Optimised heat insulation
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.
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.





GEALAN-LINEAR®
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.
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.
