The glass that goes the extra mile

Standard clear glass has an inherent greenish colour due to its iron oxide content. This green tint is visible particularly when viewing the edge of the glass or in a composite stack of many glass lites. Guardian ExtraClear® float glass contains significantly less iron oxide than standard clear float glass, resulting in enhanced colour neutrality in transmission and reflection. Guardian ExtraClear® can be heat treated or laminated and has a wide range of applications including high performance facades, partitions, store fronts, solar control glass, laminated safety glass, and silk-screen printed glass among others.
