Crawl Space Insulation and Vapor Barrier


Although your crawl space can be a dirty, damp and bug filled area that you might think twice before entering, there are actually a couple of very important components that cannot be overlooked if you want your home to perform optimally.  

If you do not have insulation in the floor system of your home then you are losing a lot of energy. Older crawl spaces are notorious for having fallen or missing insulation.  Only floor systems where the entire floor is insulated will function properly.  To protect the insulation and structural components from ground moisture a vapor barrier (plastic covering) on the crawl floor is also a necessity.  Without a vapor barrier that covers the crawl space floor 100% you will be leaving crawl space susceptible to structural damage, water damage, and mold.
