   How do you insulate a crawl space floor?

   • Rigid boards may be installed with construction adhesive or mechanical fasteners. You may also choose to lay an insulating mat over the crawl space floor. Use an insulation that resists damage from water (not fiberglass or cellulose). Any one of the rigid board insulations will work, but polyioscyanurate has the best R-value (6 to 7 per inch).
