High-performance mullion/transom façade with 50 mm face width – the basis for a variety of solutions
The Schüco FWS 50 façade system is an impressive basic system for façades and skylight areas with a high level of flexibility and attractive design options, including optimised fabrication and installation processes. Thanks to a broad system range, solutions for the most varied requirements and applications can be implemented.
A transparent system solution integrated in the profile for spandrel safety barriers blends seamlessly and elegantly into the external façade appearance. The required safety barrier loading for floor-to-ceiling opening units and low spandrel heights can be implemented with consistent profile face widths and a continuous profile.
The mullion/transom façade with 50 mm face widths offers a high degree of design freedom with a large selection of pressure plates and façade cover caps as well as the combination with Schüco window, door and sliding systems.
System-optimised components guarantee the simple and reliable integration of electrical components, e.g. for automated Schüco door or sun shading installations.
With the mullion/transom façade, Schüco is once again fulfilling its obligation to create ecologically sustainable products. The Schüco FWS 50.SI (Super Insulated) system option has been awarded the Silver “Cradle to Cradle Certified™” sustainability label by the independent C2CPII institute in cooperation with EPEA in Hamburg for its recycling properties and minimal toxin content.
Schüco FWS 50, thermally insulated self-supporting aluminium façade system
As a mullion/transom construction for multi-storey façades with an internal and external face width of 50 mm.
Design features:
The construction must be sealed from outside using aluminium pressure plates to suit the infill thicknesses.
Load-bearing structure:
The load-bearing structure of the façade construction consists of rectangular multi-chamber hollow profiles.
The load-bearing profiles are on the room side.
All profile edges are rounded.
The transom profiles are notched and overlap the mullions where they intersect, so that any moisture is reliably drained away.
On multi-storey façades, all horizontal joints must be constructed using the joint connectors and joint tolerance seals belonging to the system.
Appropriate system-based aluminium insert profiles and half profiles, as well as expansion joint seals, must be used for vertical expansion and assembly joints.
Glazing / insert units:
All glazing, even in the insert units, lies in the same plane. The glazing gaskets made from weather-resistant, black EPDM on the room side are of different depths in the mullions and transoms (6 mm offset).
Two individual gaskets made from weather-resistant, black EPDM, with a height of 5 mm, are positioned on the outside. Cruciform gaskets made from EPDM must be used where mullions and transoms join.
In principle two individual gaskets and butyl tape must be used on faceted areas and for roof glazing.
Ventilation:
Rebate base ventilation and vapour pressure equalisation take place at all four corners of each module field into the mullion rebate.
For field drainage and ventilation, appropriate openings must be made in the aluminium pressure plates, cover caps and gaskets.
Profile face widths:
Mullion, assembly mullion, transom 50 mm
Profile basic depths:
Mullions 50-250 mm
Transoms 55-255 mm
Cover cap (mullion) 20 mm
Cover cap (transom) 15 mm
The profile basic depths must be offered in accordance with the structural requirements and the plan specifications. However, note that a uniform mullion depth is required for all units. Furthermore, the transoms must have the same depth as the mullions.
