Vapor barrier, while often overlooked as a necessity, is extremely important to the health of your crawlspace and ultimately the health of your entire home. Typically made of polyethylene, the barrier is a thin plastic film that covers the dirt foundation of a home or building from wall to wall.
When installed correctly, vapor barrier acts as a layer of protection, preventing absorption of the ground’s moisture into surrounding wooden structure (your home’s foundation). If unchecked moisture buildup can result in the following:
- Wood Rot
- Overall integrity loss to the surrounding structure
- Development of mold or mildew
- Failing Insulation
- Pest and Rodent Infestations
- Nasty Odors
Many of the problems listed above might catch you by surprise, specifically the issue of failing insulation and pest infestation. Excessive moisture without proper ventilation prevents insulation and other insulating materials from regulating the temperature of enclosed spaces, specifically the attic and crawlspace. In addition to an inability to control the surrounding temperature, insulation exposed to moisture for a prolonged period is predisposed to develop mold and other harmful bacteria.
Pest infestations might also appear to be an unlikely negative side effect of little to no vapor barrier. Heat from the ground causes moisture to vaporize, warming the crawlspace and creating an inviting environment for rats, rodents, and insects. Coupled with the fact that crawlspaces are rarely disturbed by homeowners, rodents and other pests are allowed to run freely in these enclosed areas, spreading droppings and other potentially toxic germs. A vapor barrier prevents the vaporization of moisture, regulating the temperature and thereby deterring any critters from making the crawlspace their home.
