State-of-the-art system for windows, doors, and lift-slide doors, with a choice of two or three sealing levels
It offers the option of building passive house-compatible window elements, including in colour, in accordance with the ift directive WA-15/2 using standard profiles and standard 2 mm steel stiffening elements. The certified Uf value of 0.89 W/(m²K) confirms the outstanding basic heat insulation properties.
Despite the focus on narrow sightlines, the new sash/mullion profile doesn’t compromise when it comes to statics. Both use a particular steel which, due to its static properties, allows for elements of up to 2.30 m in white and 2.20 m in colour. In combination with STV® bonding technology, element sizes up to 2.50 m in white and 2.40 m in colour are possible.
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.
