Structure of external wall or roof and external material for external wall or roofing materia

Abstract

A structure of an external wall or a roof and an external material for the external wall or a roofing material. In the structure of the external wall or the roof of a building, heat insulating and heat shielding performances are provided to a permeable layer for which dehumidifying action by the circulation of air was expected to secure high heat insulating and heat shielding performances for theexternal wall or the roof without changing the thickness of an insulator. Accordingly, when the heat insulating and heat shielding performances must not be changed, the thickness of the insulator canbe reduced less than before. The building in which an external material (11) is installed through the permeable layer (9) installed on the outside of the structure of the external wall or the roof ischaracterized in that low heat radiating sheets (8, 8a) having a low radiating performance against the heat radiation of long wavelength components are installed on the permeable layer (9) side surfaces of one or both of the external material (11) and the insulator (7).

Description

technical field [0001] The present invention relates to a building having a function of blocking heat transfer such as radiation of atmospheric heat to the room or radiation of indoor heat to the atmosphere on the outer surface side of the outer wall or roof, and particularly relates to an outer wall or a building having high heat insulation and high heat insulation performance. Structure of the roof and exterior materials for outer walls (exterior materials for outer walls) or roof paving materials (roof materials). In addition, the structure of the outer wall or the roof, or the exterior material for the outer wall or the roof paving material means that the heat insulating structure of the present invention can be commonly used for the exterior wall and the roof, as well as the exterior material for the outer wall and the roof paving material. Background technique [0002] The use of sufficient heat insulation structure in buildings such as houses is not only related to th...

AI Technical Summary

Problems solved by technology

[0006] However, it is impossible to increase the thickness of the heat insulating material only with a single-panel heat insulating material, and multiple heat insulating material plates must be stacked, so there will be an increase in construction work, an increase in material costs and construction costs, etc., resulting in a large cost increase. question
