Prefinished paneling is a decorative sheet product that is applied as a wall finish. Used in a variety of interior spaces, it may be installed as a wainscot or as a full height wall covering. During the 1960's and 1970's, embossed paneling was popular. Today's prefinished paneling features more modern and contemporary designs. Paneling is manufactured from different types of engineered woods, to varying levels of quality.
