Installing a Vapor Barrier in Chester, VA

The standard vapor barrier that is installed in the crawl space during construction is a flimsy 6-mil liner that is easily torn apart by any service persons, rodents, and pests who crawl on top of it. This ineffective vapor barrier does not get properly sealed around the piers or foundation walls. Moisture from the earth floor rises into the crawl space through these gaps, adding to the relative humidity if the temperature rises.

CleanSpace is a 20-mil thick vapor barrier that completely seals off the home from the earth’s moisture. It is wrapped around the piers and sealed to the foundation walls using a 4” wide vinyl tape. Moisture rising from the ground is not able to penetrate the CleanSpace liner, adding to the total control of relative humidity in the crawl space.
