Guardian is one of the world's largest manufacturers of float glass and fabricated glass products. You also should know that we manufacture and supply the automotive industry with a variety of exterior products. We've also become a significant player in the building materials distribution business. And somewhere along the line, we became the world's largest producer of mirrors.


Low-iron glass – Clarity you can see.  Are you in the market for a crisp, clear glass without the long lead times? Do your customers want color neutrality and improved clarity on demand? Guardian Industries, a global leader in the glass, automotive and building products industries, may have the solution: UltraWhite™ low-iron glass.  UltraWhite™ has been selected as the glass of choice for the World Trade Center #7 Building project, shown at right.

Compare Guardian’s new UltraWhite™ glass to ordinary float glass, it becomes clear – clarity you can see.  Designers have long sought glass that doesn't dull or distort the true color spectrum. Guardian UltraWhite™ is that glass. The virtual absence of color makes UltraWhite™ glass the natural choice when true color and clarity count.


UltraWhite™ glass is manufactured with reduced iron content – low-iron glass is clearer. Our scientists have found that reducing the iron and using a new raw materials formula increases light transmission and reduces the greenish tint in clear glass that is most apparent when viewed from the edge. This green tint becomes more visible as regular float glass gets thicker. The result is pure, sparkling, very clear glass.


The stunning clarity of UltraWhite™ glass makes it an obvious choice for atriums, skylights, doors and entranceways, display cases and storefronts. As a matter of fact, UltraWhite™ can be used virtually anywhere regular float glass can be used.

UltraWhite™ provides a dramatic improvement when used in laminated applications. Until now, the typical result when laminating conventional clear float glass was color distortion and a reduction of visible light transmission as the laminate thickness increased. UltraWhite™’s combination of strength, security and distortion-free vision equals unparalleled performance.


UltraWhite low-iron glass is available in thicknesses ranging from 3 mm to 15 mm and sizes up to 130” x 204”. Guardian has implemented a regular production schedule to manufacture fresh UltraWhite glass to meet any construction schedule – 1st, 2nd, 3rd or 4th quarter.

Guardian ExtraClear™

The New Standard for Low-iron Glass.  Whether you are framing priceless art, a family photo or painting decorative glass, you expect the image to be clear and the colors to be true. Now you can count on it.

Guardian understands the importance of clarity. That’s why we created ExtraClear™. Guardian’s ExtraClear low-iron float glass utilizes a new material formula that increases light transmission and color neutrality when compared to standard float glass.  The result is clearer, true colors from your pictures, art and literally anything protected by glass.


ExtraClear float glass is a significant step above standard float glass. Containing a lower iron content, ExtraClear has a higher visible light transmission and offers superior optics and clarity compared to standard glass.

Standard clear glass has a greenish tint that is most apparent when viewed from the edge. This green tint becomes more visible as standard float glass gets thicker. We have reduced the greenish tint to allow a cleaner, brighter color spectrum through the glass.


ExtraClear float glass can be used anywhere standard float glass can. It does the job of standard float glass, only better and should be considered for many applications.

DiamondGuard™ LMG Glass

Low Maintenance and scratch resistance -- the future has truly arrived.  Any window that requires less cleaning is a blessing. But make that same window scratch resistant and color neutral and you have DiamondGuard LMG. It’s the latest advancement from the scientists at Guardian—a solution that will help you answer that consumer demand for “easy to clean” windows.  The key is surface properties that minimize debris accumulation and shed water to keep the glass surface cleaner and clearer. And since the coating is remarkably scratch resistant, no special handling during fabrication or installation is necessary.

DiamondGuard™ SRG
DiamondGuard® SRG (Scratch Resistance Glass) is a family of permanent protective coatings that provides glass with exceptional scratch resistance. In fact, glass with one of our DiamondGuard SRG coatings is proven to be over 10 times more scratch resistant than tempered and chemically strengthened glass.  Developed by Guardian’s Science and Technology Center using a patented process of diamond-like carbon deposition on glass, these coatings are not only renowned for their toughness, but their versatility and beauty as well.

Heat-Strengthened Glass
Wind load, thermal stress. Bring it on.  Heat-strengthened glass is less prone to spontaneous breakage than tempered glass. And it’s the product of choice, with the exception of instances where tempered glass or laminated glass is required by law, wind load, local or national building codes.

Tempered Glass
A glass that’s all about safety, even when it breaks.  Tempered glass is often referred to as "safety glass." And for good reason. It’s more resistant to breakage than normal float glass. And if it is broken, it usually breaks into relatively small particles, which are less likely to cause injury.

Laminated Glass and Security Glazing
When the going gets tough, our glass gets tougher.

Guardian produces Architectural Laminated Glass in a full array of thicknesses and sizes. It consists of two or more panes bonded together by a tough, durable plastic (polyvinyl butyral - PVB) interlayer (or interlayers).

If broken by impact, laminated architectural glass tends to remain integral in its frame, minimizing the risk of injury from sharp edges and flying or falling glass particles. It also strongly resists penetration by the impacting object.

Guardian laminated glass meets the current requirements of the ASTM E-1172 "Standard Specification for Laminated Architectural Float Glass," and is ideal for use in areas where building codes require hurricane resistant glazing.

Acclimate™ Residential Low E Glass (RLE)
Any climate, any time of year—one glass masters them all.

Climates can fluctuate dramatically throughout a single day – not to mention an entire season – costing you in utility payments and in the comfort of your living and workspaces.

Fortunately, the scientists at Guardian have developed a brilliant solution: Acclimate RLE Glass, the world’s most advanced low-emissivity glass. Compared with standard glass, it improves insulating performance by as much as 50 percent, and does equally well blocking unwanted heat gain. So, regardless of which way the climate turns, Acclimate RLE Glass stands up to it, regulating your interior environment every day, every hour, in every season.
