Mammoth Multi Underfloor Insulation

SUPPLY AND INSTALL. Mammoth Multi underfloor insulation is a premium polyester insulation blanket for underfloor spaces.  Mammoth is famous for it’s close, friction fitting which provides the highest thermal and draught protection. It is backed by a 50-year product durability warranty. All Sustainability Trust insulation supply and install services also come with a free three-year installation warranty.

About 15% of heat in an uninsulated home is lost due to exposure or inadequate underfloor protection from the elements.

Mammoth Multi is a premium 100% polyester insulation with very high insulation performance and thermal ratings. Polystyrene is a very safe product – fire retardant, allergy-free and safe around children. Mammoth Multi insulation is infamous for it's lengthwise and width-wise spring - perfect for friction-fitting into spaces, creating a snug fit without gaps, tucks or creases. This eliminates cold draughts and maximises thermal protection. It is exceptionally good for wooden floors.

Mammoth Multi is made in New Zealand from recycled plastic bottles and is also recyclable at the end of its life. It comes with a 50-year durability guarantee from the manufacturers. We typically supply and install Mammoth R1.9 underfloor blankets, suitable for any home within Greater Wellington.
