Laminated glass (sometimes called toughened laminated glass) comprises two or more layers of glass sandwiched together by tear-resistant plastic film interlayers (usually polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA).

The aim is to create a glass composite which can absorb the energy of a person or object which strikes it, preventing penetration of the pane and also any potential injuries that might result from flying fragments of broken glass. An additional benefit of laminated glass is that most ultraviolet radiation can be blocked by the PVB or EVA interlayer. Thermoset EVA layers can block up to 99.9% of UV rays.

= Applications =

Laminated glass can be used for safety or security reasons. It is used for architectural applications where for example, the glass could fall from a height and shatter, and also for roof, balcony and terrace balustrading, as well as for skylights. It can also be employed as a decorative material due to the wide variety of interlayers available, e.g coloured, textured, meshed or patterned. In addition to flat sheets, it can be supplied in curved sections, as may be required for car windscreens. It is especially useful for windows and shopfronts in areas prone to hurricanes.

= Manufacture =

Bonding together the alternating layers of (typically annealed) glass and plastic film is usually achieved through the use of heat and pressure that is created by an autoclave.

Manufacture can involve using heat-strengthened glass, which when breaks does so into large pieces but will be held in the frame by the PVB inter-layer. Or it can be made from tempered glass, where the sheet may fall out of the frame but will mostly stay together due to the interlayer. Digital printing for special effects can be created by printing on to the glass prior to laminating or printing onto the interlayer.

= Configurations =

Laminated glass is available in various thicknesses and configurations. A typical glass-layers configuration can comprise 2.5mm glass – 0.38mm interlayer – 2.5mm glass, resulting in ‘5.38 laminated glass’.

Thicker glass and multiple laminates giver a stronger product. Thicker configurations such as double– or triple-laminate with interlayers (int) can include the following:

=== Double laminate: ===

* 6mm - int - 6mm.
* 8mm - int - 8mm.
* 10mm - int - 10mm.

=== Triple laminate: ===

* 6mm - int - 6mm - int -6mm.
* 8mm - int - 8mm - int -8mm.
* 10mm - int - 10mm - int -10mm.

The cockpit of an aircraft such as a Boeing 747 may include a triple-laminated glass construction comprising three layers of 4mm toughened glass with 2.6mm PVB layers in between, making a total glass thickness of 17.2mm.
