When there are gaps between bricks and other materials, building shims
provide the minor adjustment needed so that everything fits together correctly. They are an indispensable supply for professional builders and contractors, and useful in projects such as framing
and installing insulation
. When installing a new roof or building a deck, shims
also help to make sure wood beams are correctly aligned. When working on exterior jobs, look for shims that are resistant to the elements and suitable for outdoor use.
