OverviewThe heating, ventilation and air–conditioning (HVAC) industry isin the midst of a dynamic era. However, air–distributionductwork, a critical component of HVAC systems, hasremained virtually unchanged since the early 1900s.

Several factors have introduced the need to revolutionise HVACductwork. Energy use has continued to escalate, and thus thedemand for energy reducing solutions has intensified.Requirements for clean air are becoming increasingly prevalent.Speed of construction has become a valuable asset. Floorspace and headroom are under constant pressure.

Ductwork fabricated from The Kingspan KoolDuct® System isUL Listed as a Class 1 Air Duct, to Standard for Safety UL 181(Factory Made Air Ducts & Air Connectors), when fabricated toa specification clearly defined by UL.

Introduction

The Kingspan KoolDuct® System eliminates virtually all of theproblems associated with galvanised sheet steel, mineral fibreduct board and pre–insulated rigid polyisocyanurate (PIR)ductwork systems whilst, at the same time, offering additionaladvantages to the specifying engineer, the architect, the M&Econtractor, the fabricator, the facilities manager, the propertydeveloper and the building owner.

In addition, ductwork fabricated from The Kingspan KoolDuct®

System can reduce air–leakage rates to a fraction of those typicalof rectangular sheet metal ductwork. This cutting edge Systemthus offers the triple benefits of cutting energy use, cuttingoperational carbon dioxide (CO2) emissions and cutting costs.

As a result, The Kingspan KoolDuct® System should beconsidered the ductwork system of choice, where low embodiedenvironmental and low operational environmental impacts arekey requirements.

Traditionally, HVAC ductwork is constructed from galvanisedsheet steel, which is installed first and then insulated separatelyas a second operation. The Kingspan KoolDuct® Systemhowever, is an advanced and innovative pre-insulated rectangularHVAC ductwork system, which is installed in a single–fix.

Introduction

What is The Kingspan KoolDuct® System?The Kingspan KoolDuct® System comprises premiumperformance Kingspan KoolDuct® panels, fabrication methods,coupling systems and a complete line of accessories toproduce pre–insulated rectangular ductwork in sections upto 2.95 m long.

Kingspan KoolDuct® panels are available in a standard thicknessof 30 mm. They comprise a fibre–free rigid thermoset phenolic

insulation core faced either with silveraluminium foil on both sides, orsilver aluminium foil onone side and black

coated aluminium foil on the other. In addition,there are several coupling systems available tosuit different installation and project specificationrequirements. They include the 4–bolt, aluminium gripand Tiger Clip systems.

The design of ductwork, including fittings, fabricated fromThe Kingspan KoolDuct® System, follows the same calculationprinciples and duct sizing methods as are used for ductworkconstructed from galvanised sheet steel.

The fabrication of ductwork from The Kingspan KoolDuct®

System is accomplished by following a standardised procedure,which incorporates the following processes:

● manually tracing / digitally nesting the outlines ofductwork sections, fittings and plenum boxes onto theinternal surface of Kingspan KoolDuct® panels;

● cutting bevelled edges at different angles along theoutlines to form folded or butted mitre joints, bevelledmale–female joints and non–bevelled joints using eitherhand tools for manual fabrication, or CNC blade / routermachinery for automated fabrication;

● assembling the cut pieces into the desired shape andsecuring into place with Kingspan KoolDuct® SystemAdhesive or Tiger Clips;

● taping joints and exposed insulation edges with a protectiveand durable aluminium foil vapour barrier tape;

● reinforcing ductwork sections and fittings, if required;

● sealing the internal side of all mitre joints with KingspanKoolDuct® System High Performance Silicone Sealant;

● coupling ductwork sections and fittings; and

● inspecting finished ductwork to ensure that it is fit for thepurpose intended.

Kingspan Insulation offers a complete product line, providing allmaterials, tools and accessories necessary for the effectivefabrication of ductwork from The Kingspan KoolDuct® System.Further details are contained in The Kingspan KoolDuct®

System Component Catalogue.

Accurate fabrication and best practice installation are crucial inensuring compliance with legislation, delivering required thermalperformance levels and reducing air–leakage rates to aminimum. As a result, ductwork from The Kingspan KoolDuct®

System is only fabricated by specially trained fabricators whohave completed The Kingspan KoolDuct® System TrainingCourse, and who are registered on The Kingspan KoolDuct®

System Competent Person's Database. The required standardsof fabrication are detailed in The Kingspan KoolDuct® SystemFabrication Manual series of publications,

In 1982, the System went global, having proved its success insouthern European markets. However, by the end of thefollowing decade, legislation governing fire safety in buildingshad dramatically increased in stringency. In 1992, the insulantwas accordingly upgraded to a new material that not onlyoffered far superior fire and smoke performance, but also anunrivalled thermal performance. This cutting edge material wasa premium performance rigid thermoset phenolic insulant,developed by Kooltherm Insulation Ltd. In that same year, theSystem was re–launched as The Pal KoolDuct® System.

In 1996, Kingspan Group plc acquired KoolthermInsulation Ltd and eventually assimilated it intoKingspan Insulation Ltd, which subsequentlybecame responsible for marketing the System inthe UK and Ireland as The Kingspan KoolDuct®

System. Responsibility in all othergeographical regions was maintained by

Pal International Srl, which continued topurchase the premium performanceinsulant from Kingspan IndustrialInsulation Ltd.

Four years later, ductwork fabricatedfrom the System became UL Listedto Standard for Safety UL 181(United Laboratories: Factory MadeAir Ducts & Air Connectors), whenfabricated to a specification clearly

defined by UL.

In 2007, Kingspan InsulationLtd acquired the rights fromPal International Srl for themarketing and development ofthe System in all geographicalregions, except for the USA

and Canada. This swiftly changed in2009, when Kingspan Insulation Ltd expanded

its operations across these two countries, subsequentlyassuming full global responsibility for the System.

In 2010, the premium performance pre–insulated rectangularHVAC ductwork system was relaunched as The KingspanKoolDuct® System, in all geographical regions.

HistoryThe history of The Kingspan KoolDuct® System dates back to1965 when the world’s first system of pre–insulated HVACductwork, which used aluminium faced rigid polyurethane(PUR) insulation boards in place of mineral fibre insulated sheetmetal, was established by Claudio Ferraro of Pall. In the fiveyears that followed, innovations in materials science hadfacilitated the development of insulants with improved fire andthermal performance. As a result, the insulant was changed, in1970, to rigid polyisocyanurate (PIR).

What is Different about The KingspanKoolDuct® System?The Kingspan KoolDuct® System offers numerous benefits incomparison with insulated galvanised sheet steel, mineral fibreduct board and pre–insulated rigid polyisocyanurate (PIR)ductwork systems. Benefits include, but are not limited to,the following:

● UL Listed – UL Listed as a Class 1 Air Duct, to Standard forSafety UL 181 (Underwriters Laboratories: Factory Made AirDucts & Air Connectors), when fabricated to a specificationclearly defined by UL;

● low weight – weighs up to 75% less than ductworkconstructed from galvanised sheet steel and insulated withmineral fibre – this makes it ideal for refurbishment projects,where existing building structures have insufficient loadcapacities for new service loads;

● faster installation speeds – low weight ductwork fabricatedin sections up to 2.95 m long, single–fix installation and noneed to install insulation as a second operation, reducesproject scheduling periods for insulated ductwork;

● space saving – typically saves up to 150–200 mm in asingle dimension, since the space required to manuallyinstall a separate layer of insulation around the ductwork iseliminated – this allows ductwork to be installed flush toceilings, walls and floors, as well as to surfaces withinconfined enclosures;

● installed cost savings – reduced labour and materials,including fixings and first level support members, canprovide an ideal value engineered ductwork solution withoutcompromising performance;

● low air–leakage – rates can be reduced to a fraction ofthose typical of rectangular sheet metal ductwork;

● reduced energy usage and running costs – low ductworkair–leakage can yield significant electrical consumptionsavings because of reduced heating and cooling loads, andfan energy usage;

● easily modified – ductwork configurations can be easilymodified and adapted onsite to deal with unexpectedchanges to the design, which may be required tocircumvent unforeseen obstructions and other buildingdesign issues;

● whole life cost saving – up to 20% over 30 years,compared with ductwork constructed from galvanised sheetsteel and insulated with mineral fibre;

● low embodied environmental impact – up to 65% less thanthat of rock mineral fibre insulated galvanised sheet steelductwork;

● reduced operational carbon dioxide (CO2) emissions – asa result of low ductwork air–leakage, and the subsequentreduction in operational energy use;

● reduced workshop–generated waste – computer aidedfabrication can greatly reduce the volume of waste,compared with manual fabrication; and

● a fibre–free rigid insulation core – minimises the risk ofloose fibres entering the airstream through the ductwork,since distributed air does not come into contact with aninsulation material that produces loose fibres.

Further information on each of the above can be found in theBenefits section of this document.

Applications

SuitabilityThe Kingspan KoolDuct® System is designed for use in buildingservices / HVAC applications. It is suitable for both new build andrefurbishment projects in the residential, commercial, public, lightindustrial and leisure sectors. Moreover, it is especially suitablefor use in non-ferrous applications such as MRI scanning units inhospitals, and on other high specification projects where non-fibrous 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 andcommunication / server rooms in data centres.

*For swimming pools, non–standard applications and project specific advice, please contactKingspan Insulation.

Ductwork fabricated from The Kingspan KoolDuct® System canbe installed indoors, outdoors visibly mounted, concealed abovefalse ceilings, concealed below raised floors or within confinedenclosures such as pre–fabricated modules. Furthermore, itsversatility enables individual system components, such as plenumboxes, risers and straight sections, to be integrated with sheetmetal ductwork, whilst larger sized ducts, with a cross–sectionaldimension greater than 2 m, are easily fabricated.

The availability of Kingspan KoolDuct® panels with a blackcoated facing makes them ideal for use in the fabrication of pre–insulated plenum boxes, as well as for projects that require anunobtrusive air–distribution solution without the added expense ofa cosmetic surface finish e.g. theatres, cinemas and nightclubs.

Operating Recommendations & LimitationsIt is recommended that ductwork fabricated from The KingspanKoolDuct® System is used for operation as supply, return,fresh and exhaust air ductwork for heating, ventilation andair–conditioning systems within the following limits:

Mean Air Velocity (Max.) 25.4 m/s

Design Pressure (Max.)* Positive: 1000 PaNegative: 750 Pa

Benefits

UL ListingDuctwork fabricated from The Kingspan KoolDuct® System is ULListed as a Class 1 Air Duct, to Standard for SafetyUL 181 (Underwriters Laboratories: Factory MadeAir Ducts & Air Connectors). The UL Listing requiresthat ductwork is fabricated using:

● 20–33 mm Kingspan KoolDuct® panels, facedwith silver aluminium foil autohesively bonded to theinsulation core, on both sides, during their manufacture atKingspan Insulation’s Pembridge, UK, manufacturing facility;

● either, or a combination of, the 4-bolt, the aluminiumgrip and / or Tiger Clip coupling systems;

● an aluminium foil vapour barrier tape that is UL ListedA–P to Standard for Safety UL 181 A (UnderwritersLaboratories: Standard for Closure Systems for use withRigid Air Ducts); and

● Kingspan High Performance Silicone Sealant / Caulk.

To meet UL Class 1 Air Duct requirements, ductwork fabricatedfrom The Kingspan KoolDuct® System and / or the individualcomponents from which it is fabricated, must withstand thestringent conditions to which they are subjected in a series ofrigorous physical tests. They include: surface burningcharacteristics; burning; flame penetration; mould growth andhumidity; puncture; pressure; corrosion; erosion; static load;impact; collapse; air–leakage; and low and high temperatures.

The results of the UL Fire Test Standards achieved by KingspanKoolDuct® panels, faced with silver aluminium foil on bothsides, are shown in Table 2.

To maintain the UL Listing for ductwork fabricated fromThe Kingspan KoolDuct® System, Kingspan Insulation must:deliver a programme of production control; regularly providesamples for audit testing; and allow unannounced periodicinspections of the manufacturing facility that produces KingspanKoolDuct® panels, by UL representatives.

Further details of the UL Listing for ductwork fabricated fromThe Kingspan KoolDuct® System are published at: www.ul.com inthe 'Online Certifications Directory'. To view the listing, type‘Kingspan Insulation’ under the search parameter ‘CompanyName’, followed by ‘MH25124’ under the search parameter‘UL File Number’.

Fire PerformancePropertiesThe insulation core of Kingspan KoolDuct® panels is a rigidthermoset material and, unlike thermoplastic materials, it doesnot melt, drip or produce flaming droplets. Its intricatelycross–linked structure makes it difficult to ignite and, whensubjected to fire, its outer surface forms a strong carbonaceouslayer that limits heat generation and retards further flamespread. Moreover, there is an almost complete absence ofsmoke, when subjected to a flame source.

In addition, the insulation core has a resistance to burning andspread of flame far superior to that of flexible elastomeric foam(FEF), rigid polyurethane foam (PUR) and rigid polyisocyanuratefoam (PIR) insulants.

ClassificationsKingspan KoolDuct® panels, faced either with silver aluminium foilon both sides, or with silver aluminium foil on one side and blackcoated aluminium foil on the other, and their rigid thermosetinsulation core, are Class 0, as defined by the Building Regulations.

Kingspan KoolDuct® panels, faced with silver aluminium foil onboth sides, are Euroclass Bs1d0, as defined by the EuropeanFire Classification System.

the number of vehicles, could be reduced. This could provide afurther benefit where the space and access required for theoff–loading of goods from large vehicles may be restricted.

Further information can be found at:www.kingspaninsulation.co.uk/ductwork-space.

WeightDuctwork fabricated from The Kingspan KoolDuct® Systemcan weigh up to 75% less than ductwork constructed fromgalvanised sheet steel and insulated with mineral fibre.

The low weight of ductwork fabricated from The KingspanKoolDuct® System can enable easier installation and muchlower handling costs, since fewer people are required to installa ductwork section. Two individuals can quickly and easilyinstall large ductwork sections.

Most 2.95 m long sections of ductwork fabricated fromThe Kingspan KoolDuct® System, regardless of the choice ofcoupling system, weigh 23 kg or less. This is below themaximum manual handling and lifting weight limits for anindividual in the workplace, as recommended by many healthand safety regulatory authorities.

For instance, a 2.95 m long ductwork section, fabricated tomeet the requirements for a 500 Pa low pressure HVAC systemand having an internal perimeter of 800 mm, a wall thickness of30 mm and using either the 4–bolt or aluminium grip couplingsystem, weighs less than 8.5 kg. A larger sized section, havingan internal perimeter of 3000 mm and using the Tiger Clipcoupling system, but otherwise the same as the aforementionedspecification, weighs less than 23 kg.

Tables of weights for ductwork sections fabricated from TheKingspan KoolDuct® System, of various dimensions and withthe different coupling systems, are contained in The KingspanKoolDuct® System Fabrication Manual series of publications.

SpaceDuctwork fabricated from The Kingspan KoolDuct® System isspace saving by virtue of eliminating the space required tomanually install a separate layer of insulation around theductwork. Moreover, ductwork fabricated from The KingspanKoolDuct® System can be installed flush to ceilings, walls andfloors, as well as to surfaces within confined enclosures. This cantypically save 150–200 mm of valuable space, making it ideal foruse in service runs, raised floors and pre–fabricated modules.

Thinner insulation, as a result of the insulating efficiency ofKingspan KoolDuct® panels, further contributes to spacesavings. The thermal conductivity (k–value / l–value) ofKingspan KoolDuct® panels is 0.022 W/m·K at 10°C mean(BS EN 12667: 2001 – Thermal performance of buildingmaterials and products. Determination of thermal resistance bymeans of guarded hot plate and heat flow meter methods.Products of high and medium thermal resistance). This makesKingspan KoolDuct® panels the most thermally efficient, andhence the thinnest, insulation product commonly used forpre–insulated HVAC ductwork. The range of declared thermalconductivities (lD) for Kingspan KoolDuct® panels are containedin The Kingspan KoolDuct® System Technical Data Sheet.

A cost analysis of the benefits that the aforementioned spacesaving ability has on floor–to–floor dimensions, in UK multi–storey buildings, was performed by independent consultantsRider Levett Bucknall. The results of the analysis showed that, if floor–to–floor heights can be reduced to take advantage ofthese space saving abilities, the use of ductwork fabricatedfrom The Kingspan KoolDuct® System, as part of a variable airvolume (VAV) air–conditioning system, can save 1–2% in overallproject construction cost. This saving comes predominantlyfrom reduced structure, cladding and internal wall, and wallfinishing costs.

In addition, ductwork fabricated from The Kingspan KoolDuct®

System can be supplied in flat form, ready for assembly onsite.Consequently, the load space required for the transportation ofpre–assembled ductwork from the workshop to site, as well as

Benefits

The low weight of ductwork fabricated from The KingspanKoolDuct® System makes it especially suitable for use inpre–fabricated modules, which may have to be transported longdistances to site. Moreover, the requirement for specialisedheavy–duty mechanical handling and lifting equipment can bereduced, which makes ductwork fabricated from The KingspanKoolDuct® System particularly favourable for riser sections thatspan multiple storeys in high–rise buildings.

Ductwork fabricated from The Kingspan KoolDuct® System canbe easily supported by lightweight wire systems or low gaugemetal hangers and supports. Furthermore, supports can beinstalled at larger centres than with ductwork constructed fromgalvanised sheet steel. The UL Listing for ductwork fabricatedfrom The Kingspan KoolDuct® System allows for a maximumspacing of 3.96 m centres for supports. Galvanised sheet steelductwork, on the other hand, often requires heavier and morerobust support systems e.g. rolled steel channel, angle orprofile bearer sections with drop rod, studding or stirruphangers, installed at smaller centres.

Many older buildings undergoing refurbishment may not bedesigned to support the additional weight of retrospectivelyinstalled sheet steel ductwork and its insulation. In suchcircumstances, ductwork fabricated from The KingspanKoolDuct® System can generally alleviate the requirement foradditional structural support.

Research, conducted in the UK by independent consultantsRider Levett Bucknall, into a number of refurbishment projectsin which ductwork fabricated from The Kingspan KoolDuct®

System, comprising 22 mm Kingspan KoolDuct® panels and thealuminium grip coupling system, was installed, has shown thatthe main reason for its specification was that it could overcomesevere constraints on structural loadings.

Further information can be found at:www.kingspaninsulation.co.uk/ductwork-weight.

Research, conducted in the UK by independent consultants RiderLevett Bucknall, into a number of refurbishment projects in whichductwork fabricated from The Kingspan KoolDuct® System,comprising 22 mm Kingspan KoolDuct® panels and thealuminium grip coupling system, was installed, has shown that themain reason for its selection was that it could be installed up tothree times faster than sheet steel ductwork – without even takinginto account the time required to install insulation separately as asecond operation. Rider Levett Bucknall also concluded that panelthickness has no effect on the speed of installing ductworkfabricated from The Kingspan KoolDuct® System.

In addition to a reduction in the risk of incurring penalties forlate completion of the insulated ductwork contract on someprojects (in addition to an increase in the possibility of attainingrewards for early completion), faster installation obviouslymeans lower costs and less disruption for other trades onsite.

Further information can be found at:www.kingspaninsulation.co.uk/ductwork-speed.

Installation SpeedDuctwork fabricated from The Kingspan KoolDuct® System hasa single–fix installation and eliminates the need to installinsulation as a second operation, thus reducing time onsite andcontractor 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 standard1.2 m or 1.5 m lengths, as is the case with sheet steel ductwork,means fewer sections and less handling. This, combined withthe low weight of ductwork fabricated from The KingspanKoolDuct® System, the requirement for fewer supports andease of handling, results in a fast–track installation.

11

Installed CostResearch, conducted in the UK by independent consultantsRider Levett Bucknall, into the installed cost of differinginsulated HVAC ductwork specifications, and subject toperiodic updates, continues to show that the installed cost ofductwork fabricated from The Kingspan KoolDuct® System isless expensive than that of ductwork constructed fromgalvanised sheet steel and insulated with mineral fibre.

The research utilises cost data submitted for a commercialproject from a number of ductwork and insulation contractorsacross the UK. It compares ductwork fabricated fromThe Kingspan KoolDuct® System, comprising 30 mm KingspanKoolDuct® panels and the 4–bolt coupling system, withgalvanised sheet steel ductwork insulated with 50 mm thickmineral fibre.

The ductwork system design, layout and performancespecification were identical for both ductwork specifications, aswere the building design and the distance required to travelfrom the workshop to site.

A summary of the total installed cost, (labour and materials,including fixings and first level support members), per linearmetre of ductwork, for the different duct sizes of each ductworkspecification, is shown in Table 3.

Benefits

Frictional Resistance, Air–leakage, EnergyUsage & Running CostsThe frictional resistance of ductwork fabricated from The KingspanKoolDuct® System is comparable with that of galvanised sheetsteel ductwork. Testing, conducted in the UK by independenttesting and research organisation BSRIA, on ductwork sections ofdifferent sizes with a range of fittings, has shown that at velocitiesof 2–20 m/s, the resistance to airflow is almost identical.

As a result, frictional pressure drop data for galvanised sheetsteel ductwork may also be used when designing ductworksystems fabricated from The Kingspan KoolDuct® System.

Furthermore, The Kingspan KoolDuct® System produces pre–insulated ductwork where the air–leakage rate can be reducedto a fraction of that typical of sheet metal ductwork. A lowair–leakage rate can yield significant electrical consumptionsavings, because of reduced heating and cooling loads, andreduced fan energy usage.

For ductwork systems designed to withstand a maximum staticpressure of 1000 Pa, ductwork fabricated from The KingspanKoolDuct® System, with different coupling systems, can easilyachieve the air–leakage classes shown in Table 4. Standardconstruction sheet metal ductwork, however, may find it difficultto achieve the same air–leakage classes.

Air–leakage Classes Achievablewith Different Coupling Systems

B&ES DW/144 (Building & Engineering Services Association – formerly known as theHeating & Ventilation Contractors Association' – Specification for Sheet Metal Ductwork,1998 Edition).

Table 4: Air–leakage Classes easily Achievable by Ductwork Fabricated fromThe Kingspan KoolDuct® System

Class C air–leakage is one third that of Class B, and Class D isone third that of Class C. As a result, specifying ductworkair–leakage Classes C or D can be a relatively simple, yetinexpensive, step to take toward reducing the overalloperational energy use of a building.

In order to illustrate this point, Kingspan Insulation commissioneda review, by independent testing and research organisationBSRIA, of the implication of ductwork specification and differentductwork air–leakage rates on energy consumption.

The methodology given in BSRIA’s report was used to comparea 100 m long run of ductwork fabricated from The KingspanKoolDuct® System, with a 100 m long run of galvanised sheetsteel ductwork. Both runs had cross–sectional internaldimensions of 600 x 600 mm.

BSRIA’s methodology demonstrated that ductwork fabricatedfrom The Kingspan KoolDuct® System can save 31% of theenergy, and thus cost, required to run a fan, in a HVAC systemwith a typical design flow rate of 7.5 m/s. This saving can beeven greater for lower design flow rates.

Kingspan Insulation commissioned a review by independentconsultants, Rider Levett Bucknall, of the implications ofreduced fan power on actual energy usage. Rider LevettBucknall concluded that for a 100 m long run of ductwork, withcross–sectional internal dimensions of 600 x 600 mm and an airvelocity of 7.5 m/s, ductwork fabricated from The KingspanKoolDuct® System could save 3100 kW·h per annum.

This energy saving equates to a saving of 1.3 metric tons ofCO2 equivalent emissions per annum, or 39 metric tons over30 years.

Rider Levett Bucknall carried out a further review of theimplications of reduced fan power, this time on fan size and capitalcost. The conclusion was that an 11.6% reduction in the size ofthe fan could be achieved, yielding a 10% capital cost saving.

Separate research, conducted in the US by mechanical andelectrical engineering services firm, MDA Engineering Inc.,under the auspices of Luther Home of Mercy, has also shownthat HVAC system running costs can be dramatically reducedas a result of the low air–leakage rate of ductwork fabricatedfrom The Kingspan KoolDuct® System.

The research utilised empirical data derived from theindependent testing of two HVAC installations, in two separatenew construction buildings belonging to Luther Home of Mercy.Both buildings had a ground floor area of 650m² and wereidentical in design. It compared an installation using ductworkfabricated from The Kingspan KoolDuct® System, comprising22 mm Kingspan KoolDuct® panels and the Tiger Clip couplingsystem, with an installation using galvanised sheet steelductwork insulated with 51 mm thick glass fibre duct wrap.The ductwork and HVAC system design, layout andperformance specification were identical.

The recorded air–leakage rate of the HVAC installation usingductwork fabricated from The Kingspan KoolDuct® System was79% less than that using glass fibre insulated galvanised sheetsteel ductwork. Furthermore, the former exceeded therequirements of SMACNA (Sheet Metal & Air ConditioningContractors' National Association) Air–leakage Class 24, with aleakage rate 64% of the maximum allowable. In contrast, thelatter failed to meet the requirements with a leakage rate morethan 3 times that allowable.

An analysis of the results showed that the substantial reduction inHVAC system air–leakage, achieved by the ductwork fabricatedfrom The Kingspan KoolDuct® System, yielded a correspondinglysignificant 70% reduction in projected first year running costsrelating to energy use – predicting that it would save 7120 kW•hper annum, or 213,600 kW•h over 30 years.

This substantial saving in energy equates to a CO2 emissionssaving of 5.7 metric tons per annum, or 170 metric tons over30 years. As a result, it is estimated that the ductwork fabricatedfrom The Kingspan KoolDuct® System would reduce CO2

emissions by 8.74 kg/m² of building floor area.

Luther Home of Mercy is a not–for–profit organisation based inWilliston, Ohio. It serves the community by providing careservices for people with developmental disabilities, and bysupporting independent living in residential cottages across itspurpose built campus, as well as in private homes and family carefacilities throughout the neighbourhood. This research wasconducted at two of its campus based residential cottages.

Modifications & RepairsDuctwork fabricated from The Kingspan KoolDuct® System canbe easily modified and adapted. For this reason, it is ideal forinstances when the configuration of a HVAC system needs tobe altered onsite e.g. to accommodate changes to the designof a building during the construction period.

Furthermore, the ability to modify and adapt ductworkfabricated from The Kingspan KoolDuct® System with ease,makes it especially suitable for buildings undergoingrefurbishment e.g. where space to manoeuvre is restricted, orunforeseen obstacles, discovered only after the works havestarted or after the building structure has been fully exposed,could cause delays and subsequent increases in associatedproject costs.

In addition, its low weight, flexibility and ability to be fabricatedboth onsite and offsite, allows modifications to be carried outquickly and with minimal disruption to business. This can beparticularly important in the retail, manufacturing and lightindustrial processing sectors where disturbances can result inunnecessary expense.

Research, conducted in the UK by independent consultantsCyril Sweett, has shown that ductwork fabricated fromThe Kingspan KoolDuct® System is subject to minimal damage,thus requiring minimal repairs, particularly where ductwork isinstalled within a ceiling void.

Nevertheless, localised damage to ductwork fabricated from theKingspan KoolDuct® System can be repaired in–situ, in anefficient and economical manner. This is opposed to replacing anentire ductwork section, which could be the case with someother ductwork systems and which could also prove to be costly.

Benefits

Notwithstanding the above, the integrity, and thus the lifespanand associated costs, of the ductwork are dependent upon it:

● continuing to operate within its original design parameters;

● not being subjected to external influences that may causedamage; and

● being subject to a regular maintenance programme.

Durability & LifespanDuctwork fabricated from The Kingspan KoolDuct® System isrigid, strong and self–supporting. When Kingspan KoolDuct®

panels are permanently formed to the desired shape, they havesufficient strength to maintain that shape. This has beendemonstrated in the field, and in the following tests withinStandard for Safety UL 181 (Underwriters Laboratories: FactoryMade Air Ducts & Air Connectors):

● puncture – the walls of ductwork sections preventingcomplete penetration of a 0.9 kg free–falling steel plunger;

● pressure & collapse – coupled ductwork sections resistingrupture and excessive deformation when subjected to positiveand negative pressures 2 ½ times their maximum rating;

● erosion – the ductwork, and its individual components,showing no sign of cracking, flaking, peeling ordelamination, when tested with an air velocity of 63.5 m/s(mean) – 2 ½ times its maximum rating;

● static load – coupled ductwork sections not sagging,permanently deforming or being damaged, with joints andseams remaining intact and not fracturing, as a result ofwithstanding the applied static loadings; and

● impact – coupled ductwork sections maintaining theirintegrity when subjected to impact from a 6.8 kg sandbag.

Maintenance & CleaningRegulation 5 of the Workplace (Health, Safety and Welfare)Regulations 1992, Approved Code of Practice, requiresmechanical ventilation systems, including ductwork, to bemaintained in an efficient state, in efficient working order and ingood repair. This includes being cleaned, as appropriate.

Poorly maintained and dirty ducts could contribute to increasedcosts. For instance, the accumulation of dust and debris couldnegatively affect the volume of airflow at registers or diffusers,subsequently increasing HVAC system energy usage, andtherefore operating costs.

Ductwork fabricated from The Kingspan KoolDuct® System canbe easily and economically cleaned to industry standards, asrequired by BS EN 15780: 2011, BS EN 13403: 2003 andB&ES TR/19 (refer to Table 5 for full titles), using many of thedry and non–abrasive cleaning methods offered throughprofessional HVAC ductwork cleaning specialists.

Suitable cleaning methods include the following:

● an air nozzle, comprising a perforated plastic ball placed onthe end of a flexible hose, which uses low or high volumecompressed air;

● an air lance, which directs low volume compressed airlocally through an airgun with a trigger;

● mechanical brushing with a soft and non–abrasive rotarybrush to brush the surface of the ductwork;

● hand wiping and manual brushing with soft andnon–abrasive materials; and

● electric / manual vacuuming to gently remove dust anddebris through suction.

Other methods, depending upon the nature of the deposit tobe removed, may be also suitable. For verification of cleaningmethods not listed above, please contact Kingspan Insulationprior to usage.

NB Ductwork fabricated from The Kingspan KoolDuct® System is unsuitable for wet cleaningmethods and any techniques considered as being abrasive e.g. hard brushing, scraping orcompressed air systems using metal balls. Dust, debris and particulates should be collectedusing an air movement and containment device with appropriate filtration for contaminants.

Indoor Air Quality (IAQ) Kingspan KoolDuct® panels have a fibre–free insulation coreand are odourless, non–tainting, non–deleterious, andchemically inert and safe to use.They will also resist attack frommould and microbial growth.Similarly, Kingspan KoolDuct® SystemHigh Performance Silicone Sealant is resistant to mould growth.At the end of the test period in the mould growth and humiditytest within Standard for Safety UL 181 (UnderwritersLaboratories: Factory Made Air Ducts & Air Connectors),ductwork fabricated from The Kingspan KoolDuct® Systemshowed no visible signs of mould growth beyond the areas ofinnoculation.

In addition, ductwork fabricated from The Kingspan KoolDuct®

System has been tested in the US by independent testing andresearch organisation Air Quality Sciences Inc. The results haveshown that emissions of volatile organic compounds (VOCs),formaldehyde, total aldehydes and total phthalates arenegligible, and well below the maximum allowable limitsdeemed safe for schools in the US.

Furthermore, air distributed through ductwork fabricated fromThe Kingspan KoolDuct® System does not come into contact withan insulation material that produces loose fibres. When sheetmetal ductwork that is insulated with mineral fibre leaks air, loosefibres could get blown off the duct into the general environment,and then into recirculation systems and back into the air–handlingsystem. Similarly, for ductwork operating at negative staticpressures, the loose fibres could potentially get drawn into theairstream flowing inside the duct, by entering through the seams.

Nevertheless, it is best practice to ensure that ductwork, and allparts of a HVAC system, meet specified levels of cleanliness.This includes newly installed ductwork prior to commissioningand / or handover, such that any surplus material remainingfrom the fabrication and installation process is fully removed.This is particularly important for applications in sensitive areas,where a hygiene–controlled environment is required e.g. inclean rooms, operating theatres, hospitals, food processingfacilities and pharmaceutical manufacturing plants.

Whole Life Cost‘Whole life costing’ takes account of the total cost of an item over itslife including, but not limited to, capital, operating and maintenancecosts. Kingspan Insulation commissioned two separate analyses ofthe whole life costs of differing HVAC systems.

One analysis, performed by independent consultants CyrilSweett, utilised a combination of empirical and published databased upon a commercial building in the UK. It comparedductwork fabricated from The Kingspan KoolDuct® System,comprising 22 mm Kingspan KoolDuct® panels and thealuminium grip coupling system, with ductwork constructedfrom galvanised sheet steel and insulated with 40 mm thickmineral fibre. Both ductwork specifications were designed tomeet the same performance standards.

The other analysis was performed by mechanical and electricalengineering services firm, MDA Engineering Inc., under theauspices of Luther Home of Mercy, in the US. The analysisutilised empirical data derived from the independent testing oftwo HVAC installations, in two separate buildings of identicaldesign. It compared an installation using ductwork fabricatedfrom The Kingspan KoolDuct® System, comprising 22 mmKingspan KoolDuct® panels and the Tiger Clip couplingsystem, with an installation using galvanised sheet steelductwork insulated with 51 mm thick glass fibre duct wrap.The ductwork and HVAC system design, layout andperformance specification were identical.

The analysis of the UK ductwork specifications showed that, over30 years, ductwork fabricated from The Kingspan KoolDuct®

System can provide a whole life cost saving of over 20%.

Further information can be found at:www.kingspaninsulation.co.uk/ductwork-wlc.

Likewise, the analysis of the US ductwork installationsshowed that, also over 30 years, ductwork fabricated fromThe Kingspan KoolDuct® System is predicted to save anestimated 14% on whole life cost.

Further information can be found at:www.kingspaninsulation.co.uk/ductwork-luther.

Kingspan Insulation commissioned independent buildingresearch organisation, BRE, to carry out an embodiedenvironmental impact assessment of two differing HVACductwork specifications, both designed to meet the sameperformance standards.

BRE used its 2008 Environmental Profiles Methodology tocompare the overall embodied environmental impact ofductwork fabricated from The Kingspan KoolDuct® System,comprising 30 mm Kingspan KoolDuct® panels and the 4–boltcoupling system, with that of ductwork constructed fromgalvanised sheet steel and insulated with 50 mm thick rockmineral fibre.

The findings, presented in the form of ‘Ecopoints’, show thatthe embodied environmental impact of ductwork fabricatedfrom The Kingspan KoolDuct® System can be 65% lower thanthat of rock mineral fibre insulated galvanised sheet steel.

Furthermore, 86% of the impact of the rock mineral fibreinsulated galvanised sheet steel ductwork, is accounted for bythe galvanised sheet steel alone.

Environmental Impact & ResponsibleSourcingOzone Depletion Potential (ODP) & Global WarmingPotential (GWP)The insulation core of Kingspan KoolDuct® panels ismanufactured with a CFC/HCFC–free blowing agent that haszero Ozone Depletion Potential (ODP) and low Global WarmingPotential (GWP).

WasteComputer aided fabrication of ductwork from The KingspanKoolDuct® System can enable a sizeable reduction in thevolume of workshop–generated waste, compared with manualfabrication. Furthermore, the ability to pre–fabricate ductworksections and fittings in the workshop, to be supplied in flat formready for assembly onsite, minimises site–generated waste.

Responsible SourcingKingspan KoolDuct® panels, produced at Kingspan Insulation'sPembridge manufacturing facility, are certified 'Very Good' toBES 6001 (Framework Standard for the Responsible Sourcingof Construction Products).

Copies of the certificate can be found at:www.kingspaninsulation.co.uk/certification.

Green Guide RatingAn Ecoprofile, certified by BRE (Building Research Establishment)Certification to the 2008 BRE Environmental Profiles Methodology,has been created for Kingspan KoolDuct® panels produced atKingspan Insulation’s Pembridge, UK, manufacturing facility.Independent building research organisation, BRE, has assignedthe panels a 2008 Green Guide Summary Rating of A.

The methodology provides comparable environmentalinformation about competing building materials. It takes intoconsideration a range of environmental impacts across theirentire lifecycle, from cradle to grave, over a 60 year period,including disposal at end of life. It does not consider operationalenvironmental impacts or benefits.

The resultant data, presented in the form of ‘Ecopoints’, is usedby the 2008 Green Guide Rating system to classify theperformance of a product in a number of key areas. Using aweighting process, it awards a Summary Rating on a scalefrom E (worst) up to A+ (best).

Embodied Environmental Impact ComparisonIn comparing the embodied environmental impact of buildingproducts, the concept of a functional unit must be taken intoaccount. If a comparison is to be made between ductworkfabricated from The Kingspan KoolDuct® System, and ductworkconstructed from galvanised sheet steel and insulated withmineral fibre, then the functional unit must not only include theinsulation, but also the sheet steel, which is absent fromductwork fabricated from The Kingspan KoolDuct® System.

Operational Environmental Impact & AssociatedCarbon Dioxide (CO2) EmissionsFor buildings designed to today’s energy use standards, theembodied environmental impacts of all of the materials andlabour used to construct a building are insignificant incomparison with the lifetime operational environmental impactsof that building, and are thus of very limited importance.

In the case of insulated HVAC ductwork, saving energy, byspecifying the best ductwork air–leakage and heat loss / gainstandards possible, is the most environmentally sustainableaction to take when specifying ductwork and its insulation,since it is operational energy use that creates the vast majorityof operational environmental impact.

Low ductwork air–leakage is known to have a beneficial impacton the energy consumption of the fan delivering the air into theductwork system, and therefore on HVAC system energy usageand associated operational CO2 emissions. This relates notonly to the air–distribution HVAC system, but also to thebuilding in which it is installed.

The significance of a low ductwork air–leakage rate in cuttingoperational energy use, and thus associated CO2 emissions isclearly demonstrated by the findings from both the UK and USresearch programs described in the Frictional Resistance,Air–Leakage, Energy Usage & Running Costs section of thisdocument. For details, refer to page 12.

BREEAM 2011Ductwork fabricated from The Kingspan KoolDuct® System cancontribute directly, and indirectly, toward the achievement ofcredits in the 2011 version of the building rating system,BREEAM (Building Research Establishment EnvironmentalAssessment Method), which is owned and operated by BRE(Building Research Establishment). The relevant credits are:

● Mat 4 – Insulation; and

● Ene 1 – Reduction of CO2 emissions.

Mat 4 aims to recognise and encourage the use of thermalinsulation, which has a low embodied environmental impactrelative to its thermal properties, and which has beenresponsibly sourced.

Ene 1 requires the demonstration of a defined improvement inthe performance of a building relating to its operational energydemand, energy consumption and CO2 emissions.

Clearly, thermal insulation and ductwork air–tightness are twohighly effective ways to reduce a building’s operational energydemand, energy consumption and CO2 emissions.
