Do red bricks home/building and aluminum insulation diminish the strength of radio signals?


Yes, of course, for some types of "bricks", some ranges of frequencies, and some values of "diminish". Just about everything absorbs or reflects some frequencies accross the radio spectrum.

  • \$\begingroup\$ Depends on the frequency. If you make the Al thin enough you can get some light through it... you can't see through a brick. :^) (I'm talking about very thin Al ~10's of nanometers.) \$\endgroup\$ – George Herold Sep 19 '14 at 14:30

    \$\begingroup\$ @JohnU If you make a brick thin enough to see through, is it still a brick? :) \$\endgroup\$ – JYelton Sep 19 '14 at 17:37
