Electricians can't help you here... this is serious business.
First, don't use the aluminum sheeting, it is too permeable and all frequencies still penetrate it. In fact, it sometimes draws signals to it as a conductor and you would become a transmitter relay station.
Now... get yourself a hockey helmet, make sure it's comfortable. Then wrap it in metal lined wall insultation. That'll do the trick.
Run a thin stereo speaker wire from the helmet to the sole of your shoe, that way it's more ergonomic. It'll ground you much like the tires ground your car.
Then, I recommend you post some photos of the outfit to the internet, to make sure you share this important information with others, and me... be sure to email a photo to me.
