Vapor Barrier
A vapor barrier is a special material or layer used in buildings to prevent moisture from moving through walls, floors, or foundations. Think of it like a protective shield that keeps water vapor from damaging a building's structure. It's similar to how a raincoat keeps you dry, but for buildings. Professionals who work with vapor barriers help protect buildings from problems like mold, rot, and structural damage. This term might also be called a "moisture barrier" or "vapor retarder" in job descriptions.
