Laminate flooring is a multi-layer synthetic flooring product fused together with a lamination process. Laminate flooring simulates wood with a photographic applique layer under a clear protective layer. The inner core layer is usually composed of melamine resin and fiber board materials. 

Sheet vinyl flooring is vinyl flooring that comes in large, continuous, flexible sheets. A vinyl sheet     floor is completely impermeable to water, unlike vinyl floor tile, which comes in stiff tiles, and vinyl planks, which come in interlocking strips.

Laminate flooring is similar to luxury vinyl planks in its look and installation, but the critical difference is that the surface is a hard plastic laminate with printed design layer, while the core layer is rigid fiberboard, a product made from wood byproducts bonded together with melamine resins. Vinyl flooring is 100 percent synthetic material. In standard sheet vinyl and vinyl tiles, the base layer is usually fiberglass which is then coated in PVC vinyl and a plasticizer. The resulting sheet is printed and embossed with a surface print layer. Over this, one or more wear layers is applied, often a tough layer of "no-wax" polyurethane. Sheet vinyl is known as "cushioned vinyl" features a closed-foam lower layer.
