Dependant on the belief that there's genuinely no way I could get that attic House's envelope totally sealed (stick frame x thirty calendar year outdated household x 40 12 months old homeowner = some difficult to reach nooks and crannies), would you advise one particular form spray foam insulation more than the other, or can it be pointless if I am unable to receive the attic envelope sealed 100%? Don't just would be the envelope sealing a consideration, but obviously so is our very hot and humid Houston climate AND the worth you counsel us to strike the rafter boards with foam to lessen thermal bridging.
Thanks for your reaction. It's possible precisely what is puzzling to me, at the least, is definitely the "shiny floor" which not just demonstrates light-weight, but additionally displays heat. The inside of my portable kerosene heater, such as, features a chrome backing which demonstrates the heat through the kerosene burner in the direction of the entrance Substantially like a shiny metallic roof demonstrates warmth in the Solar again into the sky.

I choose problem using this type of line in your posting. Assuming a adequately ventilated and insulated attic House, the space over the attic insulation is "outdoors" Room, shielded from The weather via the roof but nonetheless "outside the house".
I assist using radiant barriers in unconditioned attics with ductwork. That's why I wrote in my report, "Radiant-barrier roof sheathing is effective at lowering attic temperatures.
Your arguments in favor of radiant barriers are consistent with All those of what I contact "spiritual believers." I've little question that almost nothing I generate, and no analysis knowledge, will undermine your religion.
