The KoolDuct System

Pre-insulated ductwork system

The Kingspan KoolDuct System is an advanced and innovative pre-insulated rectangular HVAC ductwork system, which is installed in a single fix. The Kingspan KoolDuct System eliminates virtually all of the problems associated with galvanised sheet steel lagged with mineral fibre, whilst, at the same time, offering additional advantages to the specifying engineer, the architect, the M&E contractor, the fabricator, the facilities manager, the property developer and the building owner.

KoolDuct Panels - Technical Data
The Kingspan KoolDuct System is designed for use in building services / HVAC applications. It is suitable for both new build and ressidential, commercial, public, light industrial and leisure sectors. Moreover, it is especially suitable for use in non-ferrous applications such as MRI scanning units in hospitals, and on other high specification projects where nonfibrous insulants may be preferred, for instance, in:

● the food, beverage and pharmaceutical industries;
● clean air and hygiene controlled environments;
● high relative humidity environments;
● swimming pools; and
● sterile areas in medical research and healthcare facilities and communication / server rooms in data centres.

Fire Performance

Kingspan KoolDuct panels, faced with silver aluminium foil on both sides, are Euroclass B-s1,d0, as defined by the European Fire Classification System.

Space Savings

Ductwork fabricated from The Kingspan KoolDuct System typically saves up to 150–200 mm in a single dimension, since the space required to manually install a separate layer of insulation around the ductwork is eliminated – this allows ductwork to be installed flush to ceilings, walls and floors, as well as to surfaces within confined enclosures.


Low Weight

Ductwork fabricated from The Kingspan KoolDuct System can weigh up to 75% less than mineral fibre insulated galvanised sheet – this makes it ideal for refurbishment projects, where existing building structures have insufficient load capacities for new service loads.

The Weight White Paper can be downloaded from the downloads page. 

Installed Cost Savings

Ductwork fabricated from The Kingspan KoolDuct System can reduce labour and materials, including fixings and first level support members, can provide an ideal value engineered ductwork solution without compromising performance – over 15% less expensive.
Faster Installation Speed

The Kingspan KoolDuct System can be fabricated in sections up to 2.95 m long, ina a single–fix installation with no need to install insulation as a second operation. This can help reduce project scheduling periods for insulated ductwork.

The Speed White Paper can be downloaded from the downloads page. 
Low Air Leakage and Running Costs

With The Kingspan KoolDuct System, rates can be reduced to a fraction of those typical of rectangular sheet metal ductwork – can easily achieve: BS EN 1507: 2006 air–leakage Class D; BS EN 13403: 2003 Class C; and B&ES (HVCA) DW/144 Class C.

The Kingspan KoolDuct System can reduce air leakage rate to a fraction of that typical of sheet metal ductwork. This can yield significant electrical consumption savings because of reduced heating and cooling loads and reduced fan energy usage.

UL Listed

The Kingspan KoolDuct System is the only premium performance pre–insulated ductwork in the world to be UL Listed as a Class 1 Air Duct, to Standard for Safety UL 181 (Underwriters Laboratories: Factory Made Air Ducts & Air Connectors), when fabricated to a specification clearly defined by UL.
An Ecoprofile, certified by BRE Certification to the BRE Environmental Profiles methodology, has been created for Kingspan KoolDuct panels produced at Kingspan Insulation's Pembridge, UK, manufacturing facility. BRE has assigned the panels a 2008 Green Guide Summary Rating of ‘A’.

The Kingspan KoolDuct System can provide a low embodied environmental impact of up to 65% less than that of rock mineral fibre insulated galvanised sheet steel ductwork and can reduce operational CO2 emissions as a result of low ductwork air–leakage, and the subsequent reduction in operational energy usage.

Ductwork fabricated from The Kingspan KoolDuct System can contribute directly, and indirectly, toward the achievement of credits in the 2011 version of the building rating system, BREEAM. The relevant credits are ‘Mat 4 – Insulation’ and ‘Ene1 – Reduction of CO2 emissions’.

The insulation core of Kingspan KoolDuct panels is manufactured with a CFC/HCFC–free blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).
Whole Life Costs

The Kingspan KoolDuct System can provide a whole life cost saving of up to 25% over 30 years, compared with mineral fibre insulated galvanised sheet steel.
