Subflooring

Definition

Subflooring is a material, such as plywood, installed on the floor joists of a building or structure, onto which the walls and finished flooring are attached.

Purpose

The purpose of subflooring is to provide a stable, level base for the construction of walls and the installation of finished flooring, ensuring structural integrity and a smooth surface for subsequent layers.

Examples of Use

• Residential homes use plywood subflooring to support hardwood, carpet, or tile flooring.
• Commercial buildings employ subflooring to create a sturdy foundation for heavy foot traffic areas.
• Renovation projects often involve replacing old subflooring to enhance stability and prepare for new flooring installations.

Related Terms

• Floor Joist: Horizontal structural members that support the subfloor.
• Underlayment: A layer of material placed over the subfloor to provide a smooth surface for the finished floor.
• Finish Floor: The top layer of flooring material that is visible and walked on.

Notes

Proper installation of subflooring is crucial for maintaining the overall stability and durability of the floor system, preventing issues like squeaking or uneven surfaces.
