Thanks for the info but I never used a dark material over my darkroom door. I had success using the right weather stripping and a good weather seal for a door bottom. In the end I was scanning the prints to send to the printers of election materials of local politicians. The printers were by then just wanting the scans to make their B&W mailers from and not the prints.
I use it over the windows and door jams in my bathroom. Wonderful stuff.
