Vinyl products are backed with a layer of felt. Cushioned vinyl is backed with a thin layer of foam that offers an extra measure of comfort and safety. In general, a thicker vinyl surface means better quality and higher price. Thicker vinyl can have a textured surface that looks like real stone and wood.
Vinyl flooring has a wear layer on its upper surface that helps resist stains and scratches. The best vinyl products provide warranties on the wear layer of as much as 15 years, and you can expect good-quality vinyl to last 20 years.
