High performance, self-supporting polyester wall insulation sections.
Mammoth™ Airlay Wall Insulation Sections are self-supporting wall insulation sections that squeeze in between wall cavities for a high-performance friction fit - no staples or strap required. Mammoth Wall Sections provide both thermal and acoustic benefits for homes and buildings.
Mammoth Polyester Wall Sections are semi-rigid insulation designed to be friction fitted into the wall cavity, creating a seamless, smooth fit without tucks, creases or gaps. This supports higher thermal performance. Mammoth Wall Sections are made on New Zealand's only Airlay Insulation plant - accept no substitutes.
100% heat-bonded polyester that won't sag or settle over time.
Self-supporting for a smooth friction fit without creases, folds or tucks.
Moisture resistant - in the event of leaks they continue to perform once dried out.
Red List Free - no glues, resins, formaldehyde or pesticides added.
Non-irritant and non-toxic - no precautions are required for handling the product.
Mammoth Wall Insulation Sections are BRANZ appraised.

3 Mammoth™ has been tested under ASTM D5116. Based on test results for a product with similar nominal weight.
4 All individual VOCs were less than their threshold limit values. Carcinogens and reproductive toxins were not identified as part of the VOCs.
Mammoth Wall Insulation Sections have been tested by BRANZ and is covered by BRANZ Appraisal 797.
What is Airlay Insulation vs Carded Insulation?
Traditional carded polyester insulation layers the fibres whereas the more randomised nature of Airlay insulation means it has structural properties that support higher performance.
Mammoth Wall Sections are produced on Australasia's only Airlay insulation plant with properties that supports superior installation and construction R-values.
Mammoth Ceiling Blanket is produced on our carded insulation plants but Mammoth Wall & Underfloor Sections are produced on an Airlay plant.
What makes Airlay Wall Sections better?
The randomised nature of the polyester fibres in Mammoth's Airlay insulation means it has structural properties that allow it to be self-supporting in walls as well as underfloors.
Airlay insulation can be squeezed into position to create a snug high-performance installation without the creases, folds or gaps that reduce thermal effectiveness.
What testing has been done on Mammoth Airlay Wall Sections?
The nature of insulation produced on the Airlay plant is different to traditional polyester or ﬁbreglass insulation and so was believed to perform exceptionally well in wall and underﬂoor systems. To prove and document the performance of Mammoth Airlay insulation, New Zealand’s leading building research laboratory was commissioned to undertake comprehensive independent insitu testing using heat flux transducers and associated software.
The test results showed that for the tested wall construction systems, featuring Mammoth Airlay insulation, exceeded the R-value of equivalent systems in the BRANZ House Insulation Guide.
