In carpentry, what does the term "load-bearing" refer to?

The term "load-bearing" specifically refers to walls or structures that support weight from above. This means that these elements are integral to the structural integrity of a building, as they carry the loads imposed by the roof, floors, and any additional weight from items within the space. Load-bearing walls are designed to transfer these loads down to the foundation, ensuring stability and safety in the construction.

In contrast, elements that allow light to pass through do not contribute to the structural support and therefore are not classified as load-bearing. Non-structural elements used solely for decoration do not serve a role in supporting any weight, and structures designed primarily for insulation focus on energy efficiency rather than load support. Thus, understanding the function of load-bearing walls is crucial in carpentry and building construction, as it helps in ensuring that buildings are safe and capable of handling expected loads.
