Bare studs and dusty block walls make a garage feel unfinished and hard to use. These garage interior walls ideas share 12 smart ways to upgrade your space with better materials, storage and protection.
| Item | Why it works |
|---|---|
| Drywall | Clean finish, fire-rated options |
| Plywood | Tough and easy to fix things to |
| OSB | Budget-friendly and strong |
| Slatwall | Built-in storage system |
| FRP panels | Washable and moisture-resistant |

Should I insulate garage walls?
