AW3S Structural Glazing Systems

450 1

AW3S Thermal break structural glazing The AW3 S system has been designed for the fabrication of curtain walls for various architectural solutions. The AW3 S version is characterized by the total absence of visible metallic elements. Only the modular glass panes, with a gap of 16mm, are visible from the outside.



Raw Materials:

  • Extruded sections in alloy primarily aluminum EN AW-6063 T5 Gaskets/static and dynamics in EPDM compound Bottom gaskets of the joints are made with an Elastomer that is compatible with the silicon sealer

Thermal Transmittance:

Class 2.1certification according to the DIN 4108 regulations from the Giordano Institute in Bellaria. The interruption of the thermal bridge of the cells is obtained through the positioning of polyamide thermal break rods that have been mechanically grafted at the extrusion of the aluminum.


The mullions are available with depth of 90 mm and allow the fabrication of semi unitized curtain walls by means of pre-made frames ( sub-frame + glass panes ) with thermal insulation. The glazed panes, both in the visible and blind areas of the parapet, are solidly attached to the load bearing frame which is entirely in aluminum. The thermal insulation of the blind areas can be increased by applying an additional insulated panel to the spandrel area.


The gap between the glazed panes without mechanical retain in view is 16 mm. The glass carrier frames allow the installation of DGU between 23 and 32.5 mm thick, or, single glass can be used for the spandrel area. In this version the structural glazing secures the fixture of the glass to the relative frame against positive and negative wind loads whereas the weight of the glass is supported by a specific accessory.

Open-able Elements:

The top hanging opening are manufactured in thermal break frames, with self balancing friction stays in stainless steel that can bear a max of 120 kg; the open able frames are not visibly identifiable in the facade.

Possible Manufacturing Solutions:

Vertical and rounded curtain walls with inserted open-able concealed top-hung (Projection).
