Installation and Warranty Instructions for 5-Year Residential and 1-Year Commercial SPC Flooring
For SPC flooring products that come with built-in underlayment, it is not recommended to use any additional underlayment during installation. Using other underlayment products may compromise the performance of the built-in underlayment and void the product warranty. If additional cushioning or sound-dampening is desired, it is recommended to choose a product that does not have built-in underlayment and to use a separate underlayment that is specifically designed for use with SPC flooring. Any use of unapproved underlayment products may result in damage to the flooring and will void the product warranty.
