Guardian ExtraClear®

Guardian ExtraClear® glass contains less iron than standard float glass. This greatly enhances the color neutrality and also natural light transmission – to offer clearer, cleaner, more natural views wherever it’s positioned.

Showing the extra mile

Standard glass has an inherent green tint due to the presence of iron oxide. In contrast, the reduced iron content of Guardian ExtraClear glass is able to deliver outstanding color neutrality – both in terms of light transmission and the reflective appearance.

Truer views wherever you look

Guardian ExtraClear® is used as a base glass for many other Guardian products, which means it has a very wide range of applications. These include high performance facades, partitions, solar control glass, store fronts, safety glass and printed glass.

Truer views wherever you look

Easy to work with

Guardian ExtraClear® glass can be processed, heat treated, laminated, cut, painted, silk-screened and is also bendable like any conventional float glass. Making it highly adaptable.
