  • Publication number: 20220325826
    Abstract: The invention relates to a fire protection element (10) for sealing a combustible body, which penetrates an opening (22) in a wall or ceiling, in the event of a fire. The fire protection element (10) has a belt-shaped carrier (12) from the edge of which tongues (14) protrude transversely to the longitudinal direction of said carrier, which tongues are connected to the belt-shaped carrier (12), at least a significant proportion of the tongues (14) being formed of a bimetal, which tongues can move in one direction under the effect of heat. A fire protection material (18) is applied to at least one side of the tongues (14). Furthermore, a method for sealing a combustible body, which penetrates an opening (22) in a wall or ceiling, in the event of a fire is described.
