Title:
GREEN ROOFS AND MODULES THEREFOR
Document Type and Number:
WIPO Patent Application WO/2011/095799
Kind Code:
A1
Abstract:
A roof tile (60) for a green roof (68) has a tray portion (20) for containing a vegetation growth medium (62) over a substantial expanse of the tile (60). Interlocking portions (24, 26) extend adjacent the side edges (16, 18) of the tile (60) and are configured so that one interlocking portion (24) of one tile (60) can be overlapped by the other interlocking portion (26) of another such tile (60) and guide rainwater which may fall between the tiles (60) to the lower edge (14) of the tiles. The tray portion (20) stops short of the upper edge (12) of the tile, and a support portion (22) extends between the tray portion (20) and the upper edge (12) so that the tray portion (20) of one tile (60) can overlap the support portion (22) of another such tile (60) so that the tray portions (20) of the tiles (60) are substantially contiguous. The growth medium (62) is in the form of beads (62), and the tile has a mesh (64) covering the growth medium (62) and attached to the upper edges (12) of the peripheral walls (32, 34) of the tray portion (20). The sizes of the mesh (64) and beads (62) are such that the majority of the beads (62) cannot pass through the mesh (64).
