Definitions

  • This invention relates to an inorganic fiber thermal insulator to be used in walls, under floors, on ceilings and under roofs of wood and skeleton construction houses for the purpose of thermal insulation and sound absorption, and also to a thermal insulation structure using such a thermal insulator.
  • Inorganic fiber mats used for thermal insulation and sound absorption of houses are typically produced by applying thermosetting resin such as phenol resin to inorganic fiber such as glass wool or rock wool, subsequently building-up such inorganic fibers, heating them to form a built-up article, and cutting the built-up articles into a plate-shaped mat.
  • thermosetting resin such as phenol resin
  • inorganic fiber such as glass wool or rock wool
  • thermal insulators are arranged between pillars of houses for the purpose of thermal insulation and sound absorption.
  • Inorganic fiber mats of the type under consideration are used for wooden framework constructions, wooden panel constructions, prefabricated wall constructions, iron framework constructions, skeleton panel constructions and so on.
  • inorganic fiber mats are used in walls, they are arranged between pillars.
  • sleepers and floor joists When they are used on floors, they are arranged between sleepers and floor joists.
  • beams When they are used on ceilings, they are arranged between beams.
  • roofs they are arranged between rafters.
  • the selvages of mats running along the lateral edges thereof are rigidly anchored to the corresponding pillars by means of tacks or some other fasteners to hold them in place. Then, the mats also operate to dampproof the house.
  • Japanese Patent Publication No. Hei 7-116670 “Inorganic Fiber Mat” Japanese Patent Publication No. Hei 7-116670 “Inorganic Fiber Mat” (Japanese Patent No. 2130081) discloses “an inorganic fiber mat formed to show a plate-shaped profile and having built-up inorganic fiber arranged along the surfaces thereof, characterized in that longitudinal slits are formed perpendicular to the surfaces and alternately from the opposite surfaces at regular intervals with a small margin, and that the mat can be bent by 180 degrees along a slit to expose the inside”.
  • the inorganic fiber mat is provided with slits in a direction of a thickness of the mat in order to make it easily adaptable to different distances of two structures.
  • the mat is flexible, because it can be easily folded when it is placed in position.
  • the mat according to this patent document can be compressed only to reduce the thickness, and packaged. The patent document does not consider anything about transversal compression.
  • Such inorganic fiber mats are packaged for the purpose of raising the efficiency of storage and transportation. More specifically, the package of inorganic fiber mats is prepared by building-up a number of mat-shaped thermal insulators, compressing them in a thickness direction thereof, and putting the compressed mats into a bag. If the thermal insulators are short (e.g., 1,370 mm long), they are not bent when packaged. If the thermal insulators are long (e.g., 2,740 mm long), they may be bent longitudinally at the middle when packaged.
  • Japanese Utility Model Registration No. 3038186 discloses “a package of a group of inorganic fiber mats”.
  • debris of cut inorganic fiber mats have to be disposed as industrial wastes.
  • fasteners when used to anchor mats, they have to be removed when the building containing such mats is dismantled. The structures cannot be recycled unless the fasteners are removed.
  • a multilayered article of inorganic fibers is formed with longitudinal slits perpendicular to the top and bottom surfaces and alternately from the opposite surfaces. Said slit does not extend entirely in the thickness direction. Then, the article is compressed to reduce the thickness, and is packaged. The packaged mat is then unpacked on site, and folded by bending it along the slits by 180 degrees, so that the inorganic fibers are built-up longitudinally.
  • the slits need to be provided with margins so that the mat may not be cut apart. If the slits are shallow, the operation of folding the article is obstructed to make it difficult to produce a mat.
  • the slits are too deep, the articles can be cut apart. Additionally, since the slits are formed with margins, the top and bottom surfaces of the mat produce steps or undulations, which by turn produce gaps that are poorly thermally insulating when the mat is placed in position. Since the surfaces that are brought into contact with the corresponding structures are not bonded, the mat can hardly maintain its intended profile without some holding means. In other words, the mat is dimensionally unstable.
  • the compressed and packaged article is unpacked on site, made to restore its thickness, and then folded by 180 degrees to produce a mat.
  • the produced mat can show a short width if the thickness of the article is not restored sufficiently.
  • the produced mat can show a too large width due to the restoration too much. In this case, it is necessary to compress the mat in the width direction.
  • the mat may be forced out from the wall where it is arranged after being placed in position.
  • Packages of known mat-shaped insulators are also accompanied problems as pointed out below.
  • Inorganic fiber are built-up in parallel with the top and bottom surfaces (and in the transversal direction) of known mat-shaped insulators. Therefore, packages of known insulators can be compressed in a direction of a thickness. However, when the insulator is compressed transversally, the fibers can be destroyed. Thus, when the package is unpacked on site to release the insulator from the compressed state, the width of the insulator may not be restored.
  • No prior art discloses a packages prepared by transversally compressing insulators. Hence, there is a demand for packages of insulators capable of being compressed transversally, in view of the efficiency of transportation.
  • the lateral surfaces of the insulator are inclined.
  • longitudinal cuts are formed on the lateral surfaces of the insulator so as to make the insulator partially compressible.
  • At least one of the surfaces of the insulator may be coated by a facing material.
  • said insulator and the facing material are bonded to each other by means of an adhesive agent.
  • the adhesive agent may be partially applied to the insulator and/or the facing material, and may be entirely applied to surfaces of the insulator and/or the facing material.
