Vapor Barrier
A vapor barrier is a special material used in building construction to prevent moisture from damaging walls, floors, and ceilings. Think of it like a protective shield that keeps water vapor from getting into places where it shouldn't be. It's similar to how a raincoat keeps you dry, but for buildings. Construction workers and contractors install these barriers during building or renovation projects to prevent problems like mold, rot, and reduced insulation effectiveness. You might also see it called a "moisture barrier," "vapor retarder," or "vapor membrane" in job descriptions and resumes.
