I went searching and found some info.

I find it quite interesting that the best defense we have against EMP is still the Faraday box/cage, a technology developed by Michael Faraday in 1836. The original prototypes made by Michael Faraday used aluminum foil lining the walls of the room. Because of the nature of the dissipation across the surface, it was also found that leaving the windows unsheilded didn't affect the performance of the cage by all that much.

Some common building materials can also act as Faraday cages. Materials such as plaster mesh, woven rebar in concrete and even some of the metallic coated varieties of insulation can provide effective protection against EMP blasts.

Here's a few links with more information regarding Faraday cages and their effectiveness against EMP:

webphysics.davidson.edu... This is a Java applet that demonstrates the effect of a Faraday cage on EM fields.

en.wikipedia.org... Wikipedia's entry on the Faraday cage, also contains a link to Wikipedia's entry on Michael Faraday as well.
