Term of the Day: Spandrel Glass

Spandrel Glass is a type of glass used in building facades, particularly in curtain wall systems, to conceal structural elements, insulation, or mechanical equipment between floors. Unlike vision glass, which is transparent and allows light and views to pass through, spandrel glass is typically opaque. It can be produced by applying a ceramic frit, coating, or paint to the back of the glass, making it non-transparent. Spandrel glass is often used for aesthetic purposes to create a uniform appearance across the building’s exterior, providing continuity between vision glass panels.
