Absolutely. A thinner cork roll offers a simple, low-profile way to shield your walls from everyday bumps and scrapes. It works especially well behind chairs, headboards, or desks—anywhere the wall tends to get knocked around.
If you're hoping to turn the surface into a message board, though, you'll want something thicker—ideally 5 to 10 mm. Slim cork isn’t sturdy enough to hold pushpins securely on its own. Adding a backing board, such as MDF or fiberboard, is a smart move in that case.
