Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating material used for a partition such as a wall, a floor or a ceiling of a building such as a wooden house.

[0002]

Conventionally, as this kind, a heat insulating material made of urethane foam, polystyrene foam, polyethylene foam, etc., and a heat insulating material such as glass wool packed in a bag are disclosed in JP-A-56-154048. Wood is known.

[0003] However, in the heat insulating materials made of urethane foam, polystyrene foam, polyethylene foam, glass wool, etc., a molded product is used as a material.
Since glass wool and the like are used to form glass fibers, there is a problem that the production cost is high. In addition, even if these insulation materials become waste materials, they are different from those that corrode,
The process takes time.

Accordingly, an object of the present invention is to provide a heat insulating material which can be manufactured at low cost by using waste materials.

[0005]

According to a first aspect of the present invention, in a heat insulating material provided in a partition of a building, sawdust is dried, and the dried sawdust is provided in the partition. The sawdust can provide a heat insulating effect. Further, it is possible to effectively use the sawdust that has been conventionally discarded.

The filling portion is filled with dried sawdust, and the container main body is covered with a moisture-proof sheet having air permeability in one direction of the thickness of the container main body. As a result, the sawdust is not biased and can be used for building walls and the like. Also, if provided inside a partition such as a wall,
Sawdust absorbs moisture inside the building, and the moisture can be released to the outside. In addition, moisture intrusion from the outside is prevented by the moisture-proof sheet.

According to a third aspect of the present invention, in a heat insulating material provided at a partition of a building, a moisture-proof sheet having air permeability in one direction is overlapped on the front and back, and a plurality of bulging portions are formed on at least one of the front and back sheets. At the same time, the plurality of bulging portions are arranged vertically and horizontally, and a filling space is formed in the convex portion and between the other sheets by the sealing portion provided between these bulging portions, and the filling space is filled with dried sawdust. Heat insulation is obtained by the sawdust filled in the filling space, and by cutting along the seal part,
The heat insulating material can be formed in a size corresponding to the mounting location. Furthermore, since the heat insulating material can be rolled up, transportation and the like are easy.
