The main differences are that Wood Plastic Composites are waterproof and can go over most subfloors without much preparation. Traditional vinyl floors are flexible and any unevenness in the subfloor will transfer through the surface. Compared to traditional glue-down LVT or solid-locking LVT, WPC waterproof flooring products have a distinct advantage because the rigid core hides subfloor imperfections. In addition, the rigid core allows for longer and wider formats. With WPC, it is not necessary to worry about the preparation LVT would require for use over cracks and dips in concrete or wooden subfloors.
