So the word PEPLUM is more encompassing and therefore more useful and, well, it just sounds right.

Medium Density Fibreboard (MDF) is a reconstituted wood panel product. It is a dry-processed fibreboard manufactured from wood fibres, as opposed to veneers or particles, and is denser than plywood and particleboard. MDF has an even density throughout and is smooth on both sides. MDF is reconstituted into wood sheets in a variety of widths and lengths.
