MDF Casing
MDF casing, or medium-density fiberboard, is a popular choice for homeowners because it’s economical. Contractors love MDF casing because it’s easy to work with and install. MDF is engineered wood rather than natural, so the casing comes primed, ready to paint, and without imperfections. This allows you to avoid wood warping worries.
The drawback of engineered wood is that it’s typically not as durable as natural wood, so keep that in mind when making your MDF door casing or window casing selection. If it gets damaged MDF will likely need to be replaced rather than repaired.
