Ductboard is manufactured from a high quality glass wool boardfaced on the external surface with a reinforced aluminum foil vapour barrier. The air stream surface is faced with a black non-woven
glass tissue.


  • Used mainly as insulation for airconditioning and HVAC systems.
  • May be used in commercial, industrial or residential air handling installations for cooling, heating, dual temperature or ventilation.
  • Ductboard is suitable for operating temperatures up to 120°C with a maximum air velocity of 10m/s
  • Offers exceptional sound absorbtion properties and reduces noise generated by airconditioning equipment.
