Insulating glass consists of three or two glass plates separated by two or one cavities of air hermetically sealed. The thermal insulation capacity of this type of glass, often the so called superwindows, is far superior from the conventional glass, of single glass plate. The decorative possibilities for this type of glass are also unlimited. The cavities can be filled with a variety of elements or objects.
Technical characteristics
The cavities insulating glass are filled with air or even gases such as krypton or argon (much better). Insulation can even be improved by an addition of low-emissivity coating on the inner side of the cavity. The coating consists on a very thin silver coloured foil, which diminishes the heat exchange between the warm inner pane and the colder outer pane, and so increasing thermal resistance. Another technique is to fill the cavity with vacuum, but for this effect it may be necessary extreme care cause the glass as tendency to break under the process because of the pressure.
Other heat-absorption techniques may be added to the glass. The glass cavities can increase their heat absorption by the insertion of adjustable aluminium louvres, glass or plastic tubing and a variety of metallic meshes. This additions, according to the taste may also acquire aesthetic qualities.
Application
Used exclusively as a thermal insulation for façade openings.
