- Remove any objects from the attic that might interfere with the
proper application of the insulation.
- Make sure that any eave or soffit vents are not blocked.
- Place one or more attic rulers in each quadrant of the attic space.
This will help you know when you have achieved the correct depth of
- Load the blowing machine hopper with insulation. The hopper should
be kept nearly full so the insulation flow is smooth and even.
- Hold the hose parallel to the floor with the insulation falling 10'
- 12' away. Begin at the far wall and work toward the center. Always blow in
the direction of the joists. Be careful to step only on floor joists, or
else you might accidentally put your foot through the finished ceiling
- Fill three or four joist cavities by moving the hose to the right
and left. Where possible back away from the work to avoid packing the
insulation. Be sure to get insulation to the top of the walls and low
places. Don't cover eave vents.
- Avoid using your hand as a baffle to direct the insulation as it
exits the hose. Do this only when necessary to avoid packing.
- Keep the hose close to the floor where insulation must go under
obstructions like cross bracing and wiring. Insulation must be blown on both
sides of these kinds of obstructions. If an obstruction has caused a low
spot to occur, fill in the area.
- Check the thickness of the insulation to verify that you have
achieved desired R-Value.
