TruStile MDF Interior 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.

Where to Buy

Hardwood Wedge Edge System

TruStile MDF doors come standard with The Wedge®, our field-proven hardwood edge system. Designed to stand up to daily use, The Wedge provides superior rigidity, stability and screw-holding power.

Built to Your Exact Specifications

Every TruStile door is made to order, each built to the exact style and size you require. TruStile still builds its MDF doors using traditional stile and rail construction, a method usually reserved for wood doors. Our solid MDF doors are never routed or filled with cheap core materials like those of our competitors. Instead, each door is constructed to provide superior, architecturally correct details and an unequaled finishing surface.
