SPC : Stone Plastic (or Polymer) Composite, is more cost friendly, has increased moisture resistance and fare better in spaces that are not heated or cooled, like three-season rooms.
WPC: Wood Plastic (or Polymer) Composite, is thicker and lighter than the SPC core. It is softer underfoot making it more comfortable to stand or walk on for longer periods of time. Its thickness can give it a warmer feel and works well at absorbing sound.
