Two main types of plywood are ideal for sub-flooring: CDX and Tongue and Groove. However, if you’re doing a DIY project, it’s important to know about and understand what subflooring is. Wooden, structural subfloors are used to support the installation of durable flooring. Today, plywood is the most used subfloor material.

Plywood is an excellent material for subflooring. It’s inexpensive, easy to work with, and does a fantastic job at distributing weight evenly. The choice of plywood for your subfloor material is an important decision. There are a lot of factors to consider, such as cost, thickness, and durability.

Plywood is the industry standard for most subfloor installations (other than tongue & groove products like Advantech). You can lay virtually any flooring over a plywood subfloor, and it’s a relatively inexpensive building material. Still, there are some instances when a different subfloor material may be a better alternative.
