2. Description of the Related Art Conventionally, various types of buildings have been used to block the heat of the outside air in summer and to keep the inside warm in winter. Insulation is put. Examples of the heat insulating material include a plate-shaped heat insulating plate made of a high-expanded polyethylene-based material or expanded polystyrene, and a fiber-based material such as glass wool or rock wool. These heat insulating plates are fitted between the vertical frames of the building, between the rafters, between the floor joists, and the like, and fixed to the vertical frames and the rafters. In particular, since the foamed resin-based heat insulating plate has an appropriate elasticity, it can be applied to a vertical frame, a rafter, etc. without gaps, efficiently shutting off the transmission of heat inside and outside the room, and keeping the room at a comfortable temperature. Can be kept.

[0003]

In the case of the above prior art, these heat insulating materials can prevent the heat generated by the heating of the room from escaping to the outside during the winter period. Since the temperature of the surface is low, dew condensation occurs on the indoor surface of the heat insulating material. When the water droplets due to the generated dew increase, the water droplets fall along the surface of the heat insulating material, and the water droplets fall on wood or the like which is a component of the building. Moldy or rotten parts of the wet parts of the timber have impaired the durability of the building. Further, there is also a problem that the wood, which is a structural material, becomes susceptible to termite damage due to moisture. In addition, since the indoor wall surface is lower in temperature than the room temperature in winter, there is also a problem that dew condensation occurs on the indoor wall surface.

[0004] The present invention has been made in view of the above-mentioned problems of the prior art, and reliably shuts off heat between the outside air and the inside air, and absorbs water vapor on the surface of the heat insulating material to prevent dew condensation. An object of the present invention is to provide a heat insulating material and a building humidity control sheet that enhance the durability of a building.
