What are its advantages over laminate? The big advantage for WPC over laminate is that it is waterproof and suitable for environments in which laminate shouldn’t normally be used—typically bathrooms and basements that have potential moisture infiltration. In addition, WPC products can be installed in large rooms without an expansion gap every 30 feet, which is a requirement for laminate floors. The vinyl wear layer of WPC provides cushion and comfort and also absorbs the impact sound to make it a quiet floor. WPC is also suitable for large open areas (basements and Main Street commercial areas) because it doesn’t need expansion moldings.
