PRODUCT DESCRIPTION
Spandrel glass (non-vision glass) is employed to conceal building components and create a continuous glazed façade. Typically installed above or below vision glass on each storey, it provides an opaque surface that can be matched or contrasted with the vision glass to achieve the desired architectural effect.

BENEFITS & APPLICATIONS
Spandrel glass enables uninterrupted glass elevations and a consistent external appearance while hiding services, columns or insulation layers. It is suitable for commercial buildings, office towers and high‑rise façades where visual continuity and façade coherence are required.

APPEARANCE
Spandrel finishes can be harmonized with or contrasted to the vision glass. Options range from fully matching enamel colours to deliberately contrasting tones or textures to create rhythmic patterns across the façade. Color uniformity and edge appearance are key design considerations.

TECHNICAL INFORMATION
RANGE

• Monolithic glass — opaque enamel applied on one face; may include COOL-LITE® ST or ST BRIGHT SILVER coatings on the external face (#2) where specified
• Insulated glazing unit (IGU) — combination with Saint-Gobain Glass solar control coatings on #2 and enamel on the exterior lite (#4) for improved thermal performance
• Shadow-Box — ventilated cavity configuration with a composition comparable to IGU, used when a ventilated assembly is required

PROCESSING
Enamels are formulated for printing on soda-lime float glass. During tempering the enamel fuses to the glass surface, creating a durable ceramic layer. Enamelling can also be applied to coated glass substrates where specification requires it, allowing integration with solar control products such as COOL-LITE® families.

PERFORMANCE
Performance data (thermal, solar and optical characteristics) vary by configuration and coating. Selection should consider thermal insulation, solar control, maintenance and regulatory requirements. Comparative tables are available for COOL-LITE® product options when specifying spandrel assemblies.

SPECIFICATIONS

• Main use: non-vision façade element to conceal building components, typically positioned above or below vision glass
• Main component: opaque enamelled glass with uniform enamel on one face
• Available configurations: monolithic; insulated glazing unit (IGU); Shadow-Box (ventilated cavity)
• Coatings (examples): COOL-LITE® ST, ST BRIGHT SILVER; Saint-Gobain Glass solar control coatings on selected faces
• Processing: enamels fuse during tempering to form a permanent ceramic layer; enamelling can be applied to coated glass
• Aesthetic options: matching, harmonized or contrasting finishes to coordinate with vision glass
• Design trade-offs: cost, flexibility, aesthetic outcome, maintenance and thermal performance
