Casement Windows
for a perfect living environment
The S 8000 profile system demonstrates GEALAN's consistent focus on the needs of the market. The development objective for this system with rebate gaskets and an installation depth of 74 mm was to create a cost-effective profile with optimum use of materials, for easier and more efficient fabrication by window manufacturers.

Installation depth of 74 mm
The installation depth of 74 mm ensures excellent heat and sound insulation

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

Economical efficiency
Large main chamber for large steel stiffening elements, with only one stiffening steel required for frames, sashes and mullions

Optional passive ventilation
The patented ventilation system GECCO for a controlled exchange between inside and outside air provides improved room climate and greater living comfort.

Versatile surfaces
Available in a wide selection of GEALAN-acrylcolor® colours and (wood grain) decor foils
Statics: large-scale planning
Particular attention was paid to profile stability when developing the S 8000 system. The main chambers for the steel stiffening element were therefore made corresponding large.
The result is very high flexural rigidity of the standard stiffening elements, which in turn benefits the profile stability. This opens the door 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 window width and the resulting overall surface area.
- 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.

Colouring in the S 8000 system
GEALAN offers a wide range of options for bringing colour to PVC windows. One of them is the proven surface technology GEALAN-acrylcolor®. The coloured acrylic layer is scratch-resistant, weather resistant and easy-care. That means that window systems with GEALAN-acrylcolor® meet the highest technical and functional demands for innovative, coloured surfaces.There are also a wealth of options for creating coloured window and door profiles with GEALAN’s extensive range of decorative foils. The standard range offers a wide spectrum of colours. Additional tones and textures are available upon request on a property-related basis.
