PROBLEM TO BE SOLVED: To provide an external heat insulation structure constructed in a building skeleton such as refrigerating/freezing storage warehouse which prevents interference between adjacent moisture-proof plates and can avoid deformation and peeling by the interference, even when the moisture-proof plate constituting a moisture-proof layer is thermally expanded while securing moisture-proof performance of the moisture-proof layer.SOLUTION: An external heat insulation structure includes a heat insulation layer A provided outside of a building skeleton and a moisture-proof layer B provided outside of the heat insulation layer A, where the moisture-proof layer B is constituted of a plurality of metallic moisture-proof plates 11 which are aligned by providing a gap 15 between the adjacent plates, and a gap moisture-proof portion 32 blocking the gap 15 following the change in the width of the gap 15.SELECTED DRAWING: Figure 5 【課題】冷蔵・冷凍倉庫等の建物躯体に対して構築される外断熱構造において、防湿層の防湿性能を確保しながら、防湿層を構成する防湿板が熱膨張した場合であっても、隣接する防湿板同士の干渉を防止して当該干渉による変形や剥離を回避することができる技術を提供する。【解決手段】建物躯体の外側に設けられた断熱層Ａと、当該断熱層Ａの外側に設けられた防湿層Ｂとを備えた外断熱構造であって、防湿層Ｂが、隣接間に隙間１５を設けて複数並設された金属製板状の防湿板１１と、隙間１５の幅の変化に追従して当該隙間１５を塞ぐ隙間防湿部３２とで構成されている。【選択図】図５
