Mammoth Multi - Underfloor thermal
insulation is made in New Zealand from 100% lofted, thermally bonded
polyester fibres. It is easy to install as it is friction fitted
between the floor joists and is able to be squeezed to fit tightly under
the floor which maximises thermal performance and removes the risk of
electrocution. As a medium density section product, it will outperform
underfloor blanket when in-situ.
Scope of use
Mammoth Multi - Underfloor medium density polyester insulation is designed to be friction fitted between the floor joists of homes or commercial buildings to maximise thermal performance. It is squeezed to fit tightly under the floor boards and between the joists and does not require staples or strapping - removing the danger of electrocution.
Mammoth Multi - Underfloor insulation:
- reduces draughts coming up from under the floor
- assists in creating a warmer, drier home
- helps reduce heating costs in winter
- is made using fibres from recycled plastic bottles
- is manufactured to last. InsulPro give it a 50 year Warranty*
- is safe and easy to work with - it requires no protective clothing
- is moisture resistant - should it get wet, it will dry & retain thermal performance
- is non toxic and non-irritant - formaldehyde free with no added chemicals
- is manufactured in New Zealand
*subject to correct installation and adequate protection.

Medium Density Polyester Insulation R1.9 - 90mm (Nominal thickness) x 1140mm Mammoth Multi - underfloor sections come in varying widths...
Width (mm) Coverage (sqm)
Present the long edge of the section to the inside of the joist and then fit the body of the section hard up to the floor boards, squeezing the product on both sides of the joist. Mammoth Multi will compress enough to friction fit in the space provided. NB: It does not need to be folded, but can be if required. There must not be any gaps between sections - make sure all joins are firmly butted together. Where cutting is required, Mammoth Multi must be cut no more than 40mm wider than the gap between the floor joists. This will help achieve a snug fit of the product. NB: Mammoth Multi should be cut in a clear, well lit area to required lengths, ie: outside the underfloor area. InsulPro recommends you use a specialised insulation saw such as Bahco and/or a standard Tajima knife with a sharp blade. Where floor joists are spaced 500mm or greater, Mammoth Multi may require additional support to prevent sagging.
Mammoth Multi required no maintenance. Once installed, it will fit to the space and will retain its thermal resistance for 50 years (with correct installation).
Effective insulation helps to limit the amount of energy used to heat homes and other buildings. InsulPro’s commitment to sustainability starts with high quality insulation products. For over a decade InsulPro has been improving product technology and installation techniques to make sure the Mammoth product range delivers excellent results.
The Mammoth range is made from 100% polyester fibre. Polyester is made from a substance called PET, which is what plastic bottles are made from. PET can easily be recycled. InsulPro supports polyester recycling in two ways; using recycled fibre from plastic bottles as part of the Mammoth product range and recycling production off-cuts back into the process. Plastic packaging for the products is also recyclable. Our commitment to our sustainability journey continues - InsulPro is a carboNZero certified organisation and all Mammoth products are Red List Free (Declare programme).
Mammoth helps create a warmer, more healthy living space - enabling a more energy efficient space. This protects our environment by reducing our fossil fuel consumption.
