Safety glass maker, of Park Royal, London

1929 incorporated as a public company to manufacture safety or laminated glass.

1939 the company began to make flat toughened glass.

1949 Extended its production of toughened glass to curved glasses; Pilkington claimed that the automatic furnace infringed patents held by St. Gobain and itself. Settlement involved taking a sub-licence from Pilkington (as St Gobain's United Kingdom licensee) under one patent and a licence under the other.

1951 After a period of losses, the Austin Motor Co. Ltd., Briggs Motor Bodies Ltd., Ford and Pressed Steel Co Ltd. provided additional capital by taking up an issue of debentures which gave them voting control.

Early 1960s both BMC and Ford obtained about one-third of their safety glass from the company

By 1965 was importing half of its glass needs from Belgium

By 1966 the company supplied about 11.5 per cent, by value, of the UK demand for safety glass.

1966 discontinued the production of laminated glass

1967 Triplex Safety Glass Co acquired British Indestructo Glass where production of glass soon ended.
