Does Crawl Space Insulation Need a Vapor Barrier?

Does Crawl Space Insulation Need a Vapor Barrier

In simplest terms, your crawl space insulation should have a vapor barrier. A vapor barrier can help prevent costly repairs in the future that may be caused by ground moisture.

Without adequate maintenance and care, such as the installation of a vapor barrier, your home’s foundation can sustain significant damage. A vapor barrier is a liner that covers the dirt in your crawl space and blocks moisture from entering.

A vapor barrier is essential to prevent poor-quality air entering your home through the crawl space. Your home contains porous materials such as concrete and wood, and your HVAC system circulates the air. If the air entering your home is poor quality, it can create problems for someone battling a respiratory condition or susceptible to allergies and mold.

In general, porous materials allow air to circulate and moisture to enter your crawl space; by installing a vapor barrier, you minimize that risk. 

Should I Use Faced or Unfaced Insulation in the Crawl Space?

When choosing insulation for your home, faced and unfaced insulation are both suitable, but the differences will help determine which is best for your crawl space. Here are some critical differences between faced and unfaced insulation.

  • Faced Insulation
    • Includes paper vapor barrier—a vapor barrier blocks moisture from reaching the inside of your home, which is useful in humid locations like the Northeast. 
    • Easier to install—Many DIYers tend to use faced insulation because it’s easier to install. The insulation is held together by the vapor barrier, allowing you to roll, move, and staple it without it falling apart. 
    • More expensive – Faced insulation is typically more costly due to the added service of a vapor barrier. 
    • Unfaced Batts
    • Does not have a paper moistur barrier on the backside, potentially allowing moisture and condensation to worp the floor and damage insulation in the long term.
