What is the purpose of a moisture barrier in flooring installation?

The purpose of a moisture barrier in flooring installation is crucial in protecting the flooring material and the subfloor beneath it. A moisture barrier serves to prevent water and vapor from penetrating through to the flooring system, which can lead to various issues such as mold growth, warping, and degradation of both the flooring and the subfloor. In environments where moisture levels are high, such as basements or areas exposed to humidity, a moisture barrier acts as a safeguard, creating a protective layer that inhibits the transfer of moisture. This is particularly important for flooring materials that are sensitive to water or moisture, such as hardwood, laminate, or carpet. By maintaining a dry environment, the integrity and longevity of the flooring installation are ensured, resulting in a more durable and reliable flooring surface.
