/3 3.0 & 4.0 DP

A Glossary

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:

Insulation will settle after being blown. The

FORCE/3 blows 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/3 features the lowest CFM of all insulation blowing

machines, minimizing the “dust”.

PSI:

Blowers are also rated by Pounds of force per Square Inch.

A high PSI does a better job of blowing insulation, the The F/3 3.0

produce 3.0 PSI while the F/3 4.0 DP produces a PSI of 4.0.

BRIDGING:

A pocket of air, or void, created by improper

agitation in the hopper. A “bridge” can stop production until

cleared. The FORCE/3 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 airflow requires one square foot of air

movement for every 150 square feet of attic area.
