With a high R-value and excellent at stopping drafts, mold, and moisture, rigid foam insulation is perfect for basement walls and crawl spaces.
Most people don’t think about the crawl space when they're doing their home updates. It's usually hard to access & people may forget to take it into account when thinking about energy efficiency.
Insulating your crawl space is vital to your home's health. It ranges from making it easier for you to breathe, warmer in the winter, and removes nasty dampness - one of the telltale signs that you've got insulation problems. If any of these 3 things show up then you know that your crawl space needs work.
In the old days, fiberglass batts would be placed between the joists in the crawl space. They're cheaper than other insulation materials and much more widely available.
While it does need a lot of upkeep and can house all sorts of problems, cedarwood smells great and looks really good.
Rigid foam is proof that sometimes good, old solutions are best. Unlike fiberglass, it stays in one place instead of absorbing water or holding moisture that will break down the insulation - it also does not allow air to pass through if its joints are sealed with tape.
Rigid insulation is a popular option for crawl space insulation plans. To complete an air-tight sealing process, the rim joists around the foundation need to be sealed.
Walls are sealed with rigid foam and dirt floors coated with a durable, waterproof membrane to reduce moisture levels.
These can go a long way towards improving the state of your home environment. They create clean, dry, and durable floors which means more comfort and cost savings.
