Glass is used in the construction for a long time. This building material is hard to replace, because it’s - transparency. Glass - the main part in the construction of the glass units, the characteristics of which depend strongly on the characteristics of the glass. In the production of glass units is used as a transparent and tinted glass, with hard and soft low-E coating, wired and patterned glass, as well as tempered and laminated glass. For insulating glass units MEDALPAS uses only high-quality glass of well-known manufacturers - PILKINGTON, GUARDIAN, AGC and SAINT GOBAIN.

    Basic codes of the glass:
  • M ordinary window glass, obtained by extraction
  • F window glass, a float-way
  • K glass with a solid low-E coating, obtained by On-line technology
  • I glass with a soft low-E coating, obtained by Off-line technology
  • S Glass, tinted
  • Pl heat reflective film

Tinted glass

Made of raw materials, which are added various substances to produce the desired color. The most common are color-intermediate between the bronze and brown, gray, green and blue. It is possible to produce glass and other colors. Tinted windows are also known as sun or absorbent glass, such as glass absorbs (absorbed) by themselves, more solar heat and light than conventional transparent. Always remember that a light transmission of these glasses is lower than transparent.

Clear glass provides high transmittance of sunlight and heat. This means that in the room where the window is inserted clear glass, will be light and very hot in summer. Colored glass can store window transparency and reduce the amount of solar heat in the room. On the other hand, the glass absorbs the heat is more than clear, and therefore can be destroyed by thermal overload .. Therefore, the use of colored glass in a hot climate requires their mandatory hardening or edging, which increase the mechanical and thermal resistance of the glass.


The defining idea in low-emission technologies is a coating on the surface of float glass of conductive coating of non-ferrous metal or semiconductor oxides containing free electrons. Through conductivity and interference phenomena caused by the presence of free electrons in the coating can be prepared glasses, designed to perform the following functions:

  • reduce heat loss by placing reflection of heat waves in the infrared range
  • r
  • eflection of solar radiation
  • protect the premises from the electromagnetic radiation and radio waves
  • reflection of radiation in the visible range

Tempered glass

When using translucent glass designs where safety is critical (glass roof, sloping glazed facades, the first floors of buildings, office partitions, etc.) tempered or laminated glass is used. Hardening process called heat strengthened glass, based on the specifics of its physical properties. As noted, the glass on the temperature scale has no definite melting point at which it would pass from the liquid to the solid state. So it can be heated to a temperature slightly above that at which the molecules are in a viscous fluid, still capable of plastic shear without the appearance of internal stresses. If the glass is heated so that the entire stock had the same temperature (600 °C), and then rapidly cooled, it hardens the surface, while the inner layer still remain pliable. With further gradual cooling an interior hardens. However, it can not contract with the same force as before hardening. Thus the outer layers of his coming in the heat of compression, and a state of internal tension. As a result, the glass is formed voltage system, ensuring its high mechanical and thermal strength than ordinary glass. The destruction of tempered glass breaks into small round pieces that do not have sharp cutting edges.

Laminated glass

Under the general term lamination understand manufacturing multilayer structures made of glass with PVC film or a special fluid-like material - resin, and thus produced structures called laminated glass. Laminated glass can be composed of several layers of the same or different in thickness and type of glass, which can be straight or curved, in accordance with a given shape. The thickness of the laminated glass depends on the number of glass panes and their thickness, and the thickness of lamination layers.

The most common type of laminated glass used in window construction of different classes of security, is the so-called triplex design of two laminated glasses and intermediate layer. In some cases it is possible sticking film on the glass with one hand, the so-called one-sided lamination. The main advantage of multi-layer laminated glass constructions is the safety of the destruction. Since the destruction of broken glass are hanging on the elastic film, there is no danger of broken glass that could cause injury. With the lamination can be made structures that can serve as windows to protect against hacking and blast, as well as bullet-proof, shockproof and fireproof glass units. Laminated glass is also protected against UV radiation. It should be noted that the lamination (as opposed to quenching) does not increase the mechanical strength.


Increased safety requirements and a systematic shock are resolved with so-called reinforced glass. Reinforced plate of glass in the middle of which is parallel to the surface is placed horizontally rolled welded light metal mesh with a mesh of rectangular shape. Reinforced glass surface of the sheet are usually forged, one of the surfaces can be patterned or corrugated. Reinforcement does not increase the mechanical strength of the glass, and even reduces it by 1.5 times, but the grid does not allow the pieces of glass to scatter and fall out of the bindings for mechanical damage, as well as at high temperatures.

Patterned glass

Patterned glass is produced by means of horizontal steel and having on one or both surfaces a clear regularly repeating pattern 0.5-1.5 mm in depth. Patterned glass provides full or partial scattering of incident light, and has a high decorative qualities.
