Are you referring to Biparting sliding barn doors?
They don't seal well.
I have 16 ft x 16 ft doors on my pole barn. Would really like to retrofit it to an overhead door.

Thanks for the answer. I would like to keep the looks of the pole barn doors. What is the gap between the sliding door and the wall?

Barn is old, and posts are not plumb. Door hangs 2 to 3 inches out at bottom to inch at top. I clamp em tight to posts in winter time. Bolt em together at meeting rail for winter as well. They get a lot of wind pressure, esp when OH Door at opposite end is open.

I'm in Georgia. I'd hate to know that rodents find a way to use the barn with no rent. I might need to have both rollup and classic barn doors. Thanks anyway.

I adopted a feral cat a few years ago. Keeps the rodents away. Also kills rattlesnakes. Only problem is, I am a cat owner.
