WPC consists of a core layer of wood flour, plasticizers, and foaming agents, resulting in a lightweight, cushioned feel underfoot with higher sound absorption. SPC, however, combines limestone powder and stabilizers to create a much denser, thinner core that is nearly impervious to fluctuations in temperature. This makes SPC ideal for rooms with floor-to-ceiling windows where thermal expansion is a risk, while WPC is preferred for residential comfort where long-term standing occurs.

What core attributes define the performance gap between SPC and WPC luxury vinyl cores?
WPC (Wood Plastic Composite) uses a foamed core providing superior comfort and warmth, whereas SPC (Stone Plastic Composite) uses a limestone-based core offering extreme rigidity and dent resistance. The primary gap is in impact resistance and thermal stability under sunlight.
