1. A sealing device for a double edge joint formed between a floor, a wall, or a ceiling and an adjacent first cladding and a spaced-apart second cladding of drywall having double-layer cladding, the sealing device comprising:
a sealing profile having
a holding portion,
a first base body for sealing a first edge joint on the first cladding, and
a second base body for sealing a second edge joint on the second cladding,
wherein the first base body has a first carrier portion which forms a first support for the first cladding, and the second base body has a second carrier portion which forms a second support for the second cladding,
wherein the holding portion extends between the first base body and the second base body and is configured to seal a gap between a holding rail of the drywall and the adjacent floor, the wall, or the ceiling,
wherein the first base body and the second base body are connected to one another via the holding portion and, in combination therewith, form a U-shaped receptacle for the holding rail of the drywall,
wherein the first base body has a first intumescent strip configured to be provided in a first recess facing the holding rail,
wherein the second base body has a second intumescent strip configured to be provided in a second recess facing the holding rail,
wherein the sealing profile has a first sealing web extending away from the first base body and a second sealing web extending away from the second base body,
wherein the first sealing web forms a first lateral contact surface for the first cladding and is configured to seal a gap between the holding rail of the drywall and the first cladding, and
wherein the second sealing web forms a second lateral contact surface for the second cladding and is configured to seal a gap between the holding rail of the drywall and the second cladding.
