Silicone Structural Glazing

Silicone Structural Glazing is the use of a silicone sealant for the structural transfer of loads from the glass to its perimeter support system and retention of the glass in the opening.

Glass is not typically used as a structural member. Support framing must be of sufficient strength and dexterity to absorb all loads resulting from wind, thermal expansion or building movement. Higher light-transmitting coating may show edge read-through. Insulating glass used in structural glazing must be silicone units. Opacified spandrel must have trim in the back of the opacifier to ensure glass-to-silicone adhesion. The compatibility and adhesive characteristics of the structural silicone are to be confirmed in the early stages of design.
