Window types
The opening, hopper, opening-hopper, hopper-sliding and tilting windows are made of three air-chambered IMPERIAL system. The heat transmission coefficient of the profiles is UR=2,2 - 2,3 W/m2K, based on which they can be classified into 2.1 frame-group accordant to DIN 4108. The profile depth of the window frames is 65mm and of the windows is 74mm. The wall thickness of the profiles is 1.7 – 2.0mm. The glass thickness can change between 4 and 51mm. The windows can be completed with fix or blinded insect screens. LUXUS systems are recommended for exclusive demands, and STEEL LOOK system for steel structure imitation. VISION hidden leafed system is practical if we want uniform look on the whole glass structure, independently that it does or not contain doors or windows. The 75mm profile depth SUPERIAL system satisfies greater heat insulation demands. UR=2.0 W/m2K. The thermal bridge ECONOLINE profile family is suitable for indoor usage.
