Understanding Stick and Panel Options

When it comes to choosing stile and rail doors, a lot of time and effort will go into choosing the perfect panel layout, wood type and stain color. Let’s explore an aspect of the door that is not often discussed but plays a pivotal role in both stability and aesthetics: Wood skin thickness.


In the context of what we are speaking to here, stability is resistance to the natural movement of wood in response to changes in environment, primarily humidity. Wood, being a hygroscopic material, expands and contracts with fluctuations in moisture levels. The thickness of the wood directly influences the extent of this movement.

Rule of thumb:

thinner the wood = more stable (i.e. less movement)

There is little aesthetic change with skin thickness for certain wood types. Generally the prime, non-rustic woods will show little to no difference if the thickness is reduced. Knotty, rustic wood are best to keep as thick as possible to enhance the depth of the wood’s knots and natural beauty.

Different wood species also react differently to changes in humidity. In simple terms, certain wood types are more stable than others. White Oak, for example, will have more movement to environmental changes than Alder will.

You could deep dive into the scientific study of wood movement and check out further information on Equilibrium Moisture Content (EMC) tables and the Dimensional Change Coefficients by respective wood types. Or, feel free to use the quick look guides found throughout the Treely Doors™ website showing stability rankings for each wood type offered:

Throughout the United States there are vast differences in climate conditions, which is key to remember when choosing the best wood for your interior doors. Depending on the location, certain wood species and thicknesses are going to be better choices both for the structural stability of the door and for their aesthetic qualities.

We are always here to help, if you have specific questions based on your geographic location we are more than happy to speak with you and discuss your unique project challenges.
