what is sub flooring

Subflooring is the layer of flooring that is directly beneath the visible flooring surface, such as carpet, hardwood, laminate, or tile. It is attached to the homes floor joists and acts as a base for the finished flooring. The subfloor is what creates a stable, level surface to walk on and gives your flooring support. It is typically made of plywood or oriented strand board (OSB) panels. The purpose of a subfloor is to offer a structurally sound flat surface to hold up the underlayment and finish floor. The subfloor provides a stable, level surface that new flooring can be easily installed on. The subfloor is the support used so the final floor covering is properly supported. The subfloor is the middle layer of a flooring system, and it distributes all the weight your floors take from daily activities.
