Glass Size UltraGlas fabricates to virtually any size, including ovals, radii and custom shapes, up to 6’-6” x 10’-6” in size (some exceptions exist). Glass Thickness UltraGlas is available in all standard glass thicknesses — including 1/8”, 3/16”, 1/4”, 3/8”, 1/2” and 3/4”, as well as metric sizes. Not all “through-body” glass colors are available in all glass thicknesses — see Glass Tints (Colors).
