Laminated Glass
Laminated glass is a safety glass that is held together by an interlayer of PVB, this ensures that in the event of breakage it does not shatter into large sharp pieces.

Double Glazed Units
Double glazing is a type of window where multiple panes of glass are assembled into units. Double glazing has become popular due to its heat retaining properties as well as for being far more secure.

Toughened Glass
Toughened glass is glass that has been strengthened by controlled thermal or chemical treatments. It will usually shatter into small pieces rather than sharp shards when broken, therefore less likely to cause severe injury. The applications toughened glass is used in are passenger vehicle windows, glass doors and tables, diving masks and various types of plates and cookware.
