Quick answer: Low-iron glass is float glass manufactured with reduced iron oxide content, eliminating the greenish tint of standard glass. The result: ultra-clear glass with VLT up to 91% and no color cast. Used on Florida commercial applications where view clarity and accurate color rendition matter — upscale restaurants, jewelry retail, art galleries, museum displays, hotel lobbies.
Standard float glass contains iron oxide that creates a green tint visible when looking through the glass edge or when light passes at oblique angles. Low-iron glass (also called 'ultra-clear' or 'water-white') removes most of the iron, producing a colorless appearance with VLT 90-91% (vs 84-87% for standard).
Pilkington Optiwhite, Saint-Gobain Diamant, AGC Krystal Klear (Cricursa fabricator in Florida), Vitro Starphire. Each manufacturer offers similar performance with slight cost and availability differences.
Low-iron glass costs 15-25% more than standard float glass on the same thickness and treatment. The premium is justified on applications where the visual clarity is the design driver.
Upscale restaurant storefronts (clarity to dining room and view to outdoor patio). Jewelry retail (accurate color rendition for diamonds and gems). Art galleries and museums (no green cast distorting artwork). Indoor-outdoor folding walls (seamless visual continuity). Hotel lobby walls (brand-quality finish). Wine cellar fronts (showcase clarity).
Skip low-iron on standard office, school, healthcare administrative, and budget commercial — the cost premium is hard to justify when view clarity isn't the primary design objective. Skip on spandrel applications (you can't see through it anyway).
