Description

TECHNICAL FIELD The present invention relates to a ventilation material, an exterior wall ventilation construction method, and an exterior wall ventilation structure using the same. The present invention relates to a ventilation material suitable for , an exterior wall ventilation construction method using the same, and an exterior wall ventilation structure.

The standard construction method for siding is the exterior wall ventilation method, which aims to improve the durability of houses. This exterior wall ventilation method creates a ventilation layer between the moisture-permeable waterproof sheet and the exterior wall material, allowing the moisture inside the wall to escape from the moisture-permeable waterproof sheet into the ventilation layer and out to the outside. is. By releasing the moisture inside the wall to the outside in this way, it is possible to reduce dew condensation inside the wall, which is advantageous in that the durability of the building can be improved.

In order to form and secure a ventilation layer in this exterior wall ventilation construction method, vertical furring strips or horizontal furring strips are nailed to columns and studs, and siding is fastened to the horizontal furring strips (ventilation furring strips). When the siding is vertically laid, the base furring strip is the horizontal furring strip 35 (see FIG. 5). It is necessary to make it continuous and provide a watermark (ventilation gap) 36 .

In addition, in order to ensure ventilation in the ventilation layer, it is necessary to provide an air inlet at the lower end of the siding and an air outlet at the upper end. The desire to hold the siding firmly in place, such as when a person is working, may result in the use of a series of siding fasteners that do not have a watermark, especially at the top edge. Naturally, in that case, even if the horizontal furring strip 35 with the openwork 36 in the middle portion is used, the air permeability is hindered and the role of the ventilation layer cannot be fulfilled.

Further, whether the holding force of nails, screws, etc. for fastening the siding (hereinafter referred to as "nail holding force") is borne only by the horizontal furring strips 35, or the pillars or pillars that penetrate through the horizontal furring strips 35 and serve as bases therefor. It is also necessary to consider whether the studs will also bear the burden.
