MDF Door Construction

TruStile pioneered the use of medium density fiberboard (MDF) as a preferred material for painted door applications, realizing its many advantages over alternative materials like natural wood. Since we introduced our MDF doors to the market, we’ve seen many impersonators.

What is MDF?

MDF is an engineered wood product made from compressed wood fibers bound together with resin. The durable and homogeneous construction of MDF resists warping, cracking and splitting and outperforms natural wood doors for painted applications.
