Subfloor: What Is All That About?

Technically speaking, a subfloor is one of the foundational structures of the floor. You may have seen a lot of different types of subfloors in old houses. But what are they, and why do you need them?

Subfloor: What Is All That About?

Subfloors, as I have already mentioned, are one of the building blocks of the floor. It gives durability to the floors and makes it possible for them to carry the weight of the furniture. No one wants to experience the trauma of seeing their weak floor break, unable to carry the weight of the stuff that is placed on them, right?

That is exactly the reason why most of the old houses, even the new ones, have subfloors. Now that you know what subfloors are let us get into the details of how many types of subfloors are there.

Types Of Subfloor: How Many Are There?

Now, here comes the question— how many types of subfloor are there?

Technically speaking, there are around four main types of subfloor based on the material they are made of. They are:

  • Plywood Subfloor
  • Concrete Slab
  • Oriented Strand Board (OSB)
  • High-Performance Panel

Let us take a look at each of them individually. So keep reading this article till the end to learn more on the respective…

1. Plywood Subfloor

One of the most common materials for making subfloor is plywood. You may be surprised to learn that up until the 1980s, plywood was the only material that was used for making subfloors.

Plywood Subfloor

As most of you may know, plywoods are made by layering sheets of wood veneers and binding them together with the help of high-duty adhesives. This process of multiple layering of the wooden veneers gives them durability like none other.

There are different types of plywood for subfloor making. However, all of them provide the same amount of strength and durability. This means that you can have a very strong base and act as an excellent and secure flooring.

2. Concrete Slab

The next on the list of types of subfloor is the Concrete slab. It is, as the name suggests, made of concrete and water. Unlike plywood subfloors, the subfloors made of concrete slabs take a very long time to dry.

Concrete Slab

Most people choose to have this type of subfloor, thinking that it will end all the problems related to moisture susceptibility. However, they are wrong. This is the reason why it’s advised to check before installing the floors above the concrete slab.

Make sure that your concrete slabs are completely dry before installing the finished floors. If this step is skipped, you will have troubles later and probably end up with dampened floors. However, there is absolutely no doubt that you will have a very strong and sturdy floor if you stick to concrete slabs.

While installing floors, make sure that they are made of traditional hardwood. Concrete slabs go well with these kinds of wooden flooring.

3. Oriented Strand Board (OSB)

Another important and extremely popular material for subfloor is the OSB. OSB stands for Oriented Strand Board. This subfloor material got its name because of the way they are made— layering strands of wood.

Oriented Strand Board

The way they are used and installed is very similar to that of installing plywood subfloors. However, they are not the same thing. Plywoods are made by gluing together thin sheets of wood veneers.

On the other hand, OSB is made from wood strands that are rectangular in shape and arranged in a crisscrossed manner with the help of heavy-duty adhesives. As a result, they are much more uniform compared to plywoods. At the same time, they are less expensive too.

4. High-Performance Panel

Last but not least, we have the High-Performance Panels. They are used a lot in buildings these days as they offer similar benefits as OSB and plywoods. One of the important reasons why they are used is because they are moisture resistant.

High-Performance Panel

These panels are stiffer and can hold much more weight than you think. And all this is thanks to the resin technology of the panels. However, they are not the cheapest option that you will find.
