The benefits of laminated glass

Thursday 22nd November, 2018

As we approach Christmas, retailers up and down the country are unveiling spectacular window displays. From food and fashion to gifts galore, these glittering sights can all be viewed through laminated glass shop fronts.

Laminated glass, along with toughened glass, is a type of safety glass. Laminated glass consists of two pieces of glass, usually 3mm thick, which sandwich a plastic interlayer typically made from polyvinyl butyral (PVB). During the glass manufacturing process, the glass panels and plastic interlayer are bonded together using heat and pressure. When laminated under these conditions, the PVB interlayer becomes optically clear, binding together the two panes of glass into a single unit. This double-layered design creates a high level of safety. In the event of the glass getting broken, the interlayer holds the loose shards together, minimising the risk of injury; whilst its ductility and toughness prevents cracks from passing from one side of the laminate to the other. This safety feature makes laminated glass ideal for one of its most prevalent uses in vehicle windows. It also serves to enhance the security attributes of laminated glass for applications such as shop windows: as the glass holds together there is no hole left for intruders to climb through.

Laminated glass has the same strength as ordinary glass but because of its layers it is more resistant to shock or damage through impact or high temperatures. As it is less likely to break, replacement costs are minimised or reduced. Its strength and reliability are reasons why laminated glass is popular in both residential and commercial settings, eg for shop fronts, skylights, ground floor glass doors and windows. Another reason why laminated glass is favoured is the level of insulation that it offers. Laminated glass is thicker than other varieties of glass, such as toughened glass, and therefore acts as a protective barrier against strong winds and heavy rain whilst providing better heat insulation and improving energy efficiency. The thickness of the glass can also contribute to sound reduction and higher levels of UV resistance than ordinary glass.

For the design-conscious, colouring can be applied to the PVB interlayer, creating a protective yet stylish feel for glass shower screens, glass partitions and glass shelving; and fulfilling a practical function for security glass.
