Low- iron (extra clear) glass is made with a float technique, but is characterized by a much lower iron oxides content than a regular clear glass. This composition allows for a higher light transmission and reduces the green tint. It can be manufactured even in large size and in a wide range of thickness and can under go treatments and techniques like any other float product-for example, it can be tempered, laminated, frosted and ground.
The characteristics of low-iron glass are as follows:
high light transmission
light transmission is higher than clear float glass, with heavy thicknesses in particular (low-iron glass increases light transmission by 3-4%, reaching 7-8% with thicknesses above 8 mm)
enhanced glass aesthetics and brightness
it allows for a perfect colour restitution when observed through the glass surface
also available in 15 and 19 mm thickness
These features allow also for a greater natural internal lighting, which certainly explains why low-iron glass is architects’ favourite product.
With regard to its uses, low-iron glass is so versatile that it can be suited to an amazingly wide range of applications.
