VISS TVS SG
Thermally insulated, self-supporting steel façade system “without external cover caps and glass pressure plates, option with gas-tight (EN 1279, Part 3) or airtight (EN 1279, Part 2) pane edge joint”
As a mullion/transom construction for multi-storey façades with an internal and external face width of 50 mm

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.
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 insert profiles and half profiles, as well as expansion joint seals, must be used for vertical expansion and assembly joints.
Up to 8-metre installation height, without mechanical fixing; > 8 metres, with additional mechanical fixing

Glazing / insert units:
In the production of double glazed units, a pane of heat soaked toughened safety glass is used on the outside.
The insulating glass is mechanically fixed to the structure of the façade using screw-in glazing clips which are inserted into the pane edge joint between the double glazing panes.
The maximum distances between supports of the clips are calculated in accordance with the tables and fabrication information provided by the system manufacturer.
Depending on the pane composition and when using reinforced glazing supports in conjunction with aluminium or steel insert profiles and heavy duty connecting spigots, glass loads of up to ____ kg can be transferred per pane field (see the fabrication documentation from the system manufacturer).
Storey-height glazing with safety requirements in accordance with TRAV must be secured individually with additional glazing clips.
The remaining 20 mm wide joint between the glass edges is closed with a PE filling tape and sealed with silicone sealant: DOW CORNING, DC 795/DC 797 – SIKA AG, Elastosil 600/605.

Ventilation:
The façades must be designed according to the principle of overall ventilation. From a unit height of 8 metres or 8 fields, the rebate base must be ventilated. For transom lengths > 1500 mm, there must be additional ventilation in the centre of the field.
