Up to 20% of the homes heat and energy can be lost through the underfloor. Poor quality or missing underfloor insulation can also cause uncomfortable draughts to come up through the floor boards. A home needs well fitted underfloor insulation in good condition, in all accessible areas and to be at least R1.4 thickness to trap in the heat and energy. 

Sustainability Trust services include insulation assessment, fix-up, top-up and full install of energy efficient insulation from leading brands such as GreenStuf and Pink Batts. Insulation installations come with a three year workmanship guarantee to NZS:4246 (2016) standards.
