County Durham-based Clayton Glass has acquired specialist glass manufacturer Romag, for an undisclosed sum. While the new deal brings together two of the North East's leading glass and glazing businesses under the same ownership, they will continue to operate as separate entities with their respective management teams operating "in completely distinct parts of the glass industry." Romag produces specialist glass products and security glazing laminates serving the building integrated PV, security, architectural and transport sectors while Clayton Glass Group, based in North Stanley, manufactures insulated glass units for the domestic sector and glass for conservatories. Combined, the new group will have turnover in excess of £40m, with over 400 employees.
