WPC cores contain foaming agents that make the planks lighter and more resilient, making them ideal for residential comfort. SPC cores, which utilize limestone powder, are much more rigid and dense. This density allows SPC to perform better in areas with significant temperature swings, such as sunrooms, and provides better protection against heavy rolling loads or furniture indentation. Choosing between them depends on whether your priority is underfoot comfort (WPC) or extreme dimensional stability and impact resistance (SPC).
