moisture barriers

Moisture barriers are materials installed in buildings to prevent dampness and moisture from passing through walls or floors. They help control humidity and protect structural components, prevent mold growth, and improve indoor air quality. Typically made of plastic or other impermeable materials, these barriers are placed in areas like basements, crawl spaces, or beneath floors. Their primary purpose is to stop water vapor from migrating into insulation, wood, or other building elements, ensuring the space remains dry and reducing potential damage or health issues caused by excess moisture.
