is the padding considered underlayment

Thank you for your question. “Underlayment” or “padding” are often used to mean the same thing when talking about laminate flooring installation. If the laminate floor product claims to have an “attached pad” or “attached underlayment”, then you don’t need to buy a separate pad/underlayment. However, when purchasing a laminate floor product without an attached pad/underlayment, then you will need to purchase a separate pad/underlayment that is made specifically for laminate flooring. Do not use a “pad” or “underlayment” that is designated to be used under carpet. Additional information concerning installation, care, and maintenance can be found at the manufacturer's web site: www.swisskronousa.com or by calling customer service at 866-334-9923.
