To answer your question on how I like them, there are several things I would do differently:
-Do or Don't. In between *****. I should have dug up the 4"x6" PT foundation of the door and poured a concrete footing an apron. The frost pinches the doors so badly that you have to push them hard it starts to twist the doors.
-The offset closure strips work very well to seal the door, but it's a bit of a pain and takes two hands to close.
-Windows are well worth it for the light.
-I should have built a small roof above the doors to keep the weather out. The T111 drains water on top of the doors and when it's windy it drips inside. A small roof would have fixed this.
Overall it was a lot of work for a barn I knew I was going to stuff in a dumpster, but I didn't have much choice at the time and they've worked well.
I would still prefer an overhead door, but hate the look of most of them and it wasn't an option for me due to height. Also, in my new barn, I have sliding doors and I'm not entirely happy with how the frost effects the apron pinching these doors as well.
More than you wanted to know I'm sure.
Good luck.
