Mammoth modern insulation is manufactured by InsulPro — a New Zealand owned and operated manufacturer of polyester thermal and acoustic insulation, supplying local and export markets with a range of insulation products for the home or commercial buildings.

There are Mammoth manufacturing facilities in Auckland and Milton, near Dunedin, and are backed by a team of experts. Mammoth is produced on New Zealand's only air-lay polyester insulation plant. This produces self-supporting thermal insulation sections that can be installed in walls and underfloor without mechanical fixings, and have a smooth crease-free surface to improve thermal performance.

Mammoth Insulation is also the distributor of the Martini dECO range of decorative acoustic solutions including acoustic wall linings, panels and boards.
