The new fire retardant elements are characterized in that they are foam mouldings which are elastic in the moist state and contain a liquid flameproofing impregnation, and the fire retardant elements are protected against moisture loss before installation and solidify on drying after installation. A process for the production of such fire retardant elements and mouldings which comprise such fire retardant elements are likewise described and claimed.
