Safety tempered glass (ESG)
Thermally toughened soda lime silicate safety glass – glass, which has been controlled process of heating and cooling caused by the permanent surface compression stress to substantially increase its resistance to mechanical and thermal stresses and to obtain prescribed characteristics disintegration.
Main parameters of tempered glass
- resistant to temperature changes, shock, characterized by a greater flexural strength
- glass is 4 times stronger than conventional flat glass
- thermally toughened glass is known as tempered glass
- when broken glass crumbles into small pieces that will not hurt you
- designed for interiors
- glass is defined by norm ČSN EN 12150
Glass thickness: from 3 mm to 19 mm; max. side propotrion: 1 : 20
Size for production: min. 250 x 100 mm, depending on the thickness of glass and processing max. 6000 x 3210 mm
Thick glass: 15 mm max. area 16 m²; 19 mm max. area 13 m²
Maximum tensile strength in bending
Thermally toughened glass (tempered glass) by norm ČSN EN 12150 shows during testing 4 mm thick glass panel toughness 120 N/mm².
Concrete construction safety must be assessed comprehensively the intended mode of use of glass. Tempered glass provides protection against injury, e.g. in the following cases:
- showers
- glass doors
- glass partitions
- furniture glass
- facade glass
- balcony glazing

Nontempered glass
When broken glass creates a dangerous long saber with very sharp edges.Semitempered glass
When broken glass is broken into smaller pieces, they are dangerously sharp edges. Glass has a higher strength, but it is not a safety glass.Tempered glass
Glass shatters into small pieces with fuzzy edges. Tempered glass is safety glass.OGB Use
Glass doors
Sliding doors always must be made of tempered safety glass.Interior glass
Safety glass should be used in the interior standardy.Spot saved glass
If there are holes or slots in glass, we recommend using a thermally hardened.Frameless railings
Frameless safety railings are made from laminated thermally toughened safety glass. More...
