The S 9000 is a versatile, state-of-the-art system for windows, doors, and lift-slide doors, with a choice of two or three sealing levels.
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.
