Tempered glass

Veneto Vetro is equipped with a high-performance full-convection tempering oven, ideal for tempering new generation, selective, low emission glass that can be tempered with very low remission.
The flat glass is laid on a roller table where it slides into the oven that heats it to the tempering temperature of approx. 640°C, after which it is rapidly cooled by air jets. This process cools the surface layers and hardens them, while the inner layer remains hot longer. As the centre layer cools down it generates a compression force on the surface which is balanced by the relaxing tension inside.
Tempered glass is about six times tougher than float glass, because the surface faults are “closed” by the mechanical compression tension, and the inner layer has fewer faults that could generate cracks.
Given its greater strength, tempered glass is often used to construct components without a bearing structure (all glass), like glass doors and structural applications.
It is also considered as “safety glass” because, besides being stronger it tends to break in very small rounded fragments that are not dangerous. Consequently this type of glass is ideal for sliding doors, main entrance doors to buildings, for bathrooms and showers, for internal partitions and all those uses where high-strength glass is required.
The tempering process and features of tempered glass are subjected to the UNI EN 12150 standard, while the UNI EN 7697 standard governs the safety criteria for glazed applications.

Maximum size in 2600 x 5700 mm
