UNDERFLOOR INSULATION

Underfloor Insulation Sections

Mammoth underfloor insulation sections are easy to handle and install because they are self-supporting.



Description

Mammoth™ insulation is an easy and cost effective way to create a warmer, healthier home. Heat loss through an uninsulated floor is estimated at 12-14%* so if you have sufficient crawl space under your floor, adding insulation makes sense. EECA and several local councils offer funding support to assist homeowners with retrofitting underfloor and ceiling insulation into existing homes - Ts&Cs apply.

Description

Mammoth™ polyester underfloor insulation sections are self-supporting medium density pads that squeeze into place between joists without staples or other fixings. Cut to a variety of widths, Mammoth underfloor sections are moisture resistant, high performance option that are safer to install than stapled solutions.

Q&A/FREQUENTLY ASKED QUESTIONS



This is a measure of thermal efficiency - is measures the thermal resistance of the material. The higher the R-Value the better.

Minimum R-Values are specified for underfloor in the building code which for all regions of New Zealand is R1.3.

Yes - and Mammoth Underfloor sections are easier to install than most other forms of underfloor insulation since they are:

  • non-irritant
  • do not need staples or other fixings
  • simply squeeze into position between joists
