What is rim joist insulation?

Rim joists form the primary structure of the floor and are supported at their ends by the house’s foundation. Rim joists usually look like wooden squares running around the top perimeter of your basement walls. Their main purpose is to support the weight of the floor above them.

Without insulation, the only barrier between the inside of your home and the outdoors is the siding or brick. The rim joist typically spans the perimeter of your house, near ground level, and often includes has various openings for pipes that bring utilities into the home. When rim joists are under-insulated or neglected, especially in older homes, drafts enter through the basement sill plate, draining energy and making the floors cold. By properly insulating and air sealing your basement rim joists, your home will be able to keep heat in and unwanted drafts out.

Our team is eager to address your concerns and answer any questions you may have.
