Wat is het verschil tussen aluminiumfoliekanaal en semi-rigide aluminiumfoliekanaal

Aluminum foil ducts are widely used in HVAC systems for their flexibility, lightweight nature, and resistance to corrosion. Echter, there are variations in their design and construction, notably between standard aluminum foil ducts and semi-rigid aluminum foil ducts.

Wat is aluminiumfoliekanaal

Made of flexible aluminum foil, dit is het meest voorkomende type voor overgangskanalen voor drogers – kanalen die van het apparaat aansluiten op het hoofdkanaal dat naar buiten loopt. Foliekanaal kan accordeon vanaf ongeveer 1 naar 8 voeten, wat meestal voldoende is voor de meeste installaties. Controleer nogmaals of dit type is goedgekeurd voor uw droger en is toegestaan ​​volgens de lokale code. Transition ducts must not be concealed inside walls or other building cavities and usually have a maximum allowed length of 8 voeten. Foil duct is held in place with dryer clamps or large hose clamps. Metal tape can be used, too, but clamps make it easier to remove the tubing for cleaning.

What is Semi-Rigid Metal Duct

Semi-rigid metal (usually aluminum) duct is flexible and similar to foil ducting but quite a bit more rigid. Like foil duct, semi-rigid is used only for transition ducting and should not be concealed in walls or floors. It is typically installed with clamps. Although semi-rigid metal duct is often stronger and has a smoother interior (catches less lint) than foil duct, it is more common to find listed foil duct than listed semi-rigid.

AspectAluminum Foil DuctSemi-Rigid Aluminum Foil Duct
IsolatieNo inherent insulation; additional wrapping requiredBuilt-in insulation reduces heat loss/gain
DuurzaamheidLess durable, prone to punctures and tearsMore durable due to layered construction

Noise ReductionMinimal noise reductionReduces noise transmission through insulation

Toepassingen

  • Aluminum Foil Duct:
    • Used in areas where space is limited or where flexibility is key, like connecting HVAC units to vents in residential or commercial buildings.
    • Suitable for short runs or where the duct needs to navigate through tight spaces.
  • Semi-Rigid Aluminum Foil Duct:
    • Ideal for longer runs or where maintaining insulation is crucial, such as in commercial buildings, industrial settings, or for outdoor applications where temperature control is necessary.
    • Often used in environments where noise reduction is beneficial, like in hospitals or office buildings.
