ExtraClear float glass is Guardian's standard clear float glass offering, unlike most other clear float glass Guardian's ExtraClear has a reduced iron content, this product sits half way between normal clear float and Low Iron glass and provides a better level of clarity with less discolouration (blue/green appearance) when viewed from the cut edge of the glass.


Low Iron float glass which has an almost crystal like appearance, the edge detail is almost completely clear with little to no blue/green discolouration.
