<p>The present invention relates to a system for installing a fire door with energy saving structure capable of being applied when constructing or remodeling a building. The system for installing the fire door with the energy saving structure is capable of being applied not only when installing a new fire door but also when remodeling more efficient. Especially, the system for installing the fire door with the energy saving structure is capable of reducing prime costs and a construction period in comparison with a method of completely dismantling an existing door frame, completing installation and remodeling within a short time without damage to the building, repairing and maintaining the existing door frame with damaged surface or marks to be beautiful and clean, remarkably improving not only a dew-proofing capacity, but also an insulation capacity, a soundproof capacity, and airtightness such as a wind breaking capacity, and improving an energy reducing effect by remarkably reducing an energy loss not only when heating in winter, but also when cooling in summer. An upper door frame includes a first bent cover frame attached to the door frame to cover the indoor surface and a second bent cover frame attached to cover the outdoor surface.</p> |
