Abstract

A mold resistant exterior wall assembly incorporating a steel stud frame with an interior gypsum wall product attached to the interior of the frame and a mold resistant exterior gypsum wall product attached to the exterior of the frame forming a cavity therebetween. The joints of the exterior gypsum wall product are taped and the entire surface of the exterior gypsum wall product is coated with a liquid applied elastomeric (greater than 25% elongation) air/water barrier and vapor retarder/barrier. Once the elastomeric liquid is applied and set, rigid foam plastic insulation is applied. Exterior veneer is applied a predetermined distance from the rigid foam plastic insulation.

Claims

exact text as granted — not AI-modified
1 . A mold resistant exterior wall assembly for steel stud construction comprising: 
 a plurality of steel studs situated in parallel along a foundation, once situated establishing an inside surface and an outside surface;    a first wall member attached to the inside surface of said steel studs;    a second wall member attached to the outside surface of said steel studs;    an elastomeric component applied to said second wall member;    a rigid insulation member applied to said elastomeric component; and    exterior veneer applied a predetermined distance from said rigid insulation member.    
   
   
       2 . The mold resistant exterior wall assembly for steel stud construction of  claim 1  wherein said second wall member is mold and moisture resistant.  
   
   
       3 . The mold resistant exterior wall assembly for steel stud construction of  claim 2  wherein said second wall member comprises glass mat gypsum.  
   
   
       4 . The mold resistant exterior wall assembly for steel stud construction of  claim 3  wherein said second wall member comprises a water-resistant gypsum core surfaced with a glass mat at least partially embedded in the gypsum core.  
   
   
       5 . The mold resistant exterior wall assembly for steel stud construction of  claim 1  wherein said second wall member comprises a plurality of parallel wall member units.  
   
   
       6 . The mold resistant exterior wall assembly for steel stud construction of  claim 5  further comprising a sealant to seal said plurality of parallel wall member units.  
   
   
       7 . The mold resistant exterior wall assembly for steel stud construction of  claim 6  wherein said sealant is Universal Tape™.  
   
   
       8 . The mold resistant exterior wall assembly for steel stud construction of  claim 1  wherein said elastomeric component is a liquid applied polymer.  
   
   
       9 . The mold resistant exterior wall assembly for steel stud construction of  claim 8  wherein said elastomeric component is an asphalt polymer blend.  
   
   
       10 . The mold resistant exterior wall assembly for steel stud construction of  claim 1  wherein said rigid insulation member is a rigid foam plastic insulation.  
   
   
       11 . The mold resistant exterior wall assembly for steel stud construction of  claim 10  wherein said rigid insulation member comprises an extruded polystyrene.  
   
   
       12 . The mold resistant exterior wall assembly for steel stud construction of  claim 10  wherein said rigid insulation member comprises a polyisocyanurate.  
   
   
       13 . The mold resistant exterior wall assembly for steel stud construction of  claim 11  wherein said exterior veneer consists of brick and steel siding.  
   
   
       14 . The mold resistant exterior wall assembly for steel stud construction of  claim 12  wherein said exterior veneer consists of stucco.  
   
   
       15 . The mold resistant exterior wall assembly for steel stud construction of  claim 14  further comprising metal lath attached to said rigid insulation member.  
   
   
       16 . A method of exterior wall assembly for steel stud construction comprising the steps of: 
 situating a plurality of steel studs in parallel along a foundation establishing an inside surface and outside surface;    attaching a first wall member to the inside surface of said steel studs;    attaching a second wall member to the outside surface of said steel studs;    applying an elastomeric component to said second wall member;    applying a rigid insulation member to said elastomeric component; and    applying an exterior veneer a predetermined distance from said rigid insulation member.    
   
   
       17 . The method of exterior wall assembly for steel stud construction of  claim 16  wherein said rigid insulation member comprises polystyrene.  
   
   
       18 . The method of exterior wall assembly for steel stud construction of  claim 16  wherein said rigid insulation member comprises polyisocyanurate.  
   
   
       19 . The method of exterior wall assembly for steel stud construction of  claim 17  wherein said exterior veneer consists of brick and steel siding.  
   
   
       20 . The method of exterior wall assembly for steel stud construction of  claim 18  wherein said exterior veneer consists of stucco.
