The full plank-style fiberglass door has always sat somewhere between traditional and contemporary design for me.
On one hand, the strong vertical flow of the plank pattern works beautifully with pull bar hardware, which is usually associated with modern-style doors. On the other hand, the simplicity of the design feels rooted in classic wood door construction. If this were a real wood door, it would be built by joining large vertical planks together—hence the name.
That balance is what makes this style so interesting. It can work on a more traditional home, but with the right hardware and finish, it can also feel clean, modern, and architectural.
Replicating Wood with Fiberglass
This door is another great example of how far fiberglass door manufacturing has come in replicating real wood aesthetics.
Of course, there are no actual wood planks here. The plank effect is created through grooves routed into the surface using a CNC machine. Because the fiberglass skin is extra deep, and because the CNC bit has a V-shaped end, the grooves create a shadow and depth that look very similar to a real plank-built wood door.
There are even different plank width options available, so the final look can be adjusted depending on whether you want a narrower, more detailed pattern or a wider, cleaner one.
Different manufacturers also offer this style in different woodgrain textures to imitate various wood species. This particular door uses a cherry texture, which gives it a warm and rich appearance while keeping the durability benefits of fiberglass.
Why 42 Inches by 8 Feet Works So Well
I really like the proportions of a 42-inch wide door at 8 feet tall. That ratio creates a seriously impressive entry system without feeling too bulky.
This size also happens to work well in many common builder openings. A lot of older double door systems with a small transom above can be replaced with one large single door and sidelights. It modernizes the look while keeping the opening balanced.
Funny enough, I have the exact same builder-style double door and transom setup at my own place, so I already know what size door I’ll eventually replace it with.
Until then, I suppose I’ll remain the classic shoemaker without shoes.
But one day, it’ll happen.
