About Brightr

Whether you're building or renovating, Mammoth polyester insulation is the modern answer to creating your warm, healthy and energy efficient home.

Mammoth insulation is made from 100% polyester, similar to a duvet inner or pillow. It is a safe, soft, non-irritant insulation that is free of glues, binders, formaldehyde and pesticides. Mammoth also uses fibres from recycled plastic bottles and so you'll be able to feel good in your warmer, healthier home knowing that you've reduced the planet's landfills.

There is a full range of insulation products available from Mammoth including thermal insulation for ceilings, walls and underfloor as well as acoustic insulation for better sound control in your home, and more recently, decorative acoustic insulation for commercial buildings such as classrooms and public interior spaces.

You can easily install Mammoth polyester insulation yourself as it requires no protective clothing or face masks when handling it. Alternatively, you can have our Mammoth Install team come to you and quote for doing a full professional installation for you.

We are proud to be supporting New Zealand by creating warmer, healthier homes and buildings as well as investing in research and development.
