THE PERFECT MIX
The innovative S 9000 combined system

BENEFITS OF S 9000
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. The benefits in brief:

Suitable for triple functional glazing with a maximum thickness of 52 mm (STV® 54 mm). Narrow visible width and 15° incline as a design feature. Intelligent sealing concept with up to three end-to-end sealing levels. Optimised for the use of STV® for dry bonding the pane and sash upstand. Very good heat and sound insulation thanks to the six-chamber design and large installation depth for the frame and sash.

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.

Deep edge cover thanks to an upstand height of 26 mm for enhanced heat insulation. Perfectly fitting steel forms for the perfect balance between statics and heat insulation. Six chambers end to end in the frame, sash and mullion for outstanding heat and sound insulation
