What's it like?

You would fit insulation around pipes, boilers and ductwork to help them retain heat. You might carry out jobs in factories, offices, power stations or on ships.

On a job, you would typically:

  • Plan where to put insulation by referring to building layout diagrams
  • Decide what materials to use
  • Prepare and clean the surfaces to be insulated
  • Measure and cut insulation materials to size
  • Fit insulation using clips, adhesives or cement
  • Seal the work area after completing the installation

You may also work on the removal of old materials such as asbestos. This substance is dangerous. Your job would involve other risks as well, such as working at heights, so it would be very important to follow health and safety rules carefully.

Working conditions


You would normally work 40 hours a week, Monday to Friday. You may do overtime to meet deadlines.


Your working conditions could be cramped, hot, dirty and dusty, and some jobs involve working at heights. This job may occasionally require you to work with hazardous substances like asbestos. In cases like this, you would be provided with protective clothing and equipment.


You would travel from site to site, which could mean overnight stays away from home for days or weeks at a time.
