ABSTRACT:
A fire retardant panel door, including a panel door having at least one door panel and stiles and rails. The door panel includes an interior composite section formed by a first plurality of layers of intumescent materials and a first plurality of layers of fire resistant materials disposed between and laminated to a first pair of outer coverings to form a composite laminated door panel. Each of the stiles includes a first core formed of an incombustible material and a second plurality of layers of intumescent materials and a second outer covering to form a composite laminated stile. Each of the rails includes a second core formed of an incombustible material and a third plurality of layers of intumescent materials and a third outer covering to form a composite laminated rail. The first, second, and third plurality of layers of intumescent materials are activated to expand upon exposure to heat and/or fire to prevent the heat and/or fire from passing through the at least one door panel, the stiles and the rails of the panel door during a fire for at least 90 minutes. The at least one door panel is connected to the panel door by joints; and the joints include a fourth plurality of layers each comprising intumescent and fire resistant materials, wherein the fourth plurality of layers of intumescent and fire resistant materials on the joints are activated to expand upon exposure to heat and/or fire to seal the joints in order to prevent the heat and/or fire from passing through the panel door during a fire for at least 90 minutes.
