Can this go over a glued down , no pile carpet?

Hello donald and thanks for your inquiry. The Style Selections Rigid Core Luxury Vinyl Plank already has an attached underlayment pad to absorb sound and should never be installed over carpet, ad it will weaken the floor and compromise the locking mechanism, plus, it will also void the manufacturer's product warranty. If installing over concrete, what is required is a 6 mil polyethelyne plastic vapor barrier to be installed over the subfloor to prevent mold/mildew from occurring. We highly suggest reviewing the Installation and Warranty Guides (found in each carton or on the product page of the Lowe's website) prior to installing. Thanks again.
