ことが考えられる。When a siding material is used as an exterior material, a breathable waterproof sheet is attached to the outer surface side of a structural material such as a pillar, a stud and a transverse member, and the outer surface of the breathable waterproof sheet is used. A wall structure is attached to the structural material on the side, and an outer wall material (siding material) is attached to the outer surface of the body material. Also in this case, even when dew water is generated in the space (inside the wall) between the outer wall material and the waterproof sheet as in the above-described conventional example, the inside of the wall is air-dried, thereby improving the durability of the structural material. It is conceivable to make it happen.

By providing a large number of the air communication holes in the plate-like material, even if the plate-like material is attached, the ventilation opening ratio with respect to the entire side surface of the receiving material is hardly reduced. Further, by making the plate-like material a non-combustible material such as glass fiber, it is possible to prevent the flame from burning up. Therefore, insect repellency and fire resistance can be improved while maintaining the air permeability inside the wall.

上させることができる。According to the present invention, air permeability in the space between the exterior material and the waterproof sheet can be easily and stably secured, and the insect and fire protection effects can be improved. In addition, when the notch recess is formed on the waterproof sheet side of the receiving material, the waterproof sheet cannot be uniformly pressed without a plate-like object, so if strong wind blows into the notch recess, the notch may be formed in the recess. The waterproof sheet is deflected, resulting in deterioration of air permeability. However, according to the present invention, the waterproof sheet can be uniformly pressed by the waterproof sheet side end surface of the plate-like object, and the strong wind is weakened by the plate-like object, so that the waterproof sheet does not float up in the notch recess. Good air permeability can be maintained. Therefore, even if the ventilation section is formed on the waterproof sheet side of the receiving material, it is possible to prevent the waterproof sheet from floating inside the ventilation section and secure the air permeability, thereby reliably improving the durability of the structural material and the like. Can be done.
