Low-iron glass – clearly different

Standard clear glass is actually far from clear. That’s why Guardian created UltraWhite. From the moment you see it, you’ll know what true clarity really looks like. The virtual absence of color makes UltraWhite glass the natural choice when neutral 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. UltraWhite can be tempered, laminated and painted just like regular float glass and can be used virtually anywhere regular float glass can.

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 adds distortion-free vision to the strength and security of laminated glass for unparalleled performance.
