Which materials are considered types of vapor control?

Vapor control materials are crucial in building construction and renovation as they help manage moisture in structures, preventing issues like mold growth and deterioration. The selected choice of plastic lining and interior paint serves as effective vapor barriers because they inhibit water vapor from passing through walls and ceilings, thus maintaining the integrity of the structure. Plastic sheeting, in particular, is commonly used in basements and crawl spaces to block moisture from the ground. Interior paints with specific formulations can also add a layer of protection against moisture infiltration.

The other materials listed do not primarily function as vapor control. Wood paneling and fiberboard can absorb moisture rather than prevent it, potentially contributing to issues over time. Paint thinner and sealants are used for different purposes, such as cleaning or sealing surfaces, but do not provide effective barriers against vapor. Finally, flooring adhesive and caulking can offer some resistance to moisture but are not as effective as dedicated vapor barriers like plastic lining and specialized interior paints.
