Spandrel Glass

Create custom accents in an array of different patterns and colors with Spandrel glass

Spandrel glass can be created in a couple different ways – one is by applying ceramic frit enamel to the glass with a Union Tool roller coater. Our coater can handle glass sized up to 84″ x 144″. The ceramic frit is then permanently fused onto the glass through a heat strengthening or tempering process.

Enamel or translucent ceramic frit can be applied as a solid backing or silk screened to achieve geometric shapes (such as lines or dots) for special shading applications. Our equipment is capable of handling custom silk-screening of up to 80″ x 144″ in size.

Ceramic Frit glass products are available in a multitude of standard colors as well as custom colors.

Spandrel glass can also be created by using an Opaci-Coat. Opaci-Coat-300 is a one component, water-based silicone coating that is fully cured to a tack-free silicone elastomeric film, providing opacification in any color to glass. Opaci-Coat 300 is available in standard colors of Black, Primary White, and Warm Gray, as well as many Custom Colors.
