Ceramic Coating



Prel-Coat Spandrel Glass:

  • Opaque glass lites mainly used in non-vision sections of curtain wall. The panels are located between sections of transparent windows and are used to hide the structure parts which shouldn’t been seen from the exterior.
  • Prel-Coat ceramic frit coating offers outstanding resistance to :
    • crackings
    • scratches
    • fading
    • chemical products
  • Offered in a choice of 14 standard colors, custom colors can also be developed from samples provided by the designer


  • Prel-Coat ceramic coating is applied on the surface of the glass using a horizontal roller applicator.  The glass is then heated in a furnace at a temperature of about 621°C (1150 F).  This treatment fuses the ceramic to the surface of the glass.
  • Once the heat treatment is completed, the ceramic coating is extremely resistant to cracking, fading as well as chemical attacks.

Glass makeups

  • Monolithic Glass : The ceramic coating is applied on surface #2 of the supporting lite. The glass must be heat strengthened or tempered.  It is not recommended that the ceramic coating be exposed to the elements therefore using surface #1 is to be avoided. A security film can be applied to the back of the spandrel glass. If it is broken, the film will provide temporary retention of the broken shards of glass.
  • Laminated Glass : The ceramic coating can be applied to surface # 2, 3 or 4 of laminated glass. All the lites that make up the laminated glazing must be heat strengthened or tempered.
  • Insulating Glass Unit : The ceramic is usually applied to surface # 4 of insulated glass units. The two lites that make up the unit must be heat strengthened or tempered.
