Insulation Terms and Values
R-VALUE:
The resistance (R) to heat or cold. The higher the R-
Value, the greater the resistance and the better the insulation factor.
SETTLEMENT:
All blown insulation will settle after installation Your
FORCE/1 installs near settled density. Consult the chart on the material
bag for coverage and install accordingly.
COVERAGE
: Every bag of material comes with a coverage chart
detailing R-Value ratings. Average ratings for various materials are:
Cellulose: R = 3.7 per inch
Rockwool: R = 2.6 per inch
Fiberglass: R = 2.2 per inch
CFM:
Blowers are measured by Cubic Feet per Minute. A low CFM
blower reduces “dust” when blowing insulation into an attic. The
FORCE/1 features the lowest CFM of all insulation blowing machines,
minimizing the “dust” problem. You'll be
able to see what you are doing.
PSI:
Blowers are also rated by Pounds of pressure per Square Inch.
A high PSI does a better job of blowing insulation.
Your FORCE/1 produces 2.5-3.0 PSI which is the best for
blowing insulation.
BRIDGING:
A pocket of air, or void, created by improper
agitation in the hopper. A “bridge” can stop production until cleared.
Your FORCE/1 is designed with a non-bridging hopper. However, you
may experience a temporary bridge while using your machine.
Waiting a few seconds will most likely clear a temporary bridge. If not,
unplug your machine and redistribute the material in the hopper.
VENTILATION:
Proper air flow requires one square foot
of air movement for every 150 square feet of attic area.
