  • Patent number: 11851942
    Abstract: An acoustic door assembly having 1¾? thickness, a sound transmission class (STC) rating greater than 50, UL10C 20-minute fire rating, and constructed without sheet metal or lead. In an embodiment, the door assembly includes a frame housing a decoupled internal core sandwiched between two mass-loaded vinyl outer faces. The internal core includes a multi-layering of low-density layers for absorbing high-frequency noise, damping layers of mass-loaded vinyl for absorbing low-frequency noise, and a flame-retardant layer. The outer faces are a multi-layered assembly coupled to a frame of the door assembly and in contact communication to the internal core, the outer faces having layers of mass-loaded vinyl, plywood, high-density fiberboard, and a veneer.

  • Patent number: 8573357
    Abstract: An acoustical door comprising an inner core assembly includes a spacer frame having a first set of spacer strips extending along a first direction and a second set of spacer strips extending along a second direction. The inner core assembly further includes first and second core layers positioned within the spacer frame. The second core layer is constructed of a material dissimilar from the first core layer. The acoustical door further comprises a multi-layer skin spaced apart from the inner core assembly. The multi-layer skin includes a sheet constructed of lead. The acoustical door also includes a spacer coupling the multi-layer skin and the inner core assembly around a mutual periphery. An air space is defined within the mutual periphery and between the multi-layer skin and the inner core assembly such that the multi-layer skin is configured to flex independent of the inner core assembly.

  • Patent number: 6112496
    Abstract: In a composite metal and wood door, two metal panels (10,32) that are aligned in parallel relationship are secured together by connectors (56-70, 88-102). Panels (10,32) and connectors (56-70, 88-100) cooperate to define channels (122-136) that receive corresponding members (138-148) that are made of a composite material. Metal panels (10,32) and composite members (138-148) are covered by wooden panels (178, 180).

  • Patent number: 5816017
    Abstract: A fire retardant door having a vertical latch stile extending the length of the stile for receiving the elements of a concealed vertical rod exit device therein along with an expanding, fire resistant material, preferably an intumescent compound, for sealing the opening when subjected to heat. The vertically reciprocating exit device rods disposed in the opening are operably connected to bolts disposed in the end of the stile openings, the bolts moveable in response to movement of the vertically reciprocating element from a retracted position within the door edge opening to an extended position to engage the door frame. The composition of the door and arrangement of the exit device elements is selected for a high fire rating, and preferably includes a wooden outer layer provided on each of the major faces of the door.
