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

FRAMING ADJUSTMENT
To achieve labeled R-value, thiS product must be applied With a pneumatic blow-
ng machine and a corrugated hose With a minimum 25" Internal corrugation, a
nlnlmum length of 150 ft and a diameter of at least 3'~Colls In th'e hose should
not be less than 36" In diameter Acceptable material feed rate IS 5-35
Ibs (minute Recommended feed rate IS 15-25 lbs (minute
To compensate for framing members, the number of bags per 1,000 sq ft of
area to be Insulated should be as shown below
