How Do Laminated Glass Windows Work?

Laminated windows are a fairly new concept, having been around for just over a decade now. Many glazier services specialise in their installation and as these windows are manufactured in a way to ensure their longevity, they can last for decades with very few concerns when compared to other types of windows.

What is a Laminated Window?

A laminated window is a type of glass pane that has been heat treated, tempered and then coated in a durable, hard-wearing casing typically made from high-yield plastic or PVC. This layer begins its life in liquid form and is coated over the surface of a window. The layer is then exposed to temperatures of between 300 and 400 degrees Celsius, whereby the composition will solidify and create a smooth film.

What Can Laminated Windows Be Used For?

These types of windows are widely used within homes, commercial buildings and even newer models of vehicles. Because of the way in which they are manufactured, they can sometimes cost more than traditionally made windows and panels – but their high strength and durability can often more than make up for the additional expense.

What is the Purpose of a Laminated Layer?

Even with the latest advances in glass construction technologies, the material can still be brittle and prone to shattering from time to time. Modern glass is usually tempered to provide a higher strength to the panes – and if these windows ever break, they will often do so in pieces as opposed to shattering entirely.

Where heat treatment can add strength to a window and tempering can provide durability – lamination can act to further secure the structural integrity by reinforcing the shape and composition of the panel. Furthermore, if a break or shattering should ever occur – the laminated layer can act to securely hold the glass in place, or at the very least it should be able to stop it from splintering and going everywhere.

This can be especially beneficial within the windows of a home, as well as for cars. One of the main concerns over the use of lamination is the fact that a layer on either side of the glass can act to darken its tone. Too dark and the window can be difficult to see out of. Too light and the coating might not be enough to offer strength and restraint should the worst occur. Hiring a glazier to help with choosing the right type of glass can be helpful, as they will typically understand the composition of panes and how best to handle glass repair should the need arise.
