Default .010

Yes moisture barrier and .010 is thick for what it is. Stuff at stores is .003 to .006 max. I need 2x that.

This may seem a little bit too DIY, buy I cut a thick lawn and leaf trash bag (or contractor) and attach it with RTV. Since I do not run in rain I can't see any difference.

If you 're not set on absolute original, you could get some of the 3 or 6 mil film, cut it to size, then buy a roll of barrier tape to increase the thickness - essentially using the film as a backer to the tape.

This one is 4 inches wide x 180 feet long, you could do each door 10 or 20 times with it.

This is from a random search (no testimony) but I bet it'd work just fine...
