Double glazing

Double glazing is the most noticeable element of a window and consists of two or more different glass sheets tightly joined together along the perimeter using a frame – a spacer and a sealing component. The area between glasses is filled with air or argon. Depending on the glass types used, the following basic functions of double glazing can be defined:

  • Heat Insulation. It is used to reduce heat loss in a building. Such requirements are best addressed by the glass types with low emissions capability and with soft microwave covering – the Low-E glasses.  
  • Protection from Sun. Double glazing also protects against solar radiation and allows the regulation of temperature in a building under the impact of sun rays, thus optimising costs for air conditioning. For this purpose, tinted glass and glass sheets with special coverings are used.
  • Sound Insulation. Double glazing is also used to reduce the level of noise in a premises. For these purposes, special soundproof glass is used – multi-layer glass where either an acoustic PVB film or a special acoustic resin is placed between sheets of glass.
  • Safety and Resistance to Impact. Safety glass is used to protect health, life or property from different sorts of threats. It is manufactured from several glass sheets which are joined together with polymer film or resin.
  • Fire Safety. In the case of a fire, this glass helps prevent the spread of fire, as well as heat and gases caused by high temperature. Similarly to safety glass, fireproof glass also consists of several glass sheets joined together with a special polymer.
