Showcase your design fully

Let large expanses of glass shine without the interruption of unsightly construction materials. Guardian spandrel glass is an opaque panel located between areas of vision glass. Spandrel conceals building components like columns, floor slabs, HVAC systems, wiring or plumbing. Whether it's used in monolithic applications or in insulating glass units, Guardian Deco HT back-painted glass can add uniform color and a visually-pleasing complement to vision glass.

How it's made

Guardian Deco HT back-painted glass provides uniform color on back-painted glass. A cutting-edge proprietary coating brings superior durability to conventional frits prior to heat treating. After heat treating, the coating bonds to the glass for a smooth look and long-lasting beauty in your architectural projects.
