Stud walls are vertical structures made from wooden or metal frames that support the walls of a building. They are typically covered with materials like drywall or plasterboard, providing a surface for painting or wallpapering. Stud walls are commonly used in both residential and commercial construction due to their lightweight and cost-effective nature. These walls serve several purposes, including providing insulation, soundproofing, and space for electrical wiring and plumbing. The spaces between the studs can be filled with insulation materials to enhance energy efficiency. Overall, stud walls are essential components in modern building design.
