When using glass balustrades, it is your obligation to use the safety glass that has been designated to you.
The safety glass available can vary as toughened (tempered) or laminated.
Tempering glass is a process that the glass is subjected to consisting of heating the glass at a rough temperature of 700ºC and then quenching, otherwise known as cooling the glass quickly.
Quenching only takes about 1 minute – it creates a strong layer on the front and back side, simultaneously locking tension inside the glass. This makes is approximately four times strong to impact than regular float glass.
It is called safety glass because if it is shattered, it will not break into large pieces, with dangerous shards but rather into hundreds or thousands of smalls pieces, which are less dangerous.
Laminated glass is made from at least two glass panels with an interlayer. The interlayer is usually made of plastic or resin-based. Laminated glass can be made from two float panels, two toughened panels or a combination thereof.
Laminated and tempered glass use is slowly increasing, particularly on high rise buildings!
