Simply more light
GEALAN-LUMAXX is an interesting combination of a traditional frame with a lowered sash, which in finished windows allows you to achieve the effect of extremely narrow window frames and consequently have up to 25% better light access. In GEALAN-LUMAXX, the low frame/sash combination has a height of 103 mm and is complemented by a design that includes a monostulp combination with a sash width of just 106 mm. Previous designs with movable mullions often took up as much as 170 mm of window width or more. These massive assemblies with a wide mullion interfered with the window’s silhouette and significantly reduced the flow of light into the room. With GEALAN-LUMAXX, the use of lowered profiles and the effect of a delicate, slender window has finally become possible without sacrificing comfortable operation and security.
Excellent thermal insulation
The excellent thermal insulation of the S 9000 system is not a coincidence, but the result of deliberate research and development work. The results speak for themselves. Numerous calculations have proven the achievement of excellent thermal insulation parameters. From the beginning, the project’s goal was to achieve Uf = 0.92 W/m²K using standard steel reinforcements and thus meet the passive standard. This was achieved thanks to the synergy of innovative details used in the design of this system.
