how many bags of green fiber r13-r60 need for 160sq ft and 12"

Hello pedromon and welcome to The Community!  We are glad that you are here.

The GreenFiber Blow-In Natural Fiber Insulation instructions sheet chart shows that 9.7 bags are needed to cover 100 sq ft to achieve an R-Value of R-60.  For 160 sq ft, you would need approximately 16 bags.  Contact your local Home Depot store’s Tool Rental department for information about renting the blowing machine in your area.

Remember to wear proper eye protection and a dust mask when installing insulation.  Best wishes on your project.
