Oppfinnelsen angår en metallplate (15) for ventilasjons/røykutløpskanalseksjon (10) for inkludering i en metallplateventilasjon/røykutløpskanal, idet metallplatene (15) er tildekket på utsiden av et varmeisolerende materiale (7), og idet kanalseksjonen (10) innbefatter langstrakte avstivningsstangelementer (30) lokalisert på utsiden av kanalen og fastgjort til metallplaten (15), idet oppfinnelsen utmerker seg ved at stangelementene (30) er lokalisert ved en avstand fra metallplatene (15), idet stangelementene (30) er fastgjort til metallplatene (15) ved adskilte lokaliseringer langs lengden av stangelementene (30). The invention relates to a metal sheet (15) ventilation/smoke exhaust duct section (10) for incorporation into a metal sheet ventilation/smoke exhaust duct, said metal sheets (15) being covered on the outside by a heat insulating material (20) and said duct section (10) including elongated stiffening bar members (30) located on the outside of the duct and attached to said metal sheets (15), the invention being characterised in said bar members (30) being located at a distance from said metal sheets (15), said bar members (30) being attached to said metal sheets (15) at discrete locations along the length of the bar members (30).
