の水分を通さないが、そのすきまから湿気は上部に逃す
もので、屋根裏に結露が発生しても、すぐに解消できる
ものである。(Prior Art) Conventionally, a base material for a roof has been devised so as to allow moisture to pass through but not moisture. In tiled reeds, a powder board (sawboard) is assembled and tiles are placed on top of it. Although the powdered plate reed does not allow moisture from above to pass through, moisture escapes from the gap to the upper part, and even if dew condensation occurs on the attic, it can be eliminated immediately.
近年、建築の技術の進歩により、家が気密となり湿気
がにげにくい構造になってきた。In recent years, with the progress of construction technology, houses have become airtight and have a structure that makes it difficult for moisture to escape.

る。（実開昭61−192021号公報）。In addition, with the progress of materials, a water-repellent and air-permeable porous sheet has been developed, and there is a proposal as a base material for a roof. (Japanese Utility Model Laid-Open No. 61-192021).
しかし多孔質シートは強度が弱いこと、およびシート
がすべりやすいので、シート上での作業は出来なかっ
た。However, work on the sheet was not possible because the strength of the porous sheet was low and the sheet was liable to slip.

フィンよりなる滑り止めを設けた不織シートである。(Means for Solving the Problems) That is, the present invention is a non-woven sheet provided with a non-slip material made of a moisture-permeable polyolefin and having a non-slip material coated on at least one surface in an area of 10 to 80%. .
本発明の不織シートの比表面積は1m2/g以上である。
本不織シートは比表面積が大きく、通常の不織シートと
あるいは、フィルムのような全体面均一のものとは表面
のミクロ構造が異なるものである。The specific surface area of the nonwoven sheet of the present invention is 1 m 2 / g or more.
The present nonwoven sheet has a large specific surface area, and is different from a normal nonwoven sheet or one having a uniform overall surface such as a film in the surface microstructure.
