Laminated glass is a safety glass made by laminating two or more sheets of equal/unequal glass thicknesses with a flexible plastic interlayer or PVB (poly vinyl butyral). The glass and interlayer are bonded together by heat and pressure. Generally this interlayer is 0.38mm thick but other thicknesses are available.
The safety aspect of laminated glass is due to its PVB interlayer which prevents the glass from disintegrating if broken, the glass adhering to the interlayer depending on the severity of the impact.
Laminated glass also acts as a barrier against penetration. Laminated glass is also available in tinted form. Tinted laminated glass simply uses a coloured interlayer between clear glass which also assists in reducing solar heat entry.
