What is a Subfloor and Why is It Crucial for Carpet Tile Installation?
A subfloor is defined as the structural layer of flooring that sits directly on top of the floor joists and serves as a base for finished flooring materials like carpet, hardwood, or tile. It provides stability, support, and an even surface for the installation of flooring products, which is particularly crucial for carpet tiles that require a flat and firm foundation to ensure proper adhesion and longevity.
