What Constitutes the Layers of SPC Flooring?

The product is created in layers as follows from the bottom up:

1. Pre-attached underpad layer: This layer is generally made from IXPE or EVA foam pad, which provides better sound absorption and excellent underfoot feeling.

2. SPC layer: This is the dense, waterproof core for the plank made of natural limestone powder, polyvinyl chloride, and stabilizers. It provides rigidity and stability for the plank

3. Vinyl layer: High definition decorative film for the realistic design and look.

4. Wear layer: Wear resistant transparent layer to restore the authentic color and embossing, protecting it from abrasion

5. UV layer: UV ceramic bead top layer to ensure superior stain-resistant and water-proof performance, saving maintenance costs.

The Benefits of Stone Polymer Composite Flooring

  • It’s 100% waterproof. I mean, this is the trademark of both rigid core and WPC vinyl. It’s perfect for business owners, pets and water-prone areas.
  • Perfect for imperfect subfloors. This is the other trademark of rigid core luxury vinyl flooring. All WPC vinyl is great for uneven subfloors, but rigid core is specially designed for these types of situations, engineered to be installed over any existing hard surface, including tile.
  • Ultra-durable. SPC vinyl flooring is the toughest, most durable vinyl flooring option on the market.
  • Realistic wood and stone looks. Seriously, vinyl is changing. Rapidly. The top-end vinyl floors mimic natural materials better than ever before. SPC vinyl is the best of the best, which means the looks are usually incredibly convincing and beautiful.
  • Zero maintenance. All you need is the occasional vacuum and damp mop to keep your floor looking fabulous.
  • Kiss the phthalates goodbye. Many of our SPC flooring options are phthalate-free. Just check the product highlights to be sure.
  • No expansion/contraction. One big worry for traditional wood flooring is expansion and contraction causing shifting or buckling in the floor. Rigid core does not expand or contract, even when moisture is present.
  • Easy, DIY installation. Rigid core luxury vinyl tiles and planks are easy to install yourself with most options interlocking and floating over your existing surface.
  • Sound absorbent. The SPC core of rigid core luxury vinyl flooring helps absorb sound, making it great for second story businesses.
  • Extra warmth. Rigid core is known for providing extra warmth, especially compared to cold ceramic tile.


Structurally, the WPC core contains added foaming agent to increase resilience and comfort. The SPC has no foam added, giving it a stronger, more robust core.

When it comes to scratches, both SPC and WPC are dependent on the wear layer. You’ll find options from 8MIL all the way to 20MIL+. The thicker the wear layer. the better your floor will hold up.

What's the Difference Between Luxury Vinyl Flooring and Stone Polymer Composite Flooring?

Luxury Vinyl Flooring is a new segment in resilient flooring. It has been in the market for about five years and in that time we've seen quality improve and the applications increase. Ultimately, LVF has become an important flooring category because of its versatility – it works in both residential and commercial segments such as retail, hospitality, corporate, healthcare and education.

LVF includes Luxury Vinyl Tile (LVT) or Luxury Vinyl Planks (LVP), Wood Polymer or Polymer Composite (WPC), and Stone Polymer Composite (SPC) flooring.

Wood Polymer Composite Flooring (WPC)

WPC is a Polymer Core that is lighter in weight. It includes air pockets in the core which can create indentations in the product from furniture and heavy objects. It doesn't require acclimation before installing and is not recommended for direct sunlight or sunrooms.

Stone Polymer Composite Flooring (SPC)

SPC stands for Stone Polymer Composite, a limestone core combined with PVC dust and a stabilizer.  As a result, it's denser due to the core being 60-70% limestone with a 30% PVC core fused together.  Often referred to as rigid core, SPC is 10X more impact resistant than WPC.  It's also more stable to sunlight, can be installed in sunrooms, and has better scratch resistance compared to WPC.

The elastic SPC core is finished with a decorative and protective UV film to create a beautiful and strong flooring.
