Suitable for triple functional glazing with a maximum thickness of 52 mm (STV® 54 mm).
Intelligent sealing concept with up to three end-to-end sealing levels.
Very good heat and sound insulation thanks to the six-chamber design and large installation depth for the frame and sash.
Optimised for the use of STV® for dry bonding the pane and sash upstand.
Narrow visible width and 15° incline as a design feature.
During development of GEALAN-LUMAXX®, the entire frame geometry was optimised while the profile widths were compressed to a minimum. The designers paid special attention to achieving a balanced relationship between insulating properties and statics, as well as a perfect interplay of components. The symmetrical effect of the narrow single mullion also adds to the flexibility of use in window construction.



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.

The coloured acrylic layer is twice as hard as the PVC surface of white windows. It is highly scratch-resistant and is largely resistant to the effects of weather. The semi-matt, smooth and non-porous acrylcolor surface is insensitive to accumulations of dust and dirt. There is no spalling or chipping and no need for laborious repainting. Acrylcolor windows require virtually no maintenance and are extremely easy to care for.

Rosenstrasse comes alive again. "You couldn't have described it any better," said Chaplain Daniel Schmid when he blessed the new premises of the Academy for Social Pedagogy and the new Vocational school for child care in Rosenstraße in Furth im Wald.
