When sourcing vinyl flooring, you must prioritize the Wear Layer Thickness, which typically ranges from 0.1mm to 0.7mm; for commercial high-traffic areas, a minimum of 0.5mm (20 mil) is recommended. Additionally, verify the Total Thickness (usually 2mm to 8mm) and the Core Material type, such as SPC (Stone Plastic Composite) for superior stability or WPC (Wood Plastic Composite) for a softer underfoot feel. Ensure the product features a UV Coating to prevent fading and a Fiberglass layer to guarantee dimensional stability.
