Safety Autoglass

Another common question for our phone staff is: “What is Safety Glass, and do I have it?”
Almost all vehicles produced from November 1986 onwards require a laminated safety glass for the front windscreen.
This glass is 6.38mm (a minimum requirement), and consists of three separate layers:
A layer of 3mm glass, then a .38mm layer of PVB safety plastic, and another layer of 3mm glass.
The three are “sandwiched” together in a special process called “laminating”.
This process makes the final product very strong, and safe.
The major difference of this type of glass to the older version is the way in which the glass breaks when damaged.
Laminated safety glass will chip or crack.
When damaged star-like shapes will form on the outer layer of glass. The worst case scenario for this type of glass is a large line or crack appearing.
The older glass “toughened” glass is sometimes till referred to as safety glass, however it consists on one layer of glass, heat treated to make it strong.
This type of glass will completely shatter on impact leaving zero structural integrity, and worse still: leave a bunch of sharp shattered glass.
Thankfully, this older version of glass in windscreens is no longer legal in vehicles later than 1986.
All of the windscreens we sell are laminated safety glass except where expressly stated E.G Vintage & classic cars.
