North East manufacturer Clayton Glass has acquired factories in Scotland and England from French construction materials giant Saint-Gobain in a move it says will ramp up the company's production capacity.

The undisclosed deal sees Stanley-based Clayton, which employs about 450 people making glass units for the residential market in the º£½ÇÊÓÆµ, take over Saint-Gobain º£½ÇÊÓÆµ & Ireland facilities in Motherwell and Canterbury.

It means the firm will now be able to produce more than 65,000 units a week, including a mix of standard insulated glass units and specialist roof and door products.

About 140 staff at the two factories will join Clayton, which says the sites turnover roughly £17m per year - increasing the Clayton business by 35%.

A statement from Clayton Glass read: " With this latest investment, Clayton Glass consolidates its position as a unique, owner-managed six-site operation; the largest of its kind in the º£½ÇÊÓÆµ, and widely recognised for its innovative approach to all aspects of insulated glass unit supply."

The firm, which also runs a North Shields site, said the move would improve its ability to deliver to the whole of the º£½ÇÊÓÆµ, from the south coast to the north of England.

Clayton was established in 1956 and has grown to become one of the º£½ÇÊÓÆµ's largest independent glass producers, processing 25,000 tonnes of glass each year.

Latest accounts for the business show operating profit increased from £18,979 to £1.7m in the year to December 31, 2021, on increased turnover of £43.9m.

Writing in the accounts filed at Companies House, managing director Ryan Green said Clayton expects to see 38% growth in 2022, both organically and via acquisition.

He said the firm's partnership with Northern Express Glass Ltd continued to bring benefits and remained a key part of its future growth strategy.

In 2020 Clayton secured a £2m funding package to fuel growth, following its acquisition of Global Glass.
