Description

本発明は、既存の窓に取り付けて用いる断熱材に関し、さらに詳しくは、既存の様々なタイプの窓に簡単に着脱が可能で、気密性及び断熱効果が高く、製造時の組立ても容易な断熱材に関するものである。   The present invention relates to a heat insulating material used by being attached to an existing window. More specifically, the heat insulating material can be easily attached to and detached from various types of existing windows, has high airtightness and heat insulating effect, and is easy to assemble during manufacture. It relates to materials.

住宅に用いられる窓は、日常生活に必要な出入りや換気などの目的を達成するため、開閉機能を有する。
しかし、窓は住宅の気密性の観点から見ると、開閉機能を実現する構造を有するがゆえに、住宅の中で最も気密性が損なわれている部分であり、住宅の冷暖房効率の低下の大きな原因になっている。
近年、様々な省エネのための手法が提案されているが、住宅の冷暖房効率の上げることで省エネを達成するための手法が種々提案されている。
例えば、特許文献１では、断熱性を向上させるためサッシを２重にするタイプのものが提案されている。
しかしながら、サッシを２重にするタイプのものは、既存の家屋においては窓枠交換の工事が必要になりコストが高いなどの問題がある。
そのような理由から、既存の窓に装着することができる比較的低コストで導入可能なタイプのものなども提案されている。たとえば特許文献２には、窓ガラスの屋内側に隙間を隔てて固定的に採光断熱材が配置されており、採光断熱材が間に空気層を隔てて対向されている複数の合成樹脂フィルムと、複数の合成樹脂フィルム間に配置されたスペーサとを有し、採光断熱材の外周と窓ガラスとの間の隙間を封止するようにコーキング材が設けられている断熱構造が提案されている。また、特許文献３には、合成樹脂製の被覆体と、該被覆体とガラス面を固定する枠体とからなり、前記枠体は、多数の微細気孔を有する発泡体構造であると共に凹凸ガラス面の凹凸を吸収できる厚さを有し、一方の面にガラス面を固定するガラス面固定基材が設けられ、他方の面に該被覆体を固定する被覆体固定基材が設けられた断熱構造が提案されている。 A window used in a house has an opening / closing function in order to achieve purposes such as going in and out and ventilation necessary for daily life.
However, from the viewpoint of the airtightness of the house, the window has the structure that realizes the opening and closing function, so it is the part where the airtightness is most impaired in the house, which is a major cause of the decline in the cooling and heating efficiency of the house It has become.
In recent years, various methods for energy saving have been proposed, and various methods for achieving energy saving by increasing the cooling and heating efficiency of houses have been proposed.
For example, Patent Document 1 proposes a type in which sashes are doubled in order to improve heat insulation.
However, the double sash type has problems such as high cost because it requires a window frame replacement work in an existing house.
For this reason, a type that can be installed on an existing window and can be introduced at a relatively low cost has been proposed. For example, Patent Document 2 includes a plurality of synthetic resin films in which a daylighting heat insulating material is fixedly disposed on the indoor side of the window glass with a gap therebetween, and the daylighting heat insulating materials are opposed to each other with an air layer therebetween. And a heat insulating structure having a spacer disposed between a plurality of synthetic resin films and provided with a caulking material so as to seal a gap between the outer periphery of the daylighting heat insulating material and the window glass. . Patent Document 3 includes a cover made of a synthetic resin and a frame that fixes the cover and the glass surface. The frame has a foam structure having a large number of fine pores and an uneven glass. Insulation having a thickness capable of absorbing surface irregularities, provided with a glass surface fixing base material for fixing the glass surface on one side, and provided with a covering body fixing base material for fixing the covering on the other side A structure has been proposed.

しかしながら、特許文献２で提案されている断熱構造では、断熱材がコーキング剤による封止で窓に固定されるため、一度設置した後の取り外しが困難であるという問題があり、特許文献３で提案されている断熱構造では、断熱材の装着及び脱着は極めて容易に行うことができるが、窓を完全に密閉していないため、住宅の気密性が保たれず断熱効果が低いなどの問題があった。
このため、既存の様々なタイプの窓に簡単に設置することができ、取り外しが可能で、気密性及び断熱効果が高く、導入コストが安い断熱材の開発が要望されているのが現状である。 However, in the heat insulation structure proposed in Patent Document 2, since the heat insulating material is fixed to the window by sealing with a caulking agent, there is a problem that it is difficult to remove it once installed. In the heat insulation structure that is used, it is very easy to attach and detach the heat insulating material. However, since the window is not completely sealed, there is a problem that the airtightness of the house is not maintained and the heat insulating effect is low. It was.
For this reason, there is a demand for the development of a heat insulating material that can be easily installed on various types of existing windows, can be removed, has high airtightness and high heat insulating effect, and has low introduction cost. .

したがって、本発明の目的は、既存の様々なタイプの窓に簡単に設置することができ、取り外しが可能で、気密性及び断熱効果が高く、導入コストが安い断熱材を提供することにある。   Accordingly, an object of the present invention is to provide a heat insulating material that can be easily installed on various types of existing windows, can be removed, has high airtightness and heat insulation effect, and is low in the introduction cost.
