Structural Silicone Glazing
The use of high-performance silicone sealant as a structural bonding agent to secure glass panels to their supporting framework, transferring wind and dead loads through the adhesive bond.
Technical Details
Structural silicone glazing (SSG) uses specially formulated two-part silicone sealants that cure to form a permanent, flexible structural bond. The sealant must have documented tensile and shear strength properties and undergo compatibility testing with the specific glass and frame materials. ASTM C1184 governs structural silicone sealant requirements. Proper joint design, surface preparation, and cure conditions are critical to performance.
Frequently Asked Questions
How long does structural silicone last?
High-quality structural silicone sealants have a proven service life of 30+ years when properly specified and applied. They maintain flexibility and adhesion through thermal cycling, UV exposure, and weather.
