Pilkington Plateau™

Pilkington Plateau™

High quality glass for acrylic casting


Pilkington Plateau™ is high quality based float glass made to extremely tight tolerances, giving the glass a special flatness demanded by the acrylic casting industry as well as other uses. It is offered in a range of different finishes, clear, satin and textured, to provide a variety of cast acrylic sheet surface finishes. 

The standard thicknesses for Pilkington Plateau™ are 8 mm, 10 mm and 12 mm in both annealed and toughened form. Other thicknesses are also available on request.


Pilkington Plateau™ is ideal for acrylic casting and industrial applications.

  • Glass thickness tolerance maintained at a high level along with the wedge of the glass to provide a high tolerance glass mould
  • High strength glass (toughened) ensuring safety during use and longevity of the mould
  • Specially designed manufacturing system to ensure the best quality during production
  • Precision processing to ensure that the required high quality finish is maintained with minimal surface defects
  • High level of quality control ensured - each sheet of glass inspected for surface defects and uniform plate shape
  • Automatic shape-measuring machine used for pairing of similar glasses ensuring manufacture of high quality and tight tolerance acrylic sheets
  • Pairing and plate data supplied to allow repair of damaged glass
  • Can be made with an etched surface (satin, sheen or silk finish); 6 mm patterned glass also available as alternatives
  • Edge finish developed as a C profile to ensure longevity of the glass during manufacture and to reduce damage to glass edges



  • Pilkington United Kingdom has been supplying toughened glass to the acrylic casting industry since the mid 1930s when I.C.I. first developed the process of casting acrylic between two sheets of glass.
  • The glass used was toughened at the initial stages of development and is still mainly used today.
  • In the early 1950s a formal collaboration between I.C.I. and Pilkington United Kingdom was established.  
  • Joint development work was initiated and, by the early 1960s, led to a very much improved standard of flatness, glass thickness and edge control on the glass.
  • In the early 1960s we capitalised on the toughening expertise gained through working with I.C.I. by developing ‘Glass for Acrylic Casting’ export opportunities to bring forward the improvements.
  • Further manufacturing developments by I.C.I. in the early 1970s produced benefits in glass flatness and cost.
  • Initially Europe and the U.S.A. were the main markets followed quickly by development further afield in Latin America and latterly in S.E. Asia and China.
  • In the early 1990s the Pilkington Plateau™ Trademark was registered and the range was developed further to offer a specific named product to the market.
  • Today we have customers worldwide most of whom utilise the Pilkington Plateau™ toughened and etched range of glasses in their casting process.


  • Over the past few years the Pilkington Plateau™ product range has been widened to include a new acid etched finish called Pilkington Plateau™ Sheen
  • Development of further future offerings are being progressed with interested parties in order to produce the next generation of products for the market
  • We have developed a system where we can triple pair the glasses for customers in order to increase the capacity of their production lines – this is in conjunction with a product that you can use both sides


  • High strength glass (toughened) is used to ensure improved operator safety during use and also increased longevity of the mould
  • Pilkington has a bespoke manufacturing system to continue to supply the best quality of the product during production
  • Quality control ensures each sheet of glass for the mould is specially inspected for surface defects and also plate shape prior to manufacture and despatch
  • An automatic shape-measuring machine, allows for the pairing of similar glasses
  • This results in a quantifiable pairing tolerance for the glass mould being achieved thus allowing for superior acrylic sheets to be manufactured
  • The Pilkington Plateau™ mould’s pairing data can be supplied as well as the individual plate data should the need arise to re-pair damaged glasses
