Dorset is a township in Ashtabula County (ZIP 44032), about 55 minutes from our shop at 7401 Ravenna Rd in Concord Township. Rural eastern Ashtabula County township founded in 1828 (originally named Millsford), renamed for Dorset, Vermont, home of an early settler; centered on the unincorporated community of Dorset with no incorporated municipalities. Airlock Insulation has been dense-packing cellulose into Ashtabula County attics and walls for years, and Dorset homes are a regular stop for our crews.
What we see in Dorset homes. Sparse rural housing stock typical of far-eastern Ashtabula County farm townships; specific construction-era data unknown, but age (founded 1828) suggests a mix of older farmhouses and newer rural homes. Houses from that era were typically built with little or no wall insulation and thin, settled attic insulation, so the biggest wins in Dorset are usually a dense-pack wall injection, air sealing the attic floor, and bringing the attic up to R-49 or better with blown-in Nu-Wool cellulose.
