FUNAKI MOTOKATSU / NISHIDA KAZUTOMO / KUWABARA TAKESHI

To provide a heat insulation material which does not necessarily need to continuously perform construction of laying of a heat insulation material and a lateral roofing exterior material, and can construct a lateral roofing exterior structure without hindrance even in rainfall during construction, and a lateral roofing exterior structure using the same.SOLUTION: A heat insulation material 2 which can form a heat insulation layer without a gap on a substrate surface and can arrange a lateral roofing exterior material 1 on the surface of the heat insulation layer includes an upper polymerization part having a projection part 22 with a surface layer portion extending to downstream side on the water lower end, and a lower polymerization part 23 having a flashing projection 231 continuous in a length direction to the water upper end. The surface is formed by two types of protruding regions 21A and 21B which are alternately arranged in the length direction and projections 213 for joint which are arranged between the regions 21A and 21B, and at least two or more intervals between the projections 213 and 213 for joint where a joint stay plate 9 is arranged are formed in the length direction.SELECTED DRAWING: Figure 1

【課題】横葺き外装構造の施工に際し、断熱材の敷設と横葺き外装材の敷設とを必ずしも連続的に施工する必要が無く、また施工の途中で降雨があっても支障なく横葺き外装構造を構築できる断熱材、及びそれを用いた横葺き外装構造を提供する。【解決手段】本発明は、下地表面に隙間ない断熱層を形成でき、該断熱層の表面には横葺き外装材１を配設することができる断熱材２であって、水下端に表層部分が水下側へ延出する突出部２２を備える上側重合部と、水上端に長さ方向に連続する水返し凸部２３１を備える下側重合部２３と、を備え、長さ方向に交互に配された二種の隆状領域２１Ａ，２１Ｂと、該領域２１Ａ，２１Ｂ間に配された継手用凸部２１３で表面が形成され、継手捨板９が配設される継手用凸部２１３，２１３間が、長さ方向に少なくとも二箇所以上形成されていることを特徴とする。【選択図】図１
