Description

本発明は、断熱改修壁と住宅に関するものである。   The present invention relates to a heat-insulated renovation wall and a house.

近年、地球温暖化抑制(地球環境保護)の観点より、家電製品や産業機器の省エネルギー化と並び住宅等の建物の省エネルギー化も取り組むべき重要な課題となっている。そのため、様々な断熱改修壁が提案されている(例えば、非特許文献1及び特許文献1参照)。   In recent years, from the viewpoint of suppressing global warming (protecting the global environment), energy savings for buildings such as houses as well as energy savings for home appliances and industrial equipment have become important issues. For this reason, various heat insulating renovation walls have been proposed (see, for example, Non-Patent Document 1 and Patent Document 1).

非特許文献1に示されているように、昭和55年省エネルギー基準レベルの在来木造住宅(築24年の木造在来軸組工法2階建て住宅)の2階天井及び1階床下の断熱改修を行った場合、天井では小屋裏の既存断熱を残し、その上に新規断熱材を吹き込み、また床では床下から根太間に断熱材を充填し根太下にも同様の断熱材の充填を行う。施工はそれぞれ作業員3名(約5時間)・監督1名、作業員5名(約10時間)・監督2名で行い、約16万円と約37万円の費用がかかっている。   As shown in Non-Patent Document 1, the insulation of the second-floor ceiling and the first-floor floor of a conventional wooden house with a level of energy conservation standards in 1980 (24-year-old wooden conventional frame construction method 2-story house) In the case of the above, the existing heat insulation of the hut is left on the ceiling, and a new heat insulating material is blown on the ceiling. On the floor, the heat insulating material is filled from under the floor to the joists, and the same heat insulating material is filled under the joists. Construction is done by 3 workers (about 5 hours) and 1 supervisor, 5 workers (about 10 hours) and 2 supervisors, respectively, and costs about 160,000 yen and 370,000 yen.

図4は、特許文献1により開示されている従来の断熱改修壁の概略断面図である。図4に示すように、特許文献1における従来の断熱改修壁は、躯体α上にボード102を形成した既存壁よりなる下地101上に略台形状の胴縁103を複数本固定し、胴縁103上に片面粘着テープを貼着し、壁下地全面に現場発泡型の合成樹脂発泡体104を吹き付けると共に胴縁103間に空間105ができるように形成し、次に、片面粘着テープを剥すことにより胴縁103の表面を露出させ、胴縁103上に乾式壁材107を施工している。   FIG. 4 is a schematic cross-sectional view of a conventional heat-insulated renovation wall disclosed in Patent Document 1. As shown in FIG. 4, the conventional heat insulation repair wall in Patent Document 1 fixes a plurality of substantially trapezoidal trunk edges 103 on a base 101 made of an existing wall in which a board 102 is formed on a housing α, A single-sided adhesive tape is affixed on 103, sprayed with an in-situ foam-type synthetic resin foam 104 over the entire wall base, and formed so that a space 105 is formed between the trunk edges 103, and then the single-sided adhesive tape is peeled off. Thus, the surface of the trunk edge 103 is exposed, and the dry wall material 107 is constructed on the trunk edge 103.

Costs about 370,000 yen for 5 workers (about 10 hours) and 2 supervisors.

また特許文献1による従来の断熱改修壁では、住宅駆体の断熱性能を向上させるため、下地101上に略台形状の胴縁103を複数本固定し、胴縁103上に片面粘着テープを貼着し、壁下地101全面に現場発泡型の合成樹脂発泡体104を吹き付けると共に胴縁103間に空間105ができるように形成する。次に、片面粘着テープを剥すことにより胴縁103の表面を露出させ、胴縁103の表面に貼付した粘着テープによって、胴縁103上に防水シート106と乾式壁材107を施工する。   Moreover, in the conventional heat insulation renovation wall by patent document 1, in order to improve the heat insulation performance of a housing drive body, multiple substantially trapezoidal trunk edges 103 are fixed on the base | substrate 101, and a single-sided adhesive tape is affixed on the trunk edge 103. FIG. In-situ foaming type synthetic resin foam 104 is sprayed on the entire surface of the wall base 101 and a space 105 is formed between the barrel edges 103. Next, the surface of the trunk edge 103 is exposed by peeling the single-sided adhesive tape, and the waterproof sheet 106 and the dry wall material 107 are applied on the trunk edge 103 with the adhesive tape attached to the surface of the trunk edge 103.

また、外被材15は、芯材14側より、ポリエチレン等による熱溶着層18、10μm以下のアルミ箔19、ナイロンまたはポエチレンテレフタレート等よりなる第2の保護層20、ナイロンまたはポエチレンテレフタレート等よりなる第1の保護層21より構成されている。   Further, the outer cover material 15 includes, from the core material 14 side, a heat-welded layer 18 made of polyethylene or the like, an aluminum foil 19 having a thickness of 10 μm or less, a second protective layer 20 made of nylon or polyethylene terephthalate, nylon or polyethylene terephthalate, etc. The first protective layer 21 is made of.

次に具体的に断熱改修方法について説明する。断熱改修を行う住宅の従来の既存壁11に真空断熱材10を複数枚利用し、既存壁11の全面を覆うように配置する。この時、前記部位に真空断熱材10が整数枚配置の場合に、既存壁11に余りが生じた場合には、真空断熱材10を芯材14のない部分で切断して、既存壁11に配置し、既存壁11の多くの部分を真空断熱材10で覆う。   Next, the heat insulation repair method is demonstrated concretely. A plurality of vacuum heat insulating materials 10 are used for the existing existing wall 11 of the house to be heat-insulated and repaired so as to cover the entire surface of the existing wall 11. At this time, in the case where an integer number of the vacuum heat insulating materials 10 are arranged in the portion, if there is a remainder in the existing wall 11, the vacuum heat insulating material 10 is cut at a portion without the core material 14 to form the existing wall 11. It is arranged and many parts of the existing wall 11 are covered with the vacuum heat insulating material 10.

この時、真空断熱材10の既存壁11側及び突き刺し防止板13側には平板板状の保護層12A,12Bが設けられている。また、突き刺し防止板13の室内側表面には真空断熱材10の芯材14の配置位置が記載されている。   At this time, on the existing wall 11 side and the stab prevention plate 13 side of the vacuum heat insulating material 10, flat plate-like protective layers 12A and 12B are provided. Moreover, the arrangement position of the core material 14 of the vacuum heat insulating material 10 is described on the indoor side surface of the stab prevention plate 13.

次に、板状の合板22を真空断熱材10の外周の芯材14を有しないヒレ部23の対向する外被材15同士が熱溶着されている部分に合わせて釘・ネジ等で固定する。次に、突き刺し防止板13を真空断熱材10の上に設置し、突き刺し防止板と合板22が合致する位置に釘・ネジ等で突き刺し防止板13を固定する。また、この既存壁11に窓、扉が存在したり、真空断熱材10の寸法が既存壁11に合わない場合は、以下の様に実施する。   Next, the plate-like plywood 22 is fixed with a nail, a screw, or the like in accordance with a portion where the facing covering materials 15 of the fin portion 23 not having the core material 14 on the outer periphery of the vacuum heat insulating material 10 are heat-welded. . Next, the stab prevention plate 13 is installed on the vacuum heat insulating material 10, and the stab prevention plate 13 is fixed to the position where the stab prevention plate and the plywood 22 coincide with each other with a nail, a screw or the like. Moreover, when a window and a door exist in this existing wall 11, or the dimension of the vacuum heat insulating material 10 does not match the existing wall 11, it implements as follows.

断熱改修を行う住宅の従来の既存壁11に真空断熱材10を複数枚利用し、既存壁11の窓・扉等の枠24及びその開口部は避けて全面を覆うように配置する。窓・扉等の枠24や既存壁11の端にかかる場合、真空断熱材10はできるだけ目地部25でカットし、既存壁11になるべく多くの真空断熱材10が配置できるように真空断熱材10を配置する。目地部25でカットしなかった場合は、真空断熱材10の芯材14が切断面よりこぼれるためテープ等により切断面の手当を行う。この時、真空断熱材10の既存壁11側及び突き刺し防止板13側には平板板状の保護層12A,12Bが設けられている。   A plurality of vacuum heat insulating materials 10 are used for the existing existing wall 11 of the house to be heat-insulated, and the existing wall 11 is arranged so as to cover the entire surface while avoiding the frame 24 such as windows and doors and the opening thereof. When it is applied to the frame 24 such as a window / door or the end of the existing wall 11, the vacuum heat insulating material 10 is cut at the joint portion 25 as much as possible, and the vacuum heat insulating material 10 is arranged so that as many vacuum heat insulating materials 10 as possible can be arranged on the existing wall 11. Place. When the joint portion 25 is not cut, the core 14 of the vacuum heat insulating material 10 spills from the cut surface, and the cut surface is treated with a tape or the like. At this time, on the existing wall 11 side and the stab prevention plate 13 side of the vacuum heat insulating material 10, flat plate-like protective layers 12A and 12B are provided.

次に、板状の合板22を既存壁11の外周部及び窓・扉等の枠24等の外周部に配置された真空断熱材10の外周の芯材14を有しないヒレ部23または目地部25に合わせて釘・ネジ等で固定する。この時に、芯材14部を釘等で打たないように注意する。   Next, the fin part 23 or joint part which does not have the core 14 of the outer periphery of the vacuum heat insulating material 10 arrange | positioned the plate-like plywood 22 in the outer peripheral part of the existing wall 11 and frame 24, such as a window and a door Fix to 25 with nails, screws, etc. At this time, care should be taken not to hit the core 14 with nails or the like.

次に、既存壁11及び窓・扉等の枠24等の形状に合わせてカットされたものを含む突き刺し防止板13を真空断熱材10の室内側に設置し、突き刺し防止板13と合板22が合致する位置に釘・ネジ等で突き刺し防止板13を固定する。   Next, the stab preventive plate 13 including the existing wall 11 and the frame 24 such as a window / door is cut to match the shape of the vacuum heat insulating material 10, and the stab preventive plate 13 and the plywood 22 are provided. The stab prevention plate 13 is fixed to the matching position with a nail, a screw or the like.

この時、真空断熱材10を設置する既存壁11の表面から突き刺し防止板13の室内側表面までの距離は、既存壁11の表面から断熱改修を行う既存壁11の表面と略平行の窓・扉等の枠24の表面までの距離より小さくなるようにする。または、突き刺し防止板13の室内側の面が枠24の室内側の面よりも室内側に突出しないようにする。   At this time, the distance from the surface of the existing wall 11 on which the vacuum heat insulating material 10 is installed to the indoor side surface of the stab prevention plate 13 is a window substantially parallel to the surface of the existing wall 11 to be insulated and repaired from the surface of the existing wall 11. The distance is made smaller than the distance to the surface of the frame 24 such as a door. Alternatively, the indoor side surface of the stab prevention plate 13 is prevented from projecting indoors more than the indoor side surface of the frame 24.

既存壁11の表面から断熱改修を行う既存壁11の表面と略平行の窓・扉等の枠24の表面までの距離(以下距離Lと称する)は、当社が調査を行ったところ約5〜20mmであり、これに対しては以下の例の様に構成する。下記(1)では、突き刺し防止板13の厚みが7mm未満となるため、画鋲(はり部の長さ7mm未満)を断熱改修後の壁に使用した場合、真空断熱材10に突き刺しによりピンホールが発生し断熱劣化が生じる。   The distance (hereinafter referred to as distance L) from the surface of the existing wall 11 to the surface of the frame 24 such as a window / door substantially parallel to the surface of the existing wall 11 to be insulated is about 5 to 5 For this, it is constructed as in the following example. In the following (1), since the thickness of the stab prevention plate 13 is less than 7 mm, when a thumbtack (the length of the beam portion is less than 7 mm) is used for the wall after the heat insulation modification, a pinhole is pierced by the puncture of the vacuum heat insulating material 10. Occurs and adiabatic deterioration occurs.

Existing wall / protection layer / wire seal multi-core vacuum insulation (3 mm or more) / protection layer / stab prevention plate (7 mm or more) / wallpaper After installation of the stab prevention plate 13, wallpaper 26 is installed on the indoor side of the stab prevention plate 13. By doing so, the thermal insulation repair is completed.

真空断熱材10の熱伝導率を0.0040W/m/K、厚みが3mmの場合その熱抵抗は0.75m2・K/Wとなり、これはグラスウール10Kの厚み約38mmに相当する。この値は、1980年から1991年の住宅の旧省エネ基準の断熱性能を1992年の新省エネ基準の断熱性能に引き上げるレベルである。   When the heat conductivity of the vacuum heat insulating material 10 is 0.0040 W / m / K and the thickness is 3 mm, the thermal resistance is 0.75 m 2 · K / W, which corresponds to the thickness of the glass wool 10K of about 38 mm. This value is a level which raises the heat insulation performance of the old energy saving standard of the house from 1980 to 1991 to the heat insulation performance of the new energy saving standard of 1992.

ちなみに、日本国内に上記旧省エネ基準の住宅は1500万戸、新省エネ基準の住宅は600万戸存在するが、上記旧省エネ基準よりも低い基準の住宅は3300万戸存在する。これより、真空断熱材10の厚みが3mmでも断熱性能の大きな改善を行うことができる。更に、真空断熱材10の厚み10mmのものを断熱改修に使用した場合には、その熱抵抗は2.48m2・K/Wとなり、上記1980年から1991年の住宅の旧省エネ基準の断熱性能を1998年の次世代省エネ基準の断熱性能に一気に引き上げるレベルとなる高断熱化が図れる。   By the way, there are 15 million houses in the old energy-saving standards and 6 million houses in the new energy-saving standards in Japan, but 33 million houses have standards lower than the old energy-saving standards. Thereby, even if the thickness of the vacuum heat insulating material 10 is 3 mm, the heat insulation performance can be greatly improved. Furthermore, when a vacuum insulation material having a thickness of 10 mm is used for heat insulation retrofit, the thermal resistance is 2.48 m 2 · K / W, and the heat insulation performance of the old energy saving standard of the house from 1980 to 1991 is achieved. It is possible to achieve high heat insulation, which is a level that can be raised to the heat insulation performance of the next generation energy saving standard of 1998.

以上より、複数の芯材14のそれぞれが独立した減圧空間内に位置するように、隣接する芯材14と芯材14との間と各芯材14の周囲に外被材15(熱溶着層18)同士を熱溶着した真空断熱材10を断熱改修壁に適用したことと、真空断熱材10の室内側に突き刺し防止板13を用いていることにより、本断熱改修においては真空断熱材10の断熱劣化を防止できることより真空断熱材10の高断熱性は保持され、従来の断熱改修の様に住宅の外壁を壊すことなく簡単に高性能な断熱改修が行うことができる効果が得られる。   As described above, the jacket material 15 (thermal welding layer) is formed between the adjacent core materials 14 and around each core material 14 so that each of the plurality of core materials 14 is located in an independent decompression space. 18) By applying the vacuum heat insulating material 10 thermally welded to each other to the heat insulating repair wall and using the stab prevention plate 13 on the indoor side of the vacuum heat insulating material 10, Since the heat insulation deterioration can be prevented, the high heat insulation property of the vacuum heat insulating material 10 is maintained, and an effect that a high-performance heat insulation renovation can be easily performed without breaking the outer wall of the house as in the conventional heat insulation renovation is obtained.

なお、本実施の形態では、真空断熱材10に線シール多芯真空断熱材を用いた場合を説明したが、線シール多芯真空断熱材の代わりに、線シール多芯真空断熱材の特徴に加えて、外被材15の間に芯材14がない部分の外被材15(熱溶着層18)同士を密着させて、密着した外被材15(熱溶着層18)同士を熱溶着してなり、外被材15(熱溶着層18)同士が密着する全ての部分の外被材15(熱溶着層18)同士が熱溶着されている特徴を有する面シール多芯真空断熱材を適用した場合には、上記特徴により断熱改修を行う既存壁11への面シール多芯真空断熱材の設置等において面シール多芯真空断熱材の芯材14近傍にピンホールが発生しても、この部分は線シール多芯真空断熱材では外被材15(熱溶着層18)同士が熱溶着層されていないが、面シール多芯真空断熱材はこのピンホール部分は熱溶着されているため、ピンホールによる断熱劣化を防止できる効果が得られる。   In the present embodiment, the case where a wire seal multi-core vacuum heat insulating material is used as the vacuum heat insulating material 10 has been described, but instead of the wire seal multi-core vacuum heat insulating material, the characteristics of the wire seal multi-core vacuum heat insulating material are used. In addition, the outer jacket material 15 (thermal welding layer 18) in a portion where the core material 14 does not exist between the outer jacket materials 15 is brought into close contact with each other, and the adhered outer jacket material 15 (thermal welding layer 18) is thermally welded. Applying a face seal multi-core vacuum heat insulating material having a feature that the outer cover material 15 (thermal welding layer 18) of all the portions where the outer jacket material 15 (thermal welding layer 18) is in close contact with each other is thermally welded In such a case, even if a pinhole occurs in the vicinity of the core 14 of the face seal multi-core vacuum heat insulating material in the installation of the face seal multi-core vacuum heat insulating material on the existing wall 11 that performs the heat insulation repair due to the above characteristics, The part is a wire seal multi-core vacuum heat insulating material, and the jacket material 15 (thermal welding layer 18) is thermally welded to each other. Although not, because face seal multi-core vacuum heat insulator is pinhole portion is heat-welded, the effect of preventing the insulation degradation due to pinholes is obtained.

また、真空断熱材10を設置する既存壁11の表面から突き刺し防止板13の室内側表面までの距離は、距離Lと同等かそれより小さくなっているため、断熱改修後には、突き刺し防止板13等よりなる壁の内側に窓・扉等の枠24等は埋まることがないため見た目が非常に良好なると共に非常な圧迫感を感じることがない効果が得られる。また、突き刺し防止板13等よりなる壁と窓・扉等の枠24等との厚みの差の部分も見えないこととなり、この部分の見栄えに関わる処理も行う必要がない効果も得られる。   In addition, since the distance from the surface of the existing wall 11 where the vacuum heat insulating material 10 is installed to the indoor side surface of the stab prevention plate 13 is equal to or smaller than the distance L, the stab prevention plate 13 after the heat insulation repair. Since the frame 24 such as the window / door is not buried inside the wall made of the like, the appearance is very good and the effect of not feeling a very tight feeling is obtained. Further, the difference in thickness between the wall made of the stab prevention plate 13 and the like and the frame 24 such as the window / door cannot be seen, and there is an effect that it is not necessary to perform processing related to the appearance of this part.

また、突き刺し防止板13の室内側には壁紙26が設けられているため、室内としての
見栄えを確保できると共に、壁紙26の追加により更に室内側からの衝撃等に対する真空断熱材10の断熱劣化を防止できる効果が得られる。また、突き刺し防止板13の固定においては、釘・ネジ等を使用するが、固定後のこれらの上に壁紙26を貼ることにより、これらの跡を隠すことができる効果も得られる。
Further, since the wallpaper 26 is provided on the indoor side of the stab prevention plate 13, the appearance of the room can be ensured, and the addition of the wallpaper 26 further reduces the heat insulation deterioration of the vacuum heat insulating material 10 against the impact from the indoor side. The effect which can be prevented is acquired. In addition, nails and screws are used to fix the stab prevention plate 13, but the effect of being able to hide these marks can be obtained by pasting the wallpaper 26 on these after fixing.

また、突き刺し防止板13の室内側の表面には芯材14位置が記載されているため、突き刺し防止板13の固定において、芯材14の場所を避けて釘・ネジ等により固定することができるため、突き刺し防止板13の固定における断熱劣化を防止することができる効果が得られる。   Further, since the position of the core member 14 is described on the indoor surface of the stab preventing plate 13, the stab preventing plate 13 can be fixed by a nail, a screw or the like while avoiding the location of the core member 14. For this reason, an effect of preventing heat insulation deterioration in fixing the stab prevention plate 13 is obtained.

また、突き刺し防止板13の材料として石膏ボードを適用した場合、石膏ボードは木材に比較し安価であり、湿度により変形が小さくまた難燃性を有しているため、断熱改修用として適している効果が得られる。   Moreover, when a gypsum board is applied as the material for the stab prevention plate 13, the gypsum board is less expensive than wood, and is less deformable due to humidity and has flame resistance, so it is suitable for heat insulation repair. An effect is obtained.

また、室内側からの突き刺しによる断熱劣化は、ポスター等を壁に貼るための画鋲がメインである。これに対し、距離L≧10mmの場合には真空断熱材17の厚みは3mm以上確保できるため、突き刺し防止板13の厚みは7mm以上とすることが可能となる。この場合、画鋲の針部の長さは7mmより若干短いため、突き刺し防止板13の厚みが7mm以上であれば画鋲が突き刺し防止板13を突き破り断熱劣化を防止できる効果が得られるため、断熱改修後に断熱劣化による断熱性能の劣化を避けることができる効果が得られる。   In addition, heat insulation deterioration due to piercing from the indoor side is mainly a thumbtack for attaching a poster or the like to a wall. On the other hand, when the distance L ≧ 10 mm, the thickness of the vacuum heat insulating material 17 can be secured to 3 mm or more, so that the thickness of the stab prevention plate 13 can be set to 7 mm or more. In this case, since the length of the needle portion of the thumbtack is slightly shorter than 7 mm, if the thickness of the stab preventing plate 13 is 7 mm or more, the thumbtack can penetrate the stab preventing plate 13 and prevent heat insulation deterioration. The effect which can avoid the deterioration of the heat insulation performance by heat insulation deterioration later is acquired.

また、真空断熱材10と既存壁11の間及び真空断熱材10と突き刺し防止板13の間の少なくとも一方に保護層12A,12Bが設けられているため、真空断熱材10設置時において、真空断熱材10と既存壁11または突き刺し防止板13との擦れ等による断熱劣化を防止する事ができる効果が得られる。   Further, since the protective layers 12A and 12B are provided between the vacuum heat insulating material 10 and the existing wall 11 and at least one between the vacuum heat insulating material 10 and the stab prevention plate 13, the vacuum heat insulating material 10 is installed when the vacuum heat insulating material 10 is installed. The effect which can prevent the heat insulation deterioration by the rubbing etc. with the material 10 and the existing wall 11 or the stab prevention board 13 is acquired.

また、保護層12A,12Bが断熱性を有している場合は、保護効果による断熱劣化防止に加え、真空断熱材10には目地部25が存在し、その部分は断熱ができていない状態にあるが、保護材12は断熱性を有しているため、断熱性のない目地部25の断熱を行えると共に、目地部25以外の部分の断熱性を強化できる効果が得られる。   Further, when the protective layers 12A and 12B have heat insulation properties, in addition to preventing heat insulation deterioration due to the protective effect, the vacuum heat insulating material 10 has joint portions 25, and the portions are not thermally insulated. However, since the protective material 12 has heat insulating properties, it is possible to insulate the joint portions 25 having no heat insulating properties and to enhance the heat insulating properties of portions other than the joint portions 25.

また、保護層12A,12Bが難燃性を有している場合は、保護効果による断熱劣化防止に加え、難燃性の効果により保護層12A,12Bに着火しても保護層12A,12Bの難燃性により燃焼を防止できる効果が得られる。   In addition, when the protective layers 12A and 12B have flame retardancy, in addition to preventing the heat insulation deterioration due to the protective effect, even if the protective layers 12A and 12B ignite due to the flame retardant effect, the protective layers 12A and 12B The effect which can prevent combustion by flame retardance is acquired.

また、保護層12A,12Bの既存壁11側の少なくとも一部に接着部27が設けられているため、真空断熱材10を既存の壁、床、天井に配置する場合、接着部27をこれらに接着することにより、真空断熱材10の設置位置に対する仮止め効果が得られ、真空断熱材10の固定に対する位置決めがキッチリ行えると共に、真空断熱材10固定時おける位置ずれを防止でき、断熱改修作業の効率化または作業人数の低減を図ることができる効果が得られる。   Moreover, since the adhesion part 27 is provided in at least one part by the side of the existing wall 11 of protective layer 12A, 12B, when arrange | positioning the vacuum heat insulating material 10 to an existing wall, a floor, and a ceiling, the adhesion part 27 is set to these By adhering, a temporary fixing effect for the installation position of the vacuum heat insulating material 10 can be obtained, positioning for the fixing of the vacuum heat insulating material 10 can be performed smoothly, and a position shift when the vacuum heat insulating material 10 is fixed can be prevented, and the heat insulation repair work can be performed. It is possible to obtain an effect of improving efficiency or reducing the number of workers.

また、断熱改修壁として、保護層12A,12Bは断熱改修に適用する真空断熱材10にあらかじめ貼ってあってもよいし、別途張り付けでもよいし、既存壁11に貼ってもよく、貼り付けの有無を規定するものではない。また、突き刺し防止板13への保護層12A,12Bの貼り付けに関しても同様である。   Further, as the heat insulation renovation walls, the protective layers 12A and 12B may be pasted on the vacuum heat insulating material 10 applied to the heat insulation refurbishment in advance, may be pasted separately, or may be pasted on the existing wall 11 or pasted. It does not prescribe the presence or absence. The same applies to the attachment of the protective layers 12A and 12B to the stab prevention plate 13.

本発明にかかる断熱改修壁は、突き刺し防止板による室内側からの突き刺し等による真
空断熱材の断熱劣化の防止効果により真空断熱材を保護し、また、真空断熱材はスチレンフォーム等の汎用の断熱材に比べて断熱性能が非常に優れているため、断熱材部分の厚みを薄くでき、問題なく適用可能な範囲が広く実用的で、従来の住宅の壁・床・天井等をそのまま利用することによる簡易的・高性能な断熱改修を行うことができる効果があるので、住宅用の建物や商業用の建物、その他、断熱が必要な建物に有用である。
