Abstract:
PROBLEM TO BE SOLVED: To provide a heat insulation structure and a heat insulation method for a building, capable of suppressing or preventing internal dew condensation on an existing external wall even if an external wall is newly mounted on the outdoor side of the existing external wall.SOLUTION: Vent holes 82 are provided in a cladding 56 in an existing external wall 12, and a plurality of ventilation furring strips 84 are arranged along a height direction of a building 10 on the outdoor side of the cladding 56. A heat insulation material 74 is arranged between the adjacent ventilation furring strips 84, and a cladding 88 in a new external wall 14 is mounted on the ventilation furring strips 84. A vent layer 76 in the external wall 12 and a vent layer 90 in the external wall 14 can be communicated with each other, and air in the vent layer 76 in the external wall 12 can be guided to the vent layer 90 in the external wall 14 through the vent holes 82 provided in the cladding 56, thus allowing moisture in the external wall 12 to escape to an outdoor 52 side via the vent layer 90.
