The Kingspan KoolDuct® System of pre-insulated ductwork is the most advanced and innovative system of air-distribution ductwork available worldwide. It can reduce air leakage by up to 80%, translating into significant energy savings, reduced heating and cooling loads, smaller plant sizes, and capital cost savings. The Kingspan KoolDuct® System is also incredibly lightweight – up to 75% less than sheet metal ductwork – requiring far less support hangers and install labour.
