Default Most stable man made board? Opinions please

Question: If making cupboard doors (6' x 3') with a veneered board, what do you think is the most stable.

1. 18mm Block Board
2. 12mm ply
3. 12mm MDF

(all factory veneered in mahogany)

Each will be edged and framed in mahogany to look like the warped solid wood panelled doors they are replacing. It is for a warm house in rainy UK so conditions/humidity variable.

Thanks in advance.

Jim

For doors, the MDF will be the most stable in terms of not warping, and it also holds veneer and glue the best, especially if you are applying an edge veneer. The solid-core material will be the least stable. The veneer-core will be relatively stable, in that if it is flat when you receive it, it will probably remain flat, but it can still warp. These are very large doors. I know it would be ungodly heavy, but I would consider a thicker material choice for something this large.

MDF would be the most stable. That's the one I'd use. Good luck in your choice.
