Settled fiberglass batts in older attics
Why it happens here
Fiberglass batts settle over time, especially in the older homes near Town Square. What started as R-19 can drop to R-11 or lower after 20 years. The insulation looks present, so homeowners assume it is working. It is not.
Our approach
We measure the actual depth and R-value before we quote. If the batts are settled but dry, we can often blow cellulose over them to bring the attic up to R-49. If they are wet or contaminated, we remove them first.
