Whether you're building a new home or doing a renovation, Mammoth makes it easy.

The easy, safer option for New Zealand builders Mammoth® polyester insulation creates warmer, healthier homes for New Zealanders and also creates an easier, healthier work environment for builders.

  • It's soft, non-itch and non-toxic.
  • No need for protective gear like gloves, face-masks and overalls.
  • With no gloves required, handling the product is easier.
  • The friendly fibres are heat bonded together so there's no glues or binders.
  • Polyester is not a potential food source so it has no pesticides either.
  • Wall sections and Mammoth Multi for underfloor require no straps or staples (no risk of electrocution).
  • You can maximise thermal performance with a smooth finish without bunching, creases or folds.
  • Your customers will be happier with less toxins in their home and long-lasting effectiveness that carries a 50 year warranty when correctly installed and adequately protected.
  • There's a Mammoth product suitable for every new build or retrofit insulation project.
  • You can order the complete Mammoth range through your local building supplies merchant or to find out more Meet a Mammoth Rep.
