Attic Protector is formaldehyde-free fiber glass blown-in insulation that is ideal for attics. The coverage of each bag is determined by the thickness (R-value) blown. Can be applied to any R-value with available fiber glass blown in machine.

Based on the data page (https://www.jm.com/content/dam/jm/global/en/insulation-systems/products/assets/technical-guide/bid-356-attic-protector-attic-card-b-785.pdf), JM shows the installed R-values. R-19 would be the closest to the 7inches you want at ~8inches. Coverage per bag is 109.3sqft. Total bags for 2,200sqft is 21 bags.
You will need just under 16 bags based on this coverage chart: https://www.jm.com/content/dam/jm/global/en/insulation-systems/products/assets/technical-guide/bid-356-attic-protector-attic-card-b-785.pdf 1050/66.5=15.79
Please refer to the attic card: https://www.jm.com/content/dam/jm/global/en/insulation-systems/products/assets/technical-guide/bid-356-attic-protector-attic-card-b-785.pdf Each bag for an R-28 covers 51sqft. For 1800sq ft you need 35 bags... 1800/51 = 35.2
Per our coverage chart, to reach an R-38 you need 15.3" thickness. Each bag covers 51sqft for R-38, so to cover 1,050 sqft you are looking at 20.5 bags. https://www.jm.com/content/dam/jm/global/en/insulation-systems/products/assets/technical-guide/bid-356-attic-protector-attic-card-b-785.pdf
Johns Manville recommends calling Owens Corning to determine this. There might be differences in the insulation as compared to the Attic Protector that JM is unaware of as that is not our product.
https://www.jm.com/content/dam/jm/global/en/building-insulation/Files/BI%20Toolbox/BID-356-Attic-Protector-Attic-Card-B-785.pdf You will need about 68 bags.
Yes, you can use Attic Protector in the walls. JM does not have a "wall chart" so you can use the Climate Pro Wall Coverage Chart and be reasonably close in achieving the same R-value. The main difference would be adjusting for bag count b/c Attic Protector is a lighter weight bag than Climate Pro.
