Laminated Glass
Laminated glass has the same strength as ordinary glass but it consists of two pieces of glass containing a sandwich of a plastic interlayer. If the glass does get broken this interlayer holds the whole piece in place so there is no hole left in the window for an intruder to get in through for example or large free shards that can cut. It’s the same glass you find in car windscreens and shop fronts.
Toughened Glass
Toughened glass is up to five times as strong as ordinary glass which means that it has to be hit much harder in order to break, also when it does break it is into lots of small pieces which are much less dangerous. It’s the same glass that you will find in bus stops and phone boxes where you may have seen it smashed into small pieces on the floor.
