An acoustical seal system that utilizes a sound absorbing material-based sound seal for the gap or flanking path between a closed door and the nearby surfaces (e.g., the door jam or frame and the floor). When the door is in a closed position, the acoustical seal system may leave a small gap around the door so that the door does not have to make contact with the surrounding structural components. The small gap is an air passage between the two adjacent rooms. The acoustical seal system includes a housing with one or more cavities. The housing is mounted on the sides of the door core or body or on the surrounding components such that the cavities face the small air gap when the door is in the closed position. The cavities are filled with sound-absorbing material, such as an acoustical foam, that is exposed to the air gap.

[Object] To provide a door frame structure and a method for mounting the door frame structure which improve rigidity, prevent deformation that is caused by relative story displacement of a building in the event of an earthquake, and enable easy mounting. [Solution Means] A door frame structure 1 is indirectly mounted to a wall surface 4 via mounting angles 11 fixed to the first reinforcing members 9. Therefore, the door frame structure 1 does not follow relative story displacement of the wall surface 4 caused by lateral vibration in the event of an earthquake, so that deformation of the door frame structure 1 is minimized, and a door 31 can be opened and closed even in an emergency.

A sound damping door system having a door frame, a compression seal, a door slab, a bottom seal, and a concealed hinge assembly. The door frame includes male and female components adapted to engage each other in a rough door opening between first and second wall faces; and at least one isolation gasket adapted to be disposed between the male and female components. The compression seal is mounted to the door frame. The door slab includes an outer skin; an arched constrainment sheet inside the outer skin; a damping fill material inside the outer skin; and an acoustic insert inside the outer skin. The bottom seal is mounted to a bottom surface of the door slab such that the bottom seal is permitted to move relative to the door slab.

A plastic thermal barrier connects an inner shell and an outer shell of a window frame or a door frame. The thermal barrier includes a first part that is provided with a component for connecting it to an inner shell and an outer shell. The thermal barrier further includes a second part, whereby these parts are connected to one another in a hinged way by means of a film hinge and are provided with mutually complementary elements of a snap connector configured to fasten the two parts together.
