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.

Claims

exact text as granted — not AI-modified
1 . A structure comprising:
 (a) a first building unit;   (b) a second building unit; and   (c) a confined space between the building units, the space substantially filled with an organic containing material having a minimum installed density of greater than about ½ pound per cubic foot,   whereby said confined space provides improved fire, sound, or thermal resistance and combinations thereof.   
     
     
         2 . The structure according to  claim 1 , further including a structure connecting the confined space to the first unit and the second unit. 
     
     
         3 . The structure according to  claim 1 , wherein the confined space is a fire resistance rated, confined space. 
     
     
         4 . A confined space for a structure, the structure comprising an interior support structure and an outer membrane on each side of the interior support structure, the confined space filled with an organic containing material comprising greater than about 20 percent organic material, whereby the confined space provides improved fire, sound, or thermal resistance and combinations thereof. 
     
     
         5 . The confined space according to  claim 4 , wherein the organic containing material is selected from the group consisting of fibrous material, granular material, pellet material, agglomerated material, aggregated material, closed cell foam, open cell foam, fire retardants, binders and mixtures thereof. 
     
     
         6 . The organic containing material according to  claim 4 , wherein the organic containing material may include an inorganic material. 
     
     
         7 . The confined space according to  claim 6 , wherein the inorganic material is selected from the group consisting of fiberglass, rock wool, pearlite, mineral wool, asbestos, cementitious materials, fire retardants, binders and mixtures thereof. 
     
     
         8 . The confined space according to  claim 4 , wherein the organic containing material is a low-conductivity material. 
     
     
         9 . The confined space according to  claim 8 , wherein the low-conductivity material is a thermally resistant material. 
     
     
         10 . The confined space according to  claim 8 , wherein the low-conductivity material is an acoustically transmission resistive material. 
     
     
         11 . The confined space according to  claim 8 , wherein the low-conductivity material is an electrically non-conductive material. 
     
     
         12 . A structure comprising:
 (a) a first building unit;   (b) a second building unit;   (c) a confined space between the building units, the confined space substantially filled with an organic containing material comprising greater than about 20 percent organic material; and   (d) a structure connecting the confined space to the first unit and the second unit,   whereby the confined space provides improved fire, sound, or thermal resistance and combinations thereof.   
     
     
         13 . The structure according to  claim 12 , wherein the structure includes an upper structure attached to the top edge of the confined space and a lower structure attached to the bottom edge of the confined space. 
     
     
         14 . The structure according to  claim 13 , wherein the upper structure is a floor assembly, roof truss, or gable assembly. 
     
     
         15 . The structure according to  claim 13 , wherein the lower structure is a foundation, base, or floor. 
     
     
         16 . The structure according to  claim 12 , wherein the first building unit is an occupiable space. 
     
     
         17 . The structure according to  claim 16 , wherein the occupiable space is residential. 
     
     
         18 . The structure according to  claim 17 , wherein the residential occupiable space is a town home. 
     
     
         19 . The structure according to  claim 17 , wherein the residential space is a first floor. 
     
     
         20 . The structure according to  claim 12 , wherein the second building unit is an occupiable space. 
     
     
         21 . The structure according to  claim 20 , wherein the occupiable space is residential. 
     
     
         22 . The structure according to  claim 21 , wherein the residential occupiable space is a town home. 
     
     
         23 . The structure according to  claim 21 , wherein the residential occupiable space is a second floor.
