Ideal applications for COMFORTBATT
®
insulation.
The higher density of ROCKWOOL COMFORTBATT
®
ensures a snug
friction t in the wall cavity. Note: A vapor retarder may be required
in the wall assembly, depending on the geographical location of the
building.

When insulating attics, use two layers of COMFORTBATT
®
to achieve the
required R-value. The bottom layer should run parallel to the joists and the
top layer run in the opposite direction. For attics and cathedral ceilings,
only a single layer of COMFORTBATT
®
is required between the roof trusses.
