History

The Triplex Safety Glass Company Ltd was founded in 1912 by Kent-born Reginald Delpech (30 March 1881 - 29 May 1935).[2][3] The company was established in 1912 to build laminated windscreens in Britain, under French patents.

On 9 September 1929 Triplex formed a joint venture company with Pilkington in St Helens.[1] The company is now part of Pilkington Automotive.[4]

In the 1960s Triplex bought its main competitor British Indestructo Glass, giving it a monopoly in British laminated glass production.

In the 1980s, around 1,000 people worked at the Triplex site in St Helens and about 700 at the site in Kings Norton.

Pilkington retired the Triplex brand in August 1993. The company was formally dissolved in September 2019.[1]

Key people

Structure

The company was headquartered at Eccleston, St Helens, at a factory built in 1928. It had its main plant at Kings Norton in the West Midlands.

The St Helens factory now manufactures under the GKN (Aerospace Transparency Systems) brand. Aerospace glass continues to be made at the site. It is believed that the automotive building fell out of use with the collapse of MG Rover in 2005 (when Pilkington downsized operations), although closure quite possibly predated this.

Products

Triplex made laminated and toughened windscreens and windows for the automotive, rail, marine and aerospace sectors. Particularly widespread is the use of so-called "triplex" adhesives, which result from the bonding of two or more glasses – single or safety – usually via polyvinylbutyric (PVB) membranes. The glazing is welded by heating and later pressing.

Triplex glasses exhibit the maximum impact resistance. This glazing system is distinguished for the optimal use of safety in use since, if it breaks, the glass pieces are held in place by means of the intermediate membranes, preventing serious injury.
