The KoolDuct System

KoolDuct new

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.

Product information

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.

Kingspan KoolDuct panels, faced either with silver aluminium foil on both sides, or with silver aluminium foil on one side and black coated aluminium foil on the other, and their rigid thermoset insulation core, are Class 0, as defined by the Building Regulations.

Kingspan KoolDuct panels, faced with silver aluminium foil on both sides, are Euroclass Bs1d0, as defined by the European Fire Classification System.

Kooltherm Duct Comp
Ductwork fabricated from The Kingspan KoolDuct System is space saving by virtue of eliminating the space required to manually install a separate layer of insulation around the ductwork. Moreover, ductwork fabricated from The Kingspan KoolDuct System can be installed flush to ceilings, walls and floors, as well as to surfaces within confined enclosures. This can typically save 150–200 mm of valuable space, making it ideal for use in service runs, raised floors and pre–fabricated modules.


Ductwork fabricated from The Kingspan KoolDuct System can weigh up to 75% less than ductwork constructed from galvanised sheet steel and insulated with mineral fibre.

The low weight of ductwork fabricated from The Kingspan KoolDuct System can enable easier installation and much lower handling costs, since fewer people are required to install a ductwork section. Two individuals can quickly and easily install large ductwork sections.

Installed cost savings – reduced 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.
KDuct install
Ductwork fabricated from The Kingspan KoolDuct System has a single–fix installation and eliminates the need to install insulation as a second operation, thus reducing time onsite an contractor management through faster installation speeds.

The ability to fabricate ductwork from The Kingspan KoolDuct System in up to 2.95 m long sections, rather than the standard 1.2 m or 1.5 m lengths, as is the case with sheet steel ductwork, means fewer sections and less handling. This, combined with the low weight of ductwork fabricated from The Kingspan KoolDuct System, the requirement for fewer supports and ease of handling, results in a fast–track installation.

The Speed White Paper can be downloaded below.

KoolDuct - Speed White Paper

Low air–leakage – 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 produces pre– insulated ductwork where the air–leakage rate can be reduced to a fraction of that typical of sheet metal ductwork. A low air–leakage rate can yield significant electrical consumption savings, because of reduced heating and cooling loads, and reduced fan energy usage.

KoolDuct - Running Cost White Paper

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).
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.

Brynmor Jones Library

The University of Hull has opened a new chapter for its main library with a multi-million pound redevelopment, providing a light, modern facility which is supported with premium products such as The Kingspan KoolDuct System.


State of the Art Facility

A state-of-the-art manufacturing site near Belfast has been upgraded and expanded as part of a £35 million investment programme. The work on the facility, situated on one of Northern Ireland’s green field sites, included the installation of flat oval ductwork fabricated from Kingspan KoolDuct Panels.


Fashion Retail Academy

Truly timeless fashion design requires a blend of artistic vision and the highest quality materials. This same approach was fundamental when the Fashion Retail Academy was established 11 years ago. The campus combines carefully crafted spaces, tailored to the student’s needs, with a top quality specification, including the external use of the Kingspan KoolDuct System with a waterproof, VentureClad facing.
