The VISS® TV tubular steel profile system is suitable for building large, highly insulated vertical façades where architectural style is not to be compromised.

With narrow profile face widths of 50 and 60mm and different basic depths, the inner loadbearing construction of the façade units can be designed in a variety of different ways and with good light penetration.

With aluminium profiles in a range of depths and contours, an architectural statement can also be made with respect to the outer cover caps of the loadbearing construction. Cover cap profiles in blue bronze and INOX quality complete the wide range of design options for the façade.


Fabrication benefits

  • Narrow face widths of 50 and 60 mm

Thermally insulated mullion/transom construction for single and multi-storey façades

Design features:
The load-bearing structure of the façade construction consists of right-angled or specially shaped steel hollow profiles with a face width of 50/60 mm and different basic depths. The load-bearing profiles are on the room side. The transoms are welded to the mullions or are attached to them using special connecting spigots.
In the case of façade units with burglar-resistant requirements, the fabrication and assembly guidelines from the system provider must be observed.
External cover cap profiles in aluminium / stainless steel, face width 50/60 mm, with various depths and contours.
Glazing/panel thicknesses up to 70 mm may be used. All glazing, even in the insert units, lies in the same plane.
Insert units from the JANISOL / JANISOL primo systems can be installed in the burglar-resistant façade as door and window units with building attachments that conform to the test certificate.
All glazing and/or panels are sealed in using EPDM weatherstrips. The inner weatherstrips form the drainage level of the system. The top pane edge seal is covered by a tab, which is vulcanised to the horizontal weatherstrip. The rebate base is ventilated and the vapour pressure of the glazing rebate is equalised to the outside in a concealed manner, field by field, by means of deflector blocks in the transom area below the outer cover profile.
The pressure plates are connected to the load-bearing structure using stainless steel screws, centring washers and insulated fixing studs. The insulated fixing studs are clamped in the load-bearing structure.
There must not be any direct connections or thermal bridging caused by the screw connection between the load-bearing structure and the outer pressure plates. All screws for external use must be stainless steel.
