Attic insulation settles below R-value over time
Why it happens here
Fiberglass batts lose thickness over the years, especially when they have been walked on or compressed by storage. In Pleasant Grove Village, many attics are 15 to 20 years old and the insulation is well below the R-49 that code requires.
Our approach
We measure the current R-value with a thermal imaging camera and add blown-in cellulose or new batts to bring it up to code. It is a half-day job for most homes and pays for itself in energy savings.
