What is a Sub-Floor?

When it comes to home construction, there are many terms that can be confusing to homeowners. One of those terms is “subfloor.” In this article, we will explain what a subfloor is and why it is important.

First, it’s important to understand that when you look at the floor of a house, you are seeing the finished flooring material. For example, if you have hardwood floors, the hardwood is what you see. However, what you might not realize is that if your house is not on a concrete slab, there is actually a layer of material underneath the finished flooring.

In a wood-framed house with an elevated floor, the finished flooring material is typically on top of plywood. The plywood is what is known as the subfloor. It is the layer of material that is between the finished flooring and the beams that support the floor. The beams are typically made of two-by-fours or other types of lumber and are spaced out every two feet or so.

The subfloor is important because it serves as a barrier between the finished flooring and the beams. Without it, the floor would be open and exposed, which is not only unsightly but also a safety hazard. The subfloor also helps to distribute the weight of the finished flooring and the people and objects on it more evenly across the beams.

In some cases, a subfloor may need to be replaced. For example, if there is water damage caused by a leaking toilet, the plywood may need to be removed and replaced. This is something that a homeowner should be aware of if their contractor mentions the need to replace the subfloor.

It’s also worth noting that if a house is built on a concrete slab, there is no subfloor. The finished flooring material is laid directly on top of the slab.

In summary, a subfloor is the layer of plywood that is under the finished flooring material in a wood-framed house with an elevated floor. It serves as a barrier between the finished flooring and the beams and helps to distribute the weight of the finished flooring more evenly. If your contractor mentions the need to replace the subfloor, it’s important to understand that they are referring to the plywood layer.
