Number of air chambers in windows Chambers are voids in plastic construction elements (profiles and double-glazed windows). How many cameras should be in a quality window? The answer to this question depends on the climate of the region where you live and the location of the apartment.

Choosing a PVC window seal Tightness is one of the mainof plastic windows. It is achieved by using special sealing elements that are laid around the perimeter of the doors and prevent the penetration of moisture and cold from the street and the escape of heat from the side of the house. In addition to these functions, the seal is also a good sound insulator, not inferior in terms of sound reduction to the best double-glazed windows.

The most significant criteria are the recommendations of acquaintances or those who have already used the services of a particular company. The following are taken into account: the company's work experience in the market; staff professionalism; the technologies and materials used in the production (and the certificates corresponding to them) the timing of the production of orders; availability of warranties.

Having wondered how to choose a double-glazed window, it is necessary to determine the conditions in which the metal-plastic window will function. Single-chamber double-glazed windows are suitable for glazing balconies and unheated rooms. Windows with double-glazed windows are worth buying for those who value energy saving and need increased sound insulation.

How to extend the life of seals. A gasket made of any material can last several years, or it can wear out in one season. It all depends on the level of service. Even such a seemingly small part of the window requires some care. It consists in periodic (twice a year, in spring and autumn) cleaning and lubrication with silicone oil. If this is not the case, ordinary glycerin quite successfully replaces it.

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!

Fittings Window fittings are not only a handle, but also all the mechanisms located around the main sash, responsible for its movement, fixation incertain provisions.

What technical characteristics of the PVC profile should be taken into account The term "profile" in relation to plastic windows and doors means the material from which the frames and sashes are made. For vertical and horizontal elements in PVC windows, a complex structure made of metal (aluminum or steel) and polyvinyl chloride is used. In cross section, it presents several longitudinal cavities separated by sealed walls. Such cavities are called chambers, the more of them, the theoretically better - the windows become warmer and stronger.

Price The total cost of a window unit depends on the dimensions, configuration, requirements for the design of the structure, the complexity of installation and some other nuances.

Instead of standard glass, an impact-resistant triplex (two or more layers of glass with a polymer film fixed between them), glass with a multilayer coating that blocks part of the sun's rays can be installed in a double-glazed window.
