The OP was asking for information about the rear screen.Laminated front screens became widely used in the 1980s. Toughened glass is still commonly used for side and rear windows. Only this evening I walked passed a Peugeot hatch back that is currently sporting a gaffer tape and bin bag rear window replacement. Smashed rear windows can be the product of slamming the hatch shut with stuff from the DIY warehouse sticking out of the opening. In the days when aftermarket radios and stuck on satnav had a value down the local pub it was a common sight to see side windows smashed into thousands of cubes or the tell tale signs in some car parks. A number of cars now come with laminated side glass, my S205 had laminated “acoustic” glass fitted to reduce noise to the cabin. On the side windows it’s easy to spot laminated glass by lowering the window and looking at the top edge. Laminated windows are a sandwich of two sheets of glass with a plastic film between them, if you look at the top of the glass you can see the layers. Identifying the construction of the rear glass is more difficult without key words, toughened or laminated printed on the glass. Sometimes you can identify toughened glass using polarised sunglasses, toughened glass often shows patterns of different colours due to the manufacturing process.
Hopefully someone with more knowledge will be along and can give a more helpful answer. Breaking toughened glass when trying to remove it certainly makes a mess and considerably adds to the cost of any work.
