Concord is a township in Lake County (ZIP 44060, 44077), about 0–5 minutes from our shop at 7401 Ravenna Rd in Concord Township. Established 1822, named for the Battle of Concord in the American Revolutionary War; suburban/exurban Lake County township anchored by University Hospitals’ TriPoint Medical Center area and manufacturers (Avery Dennison, Ranpak, De Nora Tech); this is where Airlock Insulation’s own shop at 7401 Ravenna Rd is located. Airlock Insulation has been dense-packing cellulose into Lake County attics and walls for years, and Concord homes are a regular stop for our crews.
What we see in Concord homes. Mostly built 1970s-1990s (1,503 units in the 1970s, 1,229 in the 1980s, 852 in the early 1990s per census data) — predominantly single-family detached, 3-bedroom suburban homes; reflects Concord’s growth-era suburban development. Houses from that era were typically built with little or no wall insulation and thin, settled attic insulation, so the biggest wins in Concord 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.
