Float glass

Start with a strong foundation

Great glass design begins with high quality float glass. Guardian Glass is rooted in the science of float glass manufacturing, which we began doing in 1970. We apply our deep knowledge and understanding of chemistry, physics and advanced technologies to create glass to meet and exceed your project’s requirements.


Float glass is a clear, distortion-free glass that we offer in a wide range of sizes and thicknesses to suit any flat glass application. Our float glass is prized for its high light transmission, optical clarity and ability to be fabricated to meet custom performance and aesthetics. It can be tempered, laminated, painted, silvered to produce mirrors or coated to provide better performance.

Guardian Glass uses the latest glass-making technology, heating mountains of silica sand and other raw materials to a liquid state and floating this on a bath of molten tin to produce a perfect ribbon of glass.

Clear annealed float glass is a clear, distortion-free glass that can be produced in a wide range of sizes and thicknesses to suit any glass application. The glass can be cut, machined, drilled, edged and polished. Annealing of float glass is the process of controlled cooling to prevent residual stress in the glass and is an inherent part of the float glass manufacturing process.

Clear & standard float

Clear float glass is the building block for all types of architectural and interior applications. When your float glass is prized for its high light transmission and optical clarity, and you operate float glass plants across the world, it’s no surprise that Guardian’s work on float glass never stops.


Improved solar control and aesthetic appeal


Improved solar control and aesthetic appeal

As a manufacturer of quality float glass since 1970, Guardian Industries delivers the glass products, global reach and expertise that you can rely on.

ExtraClear® and Guardian UltraClear® low iron glass

ExtraClear float glass offers exceptional clarity with a low iron-oxide content. The low iron content reduces the green tint of the float glass, allowing truer colors to be seen on either side. As a result, it offers the ideal design solution wherever a superior finish is required in both interior and exterior applications.

Specialty tinted glass

Guardian offers several specialty commercial float glass options to expand your design possibilities, each with unique benefits.
