A class of its own

The new development in the 74 mm segment meets the highest demands on a profile in terms of design, performance, economy and versatility. This is how GEALAN-LINEAR® sets new standards.


introduced on video

The 74-mm technology, a further development in the 70-mm segment, ensures high stability with modern functional glass and, thanks to the multi-chamber construction, provides more safety, sound insulation and thermal insulation. The versatility of the system is complemented by the straight-line design, thus following the minimalist trend of modern architecture.

Benefits of GEALAN-LINEAR®


Clean and simple design language, oriented towards architectural trends towards straight-lined, angular window designs.


Innovative system construction, consequently designed for market requirements

Thermal insulation

Top values in the 74 mm segment with Uf value of up to 1.0 W/(m²K)


Optimised profile constructions and innovative details with high compatibility of profiles and accessories


Full product range right from the start, for windows, doors and sliding solutions


Straightforward design language

The system is based on a consistently sleek design language that is currently setting the tone in architecture. A range of matching glazing beads continues the consequent design of the exterior appearance also on to the interior side of the windows. Slim face widths in the frame and sash provide more light in the buildings.

Tapping into the full potential

Whether in new construction or renovation, GEALAN-LINEAR® impresses with its broad versatility. It is a complete system platform that includes windows, front doors and sliding doors. It can be expanded with the GEALAN innovation of the STV® bonding technology.


Stylish and timeless

The clear, angled design of GEALAN-LINEAR® has a refreshingly timeless effect and is in keeping with the modern architectural language. Especially in new buildings, angular forms and clear lines determine the trend towards open and quietly designed facades.

Ideal for many building applications

The slim construction depth of 74 mm is suitable for a variety of construction projects as well as in the renovation sector. The universal sash rebate is integrated in all window sashes and allows for classic blocking, gluing with STV® or production-optimised wet bonding.
