What is SPC Flooring?

Last modified date

SPC Flooring is one of the two types of rigid core vinyl flooring. It is comprised of a more solid or “rigid” core for better durability. Rigid core luxury vinyl is a glueless format with a click locking installation system.

Rigid core luxury vinyl includes two types:

  • Stone Plastic Composite (SPC): Around 60% calcium carbonate (limestone), polyvinyl chloride and plasticizers.
  • Wood Plastic Composite (WPC): polyvinyl chloride, calcium carbonate, plasticizers and wood-like or wood materials such as wood flour

SPC and WPC share a variety of traits, but there are differences between them. Meaning they are suitable for different types of projects.

The content of WPC and SPC is very similar, though SPC consists of a far more portion of calcium carbonate (limestone) than WPC, which is where the “S” in SPC stems from; it is more close to stone material.

In order to better understand the similarities and differences between SPC and WPC, it is helpful to look at the following quantifiable qualities: Look & Style, Durability & Stability, Applications, and Cost.

Look & Style

There is not much difference between SPC and WPC in terms of designs. They resemble wood, stone, ceramic, marble, and unique finishes are easy to produce.  Both SPC and WPC flooring can be made in different size planks.
Durability & Stability Similar to dryback luxury vinyl flooring (LVT), SPC and WPC flooring are comprised of multiple layers of backing that are bonded. However, unlike dryback flooring, both flooring options feature a rigid core and are a harder product.

Because SPC’s core layer is comprised of more limestone, it has a higher density than WPC, and it is thinner overall. This makes it more durable. Its high density offers better resistance from scratches or dents from heavy items placed on top of the flooring.  The floor is also less susceptible to expansion under heat.


Rigid core products including WPC and SPC were originally created for commercial use. Floor imperfections are more easily hidden with SPC or WPC flooring due to their hard core composition.

WPC is more comfortable underfoot thanks to the foaming agent it is typically comprised of. Because of this, WPC is especially better suited for circumstances where patrons are constantly on their feet. The foaming agent in WPC also provides better sound absorption than SPC flooring does, although many manufacturers offer an acoustic backing that can be added to SPC.  Flooring with acoustic backing is great for settings where noise reduction is important.


SPC is a little cheaper and more affordable than WPC. Their installing costs are same because both can be easily installed with their click locking system.

WPC may be more comfortable and quieter underfoot, but SPC has a higher density. Choosing the right product really depends on what your flooring needs are for a particular project.
