Dunno if this will work. all of the sheets are connected to the earth thatthe garage stands on and I assume there is a non conductive concrete base?
My understanding of Faraday cages is thatthey must envelope the item(s) to be protected in a highly conductive shell and that the items within must be insulated from that shell. Classic faraday cage experiments use shells made of lattice structures ( ie have holes in them) hence the Cage terminology. In the experiments I've attended the FCs were not grounded.
I do not know to what degree FC's can be scaled up. Certainly quite big examples can be found. Tere are many reports of cars and aircraft receiving direct lightening strikes, and the people within them being completely unharmed....this is due to Faraday Cage effect.
To test try ringing a mobile phone left in the garage cage to see if RF can get in... if it rings OK then EMP will get in too... if it does not ring, you know that a degree of shielding is functioning
Not a conclusive reply, but the best I can do.
Does anyone out there know any better? Please advise

I think I will get a chest freezer and remove the electronics from it, wrap the things I want to protect in bubble wrap and put them in the freezer.
Actually I would also line the interior with bubble wrap too.
If I have read your post right, that should take care of things...
It oughtto work. To test it use the mobile phone test mentioned above.
