About Roundbrand

Formed over 20 years ago to manufacture double glazed windows and double glazed doors to the trade and independent companies, the company embarked on an expansion programme in 1994 that added 2 further factories and 13 trade depots to its portfolio.

In 2005 the company opened its own “toughening plant” complete with furnace and the latest Willian production line. This enables the company to manufacture its own made to measure toughened glass as well as produce energy efficient argon filled double glazed units.

The parent company, Armthorpe Glass Ltd began life in 1974 as a glass merchant but now manufactures vacuum formed infill panels and double glazed sealed units. Their main customers are window companies.

Roundbrand operate from a 45,000 sq.ft freehold factory in Doncaster, South Yorkshire. Together they employ 80 people in a dedicated double glazing facility.
