Vsyo business in a window

The civilisation comes to our houses literally as light - through windows. It sounds a little grandiloquently, but very precisely transmits sense of the told. Actually compare facades of new and old Moscow houses: new - are unanimously issued by double-glazed windows, and old - basically cracked double wooden frames among which window newcomers here and there gleam, favourably being allocated on the general background special smoothness and a whiteness. External European uhozhennost though causes at times envy of some neighbours especialy offended by a life, but, unconditionally, pleases an eye. It is a civilisation sign, more truly, one of them, because the main thing in other. The owners who have purchased modern double-glazed windows, have established not simply new windows in beautiful frames: they have acquired new quality of a life.
If at household level to understand, than qualitatively it is better the windows packed into double-glazed windows and why people pay for their installation the price, comparable with cost second-hand, and sometimes and the new car the following will be received.
- In the house it becomes notable more warmly. The tight design of a double-glazed window does not allow nagretomu to air to depart from a premise on a wind.
- In the absence of cracks in frames in rooms the dust disappears.
- For ever need disappears to repair, paint and caulk frames.
- At the closed windows street noise does not get into the house. It is possible to sleep easy, not being afraid to wake up from a sudden roar of the got car or a tram tinkling sound.
- There is qualitatively new convenience of use. Window shutters can open in several planes, be moved apart or move under different inclinations, have a mode of "winter airing», to be deaf persons, folding, rotary and so forth
- To wash windows begins very simply and easily. It is not necessary to unscrew and screw together frames, peeling fingers about poor painted over tree from which the dirt is very badly washed off.
- Wins external and internal furniture of the house. The design of window covers can be picked up for own taste.
- Double-glazed windows are durable. If they are qualitatively produced and correctly established, it is possible not to recollect their replacement at least years 25, and even 50.
If to the dignities set forth above to add the external reasons connected with consequences of the world energy crisis benefits of application of double-glazed windows become even more obvious. Sooner or later, but also at us will learn to save heat, regulating its giving as it is accepted in the West. New building is already conducted on energosberegayuschim to technologies, and here in old houses it is necessary to be warmed, first of all replacing the basic source of penetration of a cold - windows. It is expensive, but it is necessary to consider, that power consumptions which suppose traditional wooden windows, are that, that their replacement by new double-glazed windows will pay off in some years. To tell difficultly because all depends on a price level on the electric power more precisely.
However to be decided on purchase of double-glazed windows does not mean yet simply to go and purchase. Not so all is unequivocal in the window market. There is a choice problem. Each company in it as, however, and in any other business pulls a blanket on itself, advertising exclusively the goods. It is possible to come across or fakes, or it is simple on the bad manufacturing connected with inexact observance of technology. Besides, double-glazed windows have certain features that is why it is not necessary to be guided by experience of friends and acquaintances which have already delivered itself new windows recklessly. The matter is that under identical weather conditions in the street in each house the microclimate. At someone hot, at someone it is cold, someone has a forced-air and exhaust ventilation, and at someone is not present. To choose a double-glazed window design follows with allowance for these circumstances.

THAT IT IS NECESSARY TO KNOW ABOUT THE DOUBLE-GLAZED WINDOW
Muscovites generally purchase either single-chamber, or two-chamber double-glazed windows in the ratio approximately 50 on 50. The standard single-chamber double-glazed window consists of two glasses with air space between them. The two-chamber double-glazed window includes three glasses. On quantity of glasses and a thickness of a double-glazed window depend it energosberegayuschie and shumoizoliruyuschie properties. The difference in the price at them not so big also makes approximately 10-15 % at account on 1 m2 the areas. And here what of them should be chosen, depends on a microclimate of particularly your apartment.
In overwhelming majority of old houses there is no forced-air and exhaust ventilation. If you live in the house where well heat and there is no raised humidity basically it is possible to stop the choice on a single-chamber double-glazed window. Otherwise it is better not to risk and purchase a two-chamber double-glazed window. The matter is that the single-chamber window with usual glasses mists over at temperature in the street-7, and even-5°S. That it to avoid, it it is necessary to keep all time hardly slightly opened. If the house not so warm, it not an exit. Zamuchaeshsya to run to open and close air schelochku. In a two-chamber double-glazed window the condensate arises at temperature-18-22°S. Recently similar frosts in Moscow happen not so long and often, but all the same happen, and apartment, despite a cold, it is necessary to air often all the same. This defect directly is connected with tightness of a design of a double-glazed window which, on the one hand, supplies a reliable thermal protection, and on the other hand, requires too frequent airing in any weather. Especially unpleasantly this moment is shown in small premises where at closing of access of air it becomes very fast stuffy. In modern building this moment is considered, well and in old houses in case of need it is necessary to establish forced-air and exhaust ventilation system independently. Actually, in the long term it should be arranged in all buildings of a city, differently about any real energosberezhenii cannot be and speeches.
ARE POSSIBLE VARIANTYIM
It is essential to increase heat - and a noise isolation of windows it is possible if to purchase double-glazed windows, in which between glasses zakachan inert gas (argon or kripton), instead of usual dry air. In this case the temperature of formation of a condensate, for example, at a two-chamber package decreases to-30°S, but years through 10 procedure zakachki gas it is necessary to repeat. There is also other variant of increase energosberegayuschih and shumoponizhayuschih window properties. It consists that double-glazed windows can be completed with different glasses.
First, it is possible to vary a thickness of glass: the it more thickly, the more low at it heat conductivity and is better a noise isolation.
Secondly, it is possible to use in double-glazed windows «energosberegayuschie» glasses. Now there are two kinds of such glasses. The first carries the name k-has flown down (firm cover), the second - i-has flown down (soft cover). If in a double-glazed window to replace one simple glass on k-has flown down, teplopoteri windows will very sharply decrease, approximately in 5-6 times. If instead of it to deliver i-has flown down, the effect will be even more striking, as it more than in 20 times will raise teplosberegayuschie properties of the window completed with usual glasses.
Thirdly, it is possible to combine warming variants. The two-chamber double-glazed window with k-glass and with argonovyim filling maintains frosts in areas of the extreme north. Air temperature should be lowered more low-1000S that such windows all the same have started to mist over.
Except windows of wide consumption which basically solve heat and noise questions, there is still a weight of variants of the double-glazed windows bearing different functional loads. It is possible to make a window protivovzlomnyim, bulletproof, pozharozaschitnyim, combined in which one glass protects from the sun, and the second from a cold, and it is possible to decorate with its stained-glass window or decorative glass. All depends on your desires and possibilities because there are such requirements completely not cheaply.

WINDOW PROFILE
In popular speech the profile is, as a matter of fact, a frame in which the double-glazed window is established. The range of profiles is diverse enough: plastic, a tree, aluminium, fibreglass, a tree in a combination with aluminium, etc.

Profile from PVC. For today the windows edged by a profile from PVC, - the most popular. It speaks a practicality and relative cheapness of plastic. He strong, durable, is not afraid neither a moisture, nor the sun, is perfectly looked, accepts at manufacturing any forms and it is easy to look after it. However the problem of a choice and here exists. It is the most reliable to address to firms which sell the double-glazed windows collected from "native" import profiles of firms of repute, of course. In our market they in the majority the German: Rehau, Veka, KBE, Salamander and many other things. The domestic plastic profiles produced on the same (German) technologies, on 15-20 % are cheaper, and too basically very quite good. Only it is necessary to be more cautious at a supplier company choice. It is desirable to visit its office, to have a talk with managers, to secure with recommendations of acquaintances is even better. Differently, it is necessary to use only services of the solid companies which grant the guarantee for a profile for not less than 15 years. Warranties and for installation of double-glazed windows for not less than for 1 year should be besides, necessarily granted.
To speak about cost of the fully completed windows very difficult. It depends after all not only on a profile material, and and from the sizes, a design of a double-glazed window, quantity of shutters, the mechanism of their opening, size of slopes, window sills and other specific features. It is possible only rather approximately, by results of interrogation of several firms, to define a conditional average price of a double-glazed window with PVC-PROFILE as 150-160$ for 1 m2.

Wooden profile. It is a question, of course, not of wooden frames, and about the profiles of new generation produced on modern western technologies. As their basis it is used kleennyiy the three-layer bar previously ideally dried and protected by special oil impregnation under vacuum from rotting. About deformation of such window cover cannot go and speeches. It prochen, is rather beautiful and will quite stay in our climatic conditions of 20-30 years. The profile from PVC can serve much longer but when it will fail, it is necessary to replace it, and here the wooden profile can be repaired anew. One more dignity of a tree, comparison with which will not sustain any artificial plastic, is a natural ability to "breathe". But the prices for windows from a wooden profile bite. They approximately are twice more expensive than plastic analogues. Domestic variants of wooden windows are cheaper, but also quality they, naturally, worse.

Derevoalyuminievyie profiles. Already from the name it is clear, that it is the combined design from two materials, and, it is necessary to tell, very successful. Its idea consists in use of aluminium for protection of a tree against external effects. That is outside of a building the window aperture is framed by an aluminium profile, and indoors pleases an eye a habitual wooden frame. Very practical and attractive variant, but, of course, the elite. The Swedish and Finnish items are most preferable to our region.
