Abstract: A fire stop system with a pass through device is installed in a structural opening. The fire stop system includes a split pipe, a foam wall gasket and an annulus plate. The split pipe includes a first end and a second end. The first end and the second end have an intumescent material installed thereon to seal the split pipe when the split pipe is exposed to elevated temperatures. The foam wall gasket is installed around the split pipe adjacent the structural opening. The foam wall gasket forms a contour to the structural opening blocking air flow between the split pipe and the opening. The annulus plate covers the foam wall gasket and is installed around the split pipe at the structural opening.

Abstract: A fireproof resin sash that is usable in fire zones or the like is provided, regarding which fireproof performance is easily imparted to a general non-fireproof resin sash without modification of the structure thereof.

Abstract: A thermally insulated structural member for a door or window includes a metal frame and a plastic insulation bar. The plastic insulation bar is formed from a thermoplastic composition that includes about 55 to about 95 weight percent of a compatibilized polyamide-poly(arylene ether) composition, and about 5 to about 45 weight percent of hollow glass beads. The hollow glass beads used in the thermoplastic composition have a volume-average diameter of about 20 to about 60 micrometers, a true density of about 0.3 to about 0.5 grams per milliliter, and an isostatic crush strength of about 30 to about 60 megapascals. The thermoplastic composition includes less than 5 weight percent of fibrous reinforcement. The thermally insulated structural member provides improved thermal insulation compared to structural member utilizing fiberglass-reinforced plastic insulation bars.

The prefabricated angular flange includes a first flange leg to be secured to the duct and a second flange leg with a sealing member preferably of flexibly resilient foam which could be intumescent attached to a surface of the second leg such that when the first flange leg is secured to the duct the second flange leg can be urged against the structural panel extending therearound with the sealing member positioned between the structural panel and the second flange leg and sealing the annulus.

Abstract: An angular flange for reinforcing and firestopping in the annulus between a structural panel such as a wall, ceiling or floor and a duct extending therethrough. The prefabricated angular flange includes a primary angular flange leg to be secured to the duct and a secondary angular flange leg approximately perpendicularly oriented relative thereto. Each flange includes a sealing member of flexible intumescent paper positionable therealong to facilitate firestopping therebetween. The sealing member preferably including two panels at an obtuse angle with respect to one another and being flexible to become approximately perpendicular with respect to one another responsive to securement of the angular flange to the duct and the surrounding structural panel. One or more uniquely designed corner brackets can be included for mounting the adjacently positioned angular flanges with respect to one another selectively.

Abstract: A fire door designed to slow the progress of a fire in a dwelling or commercial building. More particularly, a fire door having one or more vertical stiles that include a layer of intumescent material.

Abstract: A method, and the resultant apparatus, for designing a fire resistant structural beam, such as a computer-aided design of a fabricated steel beam having an intumescent coating material, by obtaining a number of values for a number of physical parameters of the structural beam, including reading temperature information that comprise empirical information derived from heating a structural beam and a number of temperatures at a number of locations.

Abstract: A structure including a first building unit; a second building unit; and a confined space between the building units. The units may be oriented horizontally or vertically. In an embodiment, the confined space is substantially filled with an organic containing material having a verified minimum installed density of greater than about ½ pound per cubic foot. In an embodiment, the confined space is substantially filled with an organic containing material comprising greater than about 20 percent organic material. Also in an embodiment, the structure comprises a structure connecting the confined space to the first unit and the second unit. The confined space provides improved fire, thermal and acoustic resistance properties.

Abstract: The instant invention includes a flexible fire-resistant thermally insulated composite structure designed in some embodiments to pass through an opening. The structure may be self-supporting due to the stiffness of various layers, and battens may contribute to the self-supporting capacity of the structure. The flexible composite structure may have a collapsed transit configuration, allowing the structure to be compressed to more easily pass it through an opening, a rotable attachment to allow the structure to rotate away from the opening, and a releasable attachment for attaching the structure around an opening periphery. In another embodiment, the structure may also include a bottom and such a structure could provide shelter in conditions ranging from ambient environmental conditions to the extreme heat of certain fires. The insulative structures of the instant invention are not limited to embodiments designed to rest on generally horizontal surfaces.

Abstract: The invention relates to a fireproofing element comprising a fireproof glazed element (1) which forms a window or door leaf (8). A bulkhead frame (3) is arranged around the door leaf (8), inserted in the building (2). A deformable component (28) is built in between the bulkhead frame (3) and the building (2). At least one telescopic element (15) is arranged between a lateral edge (10) of the door leaf (8) and the bulkhead frame (3). Said telescopic element (15) is displaceable relative to the bulkhead frame (3) in the direction of the arrows (20). The telescopic element (15) can compensate for changes in the joint (50) between the door leaf (8) and the bulkhead frame (3) and/or also seal said joint (50). Changes in length as a result of heating of the components during a fire can thus be accommodated and the door leaf (8) and fireproofing glazed element (1) hence not destroyed.

Abstract: A method for fabricating muntin grid pieces includes steps that attach a pair of material strips to opposed edges of the muntin bar element. The material strips may be provided in side-by-side strips that may be separated an simultaneously applied to the opposite sides of the muntin bar element. The connection between the material strips and the muntin bar element may be made with an adhesive or a mechanical connection. The method allows the material strips to be connected to the muntin grid pieces before the muntin grid pieces are assembled into a muntin bar grid for a window.
