Underfloor insulation improves energy efficiency

More than 10% of the heat from your home can be lost through the floor. It's so important that all rental properties must have underfloor insulation and EECA has subsidies to encourage homeowners to insulate their subfloors too.

Underfloor insulation can reduce draughts as well as dampness as it can limit moisture from rising into the house from a wet or damp crawl space below. Limiting rising damp will create a warmer, drier room, and that's where a ground moisture barrier can also help. If you already have foil insulation, we can remove and upgrade torn or damaged foil.

The best underfloor insulation.

Some insulation doesn't cope as well with the damp conditions under your home and can sag after a period of time becoming less effective.

  • Self-supporting insulation sections: The best underfloor insulation from our persective - Mammoth self-supporting insulation sections. With high R-values, and excellent thermal performance, Mammoth insulation sections are a superior, long-lasting underfloor insulation product.
  • Insulation Blanket: Say goodbye to chilly floors! Insulation blanket is a more affordable option to combat heat loss, keeping your home cozy and energy-efficient. Insulation blankets for underfloor need fixings of some type to hold them in place - most usually stapling.

Michelle, Whakatane

The sales person knew the information but there was no pressure. The installer was excellent and did a careful and tidy job and was very helpful with explaining the operation.
