Blown in Cellulose Insulation

Blown in cellulose insulation provides excellent r-value ratings. It can be blown in attics or walls. We provide blown in cellulose as well as blown in fiberglass. We will install either if you have a strong opinion one way or another. Consider the following about using blown in cellulose:

• Blown in cellulose settles over time. It will lose r-value and needs to be added to in the future.
• Blown in cellulose insulation is treated with a mold preventer.
• Blown in cellulose insulation is paper. Cellulose is not wool. Ireland makes wool insulation.
• Blown in cellulose is best for the attic or existing walls. It has great properties for filling existing wall cavities. We do not recommend using cellulose to fill the wall cavities of new construction. This process requires the addition of water. Also, most installers fail to install a vapor barrier by stating that “the density of cellulose does not require a vapor barrier.” We disagree. Read our section on vapor barriers.

With product regulations, there are periods throughout the year when blown in fiberglass is not available. A great alternative is blown in cellulose insulation.
