This should give you a starting point for speculation:

What would it take to turn my house into a Faraday cage? :)

I know you are joking, but if you really wanted to do that a Faraday cage wouldn't work.

Faraday cages only work for high frequency fields, the frequency in those storms is too low for Faraday cages to work.

Instead you need Mu-Metal - and lots of it, several layers probably.

Trust me in a situation of that order, you must be worried about converting your home into a food and water facility rather than worrying about electronics.
