Why and When is Laminated Glass Used?

Laminated Glass, a type of safety glass, features a Polyvinyl-Butyral (PVB) interlayer bonded between two or more glass plies using heat and pressure to form a single unit to provide protection against injury by glass due to it collapsing or through falling through the glass. The glass plies may be of equal or unequal thickness.

Laminated glass is a durable, high-performance glazing product, designed to remain integral in the opening should glass damage occur. Laminated glass will not shatter or collapse under normal bodily impact, it retains its integrity within the frame as the interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces.

It is available in various forms for glazing applications and can be tinted or feature a pigmented interlayer. This type of glass is generally used when there is a possibility of human impact, where the glass could fall or for architectural applications. Typical applications for toughened laminated glass include, skylight glazing, frameless glass balustrades, windows for sound proofing, glass Juliet balconies, glass staircases and walk on glass.
