FAQs — Insulation Cost in Augusta
How much does insulation cost per square foot?
Insulation costs vary widely: fiberglass batts run $0.30–$1.50 per sq ft installed, blown-in costs $1–$3 per sq ft, and spray foam costs $1–$5 per sq ft depending on type and thickness.
What R-value do I need?
The DOE recommends R-38 to R-60 for attics in most of the US. Walls should be R-13 to R-21. The colder your climate, the higher the R-value you need. Check the EnergyStar map for your zone.
Is spray foam insulation worth the extra cost?
Yes, for air sealing and moisture control. Closed-cell spray foam has the highest R-value per inch (R-6 to R-7) and acts as a vapor barrier, making it ideal for crawl spaces and rim joists.
How long does insulation last?
Fiberglass and cellulose insulation typically last 80–100 years if kept dry. Spray foam can last the lifetime of the building. All insulation degrades if exposed to moisture or pests.
