The future of engineered flooring. SPC is a Stone Plank Composite that is comprised of natural limestone powder, polymers, and stabilizers. This ridged core provides an incredibly stable base for each flooring plank, combined with the high performance integrated acoustic underlay. Hidden beneath the timber look, the high density stone core, provides an extremely resilient and hardware base for any style and look. Our Project Floors SPC is available in a variation of styles and custom planks to give you the freedom to explore any aesthetic you can imagine.
