Steps to DIY install Mammoth Insulation

  1. Choose the right product type for the area you want to insulate. View our Product Range for ceiling, wall and underfloor options. If you need further technical information, click here to view the Mammoth Product datasheets.
  2. Select the appropriate product R-value for your climate zone.
  3. Measure the joist widths to accurately order the correct sized wall and underfloor products. It pays to check all joist spacings as many homes have varying joist widths. Below is a table to help you select the correct size.
  4. Calculate the number of square metres you require for each area you wish to insulate.
  5. Carefully read the installation instructions. Every product pack comes with the installation and fitting instructions. Alternatively, you can download them here. Getting it right matters, so please ensure you carefully read the instructions as they outline all recommended tools, cutting instructions, clearances and any hazards you may come across.
