Triplex Holdings
1958 Triplex Holdings was established to hold the various subsidiaries; Triplex (Northern) Ltd was sold to the new subsidiary Triplex Safety Glass Co[1]
1962 Plastics manufacture ended at Willesden.
1965 Pilkingtons owned more than 50 per cent of Triplex which then became a subsidiary of Pilkington.
1967 Triplex acquired British Indestructo Glass where production of glass soon ended.
1968 Opened new R&D centre in King's Norton, Birmingham. [2]
1970 Aircraft activities were organised in a separate division; orders had been received for the Airbus and from the Japanese aircraft industry and production orders were expected for Concorde; the engineering companies had achieved highest ever turnover, including a major order for a conveyor for British Leyland; this helped to offset the poor results of the Safety Glass company[3]
1972 Pilkington acquired the remaining shares in the company[4]
