The properties of the double-glazed window determine the heat and sound insulation of the window block, as well as the degree of natural light in the room. Fittings play an important role in the usability and durability of the translucent structure. Details such as constipation, clamp, scissors, handle, bar are responsible for the possibility of opening the sashes in different ways.
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.
The REHAU manufacturer presents 7 types of profile systems: Reliable and economical REHAU ECOSOL 60 profile with a smooth surface and a 15° bevel, suitable for the manufacture of standard doors and windows, balconies and loggias; REHAU SYNEGO 7-chamber PVC profile with increased thermal insulation, which makes it possible to produce windows 50% warmer; REHAU EURO 70 standard five-chamber system, which combines good sound insulation, noise and dust protection; New 6-chamber plastic profile with a depth of 86 mm - REHAU GENEO, made of RAU-FIPRO material and having high thermal insulation performance; The REHAU BRILLANT DESIGN luxury five-chamber system with an exquisite glossy surface has increased rigidity due to 1.5 mm metal reinforcement. REHAU KORSA DESIGN 70 - a five-chamber profile system, a joint development of KORSA and REHAU, will ideally complement the interior of your premises and will please with its appearance. Ideal windows for a "passive house" REHAU GENEO PHZ is an innovative product from REHAU. This is a unique 6-chamber profile system with a depth of 86 mm. A special role in the REHAU GENEO PHZ profile system is played by special thermal modules and an integrated middle sealing circuit. achieve such high energy efficiency levels.
Intra-profile ventilation of PVC windows The method of ventilation of a room with closed sashes can be implemented in different ways. Some manufacturers install a slotted, folded or overhead ventilation valve in the PVC profile.
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.
1. The dimensions of the double-glazed window. The widespread use of plastic windows with double-glazed windows necessitated their unification and standardization. Currently, bags are produced in thicknesses of 24, 26 and 32 mm. Profiles of different manufacturers have different seats, so you should choose a double-glazed window, in accordance with this parameter.
Window profile width The wider the profile section (the distance between outdoor and indoor surfaces), the warmer and quieter the translucent structure will be. In a wider profile, you can put a double-glazed window with better thermal insulation and noise reduction characteristics.
Sooner or later, but a sealant working in a stressful mode, which can withstand both mechanical and thermal and chemical influences, the material wears out. It is not difficult to make a replacement even on your own, if you choose a suitable sealant from the entire range of products offered by manufacturers.
Modern wooden windows are equipped with durable "warm" double-glazed windows, they look aesthetically pleasing, but have a couple of significant drawbacks: high price and the need to update the coating.
