Laminated Glass


Prel-Lam is made of two or more pieces of glass permanently bonded together with one or more interlayers of PVB resin. During the laminating process, the multilayer glass is placed inside a pressurized autoclave, and then subjected to a combination of strong air pressure and high heat. The process ensures permanent adhesion of the different layers and allows for the creation of an integral unit with excellent optical quality.


  • Protects people and goods in the event of breakage, as the interlayer holds glass fragments together
  • Meets safety glazing standards
  • Blocks 99% of UV rays which cause fading and discolouration of interior coverings.
  • Provides soundproofing that is superior to monolithic glass.
  • Makes it possible to create unique glass designs with decorative interlayers such as Vanceva® (contact us for more information).
