What's the job really like?
Attention to detail key to doing a good insulation job
“When we get a job to insulate a house, we get here in the morning, we get a jobs card to tell us how many metres we need to take with us of what materials. Then we load the trucks up and go out to the house.
"We look for all the hazards. Downlights in the ceiling are a big one, and heating sources like chimneys and flues. The potential of burning a house down is possible, so you've got to be careful and you have to know how to put it in properly so that it reduces the risk of fires."
A physical job, a little dirty, a little cramped, but enjoyable
“It is a physical job – you get dirty. You have coveralls, or overalls, that you can put on. A lot of guys don’t wear them in the ceiling, just because you get too warm, but if you’re in the under-floor, you always wear your coveralls because you’re basically lying on the dirt.
“Our safe working height for ceilings is 700 millimetres, which is not that high. So, if you don’t like being on your hands and knees or crawling through a ceiling then you probably wouldn’t like it. But I’m used to it now that I’ve been working here for almost a year, and I enjoy the job.”
There are no specific entry requirements to become a building insulator, as you learn skills on the job.
However, most employers prefer you to:
- have a driver's licence
- pass a drug test
- agree to a pre-employment police check.
You may choose to complete the Insulation Association of New Zealand's (IAONZ) training programme for building insulators, which involves on-the-job training and theory.
There are no specific secondary educational requirements, but NCEA Level 1 is recommended.
Building insulators need to be:
- able to use their initiative and display good judgement
- able to work well with others
- good problem-solvers
- accurate and able to do basic maths.
Basically you just need to be able to work well as part of a team and be prepared to work hard.
Useful experience for building insulators includes:
- building industry work such as carpentry
- general labouring work.
Building insulators need to be fit, healthy and strong, as the work involves climbing and lifting. They also need to be comfortable working in confined spaces and at heights, as they may need to crawl through small spaces under buildings and above ceilings.

What are the chances of getting a job?
Insulation plans and building boom mean good demand for insulators
Insulators are in demand due to:
- the Residential Tenancies Amendment Act, requiring all rented homes to be insulated by 2019
- the Warm Up New Zealand: Healthy Homes scheme, which funds subsidised insulation for some rental properties occupied by tenants on low incomes
- a lack of suitable workers applying for building insulator jobs
- a construction boom, including the Christchurch rebuild, which is predicted to extend until at least the end of 2017
- the extra 22,000 houses that are needed over the next 10 years in Auckland, which will generate work for building insulators.
However, like many building jobs, this role can be affected by economic conditions. A downturn in the economy can lower demand for building insulators.
Some insulation work is seasonal
Demand for insulation refits in existing homes tends to fall in spring and summer, with about half as many homes insulated in this period, compared with autumn and winter. Because of this, it's harder to get this kind of work during the warmer months as insulation companies cut back on hiring.
However, insulation companies specialising in new buildings have year-round work.
Building insulators work for private companies
Building insulation companies range from small businesses with only a few staff, to businesses that employ 100 people or more.
