Claims (1)

[Scope of claim for utility model registration] (1) On the indoor side of the exterior wall materials and roof materials of buildings,
It is formed by separating an outer ventilation layer and an inner ventilation layer,
and the insulation material is stretched in the plane direction so that the outer ventilation layer and the inner ventilation layer do not directly communicate with each other, and the inner ventilation layer constantly communicates with the attic space and the underfloor space, This building includes an under-floor ventilation opening that appropriately communicates outside air and the under-floor space with an under-floor opening/closing damper, and an under-ridge ventilation opening that appropriately communicates the outer ventilation layer and the inner ventilation layer with an under-ridge opening/closing damper near the ridge. A heat insulating ventilation structure for a building, characterized in that the structure is formed by: (2) The insulating ventilation structure for a building according to claim 1, wherein at least one of the lower end and the upper end of the outer ventilation layer is open to the outside air. (3) The insulation ventilation structure for a building according to claim 1, wherein the outer ventilation layer and the inner ventilation layer communicate with each other at or near a foundation.
