An isometric view of fire door construction (60) comprising gypsum fiberboard panels (62) having a density of at leat 60 lbs/ft3, a flexural strength of at least 30 lbs (1/2) inch thick material), and a screw holding capacity of at least 400 lbs. Said panel has a composition comprising 65 wt % to 90 wt % gypsum dihydrate, 7 wt % to 30 wt % paper fiber, and a performance booster selected from inorganic fiber, clay, vermiculite, and binder polymer. The honeycomb structure (66) is surrounded at the door perimeter by gypsum fiberboard edge banding (65) with a preferred density of 65 lbs/ft3 and a screw holding capacity of at least 600 lbs/ft3.

Vue isométrique d'une construction (60) de porte coupe-feu, comprenant des panneaux (62) de fibres de gypse ayant une densité d'au moins 60 livres par pied cube, une résistance à la flexion d'au moins 30 livres (matériau d'une épaisseur de 1/2 pouce), ainsi qu'une capacité de maintien de vis d'au moins 400 livres. Ledit panneau a une composition comprenant 65 à 90 % en poids de dihydrate de gypse, 7 à 30 % en poids de fibre de papier, et un agent augmentant l'efficacité choisie parmi une fibre inorganique, de l'argile, la vermiculite, ainsi qu'un polymère de liaison. La structure (66) en nid-d'abeilles est entourée au niveau du périmètre de la porte, par un bandage (65) de bordure de panneau de fibres en gypse, d'une densité préférée de 65 livres par pied cube, et d'une capacité de maintien de vis d'au moins 600 livres par pied cube.
