FIBER GLASS BLOWING INSULATION
BATTS AND BLANKEJS
THERMAL PERFORMANCE (ATTIC APPLICATION)
When Installed In accordance with !he man-
ufacturer's recommendations, Knauf batts
and blankets will provide the full R-value
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
