A return wall in construction is a wall that extends at a significant angle from a main wall, often creating an L-shaped or similar configuration. It's typically about the same height as the main, outer wall and is distinct from a partition or low wall.
Types and Applications of Return Walls
Return walls serve several purposes depending on the building's design and context:
-
Residential Construction: In residential buildings, return walls frequently separate houses, often located where side access gates are found. (Source: Land Development 101) They define property lines and provide privacy.
-
Architectural Design: They are used to create architectural features and define distinct spaces within a building, forming an "L-shape" or other angled extensions. (Source: Quora)
-
HVAC Systems: In some contexts, "return wall" might refer to a wall containing return air pathways for HVAC systems. These pathways facilitate proper air circulation within a building. (Sources: InterNACHI®, Construction Instruction, TAM Tech)
Distinguishing Return Walls from Other Wall Types
It's crucial to distinguish return walls from other wall types:
-
Retaining Walls: Unlike retaining walls, which are primarily designed to hold back soil or other materials, return walls focus on creating architectural features or separating spaces. (Source: Quora)
-
Partition Walls: Return walls are typically taller and more substantial than partition walls, which are primarily used to divide interior spaces.
In summary, the term "return wall" can have slightly different meanings depending on the context, encompassing both architectural and HVAC applications. The core concept remains a wall angled off a primary wall, serving various structural and functional purposes.
