It’s a fact that most homes and buildings aren’t adequately insulated. Many older homes for example have no insulation at all in critical wall and ceiling areas. Even in newer homes, the minimum insulation levels required by building codes don’t come close to protecting living or working spaces from temperature extremes or lowering energy bills.
With the exception of blown fiberglass in attics, cellulose is a better choice for walls and ceilings than foam insulation. It offers superior thermal and acoustical performance. It is also much more cost effective to install than spray foam.

While wet-spray cellulose is excellent for attics, it may be problematic in walls because it has the tendency to absorb moisture and deteriorate when saturated. This is especially true in northern climates where it may be cold and damp during the winter and warm and humid during the summer. Moisture in the wall can result in rot or mildew.
With the advent of stabilized cellulose, which contains a small amount of water, this problem has been addressed. Stabilized cellulose, when applied with an air barrier on the interior and exterior of a wall cavity, has been shown to achieve an R-value of about 3.6 to 3.8 per inch. This is comparable to the R-value of fiberglass insulation. This type of cellulose should be used in walls and ceilings with an adequate vapor barrier, as described in the Moisture Control Handbook for the U.S. Department of Energy.
