Constructed with a \u003cstrong\u003elaminated aluminium and polyester inner duct\u003c\/strong\u003e reinforced by a high-tensile steel wire helix — creating a smooth, seamless bore — and finished with an outer \u003cstrong\u003eglass wool insulation layer enclosed in an aluminium foil jacket\u003c\/strong\u003e, it prevents condensation on the duct surface in cold spaces and limits heat loss or gain in the airstream.
