Almost all windows have glass panes. Traditionally,
these panes are made from pure glass, which makes them fragile and prone to
breakage when hit by a hard object. This is why glass windows are often the
entry point of burglars into a house. Thanks to advancement in glass production
and window
tinting technology, however, glass panes can be made less fragile and more
reliable.
Protection Against Injury and Burglary
Window glass comes in many types, including
annealed glass, float glass, and heat strengthened glass. While most of these
glass window types have beneficial features, they share a common weakness—they
break into sharp shards when smashed by a hard object. A lot of injurious and
sometimes fatal accidents have been associated with glass shards.
One way to prevent glass windows from breaking into
shards is to temper it. Fully tempered glass can break into small pieces when
subjected to a certain level of force. Unlike shards, however, these small
pieces can hardly cause injury to anyone who gets in contact with them.
However, it brings up another issue—security. When a glass window easily breaks
into small pieces, it becomes easily target for burglars.
