Mammoth wall insulation is a soft polyester blanket in roll form - ideal for commercial buildings.

Mammoth® wall insulation is available in two forms: blankets and wall sections. Mammoth wall blankets are rolls of lofted 100% polyester insulation designed to be stapled to the top dwang to fit snugly between wall studs in residential and commercial building projects. They are ideally suited to long unimpeded wall cavities including steel framed walls.

Mammoth wall insulation is made from heat-bonded polyester fibres that are moisture resistant and won't sag or settle over time. See also Mammoth Wall Sections and Mammoth Masonry Wall Sections which are self-supporting for a superior fit.

Mammoth products contain recycled polyester fibres. Mammoth wall blanket insulation uses up to 5,600 recycled plastic bottles per 100sqm*.

Our Take-back Program

Talking about taking product back and making it our client’s problem to get it back to us is one thing, actively putting bins around the country and making it easier for our clients to recycle their offcuts is another.

We don’t believe it is good enough to say, get it back to our factory and we will recycle the product. We believe putting our hand up and sharing that responsibility is a necessity. That’s why we are proud to announce we have started the process of putting Mammoth recycling bins around the country. The first two locations, beyond our factory in Auckland, are Hamilton and Wellington. We encourage all Mammoth Insulation users to bring their clean offcuts back to these locations so we can avoid landfill and create a circular economy by recycling them.
