The benefits of cellulose insulation over other types
of insulation are striking. Cellulose has an R-value of
3.8 per inch vs. 2.2 per inch for regular fiberglass batts.
The density of cellulose also makes it a superior sound
barrier - achieving STC ratings as high as 45 in a standard
2x4 wall.
Our method of spraying or injecting cellulose into cavities
at high densities ensures that it achieves a tight air
barrier, without the voids or gaps of conventional insulation.
This air barrier also blocks the flow of moisture, since
airflow accounts for 98% of moisture transfer, ensuring
your home will be free of rot, mold, and condensation-related
problems. The cellulose fibers are impregnated with
naturally occurring fire retardant borates. This makes
cellulose insulation not only safer than fiberglass
and foam, but also safer than almost any other material
in the building. Cellulose insulation provides a 1-hour,
2x4 load-bearing firewall when a single layer of 1/2
inch type X Gypsum is used on each side of the wall
assembly. And our NuWool Wallseal is one of the only
insulations on the market treated to prevent mold. Few
other insulations can make this claim, and only cellulose
insulation provides all these benefits and performance
in one package.
The advantages of cellulose insulation
over fiberglass are dramatic:
- Tests confirm that cellulose provides up to 40%
better thermal and sound performance than fiberglass.
- Cellulose remains effective at blocking heat transfer
at temperatures below freezing, while the effectiveness
of fiberglass drops substantially.
- Cellulose is the only insulation made primarily
from recycled material, making it better for the environment.
- Cellulose processing requires far less energy than
the production of either fiberglass or foam products.
- Spray-applied or dry dense-packed cellulose adheres
to construction joints and edges eliminating gaps
and voids left by traditional fiberglass batt insulation.
