“...It is theoretically IMPOSSIBLE for any electromagnetic impulse to pass through any conductive barrier, even the metallic screen wire on the old screen door...”
I’ve taught courses on this stuff...and your theory is correct...but remember that any small holes with conductors (wires, etc) leading into the “protected” space will allow the pulse (or at least selected frequencies of that pulse) to enter and do damage.

At low enough frequencies, screen, even continuous foils will not stop a magnetic field from penetrating. It’s far more complicated than you are claiming.
