The ECO-AIR Isodec range of flexible acoustic ducting is extremely strong utilising multiple layers of aluminium foil with the wire helix closer together then normal flexible ducts.

The insulated outer core makes this ducting ideal for whole house ventilation systems when installed correctly

The ECO-AIR Sonodec range of flexible ducting is similar to the Isodec range but has a micro perforated inner core which provides acoustic insulation in addition the thermal insulation.
