An insulating element (10) formed from a rigid foam material is rendered flame resistant by being provided with an outer skin (12) comprising glass fibre nonwoven (13) provided with a coating (14). The coating contains at least one metal oxide, preferably aluminium hydroxide and/or antimony oxide, which, together with a plasticiser-free dispersion of a copolymer based on vinylidene chloride and/or butadiene, can be applied to the glass fibre nonwoven (13) as an expanded paste. <IMAGE>
