Attention
Always use the appropriate
safety and personal protective
equipment when using this
product. These instructions
are only a summary guide
for installing Blown-in Wall
Systems. Installation should
not be attempted without the
appropriate training. Refer to
the product package and product
Material Safety Data Sheet for
additional safety information.
The process of blowing insulation
into walls is best accomplished
with two people. The process can
be broken down into two steps:
1. Installing fabric and
2. Installing wool.
Installing Fabric
1. Use a polypropylene
non-woven fabric for this
application.
2. Fabric comes in rolls. The rolls
contain a 9' wide sheet that is
folded over to achieve a 4½'
roll. The sheet is about 611'
long.
3. Choose a wall section. Unroll
the fabric along the wall
section. Pick up the folded
edge of the fabric and staple
about half way up the  rst stud
in the wall. Take the roll end
of the fabric and staple half
way up the last section of the
wall. Use a razor knife to cut
the fabric to length down the
last stud. Wear safety glasses
with side shields while stapling.
Stapling can cause injury.
Follow all stapling device safety
requirements.
4. Place an appropriately rated
stepladder at one end of the
wall. Standing on the ladder
reach down and lift the outer
 ap of the fabric and staple to
the top plate of the wall. Staple
along the top plate of the wall
over to the other end. Staples
should be placed no more than
1" apart
5. Move to the center of the
wall and staple down the stud
about half way. Moving away
from the center, staple down
adjoining studs half way down.
As you move out from the
center, pull the fabric outward
to remove wrinkles.
6. Move to lower portion of the
wall and staple the rest of the
way down the studs pulling the
fabric as needed to remove
wrinkles.
7. Staple around all windows
and doors. Staple bottom
plate last.
8. Move to the next wall section.
9. If the wall section is taller than
9' you will need to make up
the distance with additional
fabric. The additional fabric will
need to overlap the previously
installed sheet by at lest 6".
The overlap can be taped to
prevent wool from escaping.
Installing Attic Expanding
Blow-In Insulation
1. Use Owens Corning
™
AttiCat
®
Expanding Blown-In Insulation
for this application.
2. Use the AttiCat
®
Expanding
Blown-In Insulation Machine.
3. Use the 2½" hose that comes
with the AttiCat
®
Expanding
Blown-In Machine.
4. With the fabric in place, choose
a stud cavity to start with.
Cut two x patterns into fabric,
one 30" from the bottom and
the other 24" from the top,
large enough to accommodate
the hose diameter. Insert the
hose into the bottom cut and
begin  lling. When the loose ll
stops  owing aim the hose
down then up to compact
the wall cavity. When there
is no additional  ow, move to
the top opening and repeat.
To get higher densities it may
be necessary to cut three x
patterns in the fabric. Fill each
one starting at the bottom
and moving up. When the wall
is full, turn off the AttiCat
®
machine and remove the hose.
5. Inspect the cavity for un lled
areas. These areas can be
seen as lighter colored areas
behind the fabric. Insert the
hose in this area and turn on
