A stud wall is a type of interior wall commonly used in construction. It consists of vertical wooden or metal frames, known as studs, spaced evenly apart. These studs provide structural support and create a framework for attaching wall materials like drywall or plaster. Stud walls are popular because they are lightweight and easy to install. They can be used to divide spaces, create rooms, or support fixtures. Additionally, they allow for insulation and electrical wiring to be added between the studs, enhancing energy efficiency and functionality in buildings.
