Install wall insulation

Check if you need a consent

You will need to apply for a building consent if you're installing insulation in:

  • an external wall
  • an internal wall that is a fire separation wall.

You don't need a building consent or a resource consent for any other insulation projects.

Our tip

If you need help to determine if an internal wall is a fire separation wall, contact us.

​Injected wall insulation

You may need a building consent if you want to inject wet insulation or water repellent dry fibre insulation into internal or external walls.

Examples of this product include foam, mineral fibre and other such products.

This will not include the use of non-repellent organic fibres, such as wool and paper.
