Schüco USC 65, thermally insulated, self-supporting, unitised aluminium façade system
As a unitised façade for multi-storey façades with external glass retention frame or alternatively with SG bonding on 2 sides and retention frame on 2 sides for horizontal or vertical emphasis of the façade, load-bearing structure on the room side with 65 mm face width (unit joints and glazing bars).

Design features (façade load-bearing structure):
The load-bearing structure of the façade construction consists of right-angled, multi-chamber hollow profiles in unitised construction, using corner cleats with Schüco adhesive injection and bonding technology, mitre-cut, optionally with sash bars, inserted using T-cleats and seals with integral sealing channels for sealing the H-joints. The load-bearing profiles with a basic depth of 125 mm or 150 mm are arranged on the room side and have a continuous inside and outside face width of up to 65 mm. All profile edges are rounded.
Max. dimensions 2700 x 3600 mm, unit weight up to 500 kg.

Coupling of units:
The horizontal units are coupled using EPDM coupling gaskets, which must be inserted in the gasket locating grooves of the frame profiles. The vertical units are coupled using fixing lugs, which are part of the unit hanging brackets, and using horizontal gaskets. The coupling joints for the gaskets must overlap; the vertical coupling gaskets overlap the horizontal gaskets (saddle gasket and horizontal coupling gasket). During installation of units, a continuous saddle gasket must be located outside, horizontally at the bottom, and sealed. Units are fitted with an EPDM front chamber gasket to take up tolerances around 3 sides on the outside, fabricated as a 3-sided gasket frame or used off the roll by the metre with gasket corners. This gasket must be inserted in the outer profile of the continuous frame profile. The external glazing bead is fixed in place by means of a screw or, alternatively, by means of a PE cord in sections. The inner frame profiles and the all-round outer glazing beads receive a colour coating as described in more detail in the section on surface finishes.
The horizontal butt joint (= vertical size between two façade units one above the other) can take up tolerances, e.g. as a result of ceiling movements, of ± 5 mm or alternatively up to ± 7.5 mm (2 options for respective gaskets).

Design features (fixed glazing, frame solution):
Single or double glazing, glass thickness 22 to 56 mm with Thiokol edge seal can be used. The insulating glass is fixed mechanically using continuous, mitre-cut glazing beads.  
The glazing beads can therefore be designed as a flat glazing bead, U-shaped glazing bead or L-shaped glazing bead. The panes of insulating glass are fixed and sealed using EPDM glazing rebate gaskets on the room-side to the outside. All glazing, even in the insert units, lies in the same plane. 

Design features (fixed glazing for vertical emphasis of façade):
Stepped insulating glass (steps on 2 sides) between 32 to 56 mm thick with a silicon edge seal can be used. The units must be glazed by the customer.
The insulating glass is fixed mechanically to the frame profile vertically on two sides using glazing beads and horizontally on two sides using the bonding of the stepped insulating glass.  
The glazing beads can therefore be designed as a flat glazing bead / U-shaped glazing bead / glazing bead with tapering face width / L-shaped glazing bead. All glazing, even in the insert units, lies in the same plane.

Design features (fixed glazing for horizontal emphasis of façade):
Stepped insulating glass (steps on 2 sides) between 32 to 56 mm thick with a silicon edge seal can be used. The units must be glazed in the factory. The double glazing is mechanically fixed on the two horizontal sides using glazing beads and on the two vertical sides by bonding the stepped unit to the frame profile. The glazing beads can therefore be designed as a flat glazing bead / U-shaped glazing bead / L-shaped glazing bead. To cover the horizontal butt joint, a flat cover cap can be used horizontally, which covers the glazing beads and the butt joint between two units one above the other. All glazing, even in the insert units, lies in the same plane.
