Structural Glazing

This technique can be used to create all-glass facade in which the actual structure is hidden behind the glass. Glazing in which the silicone seal is designed to transfer the stresses and to be resistant to UV radiation since there is no rebate on the edges. The structural glazing facade technique can be used with single panes of glass,coated or non-coated double glazing enamelled glass, etc.

Principle of a Structural Glazing Facade​

Glazing (single panes or insulating glazing) will generally be factory bonded on a metal frame. the glass and frame unit is then transported to the site and fixed to the load-bearing structure.

A.The edge of the exterior pane will always be treated ; the edge of the interior pane will generally be as cut ; this edge will only be treated upon request sizes.


Glass Components

We generally recommend using glasses at least 6 mm thick. The glasses used are either single or double glazing in which at least one edge remains visible and exposed to radiation. For this reason, the seal must be made of silicone.

Coated float glass single Glazing

Yes – See solar control glasses with pyrotic coating which can be used in single glazing units – Stopsol – Sunergy.

Insulating Glazing

The height of the silicone seal is higher than that of ordinary insulating glazing and will be calculated to resist depression to wind on the glass. For safety reasons, the interior glass must never be toughened. This is to avoid the second pane of glass disintegrating if the interior pane is breaks.Where necessary, the interior glass will be strengthened. When using coatings (Stopray, Top N+, Energy N), the coating must be edge stripped to a higher level than that of a traditional glazing since the silicone structural glazing seal is positioned higher than a normal seal. This will cause a larger dark edge to be visible from the outside. When dealing with “stepped”  glasses, the visible height must be edge stripped.

Spandrel / Enamelled Glass

Yes – Check with the silicone supplier that the structural seal adheres to the enamel.
