Low-iron glass is a type of high-clarity glass that is made from silica with very low amounts of iron. This low level of iron removes the greenish-blue tint that can be seen along the edges of clear glass.
Low-iron glass provides maximum brightness and clarity with a higher visible light transmittance than traditional clear glass. It is primarily on the edges where this difference is most noticeable, with clear glass having a greenish-blue tinge. Low-iron glass is often used when a coloured interlayer is incorporated into laminated glass.
The difference between clear glass and low-iron glass in isolation is minimal. However if they are put side by side in a balustrade the difference is obvious. The difference between clear and low-iron glass is more obvious in a balustrade than in windows. In a balustrade the edges of the glass are visible, whereas in windows the edges are hidden in the sealed unit.
For those looking to back-paint their glass, or match an exact colour, low-iron glass should not be overlooked. For example, a white interlayer in clear toughened & laminated glass will end up being a very pale mint green. Although this is only really noticeable when it is put next to something pure white.
All our glass we supply is manufactured to order. You don’t have to try and make stock panels fit your project. Whilst this might not sound like much, it is the difference between good balustrade and a great balustrade! Manufacturing to order also allows us to include any holes or notches needed for the balustrade.
