Do I need a subfloor, and if so, what kind? (Follow-up question: What’s a subfloor?)


Do I Need a Subfloor, and If So, What Kind?

A subfloor is a layer of material that is installed between the joists of a floor and the finished flooring. It provides a smooth, level surface for the flooring to rest on and helps to insulate the floor and reduce noise.

Whether or not you need a subfloor depends on the type of flooring you are installing. Solid hardwood flooring and engineered hardwood flooring always require a subfloor. However, some other types of flooring, such as laminate flooring and vinyl flooring, may not require a subfloor.

If you are installing solid hardwood flooring or engineered hardwood flooring, you will need to install a plywood subfloor. The plywood should be at least 3/4 inch thick and should be tongue-and-grooved to ensure a smooth, level surface.

If you are installing laminate flooring or vinyl flooring, you may not need a subfloor. However, it is always best to check with the manufacturer of the flooring to see their recommendations.

Here are some of the benefits of having a subfloor:

  • Provides a smooth, level surface for the flooring to rest on.

  • Insulates the floor and reduces noise.

  • Helps to prevent moisture damage to the flooring.

  • Provides a barrier between the flooring and the joists, which can help to prevent squeaks and creaks.

Here are some of the different types of subfloors:

  • Plywood: Plywood is a common type of subfloor that is made from multiple layers of wood. It is strong and durable and provides a smooth, level surface for the flooring to rest on.

  • Oriented strand board (OSB): OSB is another common type of subfloor that is made from wood chips. It is less expensive than plywood, but it is not as strong or durable.

  • Concrete: Concrete is a type of subfloor that is used in some cases, such as in basements. It is very strong and durable, but it can be more difficult to install than other types of subfloors.

If you are unsure whether or not you need a subfloor, or what type of subfloor you should use, it is always best to consult with a professional. They can help you to determine the best type of subfloor for your needs and ensure that it is installed properly.
