Mammoth Wall Insulation
Description

Mammoth wall insulation is made in New Zealand from 100% lofted, thermally bonded polyester fibres. Mammoth wall sections and blanket are designed to be installed into wall cavities to provide thermal insulation. Wall, airlay sections are designed to be friction fitted into the wall cavity which creates a seamless, smooth fit without tucks, creases or gaps.  This supports higher thermal performance across the system.
