VISS HI

VISS HI
Highly thermally insulated mullion and transom construction for single and multi-storey facades, optionally available in polygonal design with different angles

Insulating cores made of plastic foam are used in the glazing rebate to reduce thermal radiation. These insulating cores must allow ventilation of the edge seal.

Depending on the thickness of the filling, Uf values of 0.7 to 1.2 W/m²K, including the influence of the screw fixing, are achieved with these insulating cores.

Design features:
The supporting structure of the facade construction consists of rectangular or specially shaped
Hollow steel profiles with a face width of 50/60 mm and different construction depths. The
supporting profiles are arranged on the room side. The transoms are connected to the posts by
Welding or special T-connectors.
External cover profiles in aluminium/stainless steel, face width 50/60 mm, with different depths
and contours.
Glass / infill thicknesses up to 70 mm can be used. All glass panes – even those from
Insert elements – are arranged in the same plane.
The sealing to the glass panes and/or infill is done with EPDM seals. The
inner seals form the water-bearing level of the system. Compensation of different
Filling element thickness is achieved by variable system seals. The upper glass edge seal is achieved by
a cloth vulcanized to the horizontal seal is covered. Due to the overlapping of the
horizontal seal and the vertical seal, controlled drainage of the glazing rebate
achieved. The basic rebate ventilation as well as the vapour pressure equalisation of the glazing rebate to the outside is
invisibly field by field by means of corresponding expansion pieces in the bolt area below the
outer cover profile.
The pressure bars are fixed by means of stainless steel screws, centering discs and insulation clamping knobs.
connected to the supporting structure. The insulation clamping knobs are clamped in the supporting structure.
For the design as a high insulation façade, the space between the panes in the mullion and
Bolt a system-bound, innovatively developed insulation core according to manufacturer’s specifications
to use.
There must be no direct connections or thermal bridges through the screw connection between
Supporting structure and external pressure bars are created. All screws for outdoor use
shall be made of stainless steel.
