“We almost bought a $9k heater before calling Pro Insulation. They showed us our ceiling was at R1.5. Spent a third of that on insulation instead - the house now holds temperature overnight.”

Is this your house?
A ceiling under R2.0 is the single biggest leak in a Melbourne home. These are the signs.
- 01
Hot upstairs by 3pm, cold by 7am
A thin ceiling lets the roof space heat the rooms below in summer and drain them in winter. Heating bills drop 25 to 40% in the first winter once it is fixed.
- 02
Batts you can see the joists through
Insulation sitting below the top of a 90 mm joist is usually R1.5 to R2.0. Most homes over 15 years old are there. The current Melbourne target is R6.0.
- 03
The heater runs all evening and the room still feels cold
Warm air rises straight into an uninsulated roof space. About 42% of a home's heat loss is through the ceiling, more than any other single part of the house.
- 04
Dust, pests and 40-year-old batts
Old batts compress, slump and collect decades of dust. We take them out and vacuum the cavity with HEPA extraction before anything new goes in.
What goes in
Knauf Earthwool, R5.0 to R8.0, full coverage over the joists.
The same product and the same install on every job. You pick the R-value, we specify everything else.
- Knauf Earthwool glass wool batts
Four tiers. Same install quality.
Every quote prices all four. Thickness is the installed batt depth; a standard ceiling joist is 90 mm, so every tier sits well above it.
- R5.001Standard210 mm
The VEU baseline and the minimum most quotes stop at. Meets code on a tight budget.
- R6.002Plus275 mm
About 30% better than R5.0. Our minimum recommendation for an existing home, and the fit for low-pitch roofs.
- R7.0Most pickedPerformance330 mm
About 70% better than R5.0. Extra-wide batts over the joists. Our most-picked option.
- R8.004Ultimate350 mm
About 90% better than R5.0. For the coldest Melbourne mornings and the hottest afternoons.
What that means on the day
- Joist spacing measured first, so batts fit without gaps or compression.
- Extra-wide batts at R7.0 and R8.0 run over the joists, which removes the thermal bridge most installs leave.
- Downlights, flues and exhaust fans cut around to the clearance the fitting needs, never buried.
- Photos of every stage and a written R-value certificate at hand-over.

What homeowners say after the install
Why Pro vs the rest
The materials cost about the same. The install changes the result.
Every ceiling installer buys batts from the same handful of makers. What happens in the roof space is where the jobs differ.
