I've been on a 13 year quest (since I built my shop), for a better door seal for my 2 12x12 overhead doors. I decided to ask the smartest person I know...GTT. Standard astragal is hollow and open on the ends. Water and bugs get in there, then when I open the door, all of the "stuff" runs out and drips on the floor. I even had a frog get trapped in there, and croaked for weeks before he "croaked".
I've always thought that some "closed cell" foam product would be good, but never found anything. Any suggestions? I have 2" thick doors.
