Where to start
Find what you came for
The Association serves three audiences with very different questions. Each one has its own path in.
Builders and specifiers
Check a company’s membership before you engage it, confirm installation against NZS 4246:2016, and prove the R-value that went in.

Installers and businesses
Join the Association, enrol your staff in the training programme, and use the members area for compliance and technical documents.

What we stand for
Five commitments the Association holds its members to
Quality product
Products that meet New Zealand standards, declared honestly, and fit for the building they go into.
Quality installation
Installed to NZS 4246:2016 and to the New Zealand Building Code, because the product is only as good as the fit.
Training and capability
A structured training programme members enrol their staff in, building a career path rather than a headcount.
Energy efficiency
Warmer, drier, healthier buildings that cost less to run, across new build and retrofit alike.
Industry leadership
Lobbying government and key industry influencers, and speaking on behalf of the sector as one voice.
Tools
PROVE the R™
Measure a physical insulation sample and the calculator identifies its likely product range and R-value from IAONZ product data with its BRANZ appraisal source.
Built for installers, specifiers and assessors who need evidence rather than an assurance. Indicative only, never a certified figure, and the calculator shows when its data was last updated.
Training
The Association training programme
Members enrol their installers in the IAONZ training programme, validating knowledge and experience and building a career path in the industry. New course dates are added as soon as they’re set.
