Insulated spiral ducts


Insulated spiral ducts are particularly suitable for connecting a ventilation system to an MVHR unit or air-to-water heat pump. The ducts have an insulated jacket on the outside to prevent condensation and heat loss.


A spiral duct, also known as a spiral pipe or circular tube, is made of galvanised steel. Spiral ducts are used to supply and extract air. They can be suspended from the ceiling or wall. The low price and long service life make the spiral ducts one of the most popular air ducts for ventilation. Several spiral ducts can be joined together to form a ventilation system using a variety of fittings.
