Spray foam insulation : $1,000 to $2,500
Mineral wool insulation: $600 to $1,200

These ranges include materials and typical labor costs. If you plan to install insulation yourself, you can expect to pay less, but professional installation often delivers better long term results.

What Impacts the Cost of Insulating a 12x12 Room

Several factors can change the final price, even for a small space.

Type of Insulation Material

Different materials come with different price points and performance levels.

Fiberglass is the most affordable and widely used

Spray foam costs more but creates a tight air seal
Mineral wool offers strong soundproofing and fire resistance

Wall vs Ceiling Insulation

If you are insulating just the walls, the cost will be lower. Adding ceiling insulation increases the total price but improves overall efficiency.

Existing Insulation Condition

If old insulation needs to be removed, this adds labor and disposal costs. Clean spaces without existing material are quicker and cheaper to work with.

Accessibility

Open walls or unfinished rooms are easier to insulate. Finished walls may require cutting, patching and repainting, which increases labor costs.

Reduce energy loss and lower utility bills
