    • Supercontryx is cut to size on request.


Isolated inclusions are accepted up to 2 mm. Inclusions smaller than 0.1 mm are not taken into account. Veins visible to the naked eye through direct observation in normal incidence are not allowed. Polishing according to Building Quality for more details, please refer to Corning SAS procedures.

Standard Shaping

  • rough cut edges
  • all sharp edges polished
  • corners rounded-off
    • Other shapings on request


  • Double glazing unit (DGU)
  • Laminated assembly

Special Applications

Glove box panels :

For this application, Supercontryx glass is supplied assembled with normal glass and drilled to allow the installation of glove rounds.

Cobaltherapy :

Several Supercontryx sheets can be assembled.
For thickenesses over 48mm, Supercontryx can be replaced with lead glass slabs.
