Settled fiberglass in older attics
Why it happens here
Most homes built before 1990 in Orchard North and Orchard East have fiberglass batts that have settled and compressed over decades. The material loses R-value as it compresses, so a 6-inch batt that started at R-19 may now perform at R-10.
Our approach
We measure the actual depth and density, then blow cellulose on top to reach R-49. We do not remove the old batts unless they are wet or contaminated. This is the most cost-effective upgrade for older Pleasant Grove Orchard homes.
