About Us

Clark Door is an independent company that designs, manufactures, services and installs acoustic doors, fire doors, temperature-controlled doors and industrial doors. The doors are designed and manufactured at our base in Carlisle, Cumbria and are exported worldwide to more than 45 countries.

Our History

Clark Door can trace its origins back to a timber merchant in Cranford, New Jersey, USA in the late 1800’s. The company developed and expanded into manufacturing doors, primarily temperature controlled doors for the cold storage industry. By the 1950’s the company had three manufacturing sites in the USA with later operations in Canada, Sweden and South Africa.

The UK factory was opened in 1973, Paul Ashley initiated a management acquisition of the UK Company in 1991 and today, Clark Door Limited is a family business led by Paul and Andrew Ashley; both qualified engineers with a passion for excellence. Clark Door’s Chairman Paul Ashley received an MBE in Her Majesty the Queen’s New Year Honours list of 2011, for services to manufacturing in Cumbria.
