Underfloor Insulation

Next on the list is the process of wrapping your home in a warm blanket i.e. Underfloor Insulation.

If you’re a landlord,  you’ll be aware that underfloor insulation became compulsory for all rental homes on 1 July 2019. But as the proud owner of a beautiful but drafty old villa, you will want us to fix insulation to the underside of your timber floor too; even if you already have floor foil insulation. We promise you’ll feel it in those power bills. And you won’t know how to contain your happiness after you realise that you’ve got cosy warm feet.

There is a bit of a trick to fixing underfloor insulation correctly but done well underfloor insulation not only helps with the R-value (thermal resistance value), it also reduces draughts coming from floor gaps. The underfloor insulation we use is made from polyester, very much like the pillows and duvet in your bed. It ticks all the boxes: NZ made, recyclable, safe, and highly effective!

For elevated houses, you may want to add a ground moisture barrier under your house.


Trust your underfloor insulation to the experts at Total House.
The team members at Total House are committed to giving you a warmer, drier and more energy-efficient house, so high-quality underfloor insulation is just part of the range of services we offer.
