The Different Types Of Crawl Space Vapor Barriers

1. Polyethylene Sheets

Polyethylene sheets are the most common type of crawl space vapor barrier. These sheets are made of plastic and are typically 6 mil thickness or greater. The thickness of the sheets ranges from 6 mils to 20 mils. The thicker the sheet, the more durable and long-lasting it will be. Polyethylene sheets are effective at preventing moisture from seeping up into the home and are easy to install.


2. Cross Laminated Vapor Barriers

Cross-laminated vapor barriers are similar to polyethylene sheets, but they are much thicker and more durable. These vapor barriers are made by laminating together multiple layers of polyethylene and polyester film. The result is a tough, tear-resistant vapor barrier that can withstand heavy foot traffic and other wear and tear.

3. Reinforced Vapor Barriers

Reinforced vapor barriers are made of a layer of polyethylene laminated to a layer of woven polypropylene. The reinforcement makes these barriers much stronger than standard polyethylene sheets, making them a good choice for homeowners who may need to access their crawl space frequently. Reinforced vapor barriers are also resistant to punctures and tears, and can withstand heavy foot traffic.

4. Permeable Vapor Barriers

Permeable vapor barriers are made of materials that allow moisture to pass through while preventing water vapor from seeping up into the home. These vapor barriers are typically made of a layer of polypropylene or other breathable material. While permeable vapor barriers are effective at preventing moisture from building up in the crawl space, they are not recommended for areas with high humidity or water infiltration.

Asked Questions

Without a crawl space vapor barrier, moisture from the soil can seep into your home’s structure and cause issues such as mold growth, wood rot, and pest infestations. This can lead to costly repairs and endanger your family’s health.

Yes, a crawl space vapor barrier can help with sound insulation as it blocks out noise from the outside and reduces the amount of sound that can travel through the floor.

As an expert in crawl space vapor barriers, I recommend a thickness of at least 6 mils for optimal protection against moisture. A thicker vapor barrier, such as 10 mils, may be necessary for areas with high humidity or moisture levels
