SPC (Stone Plastic Core) includes ground stone powder in its core, making it stronger and more rigid than traditional LVP (luxury vinyl plank). Both are vinyl-based and look similar, but SPC provides superior durability and resistance to denting and warping. As of May 2025, SPC delivers a more solid, premium tactile experience at a higher price point. Kingdom & Co. specifies SPC for high-moisture and high-traffic areas because the stone core technology provides measurable longevity improvements that justify the investment.
