Kingspan KoolDuct® is a complete HVAC ducting system that offers superior performance in industrial, commercial and residential installations. The Kingspan KoolDuct® System is an advanced and innovative system of pre-insulated air-distribution ductwork. Ductwork is fabricated using premium performance rigid insulation panels in sections up to 13’ long and can provide the optimum energy saving and environmental solution in comparison with other types of ductwork. Premium performance Kingspan KoolDuct® panels, fabrication methods, jointing systems and a complete line of accessories produce a system where air leakage can be reduced to a fraction of that typical of sheet metal ductwork. This can yield significant energy consumption savings because of reduced heating and cooling loads. Maybe that is why the USGBC World Headquarters in Washington DC chose KoolDuct® as it ductwork of choice for LEEDS Platinum achievement.

The Kingspan KoolDuct® System is designed for use in Building Services / HVAC applications and is suitable for both new build and refurbishment projects in the residential, commercial, institutional, industrial, and leisure sectors. Ductwork fabricated from the Kingspan KoolDuct® System is particularly suitable for use on high specification projects in the food, beverage and pharmaceutical industries, clean air and hygiene controlled environments, high humidity environments, swimming pools, and sterile areas of hospitals and communication / server rooms in data centers where non-fibrous insulation materials may be preferred.

Kingspan KoolDuct® System ductwork can be installed internally, externally, concealed above a false ceiling or visibly mounted. Furthermore, its versatility enables individual system components such as plenums, risers and straight sections to be integrated with traditional sheet metal ductwork.

The Kingspan KoolDuct System has many benefits that make it the ideal air distribution system for your project. Below are just some of the features you'll get when you use The Kingspan KoolDuct System.

Air Leakage  The air leakage rate of Kingspan KoolDuct® System ductwork can be a fraction of that of insulated sheet metal ductwork and can easily meet the requirements of SMACNA Class 3. Less air leakage equates to significant energy savings in both fan horsepower and heating and cooling energy.

Zero Ozone Depletion  Kingspan KoolDuct® panels are CFC/HCFC-free and are manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP). By employing better methods to manufacturer and fabricate…we can reduce our carbon footprint to make a better environment for the future.


Moisture Resistance  The insulation core of Kingspan KoolDuct® panels has 90% (or greater) closed cell structure, which means that they are non-wicking and highly resistant to moisture penetration. In addition, the risk of moisture absorption into the core is effectively eliminated as the factory applied aluminum foil facings provide a high performance and impervious vapor barrier. The panels have a water vapor transmission of 0.34 grains/hr•ft²


Indoor Air Quality  Distributed air flows over sealed aluminum surfaces, minimizing any risk of loose fibers entering the air handling system. In addition, Kingspan KoolDuct® panels have a non-fibrous insulation core, are non-deleterious, odorless and non-tainting. They will resist attack from mold and microbial growth and do not provide any food value to rodents or vermin.


Thermal Performance  The thermal conductivity (k-value) of Kingspan KoolDuct® panels is 0.146 Btu·in/hr·ft²·ºF at 50ºF (ASTM C 518), the lowest of any commonly used insulation material. A low thermal conductivity allows thinner insulation to achieve the required thermal performance. The installed material thermal resistances (R-values) for the range of panel thicknesses are shown in the table below:


Fire and Smoke Performance  Kingspan KoolDuct® panels have a resistance to burning and spread of flame far superior to that of rigid polyurethane (PUR) or rigid polyisocyanurate (PIR) insulations. In addition, there is an almost complete absence of smoke when the panels are subjected to a flame source. The insulation core of the panels is thermoset and unlike thermoplastic materials it does not melt, drip or produce flaming droplets. The panels successfully pass the Burning Test (UL 181) and do not exceed flame spread / smoke developed indices 25/50 (ASTM E 84 / UL 723).


Code Compliance & Approvals  Ductwork fabricated from the Kingspan KoolDuct® System satisfies the requirements of ANSI/ASHRAE/IESNA 90.1:2007, IECC 2003, 2006, 2009 & 2012, IMC 2009 and other major national specifications. KoolDuct complies with the requirements of NFPA Standards 90A & 90B and is UL Listed as a Class 1 Air Duct to Standard for Safety UL 181 when fabricated using: Kingspan KoolDuct® panels faced on both sides with factory applied silver aluminum foil; the aluminum grip flange and / or tiger jointing systems; and an aluminum foil vapor barrier tape that is UL Listed to Standard for Safety UL 181 A-P
