These doors are Marvin Wood Ultimate Inswing French Doors. This project was done several years ago so Marvin may have changed some of their product names since then. Thanks and good luck with your project!

adding a kitchen addition to back patio.of our 1885 home. using Marvin wood ultimate casements and french doors to patio. Did you also choose wood exterior for the exterior french doors? Marvin is not recommending wood exterior for our doors....thanks!

I believe that these doors are wood exterior as the owner wanted to paint them a custom color. If Marvin is not recommending wood for your doors then I would follow their advice, especially if there is no exterior covering outside the doors.
