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.
