SPC hybrid flooring

SPC hybrid flooring is hybrid flooring with a core of stone plastic composite. The core is a dense, rigid board made with a large share of limestone powder mixed with plastic. Rigid means hard and stiff. The core sits in the middle of the plank, under the printed design layer and the clear wear layer. Many hybrid floors have an SPC core.

What SPC stands for

SPC usually stands for stone plastic composite. Some suppliers write stone polymer composite or solid polymer core. All these names mean the same kind of core: fine limestone powder held together with plastic and formed into a hard, flat board. Some suppliers write limestone composite core, or use a trade name of their own.

SPC, WPC and rigid core

Rigid core is the general name for floors with a hard, stiff core of plastic composite. SPC floors and WPC floors are both rigid core floors. WPC usually stands for wood plastic composite, and some suppliers write expanded polymer core. A WPC core is a plastic composite full of tiny air bubbles, in some products with wood fibre in the mix. The two cores differ in three main ways.

• Weight. An SPC core is denser, which means heavier and more tightly packed. A WPC core is lighter.
• Thickness. A WPC plank is usually thicker than an SPC plank, because its core takes more space.
• Feel. A WPC plank usually feels softer when you walk on it. An SPC plank feels firmer.

Neither core is the right one for every home. Read which core the product sheet names. Some sheets give only a trade name.

What we found in 111 hybrid ranges

In November 2026 we read the official supplier pages of 111 hybrid ranges.

• On 32 ranges the supplier named the core as SPC.
• On 20 ranges the supplier named it a limestone or stone composite, which is the same kind of core.
• On 2 ranges the supplier named it WPC.
• On the other 57 ranges the pages we read gave a trade name, or no core type.

Of the 54 ranges where the supplier named the core type, 52 named SPC or a limestone or stone composite. So the core type alone often does not tell one range from another.

What makes one SPC floor different from another

For two SPC floors, compare these lines on their product sheets: the total thickness, the wear layer, whether an underlay is attached, the plank size, and the rooms the supplier states the floor is made for. Our guide "What is hybrid flooring?" explains each layer of a plank.

Our guide to hybrid flooring thickness explains the thickness and wear layer lines.

Before an SPC floor is laid

A rigid core can often cope with small flaws in the subfloor, but it does not remove the need for a good one. The subfloor is the floor under your new floor. A hybrid floor is usually a floating floor: its planks click together and are not glued down. It needs a subfloor that is flat, dry and solid. The installation instructions of the floor's maker say how flat it must be and what must go under the planks.
