Float Glass

There’s only one name you need to know: Guardian

Making float glass requires a specific knowledge of chemistry and physics, and continually improving the science and process of float glass manufacturing is a core competency at Guardian. Guardian glass is manufactured around the world using the latest glass-making technology to produce float glass for a variety of applications in a wide range of sizes and thicknesses.

Characteristics

  • High light transmission 
  • Optical clarity 
  • Can be further fabricated into reflective, low-E, laminated, security, insulating, heat-treated and ceramic decorated glass

Applications

Clear Glass: Ideal where high visibility and clarity are required. Thicknesses from 1.7 mm to 12 mm.

  • Windows 
  • Solariums 
  • Shelves 
  • Tabletops 
  • Skylights
  • Greenhouses 
  • Display cases 
  • Picture frame glass
  • Doors 
  • Mirrors
  • Handrails 
  • Appliances 
  • Atriums 
  • Safety glazing 
  • Furniture applications

Green: Suitable when high light transmission and reduced solar heat gain are required. Standard thicknesses from 2 mm through 8 mm (5/16"); other thicknesses may be available on request.

  • Windows 
  • Solariums 
  • Tabletops 
  • Skylights
  • Handrails 
  • Atriums 
  • Safety glazing 
  • Furniture applications

Bronze and Gray: Suitable when reduced light transmission and reduced solar heat gain are required and when color is desired to enhance aesthetics and increase design flexibility. Standard thicknesses of 3, 5, and 6 mm; other thicknesses may be available on request.

Specialty Tints

UltraWhite™: Standard clear glass is actually far from clear. To make UltraWhite, Guardian uses a raw material formula that increases light transmission and neutrality while reducing the greenish tint that is most apparent in clear glass when viewed from the edge. This green tint becomes more visible as standard glass gets thicker. The result is pure, sparkling, very clear glass. Available in thicknesses ranging from 3 mm to 12 mm and sizes up to 130” x 204”.

CrystalGray®:Guardian CrystalGray is an innovative float glass substrate with a very light gray tint, ideal for a wide range of architectural glass markets. In addition to an attractive neutral color, Guardian CrystalGray offers an improved light to solar gain ratio compared to standard blue and gray tinted float glass. The technology behind Guardian CrystalGray allows higher light transmission while reflecting infrared energy, thereby reducing the heat gain for many architectural applications. This float glass in combination with Guardian’s high-performance coatings can help buildings achieve LEED (Leadership in Energy and Environmental Design) certification.

TwilightGreen™:Guardian TwilightGreen is a dark-green tinted float glass offering better solar heat control properties than standard green float glass and has a richer green color. Commonly used in both automotive and architectural applications, TwilightGreen provides superior energy saving characteristics when combined with our high-performance coatings for commercial buildings. 

MidnightGray™: MidnightGray is a dark-gray float glass appropriate for applications requiring very low solar heat gain and also privacy. Excellent for both architectural and automotive applications.

Like standard float glass, all Guardian Specialty Tinted glass can be used monolithically, tempered, laminated and fabricated. They can also be used on the exterior or interior lite of a vision insulated glass unit or in spandrel glass applications. Available in various thicknesses.
