Our rollup door has a flexible rubber seal at the bottom that seems to work if you pull the door down firmly. However, the top and sides don't seal at all. The top actually seems like a freeway for the bugs to come on in. So if you have any ideas on the top, let me know. Randi Sue Smith Curator D.C.
