The 2019 upgraded City Park Building in Bowling Green, Ohio installed an energy efficient Kingspan KoolDuct system during their new construction. This application contains over 6000 square feet of KoolDuct pre-insulated ductwork. This low embodied carbon duct system offered exceptionally low air leakage and was installed with an R8 insulated value without the need for additional insulation. City Park also paired their system outdoors with KoolDuct fortified Thermaduct to give the high quality, phenolic performance both indoors and out.
