The inner core is constructed from a \u003cstrong\u003elaminated aluminium and polyester helix\u003c\/strong\u003e reinforced with a high-tensile steel wire, delivering a smooth, seamless bore that keeps pressure drop low. An outer \u003cstrong\u003eglass wool insulation layer\u003c\/strong\u003e enclosed within an aluminium foil jacket prevents condensation on the duct surface in cold installation environments and limits heat transfer between the airstream and the surrounding space.
