What is the primary function of bridging in frame walls?

The primary function of bridging in frame walls is to provide lateral stability. This is achieved by connecting the vertical studs within the wall to help resist lateral forces that may arise from wind or seismic activity. By using bridging, the structural integrity of the wall is enhanced, preventing excessive movement or deformation. It serves to distribute loads more evenly and increases the overall stability of the wall structure, making it essential for maintaining the safety and durability of residential buildings.

While it might be tempting to think of other options like insulation properties, thermal expansion, or aesthetic qualities, those functions are not typically associated with bridging. Insulation properties relate to materials used within the wall assembly rather than structural connections like bridging. Similarly, while framing may influence thermal expansion and aesthetic qualities, those are secondary considerations, focusing more on appearance and temperature management rather than structural stability provided by bridging techniques.
