Settled fiberglass batts in attics
Why it happens here
Fiberglass batts lose thickness over time, especially in attics that see extreme heat. After 10 to 15 years, they may be at half their original R-value. In Estates South, many homes from the early 2000s are due for an upgrade.
Our approach
We blow cellulose over the existing batts to fill gaps and boost R-value to R-49. This is faster and less expensive than a full removal in most cases. We verify the final depth with a measuring stick.
