Hey, there.
I’m looking to build a series of barn doors in custom sizes in a sandwich construction. I’m thinking of using a material such as Medex. It’s a formadehyde free exterior grade material that’s like MDF. I think it comes in a variety of thicknesses. I’m looking to use 1/4 and 1/2 material. The doors will be painted.
Are there any other materials that are more readily available that would be appropriate for this application?
Thanks!

Swing or slide?
Largest?
Smallest?

Swing. The opening is about 7' high x 7' wide". Two doors in that opening. I'm planning on putting two windows in each door.
Thanks.

Gut feeling says MDO. Medex is not structurally rated and I would question the fastener holding capabilities and true drability. MDO has proven itself to be one tough item.
Is the MEDEX goin over a frame or do you intend to use it as the door core? As an overlay it may be just fine.

I plan building a sandwich of (interior to exterior):
1/2" (MDO/Medex)
1/2" insulation
1/4" (MDO/Medex)
1/2" (MDO/Medex trim and framing details)
The edges will have solid blocking as will the area in which the windows will be set.
Total thickness 1 3/4" inches. This will allow me to use a standard deadbolt lockset for security.
I am considering an MDF-type product because of it's flatness and predictability. Would you think a high-grade plywood would work? I'll be priming and painting all surfaces.
Thanks, again.

A painted ply should last longer. The mdf tends to chip easily and once it’s wet, well you know.
I had a similar situation when I had to get my full size van in my not so full size garage.
This is a 9’x 7’ opening with two barn doors made of Merranti, a dense rotary mahogany plywood. Each door is 1 ½ “ thick with a 1” overlap in the centre. They weigh about 120 pounds each
The MEDEX is an exterior rated mdf that handles the water just fine, but I doubt that I'd want to use it this way. It is kind of brittle/chippy and is very heavy by comparison to pother suitable materials. The weight of the door would then call for extra heavy hinges.
Also, in designing the door construction and frame, the type of hiung should be considerd, If a large strap hinge or T-hinge, solid material needs to be provided at locations..
