Owners are benefiting from whole life savings of 20% through reduced construction costs, reduced air leakage and superior R-Value performance than traditional fiberglass. KoolDuct’s board is backed by a 10-year warranty.

Architects are benefiting from space savings and CAD based fabrication. Ductwork can now be easily adapted to radius walls and ceilings. With weight savings of up to 75% structural engineering can many times be greatly reduced or eliminated. Since the ductwork is the insulation it can be placed tightly against walls and ceilings. 

Engineers are benefiting from consistent quality and performance. Our Koolduct is modeled and built with Autodesk’s fabrication suite. Modeled submittals, precise dimensions, reduced installation time all lead to shorted critical paths and less jobsite coordination/ headaches. With sheet metal so many times we see over pressurization during construction resulting in leaking duct sealers and poor product performance. Performance issues that are time consuming and problematic during commissioning. KoolDuct’s average leak rating during balancing is .0007.

Contractors are benefiting from smaller construction crews. Small fast construction crews are a result of less field joints due to joints of duct being 13+’, lighter material, less equipment and tools needed, and superior drawings for install. Less call backs related to insulation failures, leakage and balancing issues. Owners of contracting firms are seeing reduced mod ratings related to muscle strains and cuts often associated with sheet metal.
