How do you insulate a door gap? Backer rods are a form of insulation that you should use when the gaps are too big, and you can’t solve the problem by fixing it with caulk. Make sure to cut the correct size, and place it in the holes carefully, so it doesn’t lose its form. After that, caulk the rest of the gaps.
