Install wall insulation

Check if you need a consent

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

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

You do not need a building or 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.

Before you apply for a consent to install injected wall insulation

We recommend that the insulation installer completes and submits the application on your behalf.

You will need to supply a letter authorising the installer to act on your behalf with the application.

After the insulation has been completed, your installer will also need to provide a completed Producer statement construction (PS3) Injected Wall Insulation.

The installer should be listed on our producer statement authors register.
