Non-load bearing walls are walls that do not support any weight from the structure above them. Their primary function is to divide spaces within a building, providing privacy and organization. These walls can be made from various materials, such as drywall or lightweight concrete, and can be easily modified or removed without affecting the building's overall stability. Unlike load-bearing walls, which are crucial for the structural integrity of a building, non-load bearing walls can be altered during renovations. This flexibility allows for changes in layout and design, making them popular in both residential and commercial spaces.
