We recently installed Air Krete insulation in to our walls of our home here in Wisconsin. We also will be installing insulation in to our attic, but we are undecided about which product to use. The Airkrete installers had a little left over so they asked if we want to try in out in the attic since the old stuff was all cleaned out. We did try it in a 10 x 10 ft area, 3 inches thick. We see that Airkrete is pretty fragile though. Our plan was to install 3-4 inches of Airkrete so for it to get into the crevices, and then put cellulose or roll cotton insulation over it. This would be a little less expensive. Do you think the Airkrete will hold up if we do it this way? The installers said yes to this. In fact do you think putting Airkrete in the attic is even a good idea period since it is so fragile? Also, does Airkrete really have some level of sound proofing?

If not to my above attic question, what insulation do you suggest? Cellulose, or cotton rolls? Do you know of any healthier cellulose brands? The installers of Airkrete use Champion cellulose from Fond du lac, WI.

By the way Airkrete came out with a new formula to raise the R-value. We are one of the first homes they installed it in.

Thank you for your help,
