IG-units

Occupying around 80% of the general window space, glass pain significantly influences insulating qualities of the construction.

In order to provide our customers with the highest thermal insulation we offer single and double IG-units filled with inert gasses Argon and Krypton. Apart from comfort customers obtain possibility to significantly reduce heating and conditioning costs.

The standard glass pain offered by Korsa TM contains ClimaGuard Solar - insulating glass which meets highest requirements of thermal and sun insulation. With ClimaGuard Solar only 42 % of the direct sun rays enter the room. It results into significantly lower air-conditioning costs and favor comfort wellbeing. At the same time a low U-value (1,1 W/m2K) decreases heating costs during cold days of the year. Thus ClimaGuard Solar ensures year round climate control.

Glazing formula Glazing Gas Ug(W/m2K)
4-12-4-8Ar-4i Double Argon 1,4
4-16Kr-4i Single Krypton 1,3
4-16-4-16Ar-4i Double Argon 1,28
4-12-4-8Kr-4i Double Krypton 1,06
4-16-4-16Kr-4i Double Krypton 0,99
4-16-4-4Kr-4 Double Krypton 1,2

Toned effect of the IG-unit is reached with the help of special colored polymeric tape which is applied on the surface of the transparent glass. Main benefits of such approach are protection from intense sun rays, safety of people in case of glass breakdown and keeping personal privacy.

Tape name Color
1. R-20 Grey, reflecting
2. R-15GO Gold, reflecting
3. R15B Bronze, reflecting
4. NRM B PS2 Bronze, matted
5. R15GN Green, reflecting
6. R15BI Blue, reflecting

Ways to increase sound protection of the construction:

  • Enlarging of glass panes’ amount in the construction
  • Installation of triple glass
  • Filling of the IG-unit with inert gasses Krypton and Argon increases not only thermo-insulation qualities of the window but also significantly decreases level of sound pollution inside the room.
  • Increasing of the width between glass panes

Here you can see a table with the range of the glass distance and respective level of the sound protection we offer:

Warm Edge Spacer by Swisspacer TM

The main disadvantage of aluminum spacer bar is high level of thermo conductivity, which creates “cold zone” around the glass perimeter during cold seasons. Resulted from high thermal misbalance condensate or even icing may appear around the glass.

This problem can be solved by WARM EDGE spacer bar.

Thanks to unique qualities of “warm” spacer bar, the heat transfer coefficient of the whole window can be decreased by 12% comparing with the window, equipped with aluminum spacer bar. Plastic spacer bar increases temperature at the edge of the glass and assures energy savings at the level of 5% depending on the glass. Using “warm” spacer bar it is possible to save 5% of the heating costs during cold season.

What is WARM EDGE spacer bar?

Warm Edge spacer bar is a closed plastic frame which separates two glass panes in a double and triple glazing window. The spacer bar is fixed to the glass panes with two layers of sealant, creating vacuum between panes filled with air or gas. The spacer bar contains special desiccant in it which absorb moisture within the window cavity preventing condensation within the insulated glass panes.

Warm Edge spacer bar like SWISSPACER is made of an insulating plastic composite material that becomes a barrier to heat loss. Thanks to this bar warmth doesn’t escape from the house during cold seasons resulting into comfortable interior climate as well as reduced energy bills. The spacer works the same way in warm climates – low air permeability saves cooled fresh air inside the room. Thus you need less time for conditioning and ultimately get lower bills to pay.
