Insulating glass units produced by using the heat reflecting glass units and therefore fulfilling the improved function of heat insulation
- Function: ordinary glazing + heat insulation
- Application area: In residential or public buildings where requirements for heat energy savings are raised
Heat reflecting glass units:
- 2-glass units with two glasses, which are made with 1 or 2 heat reflecting glasses. It is suitable in residential buildings, where are requirements for heat saving.
- 3-glass units with three glasses, which are made with 2 heat reflecting glasses. It is suitable in residential or public buildings, where are very high requirements for heat saving. 3-glass unit is suitable for Passive house. Passive house – it is heat reflecting house, were amount of used energy is about 80 percent lower compared with most of Europe buildings.
