    Another wonderfully informative post! Question: Any thoughts on whether the kind of insulation in an attic matters if you’re goal is to keep cold a/c air in versus warm air in the winter? Asking for a friend who lives in tropical/hot climates, We’re less worried about heat escaping and more concerned with keeping the A/C alive through the long summer months.

      Dear Tropical Friend,

      Fiber glass and mineral/rock wool are probably better suited for southerly weather than cellulose. The latter has decent insulting value but, because it is made with recycled newspaper, can get compressed and deform in the humid air. That said, the idea of recycled newspaper might be very appealing to any Hemingway scholars that may reside at the house in questions.
