Abstract

A fire protection element is useful for the separation of openings passing through walls or ceilings, in particular of line passages. The fire protection element has a molded part made from intumescent material with a plurality of through-openings for the passage of lines which extend in particular parallel to each other from a first side to an opposite second side of the fire protection element. In each case, the through-openings for the passage are tightly sealed relative to flue gas by a membrane.
