Depending on your home and where you are installing such insulation, you can seek benefits in both rigid foam and spray foam insulation. Rigid foam boards are usually insulated in basements or crawl spaces because of the durability they bring to provide a thermal break and eliminate drafts. Spray foam insulation also acts as an air sealant, that fills hard to reach places in your attic, crawl space, walls, and more. Both are water resistant and can be trusted in keeping your home comfortable. It all depends on the project at hand and the amount of money you're willing the spend.
