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

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
TIlnlmUm length of 150 ft and a diameter of at least 3" COils In the hose should
not be less than 36" In diameter Acceptable material feed rate IS 5 35

ThiS product conforms to the performance reqUirements of ASTM C 764, Type I, and cancelled Federal SpeCificatIOn HH 11030B, Type I,
Class B R values are determined In accordance With C 687 and C 518
* R means res,stance to heat flow The higher the R value the greater the insulating power Ask your seller for the fact sheet on R values
