What is Subflooring and Why is it Important?

Subflooring is a layer of material that is installed on top of the joist system in a home. It provides a smooth, even surface for the finished flooring to be installed on. Subflooring can be made of various materials such as plywood, oriented strand board (OSB), or particleboard. It is typically installed over the joists and secured with nails or screws.

Subflooring serves several purposes:

1. Provides a flat surface for finished flooring: Subflooring creates a smooth, even surface for the finished flooring to be installed on, ensuring that it lies flat and looks good.
2. Supports the finished flooring: Subflooring provides additional support for the finished flooring, helping to distribute the weight of the flooring evenly across the joist system.
3. Helps to reduce noise: Subflooring can help to reduce noise transmission between floors by providing a layer of cushioning between the finished flooring and the joist system.
4. Provides a nailing surface: Subflooring provides a surface for the finished flooring to be nailed or screwed into place, ensuring that it is securely attached to the floor frame.

There are different types of subflooring available, including plywood, OSB, and particleboard. The type of subflooring used will depend on the specific requirements of the project, such as budget, moisture resistance, and durability.
