How Rear Windows Differ From the Front Windscreen

Whether you call it a rear window or rear windscreen, the large piece of glass at the back of your car is just as important to your safety and comfort, and that of passengers in your car. Although it is exposed to less flying debris than your actual windscreen, the rear window does still keep objects, and weather elements, out, while also supporting the frame of your car. But there are important differences between your rear window and your front windscreen.

Rear Window Construction

The size and shape of your rear window might be similar to that of your front windscreen, but even if they had the exact same dimensions, the glass is not interchangeable. If you ever call ahead to a windscreen replacement specialist to check if they have stock, make sure you don’t tell them your windscreen needs to be replaced. You need to tell them it is your rear window or rear windscreen that needs replacing.

Modern front windscreens are made from two layers of glass bonded together by a layer of laminate that makes them tougher and limits them from shattering when subjected to extreme force. But your rear window is made from tempered glass – commonly known as safety glass – much like all your side windows; it’s still quite tough but will shatter into small fragments that are less likely to cause severe injury.

Features of Rear Windows

Most vehicle windscreens look very similar, regardless of make or model of the vehicle, but rear windows can differ considerably. Some cars have a smaller rear window that isn’t as tall as that on other vehicles, some will have a wiper blade to help keep them cleaners, and some utes have a rear window made up of separate panels, with one panel able to slide open or open on a hinge.

But a more common feature, and one that means you always need to ensure you use a professional company to replace your rear window, is the inclusion of thermal defroster wires activated by an electric current. Those thin lines that run across your rear window from one side to the other – top to bottom – are used to help keep your rear window clear of ice and condensation. Even if you’ve never had to clear the rear window of winter frost, you would have noticed driving on cold or wet days, with your windows all up, causes many of the windows to fog up. Switching the rear defroster on heats these wires up, causing the condensation to evaporate, and allowing you to again see clearly out your rear window. It’s an important safety feature, and another reason to only use professionals to replace your rear window or windscreen.
