Double-glazed windows for translucent facades

The perfect balance of aesthetics, comfort and building protection

Types of double-glazed windows from OP NII PKD

Soundproof double-glazed window

Noise-insulating double-glazed window
To enhance the soundproofing properties of our double-glazed windows, we:

  • We use two chambers in the design;
  • We use glasses of different widths at the same distances (asymmetric double-glazed window);
  • We use thicker glass for better sound insulation;
  • We use spacers of different widths in one double-glazed window;
  • We monitor the tightness of all joints;
  • We provide the maximum density of closing of shutters.

Multifunctional double-glazed window

A distinctive feature is the combination of sun protection and energy saving factors in one window
The basis of a multifunctional double-glazed window is glass with several layers of sputtering.

  • Each layer has its own key task:
  • The top and bottom provide the penetration of light rays and the specularity of the glass. In addition, they affect the color;
  • The main layer contains elements of silver that reflect heat both into the room and out;
  • Layers designed to protect, give strength and resistance to damage of any type.

Energy-saving double-glazed window

Low-E double-glazed window
Created using glass with a one-sided multi-layered low-emissivity coating applied by the magnetron method: hard (k-glass) and soft (i-glass).

This is hard coated float glass.

Sputtering on the surface of glass from metal oxides improves its energy-saving properties and reduces the emissivity. During production, hot float glass is pyrolyzed with a thin metal oxide film.

As a result of the interaction of glass atoms and metal oxide, a resistant coating is formed that protects against mechanical damage. To enhance the heat-shielding characteristics, K-glass is additionally tempered and laminated.

The use of K-glass contributes to the fact that the heat returns back into the room and does not go anywhere. This significantly reduces energy costs and saves the budget.


It has similar characteristics to K-glass, but has higher performance.

The float glass is coated with two layers of low-emissivity metal oxide sputtering.

This process takes place with the installation of magnetron sputtering in vacuum equipment. The metallized film is "magnetized" to the glass layer. This method of spraying is called "soft" or DoubleLow-E.

Since the coating of i-glass is "soft", its abrasion resistance is low compared to float glass and K-glass.

I-glass needs very careful transportation.

Sun protection double-glazed window

Protects the room from sunlight and excess heat. It consists of several glasses, between which there are special films or coatings that reflect or absorb the sun's rays and do not let heat into the room.
  • The glass coating is able to reflect the energy falling on them.
  • In the production of low-e glass, there are two types of coatings:
  • Metal oxide pyrolytic coatings are applied to clear and colored glass during production on a float line.
  • Metal or metal oxide magnetron coatings are deposited on glass with an electrochemical process in a high vacuum state in special facilities. They are less stable than pyrolytic ones, and therefore must be inside the double-glazed window; glasses of this type are produced in a wide range of colors.

This is a body-tinted glass with the addition of metal oxides. Depending on the color and thickness of such glass, its solar factor varies from 40% to 80%.

When solar radiation is absorbed, such glasses give off heat to the outside, some of it penetrates into the room.

This is an undesirable effect when the room needs to be cooled. In this, absorbing glasses are inferior in characteristics to reflective ones.

Absorbent glasses are produced in different colors: bronze, grey, green, blue and dark blue.

Architectural glass

One of the features of this glass is the perfect transparency in any shade. This allows you to create with it unique designs of building facades and interiors.

The second feature of architectural glass is its strength. It withstands heavy loads and does not break on impact. This makes it an ideal material for use in structures that are subjected to heavy loads, such as building facades.
