<p>A heat-insulating assembly (10) for insulating a surface of a tubular body (30) relative to the ambient air comprises a length of an annular heat-insulating body (12, 14) defining an inner cylindrical surface (17) and an outer cylindrical surface (16). A vapour-barrier layer is applied to and covers the outer cylindrical surface of the annular heat-insulating body. A through-going slit (11, 15) extends through the annular heat-insulating body (12, 14) in the entire length thereof for allowing the annular heat-insulating body (12, 14) to be opened for positioning the annular heat-insulating body (10) circumferentially encircling the tubular body (30) so as to position the inner cylindrical surface (17) juxtaposed the surface of the tubular body (30). A strip (24) of a water transport-allowing material is further provided defining a width substantially smaller than the length of the annular heat-insulating body (10) and a length allowing the strip (24) to be arranged within the annular heat-insulating body (10) circumferentially encircling the tubular body (30) and extending through the slit (11, 15) of the annular heat-insulating body for presenting an exposed flap (26) of the strip (24) at the outer cylindrical surface (16) of the annular heat-insulating body (10) to be exposed to the ambient air for the evaporation of water transferred from the surface of the tubular body (30) to the flap (26) of the strip (24) through the strip.</p> |
