Estimating how much insulation is needed
5
3
Divide the total square footage of the space to be insulated
by the square feet covered by one bag of the insulation
you’re using. This should tell you how many packages are
necessary to finish the job.
1
Use an Attic Ruler to measure your attic’s current insulation
depth. Next, subtract that figure from the R-value you want
to achieve. The resulting number will be the R-value you
need to add.

Divide the total square footage of the space to be
insulated by the square feet covered by one package of
the insulation you’re using. This should tell you how many
packages are necessary to finish the job.
2
Measure the distance between studs or joists to determine
the correct width of insulation.

List the R-value you want your finished insulation toprovide.
WALLS + FLOORS/CEILINGS

Find the total square footage of the area you want to
insulate, by multiplying the space’s width by its length.

If insulating an uninsulated attic with batts or rolls, measure
the distance between studs or joists to determine the
appropriate insulation width.
