Coated Glass
Spandrel Glass
Spandrel glass is opacified glass, typically produced by applying a ceramic frit coating, used to conceal structural elements such as floor slabs, columns, and mechanical systems behind a curtain wall while maintaining a consistent facade appearance.

Key Features
Conceals structural and mechanical elements behind a uniform facade appearance, available in custom colors to match or contrast with vision glass, and is typically tempered for thermal stress resistance behind an insulated cavity.
Where This Glass Is Used
Curtain wall systems, specifically at floor-line and structural transition zones where vision glass is not required.
Manufacturing Process
- Ceramic frit application — An opaque ceramic frit coating is silkscreen- or roller-applied to one glass surface and fused during tempering.
- Color matching — Frit color is formulated to match or intentionally contrast with adjacent vision glass for a coordinated facade appearance.
- Tempering — Spandrel lites are tempered to withstand the higher thermal stress caused by heat buildup behind the opaque coating.
- Insulation backing — An air space and insulation is typically installed behind the spandrel panel to manage heat buildup and improve thermal performance.
Applications & Use Cases
- Curtain Wall Floor-Line Panels — Standard application concealing floor slabs and structural transitions between vision glass bands.
- Mechanical Screening — Conceals rooftop or in-wall mechanical equipment behind a consistent facade line.
- Color-Matched Facade Design — Enables uniform facade appearance across vision and non-vision areas.

Technical Service
We support your project from drawing review to delivery, not just order fulfillment.
- Drawing & Spec Review — Shop drawings and project specs are reviewed before production to confirm sizes, tolerances, and edge/hole details match your requirements.
- Testing & Documentation — Mill test certificates, thickness/strength test reports, and compliance documentation provided for project submittals.
- Technical Consultation — Our team advises on coating, thickness, and configuration selection to meet your project's structural and energy code requirements.
Customization
- Custom Cut Sizes & Shapes — Curved, notched, cut-corner, and irregular shapes fabricated to your CAD drawings, not limited to standard rectangles.
- Edgework & Drilling — Polished, beveled, or seamed edges, plus precision hole drilling and cutouts for hardware and fittings.
- Coating & Printing Options — Combine with Low-E coating, tinting, or ceramic silkscreen/digital printing on the same order.
Packaging & Shipping
- Export-Grade Crating — Reinforced wooden A-frame or flat crates with edge protection, built for ocean freight handling.
- Container Loading — Load plans optimize container utilization while maintaining safe glass spacing to prevent transit damage.
- Shipping Documentation — Packing lists, certificates of origin, and mill certificates prepared in advance for smooth customs clearance.
