AS1288 specifies the use of safety glass as a minimum for both residential and commercial buildings in Australia. Essentially there are two types of safety glass that we use at Nuline, laminated glass and toughened glass.
Laminated glass is essentially two layers of glass held together by a clear polyvinyl butyral (PBV) interlayer. It is because of this interlayer that when broken, laminated glass holds together in a characteristic ‘spider web’ cracking pattern (see image below).
Toughened safety glass
This type of glass is often used in shopfronts to prevent any potential burglars from getting easy access to inside. It is also readily available and easy to cut to size. As such, it is the glass that we use as standard. The second type of safety glass is called toughened glass (sometimes referred to as tempered glass). This type of glass goes through a controlled thermal process which makes the glass substantially stronger (up to five times) when compared to regular glass. It requires a significant force or a very sharp object to break. When this type of glass is broken it shatters into tiny little pieces (see image below) and is less likely to cause personal injury due to its blunt edges.
Both these types of glass are used to form tinted, patterned, performance (low E) and double-glazed glass units. They are also available in different thicknesses, but Nuline windows and doors will ensure that the glass meets the relevant Australian standards.
