Thermal insulation for housing and small buildings – revised Standard published
Standards New Zealand has published a revised Standard specifying Thermal insulation – Housing and small buildings, NZS 4218:2009, which supersedes NZS 4218:2004.
NZS 4218 specifies thermal insulation requirements for housing and small buildings for users of the Standard – architects, designers, building consent authorities, and glaziers.
'The Standard is also useful for the building industry including glazing manufacturers, insulation manufacturers, and manufacturers and suppliers of building products so that they can provide advice and stock appropriate products,' says Michael Camilleri, committee Chair, from BRANZ. 'Ambiguities in the previous version of NZS 4218 have been resolved, and there is additional guidance with more worked examples.'

DZ 3122 Specification for Portland and blended cements (General and special purpose)
The aim of NZS 3122 is to specify requirements and methods for testing hydraulic cements consisting of Portland cement or of mixtures of Portland cement and one or both of fly ash and ground granulated iron blast-furnace slag. The outcome is to ensure that the end user of the Standard benefits from being up to date with current technology and in line with current industry methods and practices.

DZ 3123 Specification for pozzolan for use with Portland and blended cement
The previous edition of the Standard, NZS 3123:1974, specified the requirements for blended hydraulic cement comprising Portland cement and a pozzolan of appropriate type and quantity. NZS 3122:2009 now includes provisions for blended hydraulic cement containing natural pozzolan, superseding the NZS 3123:1974 provisions for Type PP cement. NZS 3123:2009 now only includes requirements for pozzolans that may be added directly to concrete or used to manufacture Type GB cement. Together, NZS 3122:2009 and NZS 3123:2009 reflect current technology and current industry methods and practices.
