Availability of certificates For each component of the window (profile, double-glazed window, fittings, components) there is a separate GOST. Manufacturers of materials and products for completing windows must obtain certificates of conformity for their products.
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.
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?
After an approximate calculation on the site, you can choose the nearest offices where you can purchase the company's products, and send them an application that will take into account all the parameters you have chosen.
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.
Decoration of PVC profiles Who produces high-quality profiles Basic profiles, from which window structures are assembled, are produced by several dozen factories in Europe, Russia and the CIS countries. Only one name of the manufacturing company can tell you how to choose plastic windows correctly. But as a finished product, a lot depends on the specific window assembler and its installation. Experience suggests that expensive quality profiles, as a rule, are used by responsible performers who produce excellent windows.
High-quality translucent structures for many years protect the room from the scorching sun, cold and wind, provide optimal humidity in the room, perform protective and other functions. It is important to know how to choose the right plastic windows for an apartment in order to understand which characteristics you need and which ones are not worth paying for.
What you need to know when choosing a window profile The window profile is the window itself, the frame where the double-glazed window is installed. Profile properties usually depend on the material of manufacture. As a rule, this is polyvinyl chloride (PVC), there are also aluminum and wooden windows. In PVC profiles, internal compartments are important, filled with air and sealed with plastic on all sides. Their purpose is the same as that of a double-glazed window: to retain cold with the help of low thermal conductivity. The more such chambers with voids (and the better they are arranged), the more efficiently the window will savebe your warmth.
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.
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.
