Insulation is one of the few things far easier to get right while the frame is open. FreshDuct insulates new builds and major renovations end-to-end β roof, walls and subfloor β to NCC and BASIX, so your home performs from the day you move in.
Tell us the stage and weβll call you back to plan it in.


















Once linings and floors go on, insulating properly gets expensive and disruptive. During the build itβs straightforward β which is the moment to get every part of the envelope right: ceiling, walls and subfloor together.
FreshDuct works to the required R-values for your climate zone under the National Construction Code and BASIX, so the home passes and performs. Typically that means around R6.0 in the ceiling and R2.5 in walls and floors, confirmed against your plans.
One team, one coordinated install, one certificate on completion β rather than three trades and gaps between them. The result is a tighter, quieter, cheaper-to-run home from the first day.
| New-build standard | Cheap installers | FreshDuct |
|---|---|---|
| Scope | Ceiling only | Ceiling, walls & subfloor β the whole envelope |
| Compliance | βSheβll be rightβ | Matched to NCC / BASIX R-values for your climate zone |
| Fit | Rushed around trades | Cut and fitted with no gaps or compression |
| Downlights & services | Covered over | Correct clearances around fittings & services |
| Coordination | Left to the builder | One team, scheduled to your build stage |
| Handover | Nothing | Certificate of compliance on completion |
