It is called a stucco house.
If the expanded metal mesh that the stucco is trowed onto overlaps correctly the house is nearly opaque to RF. Use Al or Cu screen to support insulation in the roof and tie the walls and roof together and your "hat" is complete.
Do not forget that doors and windows allow electromagnetic energy to pass.
Aluminized mirrors are also good shields. That geek with mirrors on the walls and ceiling was on to something.
Interesting. I didn't realize stucco required metal. I thought it was only cement and ceramic.
If money can't buy happiness, I guess you'll just have to rent it.
