Tempered glass.

Tempered glass is a type of safety glass, processed by thermal or chemical treatments, to increase its thermal resistance compared to regular glass. This is achieved by compressing the exterior surfaces and tensioning the interior surfaces.

To do this, the glass is subjected to a thermal process of 650ºC, before receiving a sharp cooling of air, resulting in a glass with excellent shock resistance and tolerance.

Tempered glass properties.

Thanks to its special composition, when a tempered sheet of glass is broken by accident, it crumbles into small granular pieces instead of splintering into large jagged fragments. Granular pieces are less likely to cause injury.

In addition, with this type of glass the chances of breakage due to thermal shock are reduced thanks to its high absorption of solar energy. Energy absorption is the percentage of solar energy absorbed by the glass that generates an increase in temperature. This value is indicative of the risk of breakage due to thermal shock. If it is very high, the glass should be tempered.

It is advisable to use tempered glass in the vast majority of glazing requirements, especially in those occupying a large surface area, and in all locations that are exposed to circulation of people or that present a risk of breakage or impact, as well as to different temperatures.
