The Kingspan KoolDuct® System is an energy efficient ductwork solution for HVAC applications. It comprises Kingspan KoolDuct® rigid phenolic insulation panels with aluminium facings on both sides, fabrication methods, jointing systems and a complete line of accessories to produce a pre-insulated duct System with premium thermal performance and where air leakage can be reduced to a fraction of that typical of sheet metal ductwork.

Applications:

It 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 design and frictional resistance:

Kingspan KoolDuct® rectangular ductwork, including fittings, follows the same calculation principles and duct sizing methods as are used for rectangular metal ductwork.

The frictional resistance is comparable with that of galvanized sheet steel ductwork.

Benefits include:

  • Low air-leakage - can meet air tightness Class C requirements of BS EN 13403: 2003 - BS EN 1507: 2006 BESA DW/144.
  • Installed cost savings - can provide an ideal value engineered solution.
  • Space saving - fits flush to ceiling.
  • Faster installation - up to three times faster.
  • Single fix installation - one less trade onsite and less disruption for others.
  • Lightweight (up to 75% lighter than sheet metal ductwork) - can overcome severe constraints on structural loading.
  • Non-fibrous insulation.

Operational limits:

The recommended operational limits for ductwork fabricated from the Kingspan KoolDuct® System:

  • Mean Air Velocity (maximum): 25 m/s
  • Design Pressure (maximum): Positive: 1000 Pa, Negative: 750 Pa.
  • Internal Air Temperature: -20ºC to +80ºC during continuous operation.
  • Size: Unlimited (provided that recommended Kingspan KoolDuct® fabrication techniques and installation procedures are strictly observed)
  • Ductwork located outdoors must be protected with a compatible weatherproof.

Standards:

- Quality Control:

Kingspan KoolDuct® panels are manufactured to the highest standards under a quality control system certified to:

  • BS EN ISO 9001: 2008 (Quality management systems. Requirements).
  • BS EN ISO 14001: 2007 (Environmental Management Systems. Requirements).
  • BS OHSAS 18001: 2007 (Health and Safety Management Systems. Requirements).

Sustainability:

Kingspan KoolDuct® insulation is CFC-free and HCFC-free, with zero Ozone Depleting Potential (zero ODP) and Global Warming Potential (GWP) ≤5.

Green Guide rating:

Kingspan KoolDuct® panels have been assigned a BRE Global Green Guide 2008 Summary Rating of A.

Ecoprofile:

The score obtained by Kingspan KoolDuct® from the life cycle assessment of BRE Global Environmental Profiles Methodology is 0.056 Ecopoints: the lower the Ecopoints, the lower the environmental impact.

BES 6001:

All Kooltherm®/KoolDuct® insulation boards manufactured by Kingspan Insulation in the UK are certified to BES 6001 ‘Excellent’ (Framework Standard for Responsible Sourcing).
