Factors to consider while calculating MDF panelling thickness

  • B. Ceiling panelling: When it comes to ceiling panelling, thinner MDF panels are often used owing to weight concerns. 1/4 inch (6mm) or 3/8 inch (9mm) thicknesses are generally acceptable for this application.
  • C. Wainscoting: Wainscoting refers to panelling laid on the bottom section of walls, often approximately three to four feet in height. For wainscoting, MDF panelling thicknesses of 3/8 inch (9mm) to 1/2 inch (12mm) are often utilized to give both durability and aesthetic appeal.
