THERMAL PERFORMANCE (ATTIC APPLICATIDN)
The stated thermal resistance (R value) IS prOVided by installing rn accordance wIth the manufacturer 5 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
