20110040401 | System, Method and Apparatus for Producing Fire Rated Doors - The present invention provides a system, method and apparatus for producing fire rated doors having added strength, better finishing and low cost manufacturing flexibility. The fire rated doors are made from two panels “sandwiched” together. An optional interior layer (e.g., fire resistant material, lead sheeting, steel or Kevlar) can be added between the door panels for various purposes. Splines, stiles or sticks are inserted in longitudinal channels in the door panels to provide assistance in aligning the door panels and greater hardware holding strength. An intumescent banding material concealed by a banding material around the perimeter of the door seals the door within its frame during a fire. The door design and the automated manufacturing process provide greater design choice, reduced cost and faster fabrication. | 02-17-2011 |

20130086858 | FIRE RATED DOOR CORE - A core for a fire rated door includes an extruded fire resistant material, a filler material and a panel. The extruded fire resistant material has a first raised portion, a second raised portion and a lower portion that extends from a first end to a second end. The first raised portion has a first thickness and a first width that extends from the first side to the lower portion. The lower portion has a second thickness. The second raised portion has the first thickness and a second width that extends from the second side to the lower portion. The filler material is disposed above the lower portion of the extruded fire resistant material between the first raised portion and the second portion. The panel is attached to the first raised portion and the second raised portion of the extruded fire resistant material and covers the filler material. | 04-11-2013 |

20150086769 | GYPSUM COMPOSITES USED IN FIRE RESISTANT BUILDING COMPONENTS - A composite product includes gypsum in an amount of 60 to 90% by weight, fibers in an amount of 1.5 to 26% by weight substantially homogeneously distributed through the composite, and a rheology-modifying agent in an amount of 0.5 to 6% by weight. The composite is caused or allowed to cure to form a cured composite. The cured composite is a fire resistant component used in a fire-rated door core, a fire-rated door or a fire-rated building panel. The fire resistant component may include a building panel, a door panel, a door core, a door rail, a door stile, a door lock block, a door border, or a door insert. | 03-26-2015 |
