S 9000 profile system

The innovative state-of-art system 

Developing a system with the best heat insulation properties does not happen by accident, but rather as a result of focused development work.

Our success proves us right. Numerous calculations have produced outstanding heat insulation values.

Right from the beginning, the goal of development was to achieve a heat insulation value of Uf – 0.92 W/m²K for the standard combination with steel, making the system suitable for use in passive houses.

This was accomplished through the sum of the innovative system design details.


S 9000 is the new GEALAN central gasket system with a stable bar in the window frame. The central gasket bar effectively protects the mechanical parts in the window from external factors. Central gasket systems stand out for their excellent insulation qualities.

Its outstanding static properties make S 9000 plus ideally suited for building large elements with acrylcolor surface finishing. GEALAN’s STV bonding technology means that S 9000 plus windows can be further upgraded for stability and safety of use.

  • An installation depth of 82,5 mm ensures excellent heat and sound insulation

  • Large main chamber for large steel stiffening elements

  • Efficient use of material in the profile geometry saves resources and thus helps the environment

  • Only one stiffening steel necessary for frames, sashes and mullions

  • Option of improved room climate and greater living comfort with the patented ventilation system GECCO for a controlled exchange between inside and outside air

  • Available in a wide selection of acrylcolor colours and (wood grain) decor foils

  • When windows are large, the window elements are subject to high forces

  • Stable steel stiffening elements ensure high flexural rigidity and allow the construction of large windows

  •  The maximum height of the window elements is determined by the window width and the resulting overall surface area
