Structural Glazing System Types
4-Sided Structural Glazing
4-sided structural glazing is the most common and usually most cost efficient type of structural glazing system used in European countries. Glass is supported on all four edges of the glass with structural silicone. 4-sided SG systems are typically fabricated in a production facility and erected at a jobsite.
2-Sided Structural Glazing
2-sided structural glazing systems use structural silicone on two of the four sides of the glass. The other two sides of the glass are either mechanically supported or are not structurally supported by a frame. 2-Sided SG systems are fabricated in a production facility or at the jobsite.
Slope Glazing
Slope glazing is when structural glazing is applied on a façade that is not vertical. Typical slope glazed SG systems are skylights. In such cases, the weight of the glass is considered in the SG joint dimensioning calculations.
Stepped Glass
Many SG systems install the SG joint on the internal surface of the outboard pane. In these systems, the insulating glass units are produced in a step fashion which allows glazing to the outboard pane. More traditional SG systems install the structural joint to the internal surface of the inboard pane of the insulating glass unit.
U-Profile Channel Systems
There are many proprietary systems that allow insulating glass units to be attached mechanically to the structure by a U-profile in the cavity between the two panes of glass. Depending on the nature of the system, the silicone sealant may or may not be performing as a structural glazing sealant in the design.
Total Vision Systems
Total vision systems, which are commonly used at the front of a building to maximize vision area, use a glass fin to structurally support the vision glass. In such cases, the 2-sided SG system may use the structural silicone in shear from the glass edge to the glass fin.
