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.
Metal strips are hidden inside the profile and act as a strength enhancer. Sometimes windows of a similar design are called metal-plastic, which is more true than just plastic or PVC. The function of metal inserts is very important to ignore.
But in slightly more extreme circumstances, such as severe frost or heat, as well as direct sunlight (UV), it can fail. Becoming brittle in the cold and softening in the heat, it quickly becomes unusable if the window sash is actively used. But with the doors constantly closed (or constantly ajar, in micro-ventilation mode, for example), it will last quite a long time.
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.
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.
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.
Exprof Aero windows are equipped with a more modern and efficient supply ventilation system - intra-profile. The solution that provides a continuous supply of fresh heated air through the "maze" of channels inside the profile is a patented development of the company. Such a system eliminates the occurrence of drafts, the penetration of noise and ensures maximum energy efficiency of the window in winter.
EPDM seal Ethylene propylene rubber seal is also a fairly durable material, which, moreover, is cheaper than silicone. It can be found on the windows of the middle and highest price categories, or you can buy it yourself. True, it is not easy to replace it yourself, it is better to call the master.
So, what you need to know when choosing a window: If your goal is energy saving, be interested in double-glazed windows (silver coating, argon inside) and window profiles (a large number of hollow chambers) The longer the manufacturer has been on the market, the more likely you are to purchase a quality window that will not fall apart after a couple of years of use Reinforced profiles are more profitable to take than ordinary ones It is highly desirable to take profiles with removable seals (for example, REHAU) It is better not to save on fittings Separate troubles in the form of lamination, profiles of different colors, etc. cost more than standard
If you come across a profile of a well-known company, for example, Rehau, KBE, Scamander, Mont Blanc, Veka, etc., then there is a high probability that the window will be of high quality. And if the design is made from the profile of an unknown factory, then it is hardly worth hoping for something decent. But it is impossible to focus only on the profile manufacturer - the window is a complex structure, the performance of which depends on the interaction of all elements - fittings, double-glazed windows, seals. Only by considering all the components in the complex, you can make a judgment about a particular window.
