What is spandrel glass?

Spandrel glass is a type of opaque glass used in buildings, typically installed in the areas between the floors of a building where the structure is exposed. Spandrel glass is commonly used to conceal structural elements, such as columns, beams, and floor slabs, while also providing a uniform appearance to the building's facade.

Spandrel glass is manufactured by applying a ceramic frit to the surface of the glass and then firing it in a high-temperature kiln. This process creates a durable, opaque finish that can be customized in terms of color, opacity, and texture to match the overall design aesthetic of the building.

In addition to its aesthetic benefits, spandrel glass also has practical advantages. It can help to reduce glare and heat gain in a building's interior, providing both thermal and visual comfort for occupants. Spandrel glass is also easy to clean and maintain, making it a popular choice for commercial and residential buildings alike.
