Laminated glass is another option used when safety glass is required. It can be manufactured using glass that is annealed, heat strengthened or tempered and can be made up using different glass types including: tinted, reflective, patterned, and or mirror. Laminated glass is produced by bonding layers of glass together under pressure and heat, with a layer of film, called the interlayer, in between them. The interlayer absorbs the energy impact and allows the sheet as a whole to flex and bend. Although the glass may break, the glass fragments remain firmly bonded to the interlayer, minimizing the risk of injuries and or provide resistance to the passage of persons or objects.
