Description

  The present invention relates to a ventilation wall structure having a moisture exhaust function, an exhaust function, a dew condensation prevention function, a waterproof function, a heat shield function, a heat insulation function, and the like.

  When the wall is hermetically sealed, there is no place for water vapor to escape, and condensation occurs on the back of the outer wall material or on the wall if the outside air temperature is low. Therefore, a method of providing an air layer with a thickness of about 20 mm between the outer wall material and the housing in order to discharge water vapor in the wall to the outside air to prevent internal dew condensation and to discharge moisture that has soaked into the base and pillars to the outside air. A so-called aeration method has been developed. Originally, the ventilation method is a method for preventing dew condensation in the wall. Therefore, various draining materials have been devised in order to communicate the ventilation layer with the outside air. (For example, refer to Patent Documents 1 to 5).
