No glass is shatterproof, and even bulletproof glass will crack under the impact, but since most desks made of glass have the shatter resistant glass as the main selling point, it might make sense to see how it works. The main two types of shatterproof glass are laminated glass windows and polycarbonate window panels. The laminated glass windows are actually two panes of glass that are connected by a thin piece of transparent film. If you have thick enough glass that is hard to break, it can be very difficult for intruders or impacts to break them. Additionally, the film is designed to stop the glass from shattering inwards and being a danger to people. Polycarbonate panels look like window glass, but they are made out of acrylics, polycarbonates, and other types of plastic. This makes them much more durable and they tend to bend under attacks and not break under them. They are the closest thing to shatterproof glass that we have, and it’s even what bulletproof glass is made out of.
