Abstract
A panel for self-supporting ducts, in particular air-conditioning ducts, made up of a core of mineral wool, covered on its external face with an exterior covering joined to the external surface of the core, the exterior covering including a sheet of aluminum and the sheet of aluminum being the outermost sheet of the exterior stack, wherein the sheet of aluminum exhibits, at least on its outwardly exposed face, diffuse reflection greater than its specular reflection.
Claims19
A panel for a self-supporting duct made up of a mineral wool core, the mineral wool core having an external face covered with an exterior covering joined to the external surface of the mineral wool core, said exterior covering comprising a sheet of aluminum and said sheet of aluminum being an outermost sheet of the exterior covering and having an outwardly exposed face, wherein said sheet of aluminum has, at least on said outwardly exposed face, a diffuse reflection greater than its specular reflection, wherein the diffuse reflection of said outwardly exposed face of the sheet of aluminum is at least twice as great as its specular reflection.
A panel for a self-supporting duct made up of a mineral wool core, the mineral wool core having an external face covered with an exterior covering joined to the external surface of the mineral wool core, said exterior covering comprising a sheet of aluminum and said sheet of aluminum being an outermost sheet of the exterior covering and having an outwardly exposed face, wherein said sheet of aluminum has, at least on said outwardly exposed face, a diffuse reflection greater than its specular reflection, wherein the other face of the sheet of aluminum has a specular reflection greater than its diffuse reflection.
A panel for a self-supporting duct made up of a mineral wool core, the mineral wool core having an external face covered with an exterior covering joined to the external surface of the mineral wool core, said exterior covering comprising a sheet of aluminum and said sheet of aluminum being an outermost sheet of the exterior covering and having an outwardly exposed face, wherein said sheet of aluminum has, at least on said outwardly exposed face, a diffuse reflection greater than its specular reflection, wherein a roughness parameter Sz of the outwardly exposed face of the sheet of aluminum, as measured according to the NF ISO 25178 standard, is greater than 20 micrometers.
