Glazed windows
The principal difference between modern windows from the usual wood - this is just the presence in the design window glass . Not for nothing that the consumer slang windows sometimes substitute the word "windows".
What is glass? Already from the title it is clear that these are separate glass collected by a special technology in a single product - a package.
Suppose you have two absolutely identical glass, they need to stick together so that between the glass formed gap (air chamber). Air chamber in the future will be a heat insulator and provide protection from the cold in the street.
Each glass is glued to the spacer, usually an aluminum tube, which is located on the perimeter between the two panes. The task of creating an air chamber sealed. Thin strip of adhesive composition (butyl) performs an additional function of sealing layer.
However, it is very unreliable design, so there is a need for additional sealing of the package by a thicker layer of sealant (polysulfide). The whole package is poured around the perimeter of this sealant. Two hours later the glass is ready to use.
In short it and the whole technology of glass. To improve the energy-saving properties of double glazing windows several improved. For the Russian climate is necessary to use double-glazed windows, glued together from three panes, respectively, there are two air chambers, which greatly improves the characteristics of the window. Such windows are called two-chamber.
You can improve performance and by using energy-saving windows with special coatings. Today it is cheap technology. In this case, the ability of heat-insulating glass is greatly increased. Thermos effect occurs. Heat, which tends to the street through the windows, energy-saving layer is reflected back into space. Incidentally, in the summer, when outside temperature is higher than in the flat, the glass will prevent the penetration of excess heat from the street.
Another way to increase energy-saving characteristics of the window (glass) - to fill the chamber between the panes with an inert gas such as argon.
