Abstract
A method can be used for producing a firewall in an opening of a building. In this case, at least one fire protection profile is used which contains a tube made of a composite material, which is filled with a fire protection material. The fire protection profile is designed such that it can be combined with an adjacent fire protection profile in the event of a fire. In order to produce the firewall, it is first transferred into an at least partially compressed state or provided in such a state. The fire protection profile is then introduced into the opening, with the at least partially compressed state being maintained. The fire protection profile is subsequently released so that it is decompressed at least partially and at least in portions.
