In the world of interior materials, MDF (Medium Density Fiberboard) is one of the most widely used engineered wood products. From modern furniture to decorative wall panels, MDF provides a balance between cost, performance, and aesthetics—but it’s often misunderstood. In this article, we’ll explore what MDF is, how it’s made, its advantages and limitations, whether it’s waterproof, and how surface films like PET can enhance its performance.
