In an atmosphere TRANSPARENCY
Glass - a material illusion. As, as a mirror. It gives sometimes very unexpected effect, the ability to focus, the game of provocation: it is possible to instill: glass - water and wave or wind or air and light and the rainbow, or - what does Glass no. Because the " solid amorphous mass impervious to liquids and gas, which occupies an intermediate position between the liquid and kritallicheskim substances " It can do everything. Color, shape, texture and size - any. The hollow, blown, in sheets, cast, pressed, carved, engraved, sandblasted, milk and bottles, flaming, quartz and uviol, optical and tempered, kronglass and glaze millefori, retichcheli and crackle - enumeration and description of the types and purposes occupy two pages even in terse encyclopedia.
We are so accustomed to the glass, it seems as if it has always been. It really is one of the oldest materials. Archaeologists have found in Mesopotamia Glass beads that are approximately to 2450 BC. But the simple clear glass in our homes civilization was long and winding path. It changes over time, not only technology of its production, but also the composition. Today, besides the main components: sand, soda ash (Na2 CO3) or ash, as well as chalk, dolomite, alumina, it can be added more than 20 other substances. Depending on which the glass acquires a new and wide variety of properties. Now it has become a familiar and reliable construction and finishing material. And varieties of it now innumerable. If you wish, you can even walls and floors of it to do.
Energy saving (thermal protection) Glass is now at odds with a bang in the world. And not without reason. In winter, energy-saving windows retain heat in the summer - cool. It is estimated that because of them manage to reduce the costs of electricity by about 30%.
Tinted, colored and mirrored glass. Very popular now tinted (with a touch of brown, green, etc.), color (a bright saturated color) glass and those with a mirror effect. On the mirror is applied thin film of silver, the color is created by using a film or by the addition of a dye to the batch. Tinting is done as follows: elapsed annealing glass again heated to 600-700 degrees, then spray applied to the special solution film-forming salts. As a result of chemical reactions on the surface of the glass formed thin (1 micron) transparent film (metal oxides). This film can be: conductive, radioprotective, heat absorption (blue) heat reflecting (blue), absorbing the UV rays (yellow), SLR (film titanium oxide) sunscreen (blue) - of ferrous oxide, decorative (Green), etc. .d. There are films that have just a few properties.
The effect of such a wonderful glass: no one sees you, but you can see everything that happens on the street. Such glasses, we often see on the facades of banks offices, hotels. Their appearance creates an image of reliability, well-being and prosperity. But the tinted and colored glass, which makes glass doors and walls inside the premises, give the interior an easy intimacy and eccentricity, leaving scope for the imagination of designers.
Tinted windows are worth an average of $ 5.5 - 50 per 1 sq.m. Color $ 3.5 - 35 per 1 sq.m. Mirror $ 16 - 95 per 1 sq.m.
Figured glass are for people with imagination, which are not satisfied with the bare plane. Traditional patterned glass obtained by the method of rolling the glass is still hot sheet through the raised rollers. But there are other methods of treatment. For example, the pattern similar to the " frost " glass do so: the silicate glass is applied to the adhesive and then placed in an oven. Interesting and birth process patterned glass " ". blizzard Under cools plastic glass mass allowed the air that, knocking its way, leaves embossed on the glass wave.
The surface of the patterned glass can be decorated with a variety of ornaments. Now in Europe, for example, very fashionable glasses with fine geometric patterns. This new technology, and so these glasses are four times more expensive than conventional patterned. Traditional patterned glass cost an average of $ 2 - 15 per 1 square meter.
Safe and durable glass are designed for public places where many people tolchetsya. Most " old " among them - wired glass, within which runs a metal mesh skeleton. It turns out very simply: the metal mesh together with the glass is rolled between the rollers. It looks, I must say, not really, but be sure - do not scatter the fragments in different directions. For example, wired glass in doors put prikvartirnyh halls. And although it is considered a professional already past century, still enjoys demand: the inexpensive and safer than usual. It should be wired glass averaged $ 4.5 - 20 per 1 sq.m.
Tempered glass is more resistant, than reinforced, and 10 times stronger than usual. " tempering procedure " carried out as follows: immediately after the hot glass manufacturing rapidly cooled with cold air. As a result, he fears neither cold nor hot. If, for tempered glass good move, it will crumble into many glass fragments, crumbs. But since there are no sharp edges, they are virtually harmless. So, it was tempered glass used for the " glass " cars, buses and other transportation, entrance doors and partitions.
But the most reliable and safety glass still triplex. The technology of its production about next. Between the two glass sheets are placed plastic foil and placed in an autoclave. At temperatures above 100 degrees polymerized film and the adhesive and joins the two sheets. The strength of laminated glass on strike 12 times strength of conventional sheet glass. We must try to break it. If this happens, and then the pieces are not splashed in all directions, and hang at the intermediate film, without causing harm. If the film is colored, the triplex turns color. Looks like a laminated glass monolith, no layers is not felt. Triplex absorbs heat or light and sound. It should be laminated on average $ 30 - 40 per 1 square meter.
Protective glass . Films of the polymer is not only possible to glue two windows, but also more. From such a laminated glass stairs, and even do floors. To beat them, you not only have plenty of time, but uncommon force. These glasses have an international classification. Glass Class A (protection Vandalism) give a crack, if only to him a few times on a good hit with a brick. There are such glass $ 30 - 120 per 1 sq.m. Class B (protection of penetration), they need something more serious than a brick, for example, a sledgehammer. It is estimated that, perhaps, from the 70th to break a strike glass still possible. Incidentally, owners of expensive mansions, do not want to disfigure Window bars, put these glasses. The price of these glass $ 160 - 300 per 1 sq.m. Protection class - bulletproof glass. They cost from $ 150 to $ 1,250 per 1 sq.
We add to the above that in the world today there are so many different kinds of glass products for the: fiberglass, glass, fiberglass, stekloprofilat, liquid glass, gidrostekloizol, the use of which in the interior we have yet to tell.
The essence of the glass, brittle and ideally invisible - protection. It protects against the world and at the same time opens up in front of you the whole world. In fact, the entire evolution Glass went to to make the home secure and at the same time as open. The case of professionals - find balance, harmony, security and openness home and his soul, that you can now create innumerable ways
