What is low iron glass?

When discussing the type of glass used for acoustic glazed partitions, one question we're often asked is, "what exactly is low iron glass?"

So, with the help of our Director, Oliver Davies, we're answering that question in this blog and discussing scenarios in which low iron glass is commonly used.

What is low iron glass?

Put simply, low iron glass is what the name suggests - glass with a lower iron content than standard clear glass.

Low iron glass is made from a special silica sand that has naturally lower iron levels than clear. It's this lower iron content that provides the colour neutrality and all but eradicated the slightly green-ish tint found in clear glass.

Where is low iron glass commonly used?

Typically, we see low iron glass specified in scenarios where a light coloured manifestation is required or a digital print graphic is going to be applied to the glass. This is to ensure the true colour of the film is portrayed.

For example, a white coloured manifestation will appear slightly green on clear glass, whereas low iron glass will show the true colour.

Furthermore, the clarity of low iron glass means it's often used in cases when natural light is being utilised within an office space.

What are the cost differences between clear and low iron glass?

This is difficult to answer as it varies on a project by project basis.

However, the general rule of thumb is an approximate 35% difference in cost between clear and low iron glass.
