Abstract:
A fire rated glass door assembly configured to inhibit the spread of fire and smoke in the region of a wall of a building, said fire rated glass door assembly comprising:a first side and a second side being disposed opposite said first side; a fire protection partition of a building; a door jamb; said door jamb comprising a substantially contiguous and unitary frame structure; said door jamb being disposed in a stationary manner in said fire protection partition of a building; said door jamb comprising a first side and a second side disposed opposite said first side; said door jamb comprising a material to provide said door jamb with a fire rating and thus with the capability to withstand fire a predetermined time with a predetermined fire temperature on said first side of said door jamb and a predetermined maximum temperature on said second side of said door jamb; at least one door leaf; said at least one door leaf comprising a first side and a second side disposed opposite said first side; said first side of said at least one door leaf comprising a first glass pane; said second side of said at least one door leaf comprising a second glass pane; said glass panes of said at least one door leaf being configured to provide said at least one door leaf with a fire rating and thus with the capability to withstand fire a predetermined time with a predetermined fire temperature on said first side of said at least one door leaf and a predetermined maximum temperature on said second side of said at least one door leaf; said at least one door leaf comprising a substantially contiguous and unitary frame structure; said at least one door leaf being configured and disposed to be mobile in reference to said fire protection partition of a building; said at least one door leaf at least partially enclosed by said door jamb; said at least one door leaf comprising a compartment; said compartment being disposed between said first side and said second side of said at least one door leaf and to extend over a substantial portion of said at least one door leaf; a material being disposed in said compartment; said material in said compartment comprising a transparent foam to impart to said door assembly a fire rating and thus with the capability to withstand fire a predetermined time with a predetermined fire temperature on said first side of said door assembly and a predetermined maximum temperature on said second side of said door assembly to thus enhance the fire rating capability of said fire rated door assembly to withstand fire and smoke; at least one of: said door jamb and said at least one door leaf comprising a synthetic/plastic material; said synthetic/plastic material comprising a glass fiber reinforced plastic material; said glass fiber reinforced plastic material comprising: a support material comprising glass fiber rovings; said glass fiber rovings being arranged in axial/transverse direction; at least one of: said door jamb and said at least one door leaf comprising a frame; said frame comprising a profile structure; said profile structure comprising a synthetic/plastic material; said profile structure, when considered in a radial direction, being reinforced with a glass fiber complex; said glass fiber complex comprising a molded and heat-hardened glass fiber complex; said glass fiber complex comprising glass fibers impregnated with a resin matrix; and said resin matrix comprising at least one of: unsaturated polyester resin; a hardener to harden said resin; at least one accelerator to accelerate hardening of said resin; additives to augment said resin; at least one coloring agent to impart color to said resin; and at least one fire retarding filler to render said profile structure fire retardant.
