Glazing is a construction consisting of one or more glasses where there is air space between them, formed by different sizes of spacers and hermetically closed.
A glazing must have two degrees of compaction in order to have better technical parameters. Double glazing consists of a spacer frame, filled with adsorbent (molecular sieve), on which butyl is laid both sides, used as a barrier against water vapor passing (first degree of compaction). The second barrier is the outer sealing of the space between the glasses and the spacer with polysulfide.
Spacer, which is mostly made of aluminum, is used to divide a certain space of the glass, and the moisture together with the air, sealed inside in the process of manufacturing is absorbed by the absorbent it is filled with. If glazing is properly implemented, no water could penetrate outside as well as no condensation occurs between the glasses. The glazing constitutes around 80 % of the whole window and thus it mostly affects its insulation characteristics thermal insulation U (W/m2K), sound insulation R (dB), unscreen or solar factor g (%), light transmittance (%)

Characteristics of the glass unit:
1. Heat transfer coefficient (Ug) is the amount of heat in watts, which is transferred per unit through 1sq. m of glass per degree Kelvin difference from internal and external temperature (Ug=W/m2K). This is the most important feature of a glazing. Small value of Ug coefficient means less loss of heat and less expenses of heating during the winter.
2. Noise insulation (Rw) Rw Index measures noise insulation of the glass unit. The higher the value of the index is, the better the noise insulation. l UV (%) – harmful ultra-violet rays passing through, leading to fading of colors and causing skin cancer
3. Solar factor (%) sum of all direct passed energy and part of it that was absorbed from glass which is emitting from window to the inner space, I. e., the whole quantity of energy that passes through glass unit. The more the direct reflectance of solar energy from the glass is, the lower the solar factor is and less the expenses for air-conditioning in summer months are.
4. Light-transmission (%) visible light that passing through glass. The less the value in %, the darker is the premise
5. Reflection (%) the amount of the reflected light by glass package. The bigger the % of the reflection of the glass, the greater is its reflexivity
Low-e glass
- Improves solar and thermal control
- Reduces UV transmission
- Relatively inexpensive
- Reduce solar heat gain in winter
Toned Glass
- Reduces heat and glare
- Reduces cooling costs
- improves privacy
- Decreases visibility and light
Laminated Glass
- Harder to break
- Reduces noise
- Cuts down UV transmission
- Exposure to water can cause deterioration
Window Film
- Film is an effective and affordable way to keep heat out and also helps to reinforce your windows for safety.
