Wall system and method of forming same

Abstract

A wall system is provided, comprising: a frame comprising at least one frame member; a cladding material disposed at an external side of the frame member; a drainage mat disposed between the frame member and the cladding material; and an insulation layer disposed at an internal side of the drainage mat.

1 . A wall system, comprising:
 a frame comprising at least one frame member;   a cladding material disposed at an external side of the frame member;   a drainage mat disposed between the frame member and the cladding material; and   an insulation layer disposed at an internal side of the drainage mat.   
   
   
       2 . The wall system according to  claim 1 , further comprising an interior sheathing layer arranged at an internal side of the frame member. 
   
   
       3 . The wall system according to  claim 2 , wherein the interior sheathing layer and the insulation layer are arranged such that a space is present therebetween. 
   
   
       4 . The wall system according to  claim 1 , wherein the insulation layer comprises foam, fiberglass, cellulose or combinations thereof. 
   
   
       5 . The wall system according to  claim 1 , wherein the frame comprises a plurality of vertically arranged frame members. 
   
   
       6 . The wall system according to  claim 5 , further comprising a fire blocking strip disposed between two adjacent frame members. 
   
   
       7 . The wall system according to  claim 1 , wherein the drainage mat is in contact with the cladding material. 
   
   
       8 . The wall system according to  claim 1 , wherein the drainage mat comprises a porous, spunbond, non-woven material. 
   
   
       9 . The wall system according to  claim 1 , wherein the insulation layer comprises closed cell urethane foam. 
   
   
       10 . The wall system according to  claim 1 , further comprising at least one cladding material support device attached to the at least one frame member and the cladding material. 
   
   
       11 . The wall system according to  claim 10 , wherein the drainage mat is attached to the at least one cladding material support device, and wherein the at least one cladding material support device comprises a stop for maintaining the position of the drainage mat. 
   
   
       12 . A method of forming the wall system of  claim 1 , comprising:
 arranging the drainage mat at an external side of the frame member;   arranging the cladding material at an external side of the drainage mat; and   arranging the insulation layer at an internal side of the frame member.   
   
   
       13 . The method according to  claim 12 , further comprising arranging an interior sheathing layer at an internal side of the frame member. 
   
   
       14 . The method according to  claim 13 , wherein the interior sheathing layer is arranged such that a space exists between the interior wall sheathing layer and the insulation layer. 
   
   
       15 . The method according to  claim 12 , wherein the insulation layer comprises foam, fiberglass, cellulose or combinations thereof. 
   
   
       16 . The method according to  claim 12 , wherein the frame comprises a plurality of vertically arranged frame members. 
   
   
       17 . The method according to  claim 16 , wherein the wall system further comprises a fire blocking strip disposed between two adjacent frame members. 
   
   
       18 . The method according to  claim 12 , wherein the drainage mat is in contact with the cladding material. 
   
   
       19 . The method according to  claim 12 , further comprising attaching at least one cladding material support device to the at least one frame member and the cladding material. 
   
   
       20 . The method according to  claim 19 , wherein the drainage mat is attached to the at least one cladding material support device, and wherein the at least one cladding material support device comprises a stop for maintaining the position of the drainage mat.
