Good afternoon HomeDepotCustomer. Thank you for taking your time and submitting this great review on Inspiration. We do recommend installation on original wood floors that are nailed/stapled to a wood subfloor as long as they are structurally sound, level and fastened or bonded adequately. Also, all flooring must be rolled with a minimum 100-lb roller after installation. Use a hand roller in areas not reached with a 100-lb. roller. Thank you again for submitting the review and for the helpful advise for future readers.We would love to see photos once the installation is complete. If you would like to share your photos, please send them to askshaw@shawinc.com. Thank you again.~clf
