Mammoth airlay insulation is made in New Zealand from lofted, thermally bonded polyester fibres. It's unique properties arise from the manufacturing process, whereby the fibres are completely randomised rather than the traditional layering.
This provides for differing structural properties of the product, enabling it to support itself within a cavity by simply squeezing the section in place. This seamless fit supports higher thermal performance across the system by retaining nominal thickness and a smooth, seamless finish (without tucks, gaps or creases).
Mammoth airlay, thermal insulation which is suitable for underfloors, walls and ceilings (skillion roof) and is friction fitted between joists/dwangs to create a smooth, seamless fit.
