Double-Glazed Windows

If it is important for you to rationally consume heat in the winter season in order to protect yourself from unnecessary external noise and not to think about windows that leak, then you can choose the best option in the company VEFASISTEM, which will help maintain an ideal climate in your home.

Single-Chamber Double-Glazed Window

It consists of two glasses separated by a distance, it can be either plastic or aluminum. These double-glazed windows are suitable for an office or administrative building, for apartments with windows or doors facing an already glazed balcony.

Double-Glazed Windows

It consists of three glasses separated by two distances in a sealed system. The formulas of insulating windows can be very different. An important property of these double-glazed windows: the distance between the glasses should be different. A double-glazed window lets in less light and sunlight, but it will not be noticeable to the naked eye.


Advantages of thermal stations, or why is this distance called “warm”?

  • The thermal conductivity is 950 times less than that of the aluminum distance.

  • Reduces the risk of the effect of fogging windows at the edges.

  • The polymer distance reduces the heat loss of the double-glazed window in the marginal zone.

    To a large extent, it prevents the occurrence of condensation and ice, the appearance of which causes extremely undesirable mold in the house and dangerous to health.

  • It helps to maintain the tightness of double-glazed windows for quite a long time.

  • The sound insulation of double-glazed windows is 18% higher, in comparison with analogues with a distance of aluminum.

  • Double-Glazed Windows equipped with a polymer distance have increased shock resistance and are able to withstand stronger household shocks than double-glazed windows with an aluminum distance.

The most “vulnerable” place in the window, in terms of heat loss, is the edge zone in the Double-Glazed Window. Most often, manufacturers install aluminum remote frames in Double-Glazed Windows. They conduct cold and reduce the temperature of the glass on the inside of the window. Based on generally accepted standards, the heat transfer resistance in window structures is determined with a correction factor that takes into account heat loss in the area where the glass adjoins the remote frame (edge zone).


Energy-saving glasses got their name because of a special optical low-emission (or energy-saving) coating that is applied to the surface of ordinary transparent glass to increase its energy-saving properties. This layer transmits infrared radiation (direct solar heating rays) into the room, while simultaneously “mirroring” long heat waves (for example, heat from heated radiators). In other words, energy-saving glasses let solar heat into the room, but do not let out heat from heated objects, returning it back.


With the help of safety glass, glazing works are carried out:

  • External and internal walls of buildings and structures
  • Special windows
  • All-glass doors
  • Places with a high risk of mechanical or thermal damage
  • Also made of Triplex:

  • Glass products

  • All-glass structures
  • Enclosing structures (partitions, windows, all-glass doors)
  • Glass staircases of administrative buildings, shopping complexes
  • Shop windows and facades of buildings

Laminated glass consists of two or more layers glued together with a special film or composition at high pressure and high temperature. This design determines the protective properties of the glass – it becomes shock-resistant, but if it still breaks, the fragments do not fly apart, but remain on the polymer film. The scope of application of triplex glasses is very wide – from the entrances to the building to the interior elements.


In other words, it is called “smart glass”. Thanks to innovative technologies in production and the use of non-standard solutions, it provides reliable protection from the sun, condensation does not form in such windows, they transmit light well and perfectly retain heat indoors.
