The curtain wall consists of vertical mullions and horizontal transoms joined together with stainless steel pin joints. In case of straight wall elements, this offers the advantage of rapid construction of the front wall. It is possible to build up slightly facet-shaped curtain walls with screw joints for the transoms. The clamping strip is coupled to the mullions by means of an extruded connecting bar, which also forms the thermal break for the curtain wall. This clamping strip is formed with co-extrusion of hard plastic as a basis and soft plastic to guarantee sealing. The whole construction can be finished on the outside with several decorative beads. Besides traditional front walls with horizontally and vertically protruding lines, this series can also be used to construct a semi-structural front wall, whereby the outside of the front wall will only show vertically protruding cover caps.
