Installation depth 74 mm

Installation depth of 74 mm provides excellent insulation and soundproofing.

Efficient use of materials

Efficient use of materials in profilometry saves resources and thus helps the environment


Large main chamber for large steel stiffeners, with only one steel stiffener needed for frames, struts and posts.

Passive ventilation as an option

GECCO's patented ventilation system uses controlled indoor/outdoor air exchange, ensuring a better indoor climate and increased living comfort.

Versatile surfaces

Available in a wide range of GEALAN-acrylcolor® colours and with (woodgrain) decorative foils.

In the development of the S 8000 system, particular attention was paid to profile stability. Therefore, the main steel stiffener chambers were made larger.

The result is a very high compressive stiffness of the standard stiffeners, which in turn contributes to profile stability. This opens up possibilities for the construction of large elements and also allows window manufacturers to meet specific demands for large windows.

  • The maximum height of the window elements is determined by the width of the window and the resulting total surface area.
  • If the windows are large, the window elements will be subject to high forces.
  • Stable steel rigid elements ensure high flexural strength and allow large windows to be built.
