Luxury Vinyl Plank in Worthington, OH

Luxury vinyl plank is a layered product, and the layer people ask about is rarely the one that decides how it performs. The wear layer on top governs how it holds up to grit and claws. The core in the middle — rigid SPC, softer WPC, or a flexible glue-down — governs how it feels underfoot, how much subfloor imperfection it hides, and how it behaves when the room's temperature swings.

Waterproof, as manufacturers use it, describes the plank. A waterproof plank will sit in a puddle and be fine. What happens at the seams, at the perimeter and underneath is a question about the installation, not the product, and it is the one worth asking.

Rigid SPC cores are dense and dimensionally stable, which makes them the sensible choice over concrete slabs and in rooms that get hot in the afternoon and cool overnight. They are also the least forgiving of a wavy subfloor, because a rigid plank bridges a dip rather than following it, and a bridged dip becomes a hollow spot you can hear.

Softer cores feel warmer and quieter and hide minor subfloor variation better, at the cost of denting more easily under a heavy point load. On upper floors in older houses around Newark and Granville that trade is often the right one. On a basement slab it usually is not.
