What is medium-density fiberboard (MDF) made from?

Refined wood fibers, bonded and pressed.

Start playing free

  1. Thin veneers glued with grain crosswise
  2. Refined wood fibers bonded and pressed into panels ✔
  3. Long wood strands laid in layers

Why: MDF is made from refined wood fibers coated with adhesive, formed into a mat and pressed. The thin veneer layers describe plywood and the long strands describe OSB.

Huh, didn't know that: The ANSI A208.2 standard classifies MDF by its properties and sets dimensional tolerances and formaldehyde emission limits.
