The buildup of moisture in a crawl space can cause damage to the wood in your home’s substructure through condensation. Vapor barriers are applied directly to the soil to prevent moisture and ground water from condensing on wood, which can result in wood rot and other moisture-related issues. 

Benefits of Crawl Space Vapor Barriers

  • Impervious to water vapor
  • Backed by a lifetime product warranty 
  • Recommended by the Building Research Advisory Board

Stop moisture before it starts

A vapor barrier is an important part of the protection of wood in crawl spaces. The threats to wood in crawl spaces include destructive wood-decay fungi and non-destructive fungi.

Destructive Wood-Decaying Fungi

Moisture in crawl spaces leads to three basic types of destructive wood-decaying fungi in the wood components of structures. Our vapor barriers help fight:

  • Cubical brown rot

    Occurs when wood is dry-to-wet and wet-to-dry situations. The decayed wood is brittle and very dark giving a charred appearance.

  • White rot

    Infests wood that is exposed to continuous moisture. It's common in poorly vented crawl spaces. The infested wood takes on a bleached appearance, and the wood becomes spongy and fibrous.

  • Wood-conducting rot

    It is a specialized fungus. It can even infest sound, dry wood. The fungi does this using water from a remote source, often may feet or yards away.

Non-destructive fungi

Our vapor barriers also fight non-destructive fungi like surface mildew and molds as well as sap-stain fungi. These species uses the starches and sugars in wood cells for food without damaging the cellulose. Therefore, while the fungi give the wood and unattractive appearance, the wood retains its structural strength.
