Here is an insulation reply. It is true, three forms of insulation, conduction, radiation and convection. Look it up, interesting to follow that. Yep that was my major and MS degree.
OK, Radiant blankets stop the heat flow into the attic. On insulation, I like batts because you know what you have, on the truck the batts will be rated at about R 38 the R value is the numerical identity of the resistance to heat flow and this is a bit complex.
With blown in, OK there is so many cubic feet of loose material to blow in, when it is done, you would have to go up in the attic, straddle the stringers on the trusses and measure, I do not think you want to do that. With a flashlight you can see all the blankets side by side and they are hopefully about R 38. Loose insulation will settle so even if 10 inches or so is blown in, it will settle in time. One person was concerned about stepping on it in the attic, well, no way, no insulator will do that because if he does, he will go through the Sheetrock and into the house, straight down. They stand on the stringers. So, we had the Radiant sheets added by Gable Insulators, Mr. Bill Mc Kenzie, a great person, a good installer and we IMMEDIATELY could see the improvement in the home comfort.
Another good feature of batts and radiant is that if you want to do any attic work, vents, wiring, storage, it is much easier to do. Good luck. bbbbbb
