Commercial Glazing Material Spec
Structural silicone glazing explained — when commercial spec requires SSG
Structural silicone glazing (SSG) bonds glass to aluminum mullion using structural-grade silicone sealant — the silicone is the structural fastener, not a captured glazing channel. Creates frameless aesthetic. Common on premium commercial curtain wall, automotive showrooms, hospitality, and luxury retail.
When does the architect spec SSG?
When the aesthetic requirement is frameless or flush glazing — luxury showroom, hospitality lobby, premium office. SSG eliminates the captured-glazing channel that visually breaks the glass field.
What sealants qualify for structural silicone glazing?
Dow Corning 995 Silicone Structural Sealant and Sika SikaSil WS-305 are the two dominant tier-one structural silicones in commercial Florida. Both carry 10-20 year warranty when applied per spec by an approved applicator.
Is ACG an approved structural silicone applicator?
Yes. ACG is an approved applicator for Dow Corning and Sika commercial sealant lines. Applicator certification on file for project documentation.
