I work in a room where there is a fire door in the hall way that makes an awful noise when opening. I think its due to the fire seal. Is it common for fire seals to do this and is there a way to make it better? Thanks

If the seal is making a noise when the door opens, it is most likely from the brush or fin that provides restricted smoke spread protection.  This type of seal needs to make light contact with the opposing surface in the door closed position so the noise is most likely due to friction.

If the noise is a problem you could change the seals (all of them) for fire only seals (below) used in conjunction with the type of smoke/acoustic seal (bottom).
