Compressed fiberglass batts in older attics
Why it happens here
Homes built before 1980 in Valley South and Valley East were insulated with fiberglass batts that have been walked on, dust-filled, and compressed over decades. Compressed batts lose up to half their R-value, which is why those homes have high winter bills.
Our approach
We remove the old batts, air-seal the attic floor, and blow in cellulose to R-49. That gives you a continuous, full-depth layer that performs the way insulation is supposed to.
