Tempered glass is a product that after being manufactured (edges, holes and carving) undergoes a controlled thermal treatment, in which the glass is evenly heated in the tempering furnace, reaching a temperature of about 700ºC. Then, the two sides of the glass undergo a sudden cooling through air and pressure.
With this process, we are trying to achieve a glass with high mechanical and thermal performances, without changing the lighting and energy characteristics of the base product. This process gives the glass a resistance 5 times higher than the annealed glass with the same thickness.
The glass is converted into a high safety material for construction; the resistance is increased and the characteristic of fragmentation into granular chunks is added. The main characteristics of tempered glass are the following:
- Impact resistance
- Flexural and tensile strength
- Thermal shock resistance
- Fragmentation – a particular characteristic of tempered glass, breaking causes the division of glass into small non-cutting fragments, preventing physical risks and accidents.
