Unrivalled Product Range, Exceptional Quality

Clayton Glass is a specialist glass manufacturer having benefitted from over £5m of investment in recent years. Not only do we excel in customer service and business operations, but also through our products range. Nor do we flog our capital equipment to the last performance percentage. We typically operate at 60-70% of full capacity, sow whatever the customer requirmenrs, we can fulfil them consistently each and every time.

We’re very much a leading IGU manufacturer and one of the largest independent ones in the UK. Typically we manufacture 13-15,000 units every week for some of the most trusted and respected names in the industry. We also have specialist divisions within the company serving other glazing sectors.

In addition to our IGU excellence, we’re also one of the leading names when it comes to glass units for the panel and composite door markets, helping our customers to boast UK manufactured units within their  entrance doors. Double and triple glazed units, leaded lights are all part of a very diverse range of door glass options.

Our SMARTGLASS brand is a market leader in the conservatory sector and there are a wide range of tints and performance levels within the range. We have also recently launched Ultra 86, at present the industry’s best performing glass for conservatory roofs, blocking 86% of the sun’s rays.

Finally, as a company with a global reach in terms of glass specification, we’re able to think outside of the box and have already tested the market with self-tinting glass technologies for conservatories and lantern roofs.

Specialist Products
This is SMARTGLASS Dynamic, a revolutionary self-tinting glass technology. It’s the ultimate in non-static glass, that blocks more of the solar rays than our marketing leading Ultra 86, yet is almost as clear as a standard IGU when there is no direct solar contact with the glass.
