Thermally insulated mullion/transom system made from steel for large-scale vertical façades
Using the VISS TV (Trockenverglasung = dry glazing) steel system based on a dry glazing method, architecturally impressive mullion/transom constructions can be created for large-scale vertical façades.
With narrow profile face widths and different basic depths, the room-side load-bearing structure of the façade units can be designed in a variety of ways and with good light penetration.
With aluminium cover cap profiles in a range of depths and contours, an architectural statement can also be made with respect to the outer covering of the load-bearing structure. Cover cap profiles in stainless quality complete the wide range of design options for the façade.
With slim face widths, the system ensures maximum light penetration. The intersections of the skylight construction and the vertical façade are achieved with visual elegance.

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 bullet-resistant requirements, the fabrication instructions 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 bullet-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.
