効果が損われがちとなる。Such insulated walls are prone to the following problems during cold seasons. In other words, during the cold season, indoor humidity increases significantly due to heating, but this moisture enters the walls and condenses, which wets the insulation and wood, reducing the performance of the insulation and causing the wood to rot. cause To deal with this problem, a method of installing a moisture-proof layer on the interior side of the room, such as interposing a moisture-proof sheet such as a polyethylene sheet between the insulation material and the interior material, prevents indoor water vapor from moving inside the wall. However, in the current general Ni-level, it is difficult to make the moisture-proof layer completely moisture-proof, so it is impossible to prevent water vapor from entering the inside of the wall. As shown in the issue,
In order to prevent the water vapor that has entered the inside of the wall from condensing and accumulating, a construction method has been proposed in which a ventilation layer is provided between the insulation material and the exterior material to allow the water vapor that has entered the wall to flow outside. In the case of highly breathable heat insulating materials such as glass wool, the effectiveness as a heat insulating material tends to be impaired due to cold air passing through the breathable layer.

I [ff The present invention was made with the aim of solving the above problems, and by arranging a sheet with excellent moisture permeability and water repellency on the outside of the heat insulating material, it is possible to improve the wall thickness without reducing the heat insulating properties. This allows water vapor that has entered the body to quickly escape.

するか、内装材を上記合成樹脂で被覆するとよい。According to the heat insulating wall of the present invention, even if indoor water vapor enters the inside of the wall through the interior material due to the use of the moisture permeable water repellent sheet, it quickly flows out to the outside. However, it is desirable to minimize the amount of indoor water vapor that enters the interior of the wall.To do this, it is necessary to use polyolefins such as polyethylene, polypropylene, polyethylene terephthalate, polybutylene terephthalate, etc. between the insulation material and the interior material. It is preferable to provide a moisture-proof layer made of a moisture-proof sheet such as polyester, nylon 6, nylon 66, or other polyamide, or to construct the interior material itself from the above-mentioned synthetic resin, or to cover the interior material with the above-mentioned synthetic resin.

で蕗断され、断熱性の低下を少なくする。The i3 wet to water sheet according to the present invention is the i3! Although it may be laminated on an exterior material having water-based properties and 18 water-based properties, it is preferably placed on the outside of the insulation material in an insulating wall with a ventilation layer provided between the insulation material and the exterior material. As a result, the water vapor that has passed through the sheet is quickly discharged to the outside, and warm air is filtered through the sheet, reducing the reduction in insulation properties.

易に得ることができる。The nonwoven fabric constituting the moisture-permeable TA water sheet is made from fibers made of the synthetic resin mentioned above, and manufacturing methods include melt blowing, spunbonding, flash spinning, and fiber splitting. However, the melt-blowing method is preferable because the ultra-fine nonwoven fabric obtained by the melt-blowing method has excellent density, entanglement, self-fusion, and hydrophobicity, and is also economical. This method involves discharging the fibers from a number of spinnerets installed in a die and drawing them with high-speed airflow, and the average fiber diameter is 5 μm.
In the following, an entangled, self-fused nonwoven fabric with small openings can be easily obtained.

その間係はボアサイズの場合と逆となるため両者のバラ
ンスをとることが必要である。The average fiber diameter of the fibers of the nonwoven fabric needs to be in the range of 0.1 to 5 μm, preferably 0.5 to 5 μm. When the average w4 fiber diameter exceeds 5 μm, the opening becomes larger and I
a The aqueous property has decreased and the average fiber diameter has decreased to 0.1
When the thickness is less than μm, the moisture permeability decreases significantly. In order to satisfy water repellency, the maximum bore size of the nonwoven fabric must be 30μ.
The maximum bore size of the nonwoven fabric, which is preferably less than m, depends on the basis weight of the nonwoven fabric, the fiber diameter, the degree of compaction, its oil heat treatment manufacturing technology, processing technology, etc. On the other hand, the air permeability of the nonwoven fabric is preferably 20 cc/alI/sec or more, but the air permeability is also affected by the fiber diameter and compaction density.
The relationship between them is the opposite of that for bore size, so it is necessary to balance the two.
目付に関しては、５０ｇ／ｃｄ以下で、通気性とｔａ水
性のバランスを保つことが可能となる。Regarding the basis weight, it is possible to maintain a balance between air permeability and TA aqueous property by setting it to 50 g/cd or less.

樹脂のネットを積層するのがより望ましい。A nonwoven fabric as described above alone has satisfactory moisture permeability and water resistance, but is inferior in strength and abrasion resistance. Therefore, as reinforcement, it is desirable to laminate and integrate strong nonwoven fabrics, and it is more desirable to laminate a synthetic resin net on the nonwoven fabrics that have been integrated and laminated.
