<P>PROBLEM TO BE SOLVED: To provide an external heat-insulation greening member capable of considerably reducing maintenance cost in the case of covering a roof of a building with a creeping plant. <P>SOLUTION: The external heat-insulation greening member is a closed cell expansion molded article which has an expansion ratio of 10-90 and is provided with root region securing parts and creeping stem developing parts on the upper face of the greening member. Adjacent root region securing parts are connected together through a root region securing part connecting groove, and vegetation base materials are filled in the root region securing parts, the root region securing part connecting grooves and the creeping stem developing parts. The depth of the root region securing part is 30-200 mm, the depth of the vegetation base material of the creeping stem developing part is 0-40 mm, and an S<SB POS="POST">op</SB>/S<SB POS="POST">b</SB>ratio is 0.5-40, wherein S<SB POS="POST">b</SB>is the area of total root region securing parts consisting of the root region securing part and the root region securing part connecting groove and S<SB POS="POST">op</SB>is the area of total creeping stem developing parts consisting of the creeping stem developing part, vegetation base guide protrusions and peripheral parts 10. The creeping plant is grown on the upper face of the external heat-insulation greening member filled with the vegetation base material. <P>COPYRIGHT: (C)2012,JPO&INPIT |
