摘要:
A flashing assembly for use where a sloping roof (22) extends away from a wall (10) is a strip (28) of flexible flashing material (e.g. lead) bearing a layer of air permeable material (30), preferably fibrous or reticulated foam material. This spaces the strip (28) from the roof (22) and provides a ventilation path, e.g. to a gap (26) adjacent the wall. The strip also rises up the wall (10) and may be embedded in it, e.g. beneath a cavity tray (18). The upper portion of the strip may not bear the permeable material (30).

A venting device (10) comprising an annular wall (11), an annular flange (14) connected to the annular wall (11) and extending away from the annular wall (11) in the radial direction, and a cup-shaped member (16) connected to the annular wall (11). The cup-shaped member (16) defines a cavity with a peripheral edge (19) facing away from the flange (14) in the axial direction. The cup-shaped member (16) having a venting hole (20) allowing air to pass through the venting hole (20). the cup-shaped member (16) is invertible so that when inverted the peripheral edge (19) faces towards the flange (14) and so that a sheet material (100) such as an underroof can be accommodated between the flange (14) and the peripheral edge (19) with the peripheral edge (19) in sealing contact with the sheet material (100).

Le profilé de support présente une section en forme générale d'U en auge. Au moins l'une des branches 2a, 2b du U présente à son extrémité un rebord 3 replié vers l'extérieur et, à proximité du fond 7 de l'auge, une série de fentes longitudinales alignées 8 de ventilation et des crochets 9 fixés à la branche du côté externe et dont la partie d'accrochage 11 s'étend en direction du bord replié 3. Application à des systèmes de fermeture ventilée de faîtage ou d'arêtier de toiture posés sur des éléments de support fixés sur la charpente de faîte de la toiture.

摘要:
A roof vent (10) comprising a one piece plastic body including a base wall (16) having transversely spaced rows (17, 18) of integral vanes extending from one surface thereof. Preferably, one (17) of each of the rows has the vanes extending at an acute angle to the axis (32) of the base wall (16) and the other row (18) has the vanes extending at an oppositely directed acute angle. Thus air is vented through sinous paths when the roof vent (10) is positioned with the vanes engaging the roof and the base wall spaced from the roof. Water and snow are prevented by the vanes from entry beneath the vent into the building.
