Total plank thickness is often misunderstood as a primary metric for flooring quality, but this is a misconception. Total thickness is simply the sum of all the layers—the wear layer, the decorative film, the core, and any attached underlayment or backing. While a thicker plank may offer a more substantial 'feel' underfoot, better acoustic performance, or a larger, more secure locking joint, it does not inherently guarantee durability. The quality of the core material—whether it is a solid vinyl core or a rigid stone-plastic composite (SPC)—is far more important than how many millimeters thick the plank is. A thinner, high-density core can be more stable and resistant to dents than a thicker, lower-density plank. In professional flooring installation, the subfloor preparation is often more critical than the thickness of the plank itself. If you install a very thick plank over a subfloor that is not perfectly level, the locking joints will be placed under excessive stress, leading to failure regardless of the plank's total thickness. Focus on the core’s density and the manufacturer’s installation requirements for flatness rather than choosing a product simply because it has a higher millimeter profile. Quality is determined by how the layers work together, not just the total vertical height of the piece.
