Compressed fiberglass batts in older attics
Why it happens here
Most homes built in Pleasant Grove Park before 2000 used fiberglass batts, and batts lose R-value when they are compressed by storage, HVAC work, or pest infestation. After 25 years, many attics are running at half their original rating.
Our approach
We measure the actual depth and condition, then either add blown in insulation on top or remove and replace the batts. We air-seal the attic floor first so the new insulation is not fighting a leak.
