Insulation questions, answered by experts

The lifespan of crawl space insulation depends on how well you maintain your insulation and the type of insulation. Fiberglass will need replacing every 15 to 20 years on average if you don't have a vapor barrier in place. If you do have vapor barriers in place, then your insulation could last much longer. Spray foam insulation can last anywhere from 80 to 100 years. 

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

Yes, cladding can help insulate your home by adding an additional layer to the exterior walls, which can minimize heat loss and enhance energy efficiency. However, it's essential to select cladding materials that include insulation for optimal results, as cladding without built-in insulation won't make nearly as much of a difference.

Your home's location, budget, and the type of insulation you’re using are just a few of the factors that can help you choose the right insulation. For example, blown-in insulation is typically used in attic spaces, while batts and rolls are ideal for floors and walls. Blown-in insulation is usually a good option if you're adding more insulation to an area that already has some, but not enough.

Cellulose insulation is usually made from recycled paper products, such as old newspapers, but cellulose might also contain recycled denim. While most homeowners traditionally buy cellulose insulation to use for installation, it is possible to make your own at home with old newspapers, cardboard, a paper shredder, and boric acid (important for fireproofing your cellulose insulation materials).
