Description

  The present invention relates to a heat insulating material having high ventilation performance and capable of removing moisture such as moisture in an outer wall and an outer heat insulating ventilation method using the heat insulating material.

As for the conventional outer heat insulation method, a method in which the heat insulating material is closely adhered to the poured concrete by an adhesive is often used, and according to this method, the moisture of the concrete passes through the heat insulating material and the heat insulating material becomes in a highly wet state. There is a possibility that the performance of the heat insulating material is lowered and further the deterioration of the heat insulating material is caused.
In addition, when the outer wall is a sticking method such as siding, moisture can be removed by a wide variety of ventilation methods. However, in the case of a coating method such as a wet method, it is difficult to provide a ventilation method.

Patent Document 1 also describes a method for removing moisture in the outer heat insulating outer wall. In Patent Document 1, an air flow is positively generated in the ventilation layer in the outer heat insulating outer wall due to a wind pressure difference between the windward and leeward of the outer heat insulating outer wall, and moisture such as moisture in the outer wall is removed.
