Vinyl flooring is a product made by layering different materials, including vinyl
The most common type of vinyl floor consist of 4 layers: a felt, fiberglass or vinyl backing; a core layer; a decorative layer with the flooring pattern; and a final “wear layer” on top that protects the flooring from scratches and scuffs.
Vinyl flooring can be installed in any room in the house, including rooms at, above or below grade (ground level). It can also be installed over almost any type of subfloor (concrete, wood, vinyl), as long as the subfloor is smooth and level. If the subfloor has imperfections, they may show through the vinyl.
