Marietta homes, by the numbers
The typical home in Marietta was built in 1954, before modern insulation was standard. More than half of the homes here (56.2%) went up before 1960. Houses that age are where we find empty walls and a few inches of old insulation in the attic, if any. Inside Marietta the housing is older than Washington County as a whole, where the median is 1973.

When was your house built? The Washington County Auditor's website (use its property search) [3] lists the year built for most homes. Look up your address and tell us when you call; the age of the house tells us a lot about what is in the walls and attic.
Climate zone and the attic target
Washington County is in climate zone 4A under both Ohio's residential code [4] and the 2021 model energy code [5]. Either way, the attic advice is the same: ENERGY STAR recommends R-60 in an uninsulated attic and adding R-49 where there are already 3 to 4 inches, for zones 4 and 5 alike [6]. What that means for your attic.
