Spandrel Glass
Heat-strengthened float glass with a colored-ceramic coating adhered to the back by a heat-fusing process. It has double the strength of annealed glass of the same size and thickness, enabling it to withstand greater uniform loads and thermal stresses. Spandrel glass cannot be re-cut after heat-strengthening. It is used as a fixed opaque colored glass on buildings in front of floor slabs and columns. It is available in a wide array of colors.
