Upgrading attic insulation is one of the smartest moves you can make for comfort and energy bills. Here's what affects the price, the types of insulation available, and whether the upgrade is worth it.
What drives the price
- Attic size: larger attics need more material and labor.
- Insulation type: fiberglass usually costs less than spray foam.
- Current insulation: removing old material adds cost.
- Labor: rates vary by region and company.
- Access: hard-to-reach attics cost more.
Attic insulation types and costs
| Type | Cost per sq ft | Pros | Cons |
|---|---|---|---|
| Fiberglass batts | $0.50 – $1.50 | Affordable, widely available | Loses effectiveness if compressed or wet |
| Blown-in cellulose | $1.00 – $2.00 | Good coverage, eco-friendly, fills gaps | Settles over time |
| Spray foam | $1.50 – $3.50 | Air sealing, high R-value, long-lasting | Higher upfront cost, pro install |
| Rigid foam board | $2.00 – $4.00 | High R-value, moisture resistant | Costs more, trickier install |
