Specialty GlassSystems
When it comes to turning bold ideas into reality, few offerings demonstrate our capabilities like our Specialty Glass Systems. These are the projects where engineering precision and architectural ambition demand more from everyone involved—and where GSI truly excels.
Specialized facades demand highly
engineered solutions—
which is exactly where we excel.
Over decades of experience, GSI has built deep expertise in highly customized assemblies across a broad spectrum of specialty systems. It’s where our passion for solving complex engineering challenges truly shines.

Six Technologies,
Infinite Possibilities
We offer six advanced glass technologies to meet performance, safety, and design requirements—each one a precision tool in service of your architectural vision.
Security (Laminated) Glass
Vinyl interlayer keeps shattered glass structurally intact. Used in storefronts, skylights, and partitions where safety continuity is non-negotiable.
- Fragments held in place after impact
- Reduces injury risk in high-traffic areas
- Applicable across storefronts, skylights, and partitions
Fire Resistant Glass
Rated to limit flame, smoke, and heat transmission through the glass assembly. Required by code in stairwells, exit corridors, and fire-rated wall assemblies where vision panels are needed.
- Available in 20-, 45-, 60-, and 90-minute ratings
- Maintains visibility while meeting IBC and NFPA requirements
- Compatible with curtainwall, storefront, and framed assemblies
Ballistic & Blast-Resistant
Two distinct but critical performance profiles. GSI specifies and installs the right system for the threat environment—from government facilities to high-security commercial buildings.
- Ballistic glass stops projectiles and controls splintering
- Blast-resistant glass acts as a barrier during explosive events
- Meets high-security commercial and government requirements
Electrochromic Glass
Tint-on-demand glass controlled by electric current. Manages light, heat, and privacy dynamically—without blinds, shades, or ongoing maintenance.
- On-demand privacy at the touch of a button
- Reduces solar heat gain and cooling loads
- Eliminates blinds and associated upkeep
Etched Glass
Precision surface treatment with nearly unlimited design options. More refined than sandblasting—resists fingerprints and staining while holding its finish permanently.
- Custom patterns and designs available
- Less porous than sandblasted—resists stains
- Maintains a clean, consistent appearance over time
Spandrel (Ceramic-Fritted) Glass
Custom enamel patterns baked permanently into the glass surface. The finish cannot be scratched or removed—consistent for the life of the building.
- Permanent enamel finish, cannot be scratched or removed
- Long-lasting color and pattern consistency
- Ideal for concealing structural elements within facade systems
Engineering &
Collaboration
Delivering specialty glass systems requires more than technical precision—it requires a deep collaborative process that begins at design and runs through final installation. By working closely with component suppliers and project teams, we ensure nothing is left to chance.
From initial design through final delivery, we stay engaged at every stage to catch issues early and keep the project on track.
Every component is tracked against specification. We hold our suppliers to the same standard we hold ourselves—no exceptions.
The design intent that started the project is the same one that finishes it. We protect the vision from first sketch to final pane.
Not every project fits
a standard category.
And that’s exactly where we thrive. GSI embraces the projects others won’t touch—where conventional system limitations are the starting point, not the finish line. We engage early, engineer carefully, and deliver systems that exist nowhere in a manufacturer’s catalog.
