There are many ways to insulate your crawl space ceiling, and in doing this you are separating your crawl space from your living space (ask us why that's important). One way to insulate is to use closed cell spray foam insulation. This is applied by spraying the foam in between the joists directly on the crawl ceiling (which should only be done by a licensed contractor). Once the application is complete, the spray foam hardens, resulting in a high R-value. This is a higher R-value per inch than fiberglass insulation (which we will explain momentarily). Along with being a great insulator, closed-cell spray foam also acts as a great water barrier (preventing moisture from seeping into your floor joists).
Another way to insulate is to use fiberglass batt insulation. This is applied by rolling out the insulation, fitting it between your floor joists, and securing it in place. When combined with air sealing strategies, fiberglass can be a good alternative to spray foam.
Another technique for insulating your crawl space, which slightly varies from the last two methods, is to use the Cleanspace Encapsulation technique. This is different in that it actually brings your crawl space into your home's building envelope (rather than separating the two spaces). This is typically done by insulating the walls of your crawl space and installing a vapor barrier on the floor.
