Abstract
A fire protection element can be used for sealing a combustible body, which penetrates an opening in a wall or ceiling, in the event of a fire. The fire protection element has a belt- shaped carrier from the edge of which tongues protrude transversely to the longitudinal direction of said carrier. The tongues are connected to the belt-shaped carrier, at least a significant proportion of the tongues are formed of a bimetal, and the tongues can move in one direction under the effect of heat. A fire protection material is applied to at least one side of the tongues. Furthermore, a method can be used for sealing a combustible body, which penetrates an opening in a wall or ceiling, in the event of a fire.
