When evaluating vinyl tile flooring, buyers must focus on the Wear Layer Thickness, which typically ranges from 0.3mm to 0.7mm. For high-traffic commercial areas, a wear layer of 0.5mm (20 mil) or higher is essential for durability. Additionally, verify the Core Material type: SPC (Stone Plastic Composite) offers superior indentation resistance and stability, while WPC (Wood Plastic Composite) provides a softer, quieter underfoot feel. Ensure the product features a UV Coating to prevent fading and a Click-Lock system (like Uniclic or Valinge) for adhesive-free installation.
