Do you get dings on your car doors from accidentally banging them against the garage wall? Don’t throw away your left over pipe insulation tubes! Use them as a clever solution for this very problem.
We used pipe insulation that was already cut in half the long way and has a self-seal adhesive on it. Next, fit the pipe insulation around the studs on your garage walls. It should stay put on its own, but for a more permanent solution, you can adhere the pipe insulation to the studs by using the self-sealing adhesive or by pounding in a couple of nails.
