Thanks to the six-chamber profile construction and a depth of up to 190 mm, the HST S 9000 provides exceptional stability and excellent thermal insulation - the Uf value reaches around 1.3 W/(m²·K). The triple sealing system and the possibility of installing triple glazing up to 52 mm guarantee a high level of energy efficiency and sound insulation up to 45 dB.
The innovative STV® dry glass bonding technology further increases the rigidity of the sash, enabling the production of large and stable elements that move easily and quietly. Thanks to the modern profile geometry with 15° slopes and narrow visible widths, the system fits perfectly into the architectural trends of contemporary buildings.
GEALAN S 9000 HST is available in a variety of decors and colors, including the weather- and scratch-resistant GEALAN-acrylcolor® acrylic surfaces. The combination of functionality, aesthetics and energy efficiency makes this system the ideal solution for modern homes, panoramic glass walls and elegant terrace exits.
With classic glass, a symmetrical and balanced appearance is already achieved in the standard version thanks to a narrow wing with a width of only 100 mm, which allows greater penetration of light into the space and an elegant, minimalist appearance of the entire construction.
With this special variant, the standard sash in the fixed part is replaced with a narrower glazing profile. This reduces the front width in the fixed part by more than 50% with unchanged thermal insulation.
