THERMAL PERFORMANCE (ATTIC APPLICATION)
The stated thermal resistance (R.value) is provided by installing in accordance with the manufacturer's instructions,
the required number of bags per 1,000 sq. ft. of net area, at not less than the labeled minimum thickness. failure to
install both the required number of bags and at least the minimum thickness will result in lower insulation R,value.
