Abstract:
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.
Abstract:
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.
