Our History in Window Units

The Story of 3 Symbolic Insulated Glass Units

At Clayton Glass we have a 56-year history of creating glass units to the highest possible standard. If you are a regular reader of our staff interviews, you’ll know about the pride that our factory floor staff take in their work, the sincere dedication they have to producing the most pristine of double glazed units.

Nothing summarises this better than the window unit you see in the background image here. This plucky IGU is a member of a family of three insulated glass units produced during an experiment all the way back in 2003.

in 2003, Clayton glass was a much smaller company. We were operating out of a smaller factory, dispatching fewer products to less customers. Around the time, we were experimenting with our double glazed units, by filling them with Argon gas…

The theory was, because Argon gas is denser than air, that it should therefore improve the thermal insulating properties of a glass unit. Excitingly, This theory turned out to be on the money.

The unit you see here was one of three argon-filled sample units, produced to the Clayton Glass standard. These three double glazed units were filled with Argon gas concentrations of 91.50, 92.30 and 93.20.

Fast-forward to 2019. Clayton Glass has now become one of the largest manufacturers of insulating glass units in the United Kingdom. Now operating out of 4 state-of-the-art factories with hundreds of customers and clients, and many more staff. We now dispatch many thousands of products a week and process tens/hundreds of thousands of tonnes of glass per year.

However, we have not forgotten where we came from. These Argon gas filled sample units, created in 2003, now contain Argon gas concentrations of 86.35, 86.55 and 89.20 respectively.

Each unit contained at least 93.7% of the Argon gas it was originally filled with 16 years ago.

At Clayton Glass we build our glass units to last, we always have, and we always will.
