So just what is "thick glass", anyhow? Thick glass (meaning any custom glass over 1" in thickness) is most often used horizontally for countertops, bars, islands, tables, and so on, but sometimes in upright positions such as backsplashes, decorative walls or wall dividers, signage, and artworks. It is available in multiple textures, in either Aqua Clear, Ultra Clear, or our Colorfuse™ thick glass.
