A first structural plywood 11 which is an existing base is fixed to the first rafter 10 with nails (not shown) or the like. The first structural plywood 11 is made of a long-fiber nonwoven fabric in which ultrafine fibers obtained by continuously spinning polyethylene are formed into a sheet shape and the fibers are bonded together at high temperature and high pressure. The sheet 12 having the function of fendering is fixed by a thin nail or stapler (not shown). A second rafter 13 is fixed to the sheet 12 with nails (not shown) or the like. In a state of being fixed to the sheet 12 and the second rafter 13, a cushioning material 15 composed of an extruded polystyrene foam heat insulating plate or the like and having a heat insulating function is attached. In such an attached state, a heat insulating material 16 composed of an extruded polystyrene foam heat insulating plate or the like is attached to the cushioning material 15 so as to form the ventilation layer 14. A second structural plywood 17 is fixed to the second rafter 13 and the heat insulating material 16 with nails (not shown) or the like.

For this reason, most of the radiant heat from sunlight is blocked by the heat insulating material 16, and this radiant heat is released from the first ventilation layer 14 to the outside of the roof 2. Since the radiant heat is not accumulated on the roof 2 due to the release of the radiant heat, the indoor temperature is not affected by weather conditions.

For this reason, most of the radiant heat due to sunlight is blocked by the heat insulating material 16, and this radiant heat is released to the outside of the roof 2 from the first air layer 14A and the second air layer 14B. Since the radiant heat is not accumulated on the roof 2 due to the release of the radiant heat, the indoor temperature is not affected by weather conditions. In this case, since the air layer is formed in two places in the second embodiment of the present invention, the efficiency of releasing radiant heat to the outside is improved as compared with the first embodiment.

The sheet 12 having the function of fendering is fixed by a thin nail or stapler (not shown). A second rafter 13 is fixed to the sheet 12 with nails (not shown) or the like. In a state of being fixed to the sheet 12 and the second rafter 13, a heat insulating material 16 composed of an extruded polystyrene foam heat insulating plate or the like is attached so as to form a ventilation layer 14.

In the third embodiment of the present invention having the above configuration, the ventilation layer 14 is formed by the second rafter 13, the heat insulating material 16, and the second structural plywood 17. For this reason, most of the radiant heat due to sunlight is blocked by the heat insulating material 16, and this radiant heat is released to the outside of the roof 2 from the first air layer 14A and the second air layer 14B. Since the radiant heat is not accumulated on the roof 2 due to the release of the radiant heat, the indoor temperature is not affected by weather conditions.

A first structural plywood 11 which is an existing base is fixed to the first rafter 10 with nails (not shown) or the like. The first structural plywood 11 is made of a long-fiber nonwoven fabric or the like in which ultrafine fibers obtained by continuously spinning polyethylene are formed into a sheet shape and the fibers are bonded together at high temperature and high pressure. The sheet 12 having the function of fendering is fixed by a thin nail or stapler (not shown). A second rafter 13 is fixed to the sheet 12 with nails (not shown) or the like.

In the fourth embodiment of the present invention having the above-described configuration, the ventilation layer 14 is formed by the moisture-proof / anti-mold sheet 12, the cushioning material 15, and the heat insulating material 16. For this reason, most of the radiant heat due to sunlight is blocked by the heat insulating material 16, and this radiant heat is released from the first air layer 14 to the outside of the roof 2. Since the radiant heat is not accumulated on the roof 2 due to the release of the radiant heat, the indoor temperature is not affected by weather conditions. Moreover, since the heat insulating material 20 having foamed polystyrene, self-digestibility, etc. is used as a roofing material, the prevention of the occurrence of wrinkles due to the occurrence of condensation due to the moisture and corrosion resistance of the housing becomes significant.

For this reason, most of the radiant heat from sunlight is blocked by the heat insulating material 16, and the radiant heat is released to the outside of the roof 2 by the air layer 14. Since the radiant heat is not accumulated on the roof 2 due to the release of the radiant heat, the indoor temperature is not affected by weather conditions. Moreover, compared with the structure in the said Example 1-the said Example 4, in this Example 5, since the sheet | seat for moisture prevention / rust prevention is not used, it is cheap.

Since the radiant heat is not accumulated on the roof 2 due to the release of the radiant heat, the indoor temperature is not affected by weather conditions. Moreover, since the heat insulating material which has a polystyrene foam, self-digestibility, etc. is used as a roofing material, the prevention | occurrence | production prevention of a wrinkle by generation | occurrence | production of dew condensation etc. becomes remarkable by the moisture-proof / corrosion prevention of a housing.
