Applegate Insulation was established in 1978 by Aaron Applegate and his son Terry. They began producing insulation out of a small facility in Okemos, Michigan. Today, Applegate (headquartered in Webberville, Michigan) is the largest privately owned cellulose insulation manufacturer in the world, and supplies a variety of high performance insulation products from seven locations throughout the United States. Applegate launched Cotton Armor in 2011 in order to rectify many issues of yesteryear's batt technology. Cotton Armor blankets are easier to properly size and install than batts and in a life cycle analysis demonstrated a radical improvement in resource utilization by being 54% more energy efficient in production than fiberglass manufacturing.
