This type of glass is actually made up of a piece of plastic sandwiched between two layers of glass or a thin layer of vinyl between two layers of glass. The three layers are sealed together and any air pockets removed using rollers or vacuum systems. Then, the layers are heated to fully bond them together. A weblike cracking pattern protects passengers from flying pieces of sharp glass.
