What In The World Is 'MDF'?


           MDF Sheets

This is another installment in the Continuing Series of "What In The World Is" articles created by Mike, The Home Depot Answer Man, accept no substitutes.

Medium Density Fiberboard is an engineered product made of wood fibers combined with resin and formed into panels under a specific pressure and temperature. The name MDF is derived from the density of the finished product, LDF light density fiberboard, (particle board) MDF medium density fiberboard etc. MDF differs from particle board by the fact that the wood particles are smaller allowing for a denser and stronger board.


MDF was developed in the United States in the early 1960s based on the design of hardboard, a similar product invented by William Mason (Masonite) in 1925. Mason attempted to turn wood chips discarded by lumber mills into affordable insulation, but when he left his equipment unattended one evening, the wood chips were converted into a thin, durable sheetLarge-scale production of MDF began in the 1980s, in both North America and Europe. MDF is denser and heavier than plywood, can be cut and shaped with regular power tools and its smooth surface takes paint very well.

Its use as a building material includes molding and interior doors and cabinets, where its smooth uniform surface makes an attractive finished product. It also makes a good substrate for laminate counter tops. It’s most commonly sold as 3/4 inch 4 x 8 sheets.

    MDF Molding

If you visit the molding aisle at your local Home Depot, you see most of the molding available is MDF. Its easier to form and has a more uniform surface than wood and costs less to buy than solid wood molding.

The next time you visit your local Home Depot lumber department check out the MDF.
