GEALAN-LINEAR - Optical perfection with optimum values


The GEALAN-LINEAR is a 74-80 mm system, balanced in every detail, for the highest demands on modern windows with respect to workability and storage.

The window manufacturer will appreciate the high stability, thanks to the optional bonding technology with the GEALAN innovation STV®. The system is also optimally prepared for machine bonding of glass.

The house builder or homeowner, will notice the design: The profile is based on a consistently linear design language, which is currently setting the tone in architecture. A range of glazing beads matching the design supports the concept. Narrow face widths in the frame and sash of the new system also provide more light in the building. This is important both for new buildings and for renovation projects.

On the thermal insulation side, the system achieves values on a competitive level; it will be available with GEALAN-IKD®. Within the GEALAN portfolio, it complements GEALAN S 8000 IQ and GEALAN S 9000 and is fully compatible with existing products.
