Low-iron glass

Other glass is green with envy

Iron oxide is a common ingredient in standard glass because it lowers temperatures during the manufacturing process. As a result the glass carries a green tint. With recent advances in glassmaking, the iron oxide content can be reduced, achieving stunningly clear glass that transmits abundant light.

Low-iron glass can be used almost anywhere regular float glass is used, particularly in applications requiring increased visible light, reduced solar transmission and a crystal-clear appearance. So get ready for clean lines, true colours and breathtaking views with no distractions. With low-iron glass, it’s just your creativity and whatever you want on the other side.
