> why are we still covering homes with big chunks of styrofoam
The energy loss through foam depends on the temperature on each side of it. So if you can use a fancy coating to keep the outside of your house cool/hot in the day/night, then the energy losses through the styrofoam are reduced, and eventually your heating/cooling bill is reduced.
