The glasses are very used in the material present time, houses and store colocameste as a barrier between the interior and exterior of private and commercial seusespaos, but after all what it becomes the glass temperadonum so special glass, which are its characteristics and what odiferencia of remaining glasses. When if a product says of glass if falade that has some characteristics but where some dasprincipais are the fact to allow to visibility for the attached space aomesmo time that creates a barrier that hinders the ticket for this mesmolocal. Maseste glass obtains prominence in some points, to start to podemosfalar of the factor resistance, the tempering glass is a bastantergido glass and this makes with that its resistance the impacts is bastantegrande, mainly when compared with the traditional glass. Outradas its characteristics is on to the form as it reacts the impacts queobriguem the tempering glass to break, whenever this succeeds vidrotemperado if estilhaa in small fragmentos, this fact allows that emcasos of accidents with tempering glasses the possibility of to algumsofrer serious wounds is sufficiently lesser. For its production the glass temperado conceived through machines that have the capacity to control atemperatura of the production of this glass, the glass tempered in the reality effect from the common glass and so that this transformation to possaacontecer the glass is displayed until a superior temperature 500, depoisdurante its esfriamento the tempering glass is immerged into depotssio nitrate, the final result is a glass with a superior rigidity aovidro qu has in our houses. But this super glass has seusproblemas, situations that compel to have some cares, to start ovidro tempering does not allow to interventions for any cut later deestar produced, that is everything has that to be made before its production, places for the screws, fixing, etc. The resistant but fragile bastante glass tempering when displayed the pressure, this is the weakker seulado one, lesser flexibility when it is compared with outrostipos of glasses. Still thus it does not leave of being a glass that muito used for example in places I publish as the stoppings detransportes I publish or same in the telephone cabins, spaces quebeneficiam of the resistance of the tempering glass at the same time that vmdiminudo the danger with the fragmentos in the case them glasses to break.
