Frequently Asked Questions about Vapor Barrier vs Encapsulation

What is the difference between a vapor barrier and encapsulation for a crawl space?

A vapor barrier is a plastic liner that covers the dirt floor in crawl spaces and slows down moisture and vapors. It does not create a sealed space like encapsulation does. Encapsulation involves completely sealing the entire crawl space in thicker plastic, providing a functional layer that covers the soil, walls, and floor, and regulates moisture levels.

What are the benefits of using a vapor barrier in a crawl space?

Installing a vapor barrier in a crawl space can lead to improved air quality, decreased mold problems, and savings on monthly energy bills. It also provides a storage area in the crawl space and helps prevent moisture-related issues like water pooling and damage to the houses’ structure and hardwood floors.

What are the advantages of crawl space encapsulation?

Crawl space encapsulation offers several benefits, including preventing wet insulation, moisture in the air, perspiring windows, pest infestations, rust in ductwork, dry rot, soft floors, and mildew/mold growth. It improves air quality, reduces energy bills, prevents pipe bursts, and adds resale value to the home.

Is it necessary to opt for full encapsulation if the crawl space is not used for storage?

Full encapsulation may not be necessary if the crawl space is not used for storage. However, it’s important to consider the overall condition of the crawl space and any potential issues with moisture or insulation. Consulting a professional crawl space company is recommended to get tailored advice based on your specific situation.

Will using a vapor barrier or encapsulation help keep the floor warmer?

Both using a vapor barrier and crawl space encapsulation can contribute to keeping the floor warmer. However, it’s important to discuss your specific needs, including insulating the ceiling of the crawl space, with the professional companies to determine the best solution for your situation.

Why is crawl space encapsulation more expensive than just replacing the vapor barrier?

Crawl space encapsulation involves a more comprehensive process of completely sealing the crawl space and requires the use of thicker plastic. This additional work and materials contribute to the higher cost compared to simply replacing the vapor barrier. The cost of crawl space encapsulation varies depending on factors such as the size of the space and the extent of the encapsulation required.
