Liquid Crystal Glass

Prel-Lam LC

Verre laminé

Prel-Lam LC  Liquid Crystal Glass:

  • Laminated glass that changes color with the flip of a switch:
    • On:  the glass is transparent
    • Off : the glass is opaque
  • Ensures the privacy of the occupants without the need for window coverings
  • Controls the entry of natural light and reduces glare
  • Can be used as a projection screen


    • Prel-Lam LC consists of laminated glass connected to an electrical circuit, controlled by a switch, that changes appearance depending on the position of the switch; when the electrical current is interrupted (off) , the glass is opaque; when the current is restored (on), the glass is transparent.
    • Includes a thin film of liquid crystal laminated between two sheets of glass.  When the crystals are electrically activated, they are aligned and one can see through the glass.  However when the electricity is turned off, the crystals become chaotic, making the glass opaque.
    • Operates at very low electrical requirements 


    • Glass doors and partitions
    • Conference rooms
    • Glass kiosks
    • Projection Screens
    • Etc.
