Insulated glazing

The Russian Glass Company today offers insulated glass units of any level of complexity using different types of glass - double and triple glazed units, traditional geometric shapes, with decorative layout, with digital printing, with energy saving, solar protection, multifunctional, tempered, curved, laminated, fire-resistant glass.

An insulated glass unit is a volumetric product consisting of two or three glass sheets connected to each other along the contour by means of remote frames and sealants forming hermetically closed chambers filled with dried air or other gas.

For the manufacture of insulated glass units, RGC uses in its production, in addition to ordinary float glass, special glasses with coatings that differ from ordinary ones in such indicators as light transmission, light reflection, solar factor, emission coefficient, as well as color.

As necessary, in compliance with the requirements of building codes and regulations, glazing safety standards and design specifications, glass in insulated glass units manufactured by RGC can be tempered, heat strengthened, laminated; special fire-resistant glass can be used. According to the customer's requirements, glasses can be mollified, painted to obtain enamelite, a pattern can be applied to the glass.

Packaging of insulated glass units with glass of different properties and thickness, changing, if necessary, the number, width and gas composition of their internal chambers are selected for each facility to be glazed in compliance with its intended purpose. Depending on the availability of special glasses and components, insulated glass units solve different problems:

● Heatsaving

● Sun protection

● Multifunctionality

● Noise isolation

● Safety

● Fire resistance

● Decoration

The production complexes of JSC RGC are equipped with the latest high-precision production lines for the production of insulated glass units LISEC (Austria).

Recommendations when ordering

The allowable size of an insulated glass units, the rating of glasses used in an insulated glass unit, recommendations for heat treatment of glasses in each individual case of glazing determine the operational loads to which it will be subjected during use. Operating loads include:

1. Mechanical loads

2. Climatic loads

3. Thermal shock

1. Mechanical loads on glass - impacts with hard, sharp, heavy and "soft" objects; as well as loads under firearms or ammunition. To prevent the destruction of insulated glass units due to this type of load, safety glasses are used.

2. Climatic loads on glass - loads that glass and / or products made from it for construction purposes are subjected to when exposed to the strength and speed of wind, snow mass, fluctuations in temperature and atmospheric pressure, and solar radiation intensity.

During operation, stresses in insulated glass units are caused by the action of a one-sided load: wind and snow (for translucent roofs), or a two-sided load due to changes in atmospheric pressure and air temperature.

Scheme of the spatial operation of insulated glass units under the action of operational loads:

   a)               b)              c)                                 d)

a) insulated glass unit during production

b) one-sided load (wind and snow) on a double-glazed unit

c) double-sided load (atmospheric pressure and outdoor temperature drops) on a double-glazed unit

d) double-sided load on a triple-pane unit

In this case, the stressed state of the window unit glasses largely depends on the air temperature in the space between the panes, therefore, it changes throughout the entire life of the insulated glass units, starting directly from the moment of manufacture and installation at the facility. With the correct choice of the formula and design of the insulated glass units, climatic loads are not the cause of its destruction. In the case of an incorrect choice of the insulated glass unit formula, they can cause depressurization of the insulated glass units and glass destruction.

3. Thermal Stress

With significant temperature differences between different areas of the glazing, not tempered glass may be destroyed due to thermal stress (shock). When heated, glass expands; this is not dangerous if the temperature rises evenly throughout the sheet. However, if a part of the glass remains cold, it prevents the heated parts from expanding. This leads to an increase in tensile stresses, which can exceed the mechanical strength of the glass. If such a risk exists, the glass shall be tempered or thermally tempered.
