Patent number: 8069625Abstract: Fire resistant door, glazing, and mullion frames include intumescent material at least partially embedded in the frame adjacent the door or glazing. Trim materials are positioned over the intumescent material to prevent tampering with and damage to the intumescent material while improving the aesthetic appearance of the frame. The jamb trim has a thickness that allows heat to be transmitted to the intumescent material in the event of a fire so that the intumescent material will expand and fill a clearance space between the frame and the door or glazing. The expanded intumescent material retards the passage of heat and, by sealing the clearance space, inhibits the transmission of smoke, flames and gases from one side of the door or glazing to the other. After expanding, the intumescent material will char and solidify, which may provide an added benefit of structural support for the door or glazing.Type: GrantFiled: January 21, 2009Date of Patent: December 6, 2011Assignee: Washington Hardwoods Co., LLCInventors: Jim Harkins, John Gaydos

Publication number: 20070245685Abstract: A doorframe kit includes a head jamb for installation over a top portion of a doorway and a vertical jamb adapted to be joined to the head jamb and extend along a surface of a wall adjacent the doorway. The doorframe kit may include an adjustable spacer having a shaft adjustably engaged with a retaining member. The retaining member may be fixedly mounted to the vertical jamb at an adjustment location spaced below the head jamb. The shaft may be selectively movable relative to the retaining member to project outwardly from the vertical jamb and bear against the surface of the wall, when in use, to thereby define a standoff distance between the vertical jamb and the wall at the adjustment location. Inserting a tool into an access opening formed in the vertical jamb allows the tool to drive the adjustable spacer outwardly thereby increasing the standoff distance.Type: ApplicationFiled: March 29, 2007Publication date: October 25, 2007Applicant: Washington Hardwoods Co., LLCInventor: John Gaydos

Patent number: 7059092Abstract: Door and glazing frames include intumescent material positioned in a dado that is formed in a jamb side surface. Trim materials are positioned over the intumescent material to improve the appearance of the frame and to prevent tampering with and damage to the intumescent material. The jamb trim is preferably made of a cut hardwood panel having a thickness that allows heat to be transmitted to the intumescent material in the event of a fire so that the intumescent material will expand and fill a clearance space between the frame and the door or glazing. The expanded intumescent material inhibits the transmission of smoke and heat between the door and door frame. After expanding, the intumescent material will char and solidify, which may provide an added benefit of structural support for the door and or glazing.Type: GrantFiled: February 25, 2003Date of Patent: June 13, 2006Assignee: Washington Hardwoods Co., LLCInventors: Jim Harkins, John Gaydos
