In recent years, so-called new construction materials such as plywood boards and gypsum boards have been used as building materials for houses and the like, and in particular, their use as wall covering materials has increased. By the way, walls made of gypsum board or plywood have poor insulation effects, so
Usually, a heat insulating material such as glass wool is inserted between the inner wall and the outer wall.

止している。 By the way, in walls with this type of structure, water accumulates in the glass wool layer, causing the problem of corrosion of wooden parts such as pillars, so oil-impregnated paper (asphalt/felt) or a polyethylene layer is usually installed between it and the outer wall. Insert waterproof paper etc.
Glass wool wrapped in aluminized polyethylene is used to prevent the glass wool itself from absorbing moisture.

However, if waterproof paper is simply inserted between the outer wall and the glass wool, there is a problem that when the outside temperature drops, moisture that reaches the waterproof paper from the inner wall will condense and gradually accumulate in the glass wool layer. be. In addition, when using glass wool wrapped in aluminized polyethylene, the glass wool itself does not have the problem of moisture accumulation, but it is not water vapor permeable and indoor moisture cannot escape through the wall, so There is a problem with condensation.
本考案の目的は、上記防水紙と同様に外気から
