Benefits
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.
