         2 . The corner insulation block of  claim 1 , wherein the foam body comprises a closed-cell foam body. 
     
     
         3 . The corner insulation block of  claim 1 , wherein the foam body comprises a unitary piece of closed-cell foam. 
     
     
         4 . The corner insulation block of  claim 1 , wherein the plurality of cutting guides includes a first cutting guide and a second cutting guide. 
     
     
         5 . The corner insulation block of  claim 4 , wherein the first cutting guide and the second cutting guide each comprise a score line. 
     
     
         6 . The corner insulation block of  claim 5 , wherein each score line extends partially or fully about a perimeter of the foam body of the corner insulation block. 
     
     
         7 . The corner insulation block of  claim 1 , wherein the first cutting guide is spaced about 12 inches from the first end or the opposite second end of the foam body, and the second cutting guide is spaced about 12 inches from the first cutting guide. 
     
     
         8 . The corner insulation block of  claim 1 , wherein the width of the foam body is about 5.5 inches, the thickness of the foam body is about 4 inches, and the length of the foam body is about 9 feet 9 and ⅝ inches. 
     
     
         9 . The corner insulation block of  claim 1 , wherein the width of the foam body is about 5.5 inches, the thickness of the foam body is about 4 inches, and the length of the foam body is about 11 feet 9 and ⅝ inches. 
     
     
         10 . A wall system of a structure, comprising:
 one or more studs and one or more drywall backers arranged in a space between sheathing and drywall of the wall system at a corner of the structure to form a corner stud cavity; and   the corner insulation block of  claim 1  installed within the corner stud cavity.   
     
     
         11 . The wall system of  claim 10 , wherein the corner insulation block fills 90% or more of a volume of the corner stud cavity. 
     
     
         12 . The wall system of  claim 10 , wherein the corner is an exterior corner of the structure. 
     
     
         13 . The wall system of  claim 10 , wherein the corner stud cavity is formed between at least two studs and at least one drywall backer. 
     
     
         14 . The wall system of  claim 10 , wherein the foam body of the corner insulation block comprises a unitary piece of closed-cell foam that extends between a floor and a ceiling of the structure. 
     
     
         15 . The wall system of  claim 10 , wherein the structure is a residential home. 
     
     
         16 . A method for insulating a corner stud cavity of a structure, comprising:
 providing a corner insulation block, comprising:
 a foam body in the shape of a rectangular prism, the foam body including a width, a thickness, and extending a length between a first end and an opposite second end; and 
 a plurality of cutting guides at one of the first end or the opposite second end of the foam body, each of the plurality of cutting guides being spaced from an adjacent one of the plurality of cutting guides; 
   sizing the corner insulation block to the corner stud cavity; and   installing the corner insulation block in the corner stud cavity.   
     
     
         17 . The method of  claim 16 , wherein sizing the corner insulation block to the corner stud cavity further comprises:
 determining a length of the corner stud cavity;   comparing the length of the corner stud cavity to the length of the corner insulation block;   if the length of the corner insulation block is greater than the length of the corner stud cavity, selecting one of the plurality of cutting guides corresponding to the length of the corner stud cavity; and   cutting the corner insulation block along the selected one of the plurality of cutting guides.   
     
     
         18 . The method of  claim 17 , wherein the plurality of cutting guides include a first cutting guide and a second cutting guide, the second cutting guide being spaced about 12 inches from the first cutting guide, the method further comprising:
 selecting one of the first or the second cutting guides corresponding to the length of the corner stud cavity; and   cutting the corner insulation block along the selected first or second cutting guide.
