A fire rated door utilizing a pair of frame members each having cases forming opposing open chambers. The open chambers are filled with fire resistant material and include structural plates that do not contact the cases. Holders attach to the cases support a fire resistant glazing unit. The fire rated door may be clad around the pair of frame members.

A fire door includes an intermediate member formed in the shape of a plate and arranged between a first plate member and a second plate member; a first heat insulating material arranged between the first plate member and the intermediate member; a second heat insulating material arranged between the second plate member and the intermediate member; a first coupling member for coupling the first plate member and the intermediate member, arranged so as to extend through the first heat insulating material; and a second coupling member for coupling the second plate member and the intermediate member, arranged so as to extend through the second heat insulating material. The first coupling member is arranged so as to be spaced away from both of the second plate member and the second coupling member. The second coupling member is arranged so as to be spaced away from the first plate member, and the first plate member and the second plate member are arranged so as to be spaced away from each other.
