The main distinction in the comparison between SPC and WPC vinyl flooring comes down to their core layer. SPC has a rigid core made primarily of limestone and stabilizers, which makes it incredibly dense and durable. It’s designed to be tough—able to handle heavy traffic and resist dents from furniture or foot pressure. WPC, on the other hand, has a core made from a combination of wood flour and plastic polymers. This composition gives WPC a slightly softer, more resilient feel underfoot. It’s not quite as rigid as SPC, but it provides better comfort and sound absorption, which can be especially appealing in living spaces or bedrooms where comfort matters more than industrial-level durability.
