How Does a Crawl Space Vapor Barrier Work?
A crawl space vapor barrier is a layer of waterproof material that is placed over the soil in a crawl space in order to prevent moisture from entering the space.
The barrier is typically made from a thick plastic material or from a rubberized material that is designed to be resistant to both moisture and temperature changes.
The barrier can also be made from polyethylene sheeting or other materials.
The barrier is sealed around the edges of the space to create an airtight seal.
When the barrier is installed correctly, it creates a barrier between the soil and the air in the crawl space.
This barrier prevents moisture from entering the space and condensing on the floors and walls of the space, which can lead to mold and mildew growth.
It also helps to reduce air infiltration, which can lead to drafts and air leaks that can increase energy bills.
In addition to creating a barrier against moisture, the vapor barrier also helps to protect the structure of the home from damage caused by moisture.
Moisture can lead to rotting wood and corroding metal, which can result in costly repairs or replacements.
By creating a barrier to prevent moisture from entering the crawl space, the structure is better protected.
Finally, a vapor barrier can also help to improve energy efficiency.
Moist air passing through the crawl space carries with it a great deal of heat, which can cause the temperature in the space to be higher than the surrounding area.
By using a vapor barrier, this heat can be trapped in the crawl space, creating a more comfortable living environment.
