Default blocking radio waves

When I build my new shack, I was thinking about lining the inside of the

Mostly in the 2 meter range and higher.

Would simple aluminum foil work?

If so what frequency range could I expect it to work in?

If not any suggestions on material? The cheaper the better.

I know there is a term for a room like this but I can not rember it..faraday
chamber?

The shack will be 12 foot by 16 foot, right next to my 60' tower, with HF
and 2m antennas on it. I have no idea how they will interact with such a
building...

Thanks

We had very expensive screened rooms at Racal's Bracknell site when I
worked there a few years ago. They were double-screened with copper
sheet on the inside and outside. We had to use double-screened cables
for some measurements, there was too much leakage from standard coax.
