Low air-leaking energy efficient pre-insulated ductwork for building services/ HVAC applications.
Suitable for use in HVAC systems.
An energy-efficient ductwork solution for HVAC applications offering premium thermal performance and reducing air leakage to a fraction of typical sheet metal ductwork. The system is comprised of rigid phenolic insulation panels with aluminium facings and includes fabrication methods, jointing systems and accessories.
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.
Features and benefits:
The recommended operational limits for ductwork fabricated from the Kingspan KoolDuct® System:
- Quality Control:
Kingspan KoolDuct panels are manufactured to the highest standards under a quality control system certified to:
CFC-free and HCFC-free with zero ozone depleting potential (zero ODP) and a global warming potential (GWP) of ≤5.
BREEAM – ductwork fabricated from The Kingspan KoolDuct® System can contribute directly, and indirectly, toward the achievement of credits in the building rating system, BREEAM. The relevant credits are Ene1 – Reduction of energy use and carbon emissions Mat 1 – Life Cycle ImpactMat 3 – Responsible sourcing of materials.
Certified to BES 6001 ‘Excellent’ (Framework Standard for Responsible Sourcing).
