Glasswool batts ($13–$37/sqm in Melbourne) are the most common. Rockwool (better fire resistance), polyester (no irritants), and spray foam (gaps and hard-to-reach areas) are alternatives at different price points.
R-value (thickness)
Higher R-values (R4.0, R5.0) cost more but provide better thermal performance. The right R-value for your Melbourne home depends on your climate zone — higher is better in most Australian conditions.
Old insulation removal
If your Melbourne home has old, damaged, or asbestos-containing insulation, removal ($840–$2,625/sqm) is required before new insulation can be installed. Asbestos removal needs a licensed contractor.
Roof access & difficulty
Easy ceiling access (large manhole, adequate height) keeps costs lower. Tight roof spaces, cathedral ceilings, and complex layouts in Melbourne homes increase labour time.
Government rebates
Federal and state rebate schemes can reduce insulation costs by $400–$1,500+ in Melbourne. Check your state's energy efficiency program — eligibility and amounts change regularly.
Wall & underfloor insulation
Ceiling insulation gives the best return on investment. Adding wall insulation ($19–$52/sqm in Melbourne) requires opening walls and is best done during renovation. Underfloor ($16–$47/sqm) suits homes on stumps.

Frequently Asked Questions
How much does ceiling insulation cost in Melbourne?
Ceiling insulation in Melbourne costs $13–$37/sqm installed, or $42–$105 for a standard 3-bedroom home. Price depends on R-value, product type, and roof access difficulty.
Are there insulation rebates available in Melbourne?
Yes — federal and state energy efficiency schemes offer rebates that can reduce insulation costs by $400–$1,500+ in Melbourne. Check your state government's energy website for current eligibility and amounts.
What R-value do I need for my home?
For most Melbourne homes, R3.5–R5.0 for ceilings and R1.5–R2.5 for walls is recommended. Higher R-values cost more but reduce heating and cooling bills significantly — usually paying for themselves within 3–5 years.
How long does insulation last?
Quality glasswool and polyester batts last 50+ years when properly installed. Loose-fill cellulose may settle over time. If your Melbourne home's insulation was installed before 2010, it's worth having it assessed.
Does insulation help with noise as well as temperature?
Yes — particularly rockwool and heavyweight batts provide good acoustic insulation. If noise reduction is a priority for your Melbourne home, ask for acoustic-rated products.
Should I get ceiling, wall, or underfloor insulation?
Ceiling insulation gives the best ROI for most Melbourne homes — up to 35% of heat is lost through the roof. Wall insulation is best added during renovation. Underfloor suits older homes on stumps with draughty floors.
