Dwight Porter, the founder of Porter Insulation Products and Porter Truss Company, has died at the age of 81 after a brief illness.
Porter invented the modern system of insulating poultry houses in 1965. He was known for the innovative technique of installing Tri-ply dropped ceilings and his system became the industry standard in modern poultry houses with the advent of tunnel ventilation in the 1990s.
Porter was preceded in death by his wife, Peggy Pinson Porter; a brother, Storey Porter; and sister, Louise House. He is survived by his sons Keith, Don and Brantley, three daughters-in-law, six grandchildren and numerous friends. The funeral was held on Jan. 2 at First Baptist Church in Jefferson, Ga.
