What’s Multilayer Flooring?

The success of product innovation is never measured by frequency – rather, it’s measured by impact. The impact of multilayer floors (MLF) can’t be overstated! At its heart, an MLF product is just what it sounds like: a flooring material composed of layers.

“Multilayered flooring, according to the definition by our association, is any plank or tile format hard-surface flooring product made up of multiple layers of different material that are assembled together, provide that the middle layer is a polymer-based material,” explained Harlan Stone, president of the Multilayer Flooring Association and CEO of Halstead International/Metroflor. “This would encompass WPC, composite core, rigid core, engineered LVT and solid core products.”

While the products do possess some similarities like moisture imperviousness, structural stability, and strength, there are some fundamental differences, primarily in the core itself.

WPC stands for Wood Plastic Core or Wood Composite Core. The core is made of wood or bamboo dust mixed with PVC. Unlike laminate’s core board, which swells when exposed to moisture, WPC’s wood plastic core is 100% waterproof and dimensionally stable. WPC is often referred to as the love child of laminate and vinyl; it highlights the best of both materials. Click here to read more about WPC floors.

What’s the Difference Between WPC and Advanced Rigid Core?

These are two very similar materials. The difference comes in the construction: WPC has a layer of vinyl between the core and the decorative layer. Advanced rigid core floors do not.

Both WPC and advanced rigid core floors may also be referred to as IWP, or Impervious Wood Planks. IWP is a less common term but it is used from time to time.


Unlike WPC, composite core does not contain any wood or fibrous materials. Instead, it mixes PVC and other materials with some limestone filler (calcium carbonate). It’s light, tough, and 100% waterproof like WPC.

Solid PVC cores are similar to composite core floors, but with a different ratio of materials. PVC resin is mixed with calcium carbonate to make a very rigid and sturdy core.


Mineral composites are the mountains of MLF floors: stone-based, strong, and inflexible. They’re inorganic, using a stone or cement base instead of plastics or polymers.



The advances in MLF technology have all taken great strides toward solving some of consumers’ most common flooring conundrums. More durable than traditional vinyl, MLF floors are also better at resisting dents and impact damage. Stability goes hand-in-hand with durability for a real one-two punch of quality. MLF floors are great for commercial areas and busy homes; they’re designed to handle heavy foot traffic not only from people, but also from pets! The high level of scratch and impact resistance found in MLF floors like rigid core and WPC makes them a very sound choice for families with bigger dogs. Floors and pets really can get along!

Another great thing about MLF floors? Ease of installation. The rigidity of the core material compensates for many common subfloor imperfections and reduces the amount of subfloor preparation needed prior to installation. Unlike traditional LVT or sheet vinyl, MLF floors don’t transmit subfloor imperfections or unevenness. The core takes care of that for you!

That’s not to say no subfloor care is needed – always check the manufacturer’s specifications prior to installation.

In addition, MLF floors are all waterproof! They’re ideal for all areas of the home, including kitchens, bathrooms, basements, laundry rooms, and other moisture-prone areas.
