Thatched magic

Makes you wonder about the B&Q type steel frame, steel clad industrial buildings as to whether or not they would offer protection against an EMF blast?

The steel portal frames would certainly provide a good ground/earthing for the structure and with the cladding on all walls and the roof, it would certainly be enclosed. The only issue I guess would be roof lights, windows and doors, but doors are normally either steel doors, or metal roller shutters.

Can't really be any different to a steel container with a connected ground plate/rod being used as a faraday cage?????
