You have some valid points, but it's Mistaken to dismiss the phenomenon of HVAC units with ductwork located in unconditioned attics. In Texas exactly where I Dwell this is a almost ubiquitous follow. If we place in greater than a certain degree of insulation, it could turn out to be unattainable to make use of the attic for storage, and even to stroll properly for the AC for services.
Handles for windshields have existed for decades. I've finished some exploration with thermal imaging on single pane Home windows and have found differential temperatures of ~18 degrees File up or down from window temperature.
I'm aiming to much better insulate the attic of the 1200 sq foot ranch in upstate Ny. It's eight inch fiberglass batts unfaced. I had been pondering a radiant barrier- sounded like a good idea- but when I'm Listening to you correctly the top financial investment could be additional cellulose - One more six inches? in excess of the existing insulation.
