The present disclosure discloses an interlocking roof tile comprising two groove extending over length of the interlocking roof tile at both lateral ends that create side walls at the distalmost ends of the interlocking roof tile. The grooves are created on top surface of the interlocking roof tile using a press machine that uses pressure to mold the cement into the interlocking roof tiles. The interlocking roof tile's at bottom surface is flat. The interlocking roof tile further comprises at least one nail opening, provided spatially from each other to mount and secure the interlocking roof tile to the roof. In order to couple a plurality of interlocking roof tiles in series, a first interlocking roof tile is placed coupled to the second roof tile such that side wall of the first interlocking roof tile is engaged with the groove of the second interlocking roof tile.

Plaque (10) de support adaptée pour s'emboîter dans un panneau photovoltaïque et permettre la fixation et l'intégration de ce panneau sur une toiture de bâtiment, ladite plaque (10) comprenant des moyens de chevauchement (12) verticaux étanches, des moyens d'emboîtement (14) latéraux étanches adaptés pour coopérer avec une plaque voisine, des plots de positionnement (36) de la plaque (10) qui sont surélevés, caractérisé en ce que la plaque (10) comporte une portion centrale formant capot (62) qui est délimité par une face avant (64) conçue pour être agencée en regard du panneau photovoltaïque et une face arrière (66), ledit capot (62) comportant une bouche (78) adaptée pour permettre la récupération de l'air interposé entre le panneau photovoltaïque et la face avant (64) du capot (62).

A roof tile has a curved upper surface that extends between leading and trailing edges,the upper surface and the leading edge being visible when the tile is laid with a plurality of similar tiles to form a roof having a plane that extends from an eave of the roof to a ridge of the roof and meets the upper surface of each tile. A curvature of the upper surface of the tile is such that, when the tile is laid, a junction between the leading edge and the upper surface of the tile lies below the plane. Wind blows up the roof from the eaves towards the ridge in the plane that meets the upper surface of each tile. Because the junction between the leading edge and the upper surface of the tile lies below the plane, the wind does not hit the junction as it is driven up the roof but instead hits the upper surface of the tile, away from the leading edge. In this way, the driven wind substantially avoids the leading edge of the tile, which reduces turbulence in front of the leading edge thereby reducing the tendency for wind-driven rain to be driven between the tiles.

A kind of tile (100) is provided. The tile(100) comprises a mating surface(120) and a roofing surface(110),wherein the roofing surface is elevated above the mating surface and is shaped to guide or direct a liquid to flow from an upstream first end(112) to a downstream second end(114) under the influence of gravity when the mating surface rests on a leveled surface, and wherein the mating surface comprises a mating or coupling means(130) which is adapted to make complementary mating or coupling engagement with a support member(24) or a support surface having a complementary mating or coupling means. A roof comprising a plurality of tiles and a building structure comprising a roof constructed from a plurality of tiles are also provided.

A deck block adapted to be interconnected with other deck blocks to form an insulating deck for casting concrete. The deck block comprising a foam panel at least one hole extending into the panel from the one end toward an opposing end such that the hole has an open end and a closed end. At least one protrusion extends from the panel and the protrusion is matingly receivable in at least a portion of a hole of a like panel to interconnect the panels in an end-to-end relationship. The panel has a vertical groove extending from a bottom surface and intersecting the opening of the panel to provide a fluid flow channel from the opening to the bottom surface of the panel when the like panels are interconnected. The protrusion has a horizontal groove extending along a lower end thereof from a distal end of the protrusion to a proximal end thereof so as to intersect the vertical groove.
