A from our window the area is not audible any more

Since January, 1st of this year with good reason it is possible to name usual wooden windows engineering of last millenium — now them use only for country houses, even in the cheapest Moscow new buildings plastic double-glazed windows (the truth, the Belarus production) are put. And in old houses many tenants change windows on plastic at own expense.

Let’s understand to begin with, whether reasonably such decision. Or, maybe, business is simple in a fashion?

Heat, is cosy and is durable

Actually, plastic wndows (in a scientifically way the material of which frames are done, is called as polyvinylchloride — in abbreviated form PVC) surpass usual in all parametres. They supply complete tightness — differently, whatever there was in the street an icy cold, whatever force there was a wind — inside will not filter a uniform stream of cold air. Besides, windows from PVC supply fine warmly - and a noise isolation.

The second dignity of these windows — they do not require any care. Wooden as we know, it is necessary to tint time in some years. That them to wash up, it is necessary to unscrew frames. At last, every autumn it is necessary to stick usual windows with a paper, to hammer in cracks cotton wool. With plastic windows it is not necessary-che th! Only periodically to wipe a rag. Thus the good window will live not one decade — warranties, for example, German firm REHAU on the profile makes 40 years.

Thirdly, plastic windows are beautiful. Usually a frame do white, but any colours (smooth or with imitation of valuable breed of a tree) are possible. Along with usual glasses installation tonirovannyih, mirror, figured is possible…

At last, windows from PVC are harmless! To the one who nachitalsya newspaper articles about harm of plastic, about unconditional advantages of a tree, it can seem improbable, but it is the fact. Think that polyvinylchloride is allowed to application in many areas where its contact to a human body is much more closely — electric kettles are done of PVC, packing for yoghurt, plastic bottles for drinks. Recollect and that the tree (which always moves as a certain antipode, the ecological compatibility standard) will be necessarily covered by a paint, and it is 100 percent chemistry.

But, maybe, there are any else modern windows, except the plastic? Is. These are wooden (on modern technology not to confuse to typical "fire wood"), aluminium, stekloplastikovyie… They too are good, but, unfortunately, is more expensive some PVC, and in times. In a word, on a parity the price/quality to polyvinylchloride of competitors is not present.

But, of course, the window from PVC will prove to be from the best party only in the event that it is manufactured by the solid manufacturer and correctly established.

As it is arranged

The main thing in a plastic window — a profile — from what frames and shutters are produced. A profile — hollow, possessed in emptiness are called as chambers. Their quantity can be from two to five, but for our climate the minimum considers three chambers. Optimum — four (five — already the expensive). About quantity of chambers it is necessary to ask sellers, but approximately to estimate it is possible and on a thickness of a profile. For example, Ministry of Health of the Russian Federation has forbidden to put in the design medical institutions which thickness is less 80 mm as they badly save heat.

The major indicator of a profile — quantity of things in common of a frame and shutters. In this place at window closing chambers too are as though formed, and their number also should be not less than 3-4. To define quantity of things in common it is possible on sealants (rubber linings), going on frame perimetre. By the way, take an interest at the seller, whether there is in sealants a kapron thread? If is not present, in a frost rubber can be compressed, forming cracks.

Besides, in a profile there should be a metal loose leaf for design strengthening. It is better, if it is made not of sickly aluminium, and a strong steel.

One more element of a window — a double-glazed window. As this word is called the design from two or more glasses connected on perimetre by a framework. The double-glazed window differs from a usual window that a framework tight. More often in a package there is usual air — only dried that in a cold season on an inside there was no condensate. For the same purpose in a double-glazed window place silikogel — a powder, capable it is good to involve in itself water steams.

The double-glazed window takes the large part of the area of a window, therefore from its characteristics to protect a premise ability depends on a cold and noise. What it is possible to make, that it protected better? First of all, to increase quantity of glasses. If their two — the package is called as single-chamber, three glasses (air layers it is received, accordingly, two) — two-chamber. A two-chamber double-glazed window — a limit reasonable, bolshego quantities of glasses do not do.

Well the increase in a thickness of a double-glazed window influences isolating properties of a window. The thickness standard single-chamber happens 20, 24 or 32 mm, two-chamber — to 42. Also, though and to a lesser degree, quality depends on a thickness of glass. Standard — 4 mm, but it is possible to deliver and thicker glasses.

At last, developers constantly work on improving air being in a double-glazed window. It is possible to replace it with inert gas argon — from this quality of a window improve. But argon very flying, and at poor-quality manufacturing of a double-glazed window in one and a half-two year it is completely replaced with outside air. Other technology which has appeared rather recently — a double-glazed window with the lowered pressure inside. And that glasses were not pressed inside by atmospheric pressure, applied microscopic rasporki. They, unfortunately, also are Achilles’ fifth system — to make rasporki absolutely imperceptible is not received yet, numbers of points with an interval in 3-5 sm are visible approximately from metre.

The important property of a window — as it opens. Can in any way — then the window is called as "deaf person". This variant, clearly, the cheapest, and firms in the advertising like to use it. If it is written, that windows stand from $50 for sq. m is just and there is not opening window.

Opening can be one-plane — along the vertical party as at a usual window, or along horizontal is is called as a transom. Such windows at solid manufacturers stand around $120 for sq. m. Desire to make opening two-plane will manage to the customer in $150-200 for metre. Still there are sliding windows, but it is faster for ostekleniya than loggias. Other variants of opening (for example, the shutter turns around the of the central axis) meet very seldom.

Useful details

Standard PVC-PROFILE — white colour. The majority of clients such also choose. But it is possible to make and colour. The cheapest method — lamination, i.e. cover by a film. It is possible only from the inside, it is possible from both. Lamination increases the price of a window for 10-20 percent. A better variant (is more durable and will not be) — to paint over white end faces plastic «in weight». From it the price increases already percent on 25-30, and such orders are individual today.

About opening. A "deaf" window — not so such utterly worthless variant as it seems at first sight. Practice shows, that usually people open in a window one-two shutters, others do not use never. Having thought and having made a part of shutters "deaf persons", and a part — opening, it is possible to save many money than if to arrange for all elements of a window two-plane opening.

Let’s pay attention to glasses. Besides usual, exist also so-called «nizkoemissionnyie» — with the lowered factor of a heat transfer. In the winter it does not allow heat to leave a premise, in the summer — it is a lot of to get into it. The most widespread glass of this type — k-glass. Outwardly from usual it differs the big reflecting effect — differently, in it you will see yourselves more accurately, though and not as in a mirror. K-glass also can tonirovatsya in different colours — bronze, grey, green, blue. The last years there was more perfect updating — e-has flown down, having still bolshey reflecting ability.

That the window resisted to blow, it is possible to use triplex — the glasses stuck together in some layers and protective films. At glass blow fight, but remain on a film. Triplex possibilities are diverse — that are not afraid of a football, that maintain a shot from podstvolnogo a grenade cup discharge (it is called as armour glasses). In the latter case, the truth, will not sustain already PVC… In general, for those for whom it is necessary, exist special designs — the armour doors executed, as doors in bank safes (outwardly, by the way, very elegant — anything heavy), be well matched for them and glasses. The price, the truth, — from $700 for sq. m. But is not so plastic windows, and absolutely other history…
