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

This product conforms to the performance reqUIrements of ASTM ( 764 Type I and cancelled Federal Spec.ficat,on HH 11030B Type I
Class B R values are determined In accordance w,th (687 and C 51B
* R means res,stance to heat flow The h'gher the R value, the greater the insulating power Ask your seller for the fact sheet on R values
FRAMING ADJUSTMENT
To achieve labeled R value, thiS product must be applied With a pneumatic blow
Ing machine and a corrugated hose With a minimum 25" Internal corrugatIOn, a
minimum length of 150 ft and a diameter of at least 3" COils In the hose should
not be less than 36" In diameter Acceptable matenal feed rate IS 5-35
Ibs {minute Recommended feed rate IS 15 25lbs {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
