Efficient glass energy Some manufacturers of glass products float with special a fine layer in a side that, allows that to the energy of suns the ticket in a direction, while it reduces the thermal transference for the other side. The principle for backwards of this is the difference in the thermal wave length of energy transmitted for the sun and that it transmitted from the heat inside of one room. The special covering, many times, of the one tone has very taken brown or ash for the glass. The covering is not very robust and it would not go to last much time will have been submitted to a normal cleanness or in external climatic conditions - for these reasons, this type of glass normally used only in is stamped double (or triple) units of glasses with special covering in the interior. Standardized (overcast glass) Made from plain glass, this type has one design rolled for a side during the manufacture. It can be used for decorative effect and/or installment of privacy. the shaped glass is available in a gamma of color tonalities, as well as smooth. The variety of models standard is available, each standard has a number of cited distortions normally, of 1 the 5, being 1 very little distortion, 5 being one raised diffusion level.

In external glasses, the shaped side is generally in the way interior that the atmospheric dirt can easily be removed of the relatively plain face external. Tempered (security glass) the tempering glass float after having is produced through the application of a special treatment for common glass been cut and finished. The treatment involves the heating of the glass quickly so that it starts to amolecer (about 620 degrees C) and after that cooling it. This produces a glass that, if broken, if it breaks in small pieces, without sharp edges. The treatment makes to increase the superficial tension of the glass, that can cause ' ' explodir' ' if broken, this is plus a dramatical effect of what dangerous. It is important to notice that the treatment must only be applied after all the cut eo processing was concluded, as a time ' temperado' , any attempt to cut the glass will make with that it to break.
