Anatomy of Your Car Windshield

Car Windshield

This article describes how a car windshield is made and how it is actually much more complex than it may at first appear.
Anatomy of Your Car Windshield
If you’ve been in a car accident and you find yourself needing auto repair, then chances are that one of the main areas to get damaged was your car windshield. Of course a car windshield is made of glass while the majority of the body is made of various metals, so it makes sense that this would be the first area to break.
But if you were thinking that that’s all your car windshield was – just a sheet of glass – then you would actually be very wrong. There’s much more to a car windshield and they tend to have a much more complex design, which is precisely why you can’t just fit in a new piece of glass yourself. To give you an idea of what’s actually involved in your typical car windshield and of just how complex they can be, read on for the full low down.
Of course there is some glass involved in a car windshield, but actually there’s more than one pane. Rather a car windshield is made up of two identical sheets of glass that are the precise same shape and pressed closely together with a thin film of laminate plastic in between.
The purpose of this is that it provides you with extra protection. Say a stone were to fly up and hit your window, it would need to do so with enough force to go through both panes of glass in order to get through and cause a problem which makes those car windshields much safer.
Meanwhile, because the two layers of glass are pressed tightly together, this means there’s also a layer of air between the glass, which acts as an insulator keeping the car much warmer than it otherwise could be and saving you on heating. This is also how double glazing works in residential properties which means it can also keep sound out and moisture.
Finally, that layer of laminate plastic can also serve to hold any shards of glass in place should your window shatter. This way you won’t have large shards of glass flying inwards into your car – instead they will just hang in position or you will see spider-web shaped cracks form across the glass without any actually becoming lose.
Other Elements
Depending on the type of car and windshield you may then also have other elements involved in the design of your window. These can include such things as tints for the colouring which can help to block out certain wavelengths of light and thus prevent glare from distracting you when you drive, or wire meshes which can be heated up in order to melt ice and remove steam which can otherwise obscure your vision when driving.
Meanwhile the type of ‘glue’ that is used to hold the windows in position is also very specific and not the kind of glue you might have in any of your drawers. This glue works by bonding the very particles of glass to your car at the atomic level and this way provides a hold that won’t allow any water to come through or for the window to fall out completely in almost any scenario or car collision. Just like the rest of your car, the windshield has more to it than meets the eye, treat it well!
