Insulation Terms And Values - Intec FORCE/2 Instruction Manual

THE FORCE/2
Insulation T erms and V alues
The resistance (R) to heat or cold. The higher the R Value, the
R-VALUE:
greater the resistance and the better the insulation factor.
All blown insulation will settle after installation. Your
SETTLEMENT:
FORCE/2 installs near settled density. Consult the chart on the material bag
for coverage and install accordingly.
: Every bag of material comes with a coverage chart
COVERAGE
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
Blowers are measured by Cubic Feet per Minute. A low CFM blower
CFM:
reduces "dust" when blowing insulation into an attic. The FORCE/2 features
the lowest CFM of all insulation blowing machines, minimizing the "dust"
problem. You'll be able to see what you are doing.
Blowers are also rated by Pounds of pressure per Square Inch. A high
PSI:
PSI does a better job of blowing insulation. Your FORCE/2 produces 3.2-4.0
PSI which is the best for blowing insulation.
A pocket of air, or void, created by improper agitation in the
BRIDGING:
hopper. A "bridge" can stop production until cleared. Your FORCE/2 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.
Proper air flow requires one square foot of air
VENTILATION:
movement for every 150 square feet of attic area.
Also known as flapper, rubbers, paddles.
