What is a Subfloor: Understanding the Importance of a Strong Base for Your Flooring

Updated: Feb 8, 2023

A subfloor is the layer of material that is installed on top of the structural floor and serves as a base for the finished flooring material. The purpose of a subfloor is to provide a level and stable surface for the finished flooring, to insulate the room from sound and temperature, and to provide a barrier against moisture.

There are several types of subfloor materials, including plywood, OSB (oriented strand board), and concrete. Plywood subfloors are made by layering thin sheets of wood and gluing them together. This creates a strong, stable platform that is well-suited for use with hardwood or tile flooring. OSB subfloors are similar to plywood, but they are made from smaller pieces of wood that are compressed together. This type of subfloor is typically less expensive than plywood, but it is also less durable and may be prone to warping or swelling.

Concrete subfloors are made from poured concrete that has been allowed to dry and cure. This type of subfloor is strong and durable, but it can be more difficult to install than other types of subfloors. It is also a good choice for homes in areas with high humidity, as it provides a barrier against moisture.

In order to ensure that the subfloor is level and stable, it is important to properly prepare the subfloor before installing the finished flooring. This may involve filling in any low spots or gaps, sanding down high spots, and removing any debris. The subfloor should also be cleaned and allowed to dry completely before the finished flooring is installed.

In addition to providing a stable base for the finished flooring, subfloors also play an important role in insulating the room from sound and temperature. This is especially important in multi-story homes, where sound can easily travel from one floor to another. Subfloors with a higher R-value, which is a measure of insulation performance, are better at reducing sound transmission.

Finally, subfloors provide a barrier against moisture, which can cause damage to the finished flooring and the subfloor itself. This is especially important in homes with basements or crawl spaces, where moisture can easily seep up through the floor. To protect against moisture, subfloors should be sealed or treated with a moisture barrier.

In conclusion, subfloors play a critical role in the stability, comfort, and longevity of a home's flooring. Whether you are installing hardwood, tile, or carpet, it is important to choose the right type of subfloor material and prepare it properly before installing the finished flooring. With the right subfloor, you can enjoy a beautiful, stable, and comfortable floor for years to come.
