CONSTRUCTION METHOD OF REINFORCING ATTIC HEAT INSULATION WITHOUT ATTIC VENTILATION OF DWELLING HOUSE TO IMPROVE HEAT INSULATION OF ROOF PART USING ACCUMULATED SNOW ON ROOF FLOOR INTEGRALLY AS HEAT INSULATION LAYER AND DISCHARGE HUMIDITY AND HOT AIR BY VINYL CHLORIDE PIPE PASSING FROM ATTIC TO ROOF FLOOR

摘要

PROBLEM TO BE SOLVED: To achieve the invention utilizing snow, which definitely comes in winter in the Northern area, as a heat insulation layer when accumulated on a roof floor, and therefore relating to the structure of the roof part of a dwelling house, a heat insulation method, and countermeasure for dew condensation; providing a technology to utilize natural snow for heat insulation, thereby saving heating cost in dwelling house and reducing emission of carbon dioxide.;SOLUTION: Since the conventional dwelling houses employ attic ventilation, accumulated snow 13 on a roof floor could not be utilized for heat insulation. Furthermore, cold air for ventilation flows in the attic decreased the heat insulation effect. The attic is tightly closed without the ventilation in the attic of the dwelling house and the heat insulation is applied thereto, so as to be a heat insulation layer integral with the accumulated snow 13 on the roof floor. For preventing dew condensation, air with high humidity is discharged through a pipe 14 passing from the attic to the roof floor. The pipe 14 is utilized also in Summer.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
