Toughened Laminated Glass

General

Laminated glass is constructed from two or more panels of glass, sandwiching an interlayer and bonding the glass together. Should the glass be broken the main function of the plastic interlayer is to retain the broken glass in situ. Typically, laminated glass is constructed using annealed glass which has not undergone any thermal heat treatment to increase its overall strength. Standard laminated glass is therefore just as susceptible to breakage as annealed glass.

To overcome the strength issue of laminated glass, suitable toughened flat glass can replace their annealed counterparts. The result is a product that has the strength of toughened glasses (approximately five times that of annealed) and the containment of laminated.
