Passive house-certified mullion/transom façade for a variety of solutions with a steel appearance
Based on pioneering isolator technology, the Schüco FWS 50 S.SI (Steel Super Insulated) façade system offers solutions with extremely high thermal insulation for designing façades and skylights with a steel appearance, with values up to passive house level.
Thanks to a broad system range and optimised fabrication and installation processes, constructions for the most varied requirements and applications can be efficiently implemented in a variety of ways.
A transparent spandrel safety barrier integrated in the profile blends seamlessly and elegantly into the external steel 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.
Load-bearing I-shaped and T-shaped load-bearing profiles as well as steel U-shaped pressure plates with visible screw fixing allow slimline mullion/transom constructions to be designed with an elegant, high-tech appearance.
System-optimised components guarantee the simple and reliable integration of electrical components, e.g. for automated Schüco door or sun shading installations.
Schüco FWS 50 S.SI, highly thermally insulated self-supporting aluminium façade system
with I / T-shaped profile geometry
As a mullion/transom construction for a multi-storey façade
Design features:
Façade construction with an aluminium pressure plate and foam strip with an inwardly highly reflective aluminium foil to prevent thermal radiation.
Load-bearing structure:
The load-bearing structure of the façade construction consists of rectangular multi-chamber hollow profiles.
The load-bearing profiles are located 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, double T-shaped contour 50/15 mm
Transom 50/15 mm
Profile basic depths:
I-shaped mullions 125-175 mm
T-shaped mullions 125-250 mm
Transoms 21-130 mm
Cover cap (mullion) U-shaped 30 mm
Cover cap (transom) rectangular 8.5 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.
