Rebate distance Is PVC profile wall thickness so important? When deciding which plastic windows are better to choose, it is necessarypay attention to the thickness of the outer walls and partitions. If the outer wall is thinner than 2.5 mm and the inner wall is 2 mm thin, then such windows are only suitable for an unheated garage, warehouse or workshop. In a residential building, they are of little use, in the sense of protection from the cold. In addition, it is possible to assemble a relatively small structure from such profiles - in addition to their low intrinsic strength, the walls do not allow fastening powerful fittings.
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!
There are several basic modifications of seals that differ in some properties and, of course, in price. The most common are: Thermoplastic (TPE). Thermopolymer (EPDM). Rubber. Silicone. Let's consider them in more detail.
What fittings for plastic windows are better? Professionals advise choosing only products from well-known manufacturers. Cheap low-quality analogues can quickly become unusable.
Order a free call Selecting the type of sash opening When choosing plastic windows, you should decide on the type of sashes. They determine the functionality of the design and comfort during its operation. The type of sashes must be selected depending on the size of the structure, how many windows are in the room and whether there is a need for regular ventilation.
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.
Choice of accessories and equipment When choosing accessories for windows, you should pay attention to their material, colors and functionality. You can choose metal-plastic windows and order roller shutters, blinds, mosquito nets for them. If necessary, window sills, slopes and ebbs can be added to the package.
Reinforcing profile PVC insert By itself, polyvinyl chloride, even modified with chemical additives, is not a very strong material mechanically, moreover, it is prone to thermal deformation. But in combination with metal inserts, its stability and resistance to mechanical stress increase by an order of magnitude. It is more reliable to fasten all the fittings to the metal, which is quite a lot in a modern window.
To reinforce the plastic profile, special steel inserts are used, which are mounted directly into the main chamber of the PVC profile. The thickness of steel reinforcement in translucent PVC structures according to GOST should not be less than 1.5 mm.
The quality of the product is guaranteed by the reputation of the manufacturer. Among the cult types of fittings are products of the following brands: MACO (Austria) - high protection against premature wear and corrosion due to wax and anti-corrosion spraying Winkhauz. Represented by a wide range of rotary, sliding, combined systems, handles, locking devices, hidden elements; ROTO (Germany) - zinc coating is used for corrosion protection. High load capacity (sashes can withstand a weight of about 150 kg), a wide range of designer handles, locking systems, opening modules, etc.; REZE. (Turkey). Docking system of connections for convenience of installation. Burglary resistance. Aesthetic appearance. Recommended for completing windows installed in rooms with high humidity.
