Subfloor thickness code
Plywood thickness plays a crucial role in determining the durability and stability of flooring in both residential and commercial settings. As a versatile and affordable building material, plywood has become increasingly popular due to its inherent strength and ease of installation.
To make well-informed decisions when selecting the appropriate plywood thickness for flooring, it is essential to consider factors such as subfloor type, room usage, and weight load requirements.
According to the Engineered Wood Association (APA), the recommended thickness for plywood used in flooring applications typically ranges from 5/8-inch (15.9 mm) to 3/4-inch (19.1 mm).
Thinner plywood sheets might result in sagging or buckling, especially in areas with heavy foot traffic or where larger loads need to be supported. On the other hand, thicker plywood offers greater resistance to deflection and can more effectively distribute weight across the floor surface.
In addition, it is important to consider the plywood grade as well, which can directly impact the overall performance and stability of the
