Which component does not typically comprise wall construction?

Roof trusses are primarily structural elements used to support the roof of a building. They are integral in providing the framework for the roof, helping to carry the weight of the roofing materials and any additional loads such as snow or wind. While they are critical to the overall structural integrity of a building, they are not part of the wall construction itself.

In contrast, the other options directly relate to the construction of walls. Structural Insulated Panels (SIPs) serve as a complete wall system that includes insulation and sheathing in one unit. Exterior Wall Finishes are the outer layers applied to walls for aesthetics and protection. Wall Coverings refer to the materials applied to the inside of the wall surfaces for finishing purposes. Each of these components plays an essential role in wall construction, while roof trusses are exclusively designed for roof support.
