| 1. |
Multiply attic length times width to
determine total square footage to be installed. |
| 2. |
Measure the distance between joists
to determine correct insulation width for the job (15”
or 23”). |
| 3. |
Choose appropriate insulation product
(R-value and width) for your home insulation project.
(Choose insulation product width to match distance between
joists – 15” to 16” or 23” to
24”.) If joist cavity is full, insulation width
makes no difference because you will install new insultion
across and on top of the joists. |
| 4. |
Divide total square footage to be installed
by square footage per package, then round up to the next
whole number to determine total number of packages required. |
