ROOF PANEL, ROOF AND BUILDING HAVING EXCELLENT THERMAL INSULATION PROPERTY
PROBLEM TO BE SOLVED: To provide a roof panel capable of efficiently cooling inside a building with chilled water supplied to the roof.SOLUTION: A roof panel of excellent thermal insulation property of the present invention includes a metallic plate 1 having a recess, a plating layer A formed at least on a surface with the recess of the metallic plate 1, and a covered layer B on a front layer side of the plated layer, and is characterized by: a plating composition of the plating layer A being Zn-Al-Mg-based; the covered layer B being an organic covered layer containing a heat-reflecting inorganic filler; a recess C formed on the covered layer B in a same form with the recess on the metallic plate having a depth from a reference surface of five times a plate thickness T of the metallic plate or greater and an opening with a shorter diameter between 5 to 20 times the plate thickness T; a nearest distance between edges of the adjacent recesses C being 2 to 5 times the shorter diameter of the opening of the recess C; a total area of the opening of the recess C on a surface of the covered layer B per 1 mof panel surface area being 0.048 to 0.157 m; and a calculated water retention amount held in the recess C when the panel is tilted 5 degrees from a horizontal surface being 50 cmor more per 1 m.SELECTED DRAWING: Figure 1
【課題】屋根に供給した冷却水による建造物内の効率的冷却を可能にする屋根パネルを提供すること。【解決手段】本発明の遮熱性に優れた屋根パネルは、凹部を有する金属板１と、該金属板１の少なくとも該凹部を有する面に設けためっき層Ａ及びその表層側の被覆層Ｂとを有する屋根パネルであり、めっき層Ａのめっき組成がＺｎ−Ａｌ−Ｍｇ系であること、被覆層Ｂが熱反射性無機系フィラーを含有する有機被覆層であること、金属板の該凹部の形状にならって被覆層Ｂに形成された凹部Ｃが、基準面に対して該金属板の板厚Ｔの５倍以上の深さと、板厚Ｔの５〜２０倍の開口短半径を有し、隣り合った凹部Ｃのエッジ間の最近接距離が凹部Ｃの開口短半径の２〜５倍で、パネル表面積１ｍ2あたりの被覆層Ｂ表面における凹部Ｃの合計の開口面積が０．０４８〜０．１５７ｍ2であり、なおかつ、パネルが水平面から５度傾斜した時に凹部Ｃに保持可能な計算保水量が１ｍ2あたり５０ｃｍ3以上であることを特徴とする。【選択図】図１
