る。On the other hand, in recent years, wooden houses are provided with a heat insulating material and a device for improving airtightness in order to improve habitability in winter and save heating energy. Also,
Even in temperate regions, it is recommended to use heat insulating materials to improve habitability in summer and save cooling energy.
【0004】従来、木造家屋の断熱構造は、外壁の断熱
工法によって大別すると、充填工法によるものと、外張
工法によるものに分けられる。Conventionally, the heat insulation structure of a wooden house is roughly classified into a heat insulation method for the outer wall and a heat insulation method for the outer wall.
【0005】充填工法は、主としてグラスウールやロッ

る工法である。The filling method is a method of inserting a fibrous heat insulating material of inorganic fiber such as glass wool or rock wool mainly between the outer wall frame members, and is the most widely used method in Japan at present.

ず、その点で建物の耐久性が優れているとされている。The external tension method is a method in which a plate-like heat insulating material mainly made of foamed plastic is stretched on the outdoor side of the outer wall shaft assembly, and an external finishing material is further provided on the outdoor side thereof. It is said that the durability of the building is excellent in that respect as it does not cause condensation on the outer wall.

うな問題がある。However, the heat insulating structure formed by the above-mentioned filling method has the following problems: breathability, heat insulation, airtightness,
There are the following problems in terms of workability, economy, and habitability. In addition, since the heat insulating structure by the outer-lining method can uniformly stretch the plate-shaped heat insulating material over the entire surface, it is superior to the filling method in terms of heat insulation, but there are still the following problems in other points. .

せる原因となる。(1) Filling method Breathability Normally, the outer wall portion formed by the filling method has a structure in which a fibrous heat insulating material is filled between outer wall shaft assembly members and sandwiched between an inner finishing material and an outer finishing material. No breathability of Therefore, warm indoor air with a large amount of water vapor enters and stays in the outer wall, which cools in the outer wall and causes dew condensation, which deteriorates the performance of the fibrous heat insulating material and accelerates corrosion of the outer wall frame. Becomes

しかし、外壁軸組及び繊維状断熱材充填部分は防風シー

になりがちである。Therefore, a windproof sheet for preventing the deterioration of the heat insulating property due to ventilation is provided on the outdoor side of the fibrous heat insulating material inserted between the outer wall shaft assembly members, and the fibrous heat insulating material and the outside It is partly performed to ventilate the inside of the outer wall by using a space communicating with the finishing material as a ventilation layer.
However, since the outer wall frame and the fibrous heat insulating material-filled portion are blocked by the windbreak sheet and do not come into direct contact with the outside air, the ventilation tends to be insufficient.

下の原因となる。また、繊維状断熱材は自立性がないの
で、外壁内でずり下がり、断熱性を低下させる原因とな
る。Since the fibrous heat insulating material in the filling method is inserted between the outer wall shaft assembly members, it is divided by the outer wall shaft assembly member, and a gap is apt to be generated between the fibrous heat insulating material and the outer wall shaft assembly member. It causes a decrease in heat insulation. In addition, since the fibrous heat insulating material does not have self-supporting property, the fibrous heat insulating material slides down inside the outer wall, which causes a decrease in heat insulating property.

ている。Airtightness It has been practiced to provide a moistureproof sheet such as a polyethylene sheet on the inside (outside of the room) of the interior finishing material to provide airtightness. I can't hope. For this reason, as described in the section of "Breathability", even if a measure for improving the breathability by the breathable layer is taken, a harmful effect due to infiltration of moisture from the indoor side is likely to occur.

が、繊維状断熱材に比して外壁軸組材間への挿入は施工
性が著しく悪いので優れた通気性と断熱性は得にくい。Workability In order to improve the airtightness even a little, it is necessary to install a moisture-proof sheet, and in order to provide a ventilation layer for reducing the adverse effect due to the airtightness which tends to be insufficient even with this moisture-proof sheet, windproof sheets are required. The construction of the sheet is indispensable, and it takes time and cost for these constructions. It is also possible to use a foamed plastic plate-shaped heat insulating material instead of the fibrous heat insulating material, but compared to the fibrous heat insulating material, the insertion between the outer wall shaft assembly materials is extremely poor in workability, so it has excellent air permeability. It is difficult to obtain heat insulation.
【0013】経済性 断熱材が外壁部内の中間部に位置しているので、室内の
冷暖房に際しては、外壁軸組の一部も同時に冷やしたり
暖めることになり、冷暖房エネルギーの無駄を生じる。Since the heat insulating material is located in the middle portion of the outer wall portion, when the room is heated or cooled, a part of the outer wall frame is also cooled or warmed at the same time, resulting in waste of cooling and heating energy.

ずる温度(体感温度)といわれている。Comfortability As described above, when the room is heated or cooled, part of the outer wall framework is also cooled or warmed at the same time. Therefore, not only the rising and cooling of the air conditioner is slow but also the comfort that people feel is that of the surrounding walls and ceiling. Since it is greatly affected by the surface temperature, it takes time to obtain a comfortable space. By the way, it is said that the temperature perceived by humans (sensible temperature) is obtained by adding room temperature and the surface temperature of surrounding walls and ceiling and dividing by two.

湿気が外壁軸組材に吸湿された場合には乾燥されにくい
状態となる。(2) External Covering Method The breathable outer wall frame is sandwiched between the plate-like heat insulating material on the outdoor side and the internal finishing material and is not exposed to the outside air. Therefore, when dried indoors or indoor moisture from a water heater or a humidifier is absorbed by the outer wall shaft assembly, it becomes difficult to dry.

設けることが推奨されている。Airtightness Since the plate-shaped heat insulating material made of foamed plastic generally has high moisture resistance and low hygroscopicity, it is considered that a moisture-proof sheet may not be provided. However, since it is feared that moisture in the room may leak from the joint between the plate-shaped heat insulating materials and reach the outside of the plate-shaped heat insulating material, it is recommended to provide the moisture-proof sheet on the indoor side of the plate-shaped heat insulating material.

工性を悪化させる原因となっている。By the way, in order to obtain airtightness, it is the simplest to attach the moisture-proof tape from the indoor side only to the joint portion between the plate-shaped heat insulating materials. However, since there is an outer wall skeleton on the indoor side of the plate-shaped heat insulating material and the joint cannot be completely covered with the moisture proof tape, it is recommended to provide a moisture proof sheet on the entire outer surface of the skeleton. As described above, it is a cause of deterioration in workability.

ると共に資材も余分に必要となる。Workability When the above-mentioned moisture-proof sheet is provided, the moisture-proof sheet is first constructed in a framed state where no wall is formed, that is, in the state where there is no stable base, and then the plate-like heat insulating material and the external finishing material are attached from above. In order. Construction of a moisture-proof sheet in an unstable state itself has poor workability, and particularly in construction on a windy day, since the moisture-proof sheet is covered, the workability becomes significantly poor. In order to prevent this, it is conceivable that the moisture-proof sheet is applied after the base plate is stretched, but the number of steps is increased by one and an extra material is required.
【0019】経済性 板状断熱材が外壁部の外面側に位置しているので、室内

暖めることになり、冷暖房エネルギーの無駄が大きい。Economical Since the plate-shaped heat insulating material is located on the outer surface side of the outer wall portion, when the room is heated or cooled, the entire outer wall framework is cooled or warmed at the same time, which results in a large waste of cooling and heating energy.
