Features
  • Coreduct™ is a modular rigid duct system with a variety of joiner and junction fittings, offering ease and flexibility when designing and installing effective air handling systems.
  • Coreduct™ has a low profile design that leaves more space for other building services.
  • Duct, joiners, brackets and T junctions are all delivered in convenient flat pack form for easy site handling and more efficient storage and transport. The parts simply pop up and fit with other Coreduct™ components.
  • Coreduct™ is rigid once assembled, lowering the risk of torn or squashed duct and under-performing air handling systems.
