Overview
Executive summary
Low-iron glass is a premium float glass variant manufactured with reduced ferric oxide content (0.01% vs 0.1% in standard glass), eliminating the greenish tint characteristic of standard float glass. Available in thicknesses from 4mm to 19mm, it delivers superior light transmission up to 91.5% and crystal-clear aesthetics ideal for high-specification architectural applications, solar panels, display cases, and frameless glass installations.
