Make sure your building codes allow this type of crawl space insulation method. Check with your pest control company as well to be sure that insulating the walls of the crawl space does not disturb the pest control in place.

Seal any vents from the foundation. Check anything located in the crawl space, such as a water heater or a heating system and make sure it has sealed combustion.

Check for air leaking into the crawl space from the outside wall and seal any leaks found.

Find any place allowing access to the crawl space from inside the home, and ensure it stays sealed even after many uses. Install an access point like this if one does not already exist.

Purchase batt insulation or a foam board variety that stays rigid and bring it to the crawl space. Locate the band joist and coat it with the batt insulation. Coat the access point into the crawl space with insulation if this point is in a crawl space wall.

Get a termite shield that works continuously and install it in between the foundation and the band joist to prevent infestation. Make sure the shield extends to all of the wall insulation and that it reaches all the way outside the crawl space.

Bring in a supply outlet and install it into the crawl space.
