UNDERFLOOR INSULATION

Heat loss through an uninsulated floor is estimated at 12-14% so it there's sufficient crawl space under the floor, adding insulation is relatively easy and a cost effective way to create a warmer, healthier home.

Mammoth® underfloor insulation products are easy to handle and install. Made from 100% polyester fibres, Mammoth does not deteriorate, is moisture resistant and unlike polystyrene insulation, won't affect electrical wiring.

Mammoth has three types of underfloor insulation available in a range of widths to suit the home or building:

Self-supporting underfloor sections - medium density insulation sections that need no staples or straps. Perfect for easy DIY installation.
Underfloor blanket - a stapled in insulation blanket that is a cost-effective option. Recommended for use by experienced builders or insulation installers.
Carpark panel - used for when there are occupied rooms directly above a carpark to reduce thermal heat loss.

The NZ Building code has recently changed to:

replace the existing climate zones from 3 to 6 so new homes can be better designed and built based on the climate they're in, and
increase the minimum R-value of ceiling, underfloor and wall insulation.
