Description

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.

Low-iron glass development began in the early 20th century, with Frank Lloyd Wright's Fallingwater (1939) being one of the first architectural applications. Modern manufacturing processes refined in the 1990s enabled consistent production of ultra-clear glass with iron content below 0.01%. Australian market adoption accelerated in the 2000s with increased demand for frameless glass installations and solar applications.
