Low-Iron Glass
Ultra-clear glass manufactured with reduced iron oxide content, eliminating the green tint visible in standard clear glass, especially at thicker panels and edges.
Technical Details
Standard float glass contains approximately 0.1% iron oxide, which produces a noticeable green tint at panel edges and thicker dimensions. Low-iron glass reduces iron content to around 0.01%, achieving over 91% light transmittance compared to 83-85% for standard clear glass. This results in a crystal-clear appearance that accurately renders colors and maximizes transparency.
Frequently Asked Questions
Why does regular glass look green at the edges?
The green tint comes from iron oxide (Fe2O3) naturally present in silica sand used to make glass. This tint becomes more noticeable at thicker dimensions and when viewed at the edge.
Is low-iron glass worth the upgrade for glass railings?
For premium installations where visual clarity is paramount, low-iron glass is highly recommended. It eliminates the green edge tint and provides true color rendering, particularly noticeable in frameless and base-mounted railing systems.
