Abstract
The invention relates to an insulation element ( ′), at least one nonwoven layer ( ) and/or a foam layer ( ) being enclosed by a film layer ( ), and, to achieve a solution which is adequately permeable to water vapour but nevertheless flame-retardant, proposes that the film layer ( ) consists of a flame-retardant material which is preferably closed to vapour diffusion, that the film layer ( ) also has through-openings ( ) and that the through-openings ( ) are open to vapour diffusion.
