Strong and safe glass

Quite often, it is widely believed that the safest glasses are glasses that do not break at all or break without the formation of a sharp cutting edge. Such conclusions are fundamentally flawed. Only glass with internal reinforcement, tempered or laminated shatterproof glass is fully safe.

Strong and safe glass

Glass with internal reinforcement is a sheet-shaped glass sheet with a wire mesh insert that runs parallel to the sheet.

Such glass, if the integrity is violated, does not give flying fragments, due to the presence of reinforcement. There are various types of such glass, including patterned glass. The fittings, as a rule, are made of low-carbon, high-quality steel GOST 7481–78. Reinforced glass is also used to ensure fire safety in various rooms as a glazing material..

Tempered glass is a type of glass that has undergone a special heat treatment – tempered or tempered. This procedure increases the strength of the glass by several orders of magnitude due to the correct distribution of internal stress. The impact resistance of such glass cloth is quite high. 5mm glass is able to withstand the impact of an almost kilogram steel ball from a height of one and a half meters. The peculiarity of tempered glass is that when broken, even small fragments form non-cutting blunt edges. After the tempering procedure, all glass properties (light and thermal conductivity, frost resistance) remain unchanged.

Strong and safe glass

Tempered glass, both straight and bent, is widely used. When glazing all types of transport, in construction, as panels of large sizes (2500 mm) – these are various partitions, fences, doors, ceilings, floors, windows, etc. Such varieties are made: transparent, opaque, matte, patterned, etc. Large stained glass is also called stemalite.

Laminated or laminated safety glass is made from several glass sheets. They are connected using an organic transparent elastic film that glues the glass together. The most common is considered to be three-layer glass that does not create fragments, or triplex. Thanks to lamination and tempering, its strength increases significantly (in comparison with ordinary glass), and the glass becomes safe.

Lamination of glass cloth is the process of joining glasses with a PVB film – butafol-polyvinylbuteral, laid between them, by compressing them, when exposed to vacuum and high temperature. The resulting glass can withstand high mechanical loads, has a great shock-resistant balance, and retains fire resistance and optical properties. Safe glass cloth is used for various purposes. It:

  • glazing of facades;
  • as light-penetrating ceilings;
  • glass-fiber windows, roof and doors;
  • glazing of balconies and loggias, greenhouses and greenhouses;
  • intermediate partitions;
  • glass doors and furniture shelves;
  • shower cabins or walls;
  • glass for telephone booths and kiosks, all kinds of shop windows;
  • panoramic glass for elevators;
  • glazing of various premises and underwater structures.
