S 8000 IQ PLUS Window

S 8000 IQ Plus window

The new generation of window profiles S 8000 IQ Plus is the best choice for modern and elegant buildings. Attractive, rounded contours of the frame give these windows vibrant yet harmonic appearance. The S8000 IQ profile series are available in white or wood decor colours.


mproving the thermal insulation of a building is a core element of GEALAN's new six-chamber system with a construction width of 83mm: the S8000 IQ plus rebate seal system. It is designed especially for these constructions where the window frame needs to be over 80 mm wide. With a six chamber design and increased width, this system offers ideal protection from cold and noise, helps reduce heating costs and makes an active constribution to sinking CO2 emissions. Large steel stiffeners also add to structural rigidity. The system proves highly resistant against forced entry. The new frame system S 8000 IQ plus offers a wealth of combination possibilities thanks to full compatibility with all sashes of the standard S 8000 IQ system (classic with stepped sash, and design with semiflush sash). To prevent mould and improve the room climate, the patented GECCO (GEALAN CLIMA CONTROL) ventilation system can be installed.
