Modular mullion/transom façade system made from steel with a wide range of design options

Be it a newbuild, conversion or renovation, the modular VISS steel system for thermally insulated mullion/transom constructions stands out as the optimum components from a technical and economical perspective can be selected for each project from the modular system, irrespective of the size.

With narrow profile face widths and different basic depths, the room-side load-bearing structure of the façade units can be designed in a variety of ways and with good light penetration.

Optimised insulation and structure combined with slimline window appearance

The perfect combination of design and material with high standards of thermal insulation and burglar resistance: Thanks to its new developed composite system, the pioneering high-end Janisol HI window system offers the best structural properties combined with outstanding U values.

As a further benefit, the basic depth of 80 mm guarantees the easy application of double and triple insulating glass.
