SPC vs. WPC Luxury Vinyl Flooring: Learn the Difference

While searching for the perfect vinyl flooring, you’ve probably come across the terms SPC and WPC. Wanting to learn the differences and compare SPC vs. WPC vinyl? You’re in the right place.

Both options are known for being 100% waterproof. SPC is a newer product with a signature rigid core that is virtually indestructible. WPC has been the gold standard for vinyl flooring and features a waterproof core that’s comfortable as well as functional.

Discover the pros and cons of SPC and WPC, learn how they’re made, and even compare the cost, durability, and comfort.

What is SPC?

Rigid-core luxury vinyl flooring, also known as SPC flooring, is the most durable waterproof vinyl flooring option on the market. It has a similar construction to WPC, but it comes with an ultra-tough core, which is where the name “rigid core” comes from.

So what does SPC stand for? As it turns out, it stands for a couple of terms that are used interchangeably: stone plastic composite or stone polymer composite. The SPC core is what makes this flooring so incredibly durable, maintaining its form even over uneven subfloors.

That means you can install SPC rigid core luxury vinyl flooring on any level, over almost any existing (hard surface) subfloor, and for any amount of traffic.

Layers of Rigid Core Luxury Vinyl Flooring

Rigid Core SPC vinyl flooring layers

Rigid core luxury vinyl planks and tiles are specially manufactured to be ultra-thin, usually measuring no thicker than 6mm.

So what is giving this thin plank such heavy-duty performance? It’s the layered construction. SPC rigid core luxury vinyl flooring is typically composed of four layers, but this can vary between manufacturers. 

Let’s find out what you can expect from SPC layers:

Backing layer: This is the solid foundation of your plank. Often, the backing will also come with a pre-attached underlayment.

SPC core: SPC flooring contains a solid, waterproof core that won’t ripple or swell. This core is ultra-dense with no foaming agents like you’ll find in traditional WPC flooring. It gives you slightly less softness underfoot, but it makes the flooring extra durable.

Printed vinyl layer: This layer features hyper-realistic photo imagery that makes the vinyl look so much like stone and wood.

Wear layer: The wear layer is like the bodyguard of the plank; it protects your floor from wear and tear. SPC flooring often comes with thick wear layer options for heavy-duty protection.

Cons of Rigid Core Luxury Vinyl Flooring

  • Less comfortable than WPC: Manufacturers designed rigid core vinyl to be sturdy, not comfortable. That’s why it’s so popular in commercial environments.
  • Colder than WPC: That stone composite core doesn’t hold a lot of heat, so you’re going to have some chilly floors when it’s cold out.

This flooring is hugely popular amongst homeowners looking for the look of traditional hardwood without the maintenance. Plus, it’s easy to install, making it a dream come true for DIYers.

Pros of WPC Vinyl Flooring

COREtec Plus 5 Waterproof Vinyl Planks

  • Completely waterproof: From both the top and bottom, WPC vinyl is designed to withstand moisture and prevent water damage to your floor.  
  • Comfort: It’s true, you could just get a wood or stone look tile or SPC plank and it would also be waterproof. But those options are hard. Standing on a hard floor all day isn’t great for your joints or feet. WPC is more resilient and much more comfortable.
  • Style: Luxury vinyl can come in those highly sought-after wood-look and stone-look styles that people can’t stop talking about. 
  • DIY installation: If you like doing things on your own, you will love how easy it is to install WPC flooring. Many come with interlocking tongue-and-groove systems that can float over your existing floor.
  • Low-maintenance: With the occasional sweep and mop, you can easily keep your floor looking as good as new.

Cons of WPC Vinyl Flooring

COREtec Plus Enhanced 7" Waterproof Planks

  • More likely to dent: Compared to SPC rigid core vinyl, WPC isn’t quite as durable. That slightly softer core is more comfortable, but it’s also more likely to dent if you drop something heavy.
  • Slightly less affordable: The cost of WPC is just a bit higher than SPC. However, we are starting to see WPC flooring prices drop and become more affordable. Also, it’s still less expensive than solid hardwood with way less maintenance.

What is the difference between SPC and WPC?

COREtec Galaxy Plus 7" Rigid Core Vinyl Planks

So what is the difference between SPC Rigid Core and WPC waterproof vinyl? The answer to that lies in their different cores.

The waterproof core is the star of the show for both WPC flooring and rigid core flooring. A WPC core is made from wood plastic composite and contains an added foaming agent to increase resilience and comfort.

Meanwhile, an SPC core is made from stone plastic composite with no foaming agent, which makes it stiffer, sturdier, and less resilient.

Because SPC is so durable and unbending it’s often used for high-traffic commercial spaces. That rigid core also makes it less susceptible to dents.

So now that you know the basics of SPC and WPC, it’s time for the ultimate comparison of SPC and WPC vinyl.
