How much does insulation cost? Ceiling, wall & underfloor?

While the exact cost of retrofit insulation depends on the size and construction of your home (in addition to the insulation material used) these are average retrofit insulation estimates for a typical Australian 120 sq. meter home:

Ceiling insulation: $1600 to $4000
Wall insulation: $2850 to $7000
Floor insulation: $2900 to $3500

Fortunately, the least expensive of these is also the most important: ceiling insulation, which alone will prevent up to 35% of heat loss. So even if you don’t currently have the budget for a full home installation, you can still benefit significantly from ceiling-only insulation.
