What Cellulose Insulation Is and Why It Performs in Isabella County
Blown cellulose is manufactured from 80 to 85 percent recycled paper fiber treated with borate compounds for Class 1 fire resistance and pest deterrence. At R-3.8 per inch, cellulose brings a typical Mt. Pleasant attic from R-19 to R-49 with approximately 13 additional inches in a single day. Borate treatment makes cellulose inhospitable to insects and rodents in Isabella County homes. Properly installed cellulose performs at design specifications 50 to 100 years after installation.
Why Cellulose Outperforms Fiberglass Batts in Isabella County Attics
Blown cellulose fills every gap, void, and irregular cavity across the entire attic floor including the eave area where the roof deck meets the top plate — a primary air leakage point in older Mt. Pleasant homes. Fiberglass batts cut to fit between joists leave thermal bridges at every framing member. Cellulose at 1.5 lbs per cubic foot resists convective air currents that reduce the effective R-value of low-density fiberglass on cold Isabella County nights.
