JNS low iron glass is intended for applications that require a high transmission value and low coloration.  Some low iron glasses are patterned and offer unique characteristics for the lighting and solar markets.  Low iron glasses have similar chemical composition and properties as soda-lime float glass except the iron oxide content is significantly reduced, providing a less “greenish” tint.  JNS Glass & Coatings can provide any of the manufacturer’s products that are commercially available, including Starphire™, Optiwhite™, Diamant™ and UltraWhite™, Solite™, Solatex™, Pixels™, and C-73 Prismatic™.

JNS Glass & Coatings stocks Starphire® glass in a range of thicknesses from 1/8” thick to ½”. Starphire® glass is an ultra-clear soda-lime float glass product.  Starphire® has high visible light transmittance (>91% at 6 mm) and its brilliant azure edge are two characteristics unique to Starphire® glass. This glass is a low iron composition with mechanical and physical properties similar to ordinary clear soda-lime float glass.

JNS Glass & Coatings stocks Krystal Klear™ glass in a range of thicknesses from 1/8” thick to ½”.  KRYSTAL KLEAR™ is ideal for commercial and specialty applications.  It is a clear product with a slight straw color and is popular for appliance, lighting and solar applications.

JNS Glass & Coatings stocks Optiwhite™ glass in a range of thicknesses from 1/8” thick to 3/4”.  Optiwhite™ is a low-iron extra clear float glass with very high light transmission. It is practically colorless, and the green cast inherent to other glasses is not present. Optiwhite™ supplied by JNS is therefore ideal for use where glass edges are visible or where a neutral colour is desired.
