                            Why Cellulose?
  •    Cellulose that has been properly installed in your walls will not settle.
  •    Cellulose is non-corrosive to steel, copper and aluminum.
  •    Cellulose will not lose it's energy saving abilities over time.
  •    Cellulose will not rot, decay or mildew, and it does not support fungus or mold growth.

   Thermal Performance of Cellulose

The thermal performance of loose filled cellulose compares favorably to other types of insulation. The thermal conductivity of loose-fill cellulose is approximately 40 mW/(K*m) (an R-value of 3.8 per inch) which is about the same as or slightly better than glass wool or rock wool. This doesn’t represent the whole picture of thermal performance. Other important aspects are how well the building envelope is sealed from air infiltration, convective airflows, and thermal bridging.

Cellulose is very good at fitting around items in walls like pipes and wiring leaving few air pockets that can reduce the overall efficiency of the wall. It also seals walls from air infiltration while providing the density to limit convection. The University of Colorado School of Architecture and Planning did a study that compared two seemingly identical test structures, one with cellulose and the other with fiberglass. The cellulose structure had used 26.4% less energy to heat. It also was shown to tighten the structure more than 30%. Subsequent real world surveys have cellulose performing 20-30% better at reducing energy used for heating than fiberglass.

Cellulose insulation is made from recycled paper that is applied as either loose fill into attics and closed wall cavities or damp-sprayed into open wall cavities. Due to its recycled content and potentially higher energy and acoustic performance, cellulose is an environmentally preferable product.

"11 minutes into the burn the ceiling of the uninsulated house collapsed....10 minutes later the ceiling of the fiberglass house also collapsed. The ceiling of the cellulose house did not collapse until 1 hour and 10 minutes after the burn started."

Cellulose helps keep your home warmer in the winter, cooler in the summer, blocks air infiltration, and saves you money!


Noise Reduction With Cellulose Insulation


Noise reduction is achieved in three ways with cellulose. The first is that cellulose completely fills cavities leaving few air pockets for sound to travel in. The second is the cellulose materials ability to trap air. The significant difference between noise reduction with cellulose and fiberglass is its density. Cellulose is approximately three times denser then fiberglass. This helps deaden the sound through walls and between floor levels.

Cellulose insulation actually helps make homes safer by providing up to 50% better fire resistance than fiberglass. In practical terms, this means that occupants have more time to reach safety in case of fire. Unlike fiberglass, it greatly restricts the amount of oxygen available to support combustion.

Blown-in cellulose is a popular alternative to fiberglass insulation. Cellulose is a natural wood product, and 75 percent of what it's made from is recycled newspaper. Fire-retardant chemical additives give the material a class-1 fire rating, making it a very safe product.

One of the biggest advantages of using cellulose is its performance. In fact, because of its density, it has a higher R-rating than and outperforms many common insulation products. Its loose nature makes it easier to install into irregular spaces, creating a custom-fit monolithic seal over an entire area.

From both health and environmental perspectives, cellulose is considered a "green" product -- more ecologically sound than competing products. It doesn't contain formaldehyde, and cancer warnings are not required on its labeling. Since there are no glass fibers, as with fiberglass insulation, cellulose does not cause itch.

Different insulations are made from fundamentally different materials. Tests at Oak Ridge and Brookhaven National Laboratories and the University of Illinois reveal that insulations with the same laboratory R-values do not perform equally in real homes. Researchers found that the effective R-value of blown fiberglass plunges during cold weather, while the effective R-value of cellulose actually increases. The researchers also discovered that summer temperatures offer no relief for fiberglass, since its effective R-value withers then, too.
