CM Glass Ltd stock, supply and install glass for use in high risk areas such as bathrooms, stairs, balustrades, doors and glass furniture.

There are two types of safety glass; laminated and toughened. Grade A Safety Glass complies to New Zealand Safety Standards NZS 4223:Part 3 and AS/NZS 2208.


Laminated glass consists of two or more sheets of glass permanently bonded together by a resin or plastic interlayer. This bond keeps the glass intact when broken. This characteristic significantly reduces the likelihood of serious injury. Such glass qualifies as Grade A Safety Glass.
Laminated Glass is a good choice for both safety and protection. It also has other uses such as noise control, climate control and UV protection. It can be produced in a range of colours and tints with minimal visible distortions.
CM Glass carry Waikato’s largest range of laminated glass, in stock, in thicknesses up to 13mm, and in clear, tinted, coloured, energy-saving and obscure.


Toughened glass, also referred to as tempered glass, is glass that has been thermally toughened. Glass is heated to temperatures of around 650°C where it becomes plastic-like. The glass is then rapidly cooled which induces high compression stress on the surface with tension in the centre. These additional stresses cause the glass to have increased thermal and mechanical strength. Toughened glass can be up to 5 times stronger than ordinary glass.
