Enhancements Spandrel Glass.
Viracon offers a factory-applied, fire-fused ceramic enamel for spandrel applications. Spandrel is the portion of the wall located between the vision area of windows which conceals structural columns, floors, and shear walls.

Design Considerations
Spandrel options for your project
Matching Spandrel and Vision Areas
Looking to harmonize the spandrel glass with vision areas of your building?
- Lower light transmitting and high-reflective glass types provide the least contrast between vision and spandrel areas
- For visual continuity, use the same Low-E coating and glass color for the vision and spandrel glass
Contrasting Spandrel and Vision Areas
Looking to contrast the spandrel glass with vision areas of your building?
- Higher light transmitting, low-reflective glass types provide the greatest contrast between vision and spandrel areas
- For a visual contrast, use a contrasting Low-E coating and glass color for the spandrel color
Matching Spandrel
Contrasting Spandrel
When viewing the glass from the outside, the dominant visual characteristic is the exterior reflection. On overcast days, a greater visual difference is created between vision and spandrel areas due to the transparency of the vision glass and the perception of depth created by interior lighting. On bright, sunny days, when the exterior light intensity is far greater than the interior lighting level, the contrast can be minimized.
For help determining the best spandrel color for your project, contact Viracon’s Architectural Glass Studio.
Moiré
Moiré is an optical phenomenon that typically appears as a wavy, rippled, or circular pattern. It is formed when two regularly spaced, non-aligned patterns overlap. When using spandrel glass, moiré can occur when a pattern’s shadow is cast against the spandrel glass. The moiré pattern is not a defect in the glass or spandrel process, but rather a pattern formed by the eye.

Application Recommendation
Viracon does not recommend spandrel glass be used in any application where it can be viewed with daylight or artificial light on the opposite side, such as interior partitions, mechanical rooms, screen walls or glazing in a parking garage. For additional information, please review Viracon’s Ceramic Enamel and Ink Visual Characteristics Tech Talk.
Installation Recommendations
- Spandrel glass should not be used in vision areas
- Install spandrel glass with a 1” minimum airspace gap between the spandrel glass and the insulation
- Spandrel glass should be glazed against a uniform opaque background
- The ceramic enamel should be on the inner most surface of the glass configuration
- The ceramic enamel should not be exposed to the outdoor environment
Performance Note
Winter and summer U-Values are the only performance values available for spandrel glazing. The U-Values for spandrel glazing are the same as the corresponding vision unit, and the spandrel color does not impact U-Value.
