Façade System AOC 75 ST.SI

Highly thermally insulated add-on construction for wide steel substructures, especially in the roof area

The Schüco AOC 75 ST.SI (Steel Super Insulation) façade system, with its 75 mm system width, is especially suited for wide steel substructures in the roof area and also fulfils the highest requirements in thermal insulation.

The basis for this is two pioneering system components: a specially designed gasket range for large ventilation cross sections as well as a passive house level isolator system that guarantees optimum security with an additional butyl seal, for applications in vertical façades and the roof area.


Fabrication benefits

  • Sealing components without use of sealant in the vertical façade for efficient and secure installation
  • Use of building authority-approved, powder-actuated fastener technology on steel substructures: minimised fabrication times compared to welding
  • Patented screw guide: different infill thicknesses can be inserted reliably and efficiently
  • Roof area with butyl tape sealing and integrated screw guide for maximum installation reliability
