Insulating method and ducting configuration

Abstract

An insulation method and ducting configuration is provided. In an embodiment, an attic space of a house has at least one air duct running along a horizontal portion of said attic space. At least a portion of the at least one air duct is covered by a layer of foam insulation.

1 . A house comprising:
 a base structure comprising a heat exchanger and an air duct connected to said heat exchanger;   an attic structure above said base structure comprising at least one additional air duct connected to said heat exchanger via said air duct; and,   a layer of foam insulation substantially continuously covering at least a portion of said at least one additional air duct.   
   
   
       2 . The house of  claim 1  wherein said foam insulation is sprayed polyurethane foam. 
   
   
       3 . The house of  claim 2  wherein said foam insulation is polyurethane closed cell foam. 
   
   
       4 . The house of  claim 2  wherein said foam insulation is open cell foam. 
   
   
       5 . The house of  claim 1  wherein said foam insulation covers an entire area of said attic structure. 
   
   
       6 . The house of  claim 1  wherein said air duct and said at least one additional air duct are supply ducts. 
   
   
       7 . The house of  claim 1  wherein said air duct and said at least one additional air duct are return ducts. 
   
   
       8 . The house of  claim 1  wherein said heat exchanger is a furnace. 
   
   
       9 . The house of  claim 1  wherein said heat exchanger is an air conditioning unit. 
   
   
       10 . The house of  claim 1  wherein said foam insulation is applied to a thickness that achieves an R value of about R32. 
   
   
       11 . The house of  claim 1  wherein said foam insulation is applied to a thickness that achieves an R value of about R40. 
   
   
       12 . An attic structure comprising:
 a horizontal portion defining a ceiling in a space below said attic structure;   at least one air duct running along said horizontal portion; and,   a layer of foam insulation substantially continuously covering at least a portion of said at least one air duct.   
   
   
       13 . The attic structure of  claim 9  wherein said foam insulation is sprayed polyurethane foam. 
   
   
       14 . The attic structure of  claim 9  wherein said foam insulation covers an entire area of said attic structure. 
   
   
       15 . The attic structure of  claim 9  wherein said air duct is a supply duct. 
   
   
       16 . The attic structure of  claim 9  wherein said air duct is a return duct. 
   
   
       17 . The attic structure of  claim 1  wherein said foam insulation is applied to a thickness that achieves an R value of about R32. 
   
   
       18 . The attic structure of  claim 1  wherein said foam insulation is applied to a thickness that achieves an R value of about R40. 
   
   
       19 . A method of constructing an attic comprising:
 constructing a horizontal portion of said attic defining a ceiling in a space below said attic structure;   installing at least one air duct along said horizontal portion;   covering at least a portion of said at least one air duct with a layer of foam insulation.   
   
   
       20 . The method  claim 16  wherein said foam insulation is sprayed polyurethane foam. 
   
   
       21 . The method of  claim 16  wherein said foam insulation covers an entire area of said attic structure. 
   
   
       22 . The method of  claim 16  wherein said air duct is a supply ducts. 
   
   
       23 . The method of  claim 16  wherein said air duct is a return ducts. 
   
   
       24 . The method of  claim 16  wherein said foam insulation is applied to a thickness that achieves an R value of about R32. 
   
   
       25 . The method of  claim 16  wherein said foam insulation is applied to a thickness that achieves an R value of about R40.
