Montville is a township in Geauga (input list said Ashtabula, but verified: no Montville Township exists in Ashtabula County (ZIP 44064), about 28 minutes from our shop at 7401 Ravenna Rd in Concord Township. Rural township in northeastern Geauga County; birthplace of the Cuyahoga River; site of Pioneer Waterland & Dry Fun Park; a former Underground Railroad station still stands at US-6/SR-528. Airlock Insulation has been dense-packing cellulose into Geauga (input list said Ashtabula, but verified: no Montville Township exists in Ashtabula County attics and walls for years, and Montville homes are a regular stop for our crews.
What we see in Montville homes. Mixed-age housing: notable pre-1940 stock (171 units) alongside 1970s (168 units) and 1980s (122 units) construction; predominantly single-family detached homes, few mobile homes. Houses from that era were typically built with little or no wall insulation and thin, settled attic insulation, so the biggest wins in Montville 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.
