Question:

Which is better for a 2-story house : radiant barrier roof or more attic insulation?

Sorry, I asked this in the maintenance and repair section, but no luck.Which is better to have in a 2-story home? My last 2-story home was always hotter upstairs than down. (Physics...heat rises)

Answer:

the best is more attic isolation so that the heat don't come directly to second floor.
