That's called a Farday cage and it should be enough to block out your standard EM waves. However, that's kind of useless in my view because only God has the kind of technology necessary to read your thoughts with EM waves.

Tin is neither magnetic nor dense enough to block electromagnetic waves

most store foil is aliminium
