Pre-insulated ductwork product substitution eliminating field labor demand
#1Kingspan KoolDuct (phenolic foam PIR panel system), Paroc HVAC duct systems, and comparable pre-insulated ductwork products are manufactured on CNC production lines in controlled factory environments, arriving on-site with insulation already integrated into the duct panel. These systems are not experimental — they are specified on commercial office, healthcare, and education projects across the UK, Europe, and increasingly in North American markets. Documented case studies explicitly note the elimination of the field insulation subcontract as a project cost and schedule benefit. The HVAC insulation subcontract on a ductwork-heavy commercial project can represent 30-50% of a mechanical insulator's regional workload.
