However, in the case of the above-mentioned wall structure, work efficiency is poor in combination with the fact that the structure in which the furring strip is always hit is troublesome in construction and requires a high degree of skill. Feng shui sheet is easy to tear, and gaps are likely to be created in the stack. In addition, since the windproof sheet is paper, it has a side that makes it difficult to perform heat insulation when inserting a heat insulating material. There is a gap in the connection part of the windbreak sheet, and rainwater often enters due to laceration of the windbreak sheet and unsuccessful stacking, which easily causes corrosion of columns, studs and furring strips, and internal condensation. In the case of the structure, the air M in the space between the windbreak sheet b and the outer wall material d rises to the attic or the like in order to hit the furring strip in the vertical direction, but in the case of the vertical structure, as shown in FIG. Hit in the direction Because it is, air M is furring strips c
The effect of ventilation cannot be obtained due to the presence of the heat sink, and the wall body becomes a hotbed for molds and mites, eventually leading to the decay of the building.In extreme cases, heat insulation of a single gypsum board There are also constructions where only waterproof and airtight performance can be obtained.
