NZ Safety Standards
AMN will not compromise on Glazing standards.
Within the glazing market, the key standard to abide by is NZS 4223 which deals with “Glazing in Buildings”.
NZS 4223.1&2:1985 Code of Practise
Parts 1 & 2 lay down the requirements and recommendations for the selection of glass for buildings, paying particular attention to loading, thermal control, and human impact safety as well as general design principles. Part 1 covers design and installation considerations for the general situation and deals with safety requirements. Part 2 relates specifically to sealed insulating glass units.
NZS 4223.3:1999 Human impact safety requirements
Part 3 looks at the minimum requirements for glazing in buildings in locations where it could be subject to human impact, with the intention of reducing the risk of personal injury.
NZS 4223.4:2000 Dead, wind and snow loading
Part 4 provides information on the determination of minimum glass thicknesses for vertical and sloped glazing in New Zealand governed by the limit state loadings. It supersedes the design requirements given in Part 1 concerning the selection of glazing for dead, wind and snow loading.
In addition a useful standard, which is referred to regularly in Part 3, is:
AS/NZS 2208:1996 Safety glazing materials in buildings
This standard specifies the functional properties of various safety glass, including toughened glass, laminated glass, wired glass, organic-coated glass and plastic.
