What is considered a key benefit of using plywood in construction?

Plywood is renowned for its consistent strength and stability, which stems from its unique construction. Composed of multiple thin layers or veneers of wood, plywood is glued together with the grain of each layer running in alternating directions. This cross-lamination process significantly enhances its structural integrity and resistance to warping, cracking, and shrinking compared to solid wood. As a result, plywood is highly preferred for many construction applications, including flooring, roofing, and wall sheathing, due to its ability to withstand both load and environmental stress effectively.

The other options do not capture the main advantages of plywood. While it can sometimes be less expensive than solid wood, its pricing can vary based on quality and type. The claim that it is only used for decorative purposes dismisses its vital structural roles in construction. Moreover, all woodworking tasks typically require some tools, making the idea of no tools being needed for installation inaccurate. Thus, consistent strength and stability stands out as a primary benefit of plywood in construction.
