Laminated tempered glass.

Laminated-tempered glasses combine the qualities of both types of glass.

Laminated glass consists of the joining of several glass sheets of any thickness, by means of intermediate films made with translucent plastic materials. These films are mostly made of polyvinyl butyral (PVB), ethylene-vinyl acetate (EVA) and UV-activated resins, or simply a mixture of their ingredients.

Its most remarkable property is that, in case of fracture, the plastic film prevents glass fragments from shattering. This considerably improves its mechanical performance in case of impact and avoids the danger of glass splinters being released. This is possible thanks to its sheets or thickness (PVB).

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.

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.
