chamber ones - it is not the number of chambers that matters here, but their size and stock air in them. We can conclude that the greater the installation depth, the better the window in terms of thermal insulation and other characteristics.
The seal should be: as flexible as possible; durable; do not lose their properties at low and high temperatures (-20 ... + 55 0С); do not emit odors and toxic fumes; do not change colors over time.
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.
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.
Profile drainage holes Thermal insulation properties of the window depend on the number of chambers. There must be at least three of them for cold glazing of balconies, loggias and technical rooms and at least 5 for windows of residential premises, offices, retail establishments, hospitals and schools. PVC profile with 3 chambers PVC profile with 3 chambers. PVC profile with 5 chambers PVC profile with 5 chambers.
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!
types of opening of shutters of plastic windows Deaf windows. Stationary construction of a frame and a double-glazed window. Blind windows do not have fittings and do not open. Most often they are installed as an element of a multi-leaf window or as a showcase. Tilt and turn window. This is the standard and most common type of opening, it is suitable for houses and apartments. The mechanism opens in a horizontal and vertical plane, it is suitable for rectangular, arched and trapezoidal structures. With this option, micro-slit ventilation is possible. Fanlight (windows with a transom). Shtulpovye windows (oar). Their shutters open in one plane and, as a rule, open into the interior of the room. Sliding blocks. Such windows are the right choice for rooms with limited space. They are ideal for glazing loggias and balconies.
What you need to know when choosing a double-glazed window Double-glazed window is 70% of the entire window. In a PVC double-glazed window, the glasses are rigidly fixed, there is a special spacer between them so that the windows are strictly parallel to each other. Sometimes a moisture-absorbing material, silica gel, is placed inside.
The window sill and slopes are not structural elements of the window block and are decorative details. Design features of Exprof windows Correct plastic windows must be equipped with a ventilation mechanism to ensure a constant supply of fresh air into the room, an optimal level of humidity and a healthy microclimate. The frame of exprof Aero breathable windows has a built-in ventilation chamber designed to let in and heat air from the outside while maintaining tightness, heat and noise insulation of the structure.
