Insulating a metal garage adds $1,000–$5,000 to the total cost depending on size and material. Insulation improves temperature control, reduces noise, and prevents condensation. Garage buyers in hot or cold climates often find this upgrade essential, especially for workspaces or vehicle storage during extreme weather.
- Fiberglass insulation cost: Fiberglass rolls cost $0.50–$1 per square foot and offer moderate thermal performance.
- Spray foam insulation pricing: Spray foam provides superior sealing but costs $1–$3 per square foot.
- Benefits in humid areas: Insulation prevents moisture buildup, mold growth, and rust in tropical or humid regions.
- Energy savings: Insulated garages help reduce heating and cooling bills, especially for attached garages.
- Soundproofing advantages: Insulation also dampens outside noise, making garages suitable for workshops or home studios.
