CONSTRUCTION METHOD OF HEAT INSULATING LAYER
To provide a construction method suitable for constructing a heat insulating layer in winter or in cold regions.SOLUTION: A construction method of heat insulating layer in structure comprises at least steps of forming a first heat insulating layer on a surface of a building frame of the structure, and of forming, on the surface of the first heat insulating layer, a second heat insulating layer made of urethane foam having at least semi-noncombustibility in an exothermic test in accordance with ISO-5660. For the first heat insulating layer, urethane foam having a faster curing speed at low temperatures than the second heat insulating layer is used.SELECTED DRAWING: Figure 1
【課題】冬期や寒冷地での断熱層の構築に好適な施工法を提供する。【解決手段】構造物における断熱層の構築方法であって、構造物の躯体表面に対し、第１の断熱層を形成する工程と、前記第１の断熱層の表面に、ＩＳＯ－５６６０に準拠した発熱性試験において少なくとも準不燃性を有するウレタンフォームからなる第２の断熱層を形成する工程と、を少なくとも有し、前記第１の断熱層は、前記第２の断熱層よりも低温下での硬化速度が早いウレタンフォームを用いる。【選択図】図１
