What is laminated glass?

Laminated glass is a type of safety glass that remains intact when shattered. When broken, it is held in place by an interlayer, typically polyvinyl butyral (PVB), between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp, dangerous shards. This produces a characteristic ‘spider web’ crack pattern when the impact is not enough to completely pierce the glass.

Laminated glass is normally used when there is a possibility of human impact or where the glass could fall if shattered. Skylight glazing and automobile windshields typically use laminated glass. It is also used extensively in shop fronts, curtain walls and windows. The PVB interlayer also gives the glass a higher sound insulation rating, due to the damping effect, as well as increased protection against UV radiation.

Manufacturing process

The raw glass is scrubbed clean to remove any impurities, after which the first sheet of quality float glass is fed along the laminating line. A PVB interlayer is drawn over the first sheet of glass and a second sheet of glass is then placed on top of the PVB to create a 'sandwich'. This 'sandwich' passes through a specialised press and heating process which removes most of the air and effectively fuses the three items.

The laminated sheets are then stacked in a specific configuration for loading into an autoclave. Finished laminated sheets are stacked in a dedicated laminates warehouse.

A silver metallic coating can be applied to a surface of high quality float glass, by the magnetron sputter process in order to enhance the solar heat eliminating properties of laminated glass.
