Performance Solid Rigid ducting systems are suitable for use in all buildings to provide superior airflow performance vs. comparative size rectangular or flexible pvc or Aluminium duct. Suitable to use in compliance with Part F Building Regulations. Insulation of Ductwork It is important that any ducting located in a cold area (e.g. loft space) to be insulated. The insulation needs to be the equivalent of 25mm thick and have a thermal conductivity of 0.04W/(m.k) or less. This ensures that condensation doesn’t form due to the difference in air temperature inside the duct when compared to the air temperature in the cold space. If you don’t have a loft space there is still a need for insulated ducting on the intake and exhaust legs, as they will be carrying cold air in a warm space. The level of insulation can be achieved by wrapping PVC duct in a layer of 25mm duct wrap that has a silver foil face on a 25mm rockwool It is also worth noting that foil wrap with air bubbles (bubble wrap) is no longer applicable in building control regulations
