Oran Park Building
Inspections

The insulation that was never installed

Invisible from the day the plaster goes on.

Owner Inspections · Oran Park 2570 · 2026-02-24

In short: Wall and ceiling insulation absent on Oran Park jobs, found at lock-up.

When it goes in

In the few days between the services being complete and the linings being fixed.

What we recorded

Insulation not installed to walls and ceilings, in more than one area of the same Oran Park house.

Why it matters

The energy rating your house was approved against assumes the specified insulation is present. Without it the house costs more to run and does not perform as approved.

Why nobody catches it later

Once plasterboard is fixed the cavity is closed for the life of the building.

The argument for lock-up

This is the finding that most clearly justifies the stage, and it is the stage owners most often skip.

FAQ

Questions Oran Park owners ask about this

Could thermal imaging find it later?

Sometimes, under the right conditions. It is a far less certain and more expensive route than looking at an open wall.

Is it a defect?

It is a contract and Code compliance question, since the approved rating relies on it. The report records where it is absent.

Who fixes it?

The builder, before lining. After lining it becomes a much larger conversation.

How long is the window?

A few days, which is why the booking has to be timed to the trades rather than the calendar.
