How to choose windows

In this article we confine ourselves to the most common double-glazed windows with frames made of plastic profiles, although there are double-glazed windows with wooden frames and aluminum profiles. But nothing but plastic, as the most versatile and economically feasible, provided a variety of brands and designs.
"I want the windows" - with these words apply to the plastic company 99% of customers. "Leave us the size and say that going osteklyat - balcony, kitchen or hall. Our expert will calculate and tell you the price. The removal and installation of add 5 and 15% of the order" - meet him in 99% of cases
It seems so simple: it is important for the firm, how much you take. But for you - what windows you get for your money.
But square meter of glass can do, and at $ 50 and $ 250 - and this despite the fact that prices of materials for the frame, glass or hardware from different manufacturers may differ by less than 30%. The cost is heavily dependent not only on the quality and type of components, but the number of components and configuration of the plastic window. So, this should probably know.
Immediately warned - a good glazing can not be done cheaper. Theoretically, you could do this: order a box of the highest quality components, and save on complex and expensive opening constructions, preferring them to the deaf, which is cheaper at times. But after awhile you realize that the window is washed from the outside is almost impossible, and to use it, when it's bad weather, extremely uncomfortable. You can go the other way: in the window opening will literally everything, and savings will be achieved in manufacturing quality and cost of materials, fittings. Only then you find that disgusting noise insulation windows, it misted, sagged and faded.
The first step to saving money - to find the optimal configuration of the Deaf and the moving parts of your windows.
Further, many simplify the task. By choosing some combination of a profile for the frame window, and, in fact, glass - bought all the windows of the same type. Yes, and sellers are urged on to this: "You will all be the same box."
And if they want the same? On the balcony with large glass windows with a reasonable supply of improved thermal protection, while in the kitchen high heat rejection to anything - better to put a window capable of being reopened as a whole or through a small slit. In the living room you will, for example, want to put zatonirovannye, and in the bedroom - with seats plastic window. At the same owner may have special requirements at all - that was armored glass window film, that had burglar mount and locks, to have had the desired texture of the exterior finish frame ...
Look to the proposed glazing. Outwardly they may look similar, but can be arranged in different ways, respectively, in different ways and cost. For example, the insulation is of great importance thickness specified in the window glass and chamber frame profile (the chamber - an air layer in the profile (frame), prevent the loss of heat as the air between the panes).
Fine European 60-64-millimeter profile does not contain windows that are in need for our cold four cameras, in addition - not suitable for installing glass of sufficient thickness.
To improve the insulating properties instead of air in the space of insulating glass mezhstekolnoe sometimes pumped krypton or argon (these gases are worse than the conduct heat), and using them in glass with heat-reflective coatings. However, the advantages of high-tech insulating glass is easily outweighed by the banal slots in frames or is referred to fine euro-profiles. Yet much more important to conserve heat - the thickness of air layers, the absence of cracks and a 4-chamber frame.
With low temperatures is associated another nuisance. Some plastic profiles with strong frosts become too brittle and can not resist vandals. So choosing a vintage European profiles, be sure to what extent they correspond to our harsh climate on the temperature range.
Some companies offer a fairly thick five-and even six-chamber profiles for insulating glass. However, the chase for more thermal protection does not always make sense - in some cases the best solution is to use outside overhead frames, which increase the number of chambers to the required level. And then not in all areas so it is important always to keep warm.
But insulation is not so much on the thickness of glass, but on other factors: the number of air spaces, of whether it embodies mezhstekolnoe distance are different for each layer, the use of glass of different thickness, the type of glasses themselves (eg, multilayer triplexes better dampen noise ). If these requirements are not met and the glass you have a normal, their thickness and the gaps between them are the same, even the four-glass little help in the fight against noise of the street ... It turns out that thermal insulation and soundproofing need different windows.
For opening constructions, it is important that your profile had inside steel amplifiers, which must be attached all the hardware (and sometimes it happens that the fittings screwed directly to the plastic profile - it quickly breaks down). The very design of the windows should be tight and not too massive, so after a few years does not deform under its own weight. Solid companies offer plastic windows from environmentally friendly materials and ensure their products full warranty support. The structure of PVC plastic profile includes strengthening and stabilizing additives. We inexpensive profiles - are compounds of lead and cadmium. We clean - non-toxic supplements of zinc and titanium.
The latter, of course, expensive. But very cheap profiles can also be formally "clean". But their strength properties and resistance to fading is poor.
Quality production of products is most easily distinguished by the presence of stigma or company logo, which can be found around the perimeter of the frame. The windows of German producers must involve more and a special mark of quality. Most responsible companies in addition to put a personal stamp number on each plastic product and store in its database all the parameters of this particular glass. Here's the translation that the product - just call and call the manufacturer, this number to a few days to get to replace an exact copy.
Finally give advice banal but effective: a look at the documentation.
Not everyone can afford to spend money on prestigious branded and numbered windows from environmentally friendly materials and accessories to the eternal. But then at least make sure the availability of product certificates and licenses to carry out production and assembly work - preferably before you decide to purchase.
