Glued glass (triplex)
Another way to protect against splinters generated when a window is broken is to use triplex - glued glass with a complex multi-layer structure.
Inside it is a transparent polymer film or a layer of special resin. If you hit such glass with a hard object, it breaks, but all the fragments remain hanging on the polymer base and do not harm the people nearby. Such multi-layer glass is often used in the manufacture of street railings or bulletproof windows. Among other things, due to their structure, they vibrate less under the influence of sound waves, which means that the sound insulation of the room increases.
