Roof & ceiling insulation
Loft blown into the ceiling space, settling into an even layer around joists and framing rather than leaving the edge gaps cut batts tend to leave. See blown ceiling insulation.
Floor insulation
Warmafloor blown into the subfloor of a suspended timber floor, and into mid-floors in two-storey homes. See blown underfloor insulation.
New build insulation
Trufill blown into walls, roofs, floors and mid-floors during construction. See new build insulation.

Insulating in Manawatū

Why insulation performs differently in Manawatū

Palmerston North and the Manawatū sit in H1 climate zone 3, a step colder than Whanganui in zone 2. The region is exposed and windy, and an evenly filled cavity does more here than the mild average temperature suggests. Blown loosefill fills the cavity evenly and gets into the awkward places batts leave open, which is where most of the heat actually goes.

New builds, Building Code H1

Palmerston North and the Manawatū sit in H1 climate zone 3, a step colder than Whanganui in zone 2. The region is exposed and windy, and an evenly filled cavity does more here than the mild average temperature suggests.

H1/AS1 moved to its sixth edition on 27 November 2025 and the schedule method was removed, so required R-values now come from the calculation method rather than a fixed table. Read the R-value guide or use the insulation calculators to work out what your build needs.

Rentals, Healthy Homes standard

Manawatū is in Healthy Homes zone 1 and 2. Every rental property must meet these minimums above and below all living spaces.

Walls are not covered by the standard, and in an uninsulated older home they are where most heat is lost. See retrofit wall insulation.
