Description

ROOF VENTILATION TILE This invention relates to a roof ventilation tile.
It is common in roof structures of buildings for high levels of insulation to be used in order to reduce heat losses from the building. However, this increases the necessity to provide good ventilation to the interior of the roof structure in order to prevent condensation of moisture.
One solution to this problem is described in our U.K. Patent No. 2,089,968 in which a ventilator can be disposed between the insulation and the roof structure in the region of the eaves. Another solution is described in U.K. Patent No. 2,027,469 in which a roof ventilation tile is provided in the roof structure.
It is an object of the present invention to provide an improved roof ventilation tile.
According to the present invention there is provided a roof ventilation tile comprising a tile member adapted to be arranged between roof covering elements in a row of roof covering elements in a roof structure, said tile member preferably having an external surface adapted to be disposed substantially in the plane of said row of roof tiles, and preferably said tile member being provided with at least one first aperture for providing an air flow therethrough, the or each aperture being disposed in the external surface.
Advantageously, the roof ventilation tile further includes a ventilation chamber defined beneath the external surface.
Preferably the or each first aperture is adapted to provide a ventilation path between an external environment and the ventilation chamber for desirably at least one second aperture is provided in the tile member, which provides a ventilation path between the ventilation chamber and an interior of the roof structure.
A flyscreen or mesh may be disposed on the first and or second apertures.
It is preferred that the tile member comprises an upper tile member and a lower tile member. The or each aperture may be disposed in the upper tile member, whilst the or each second aperture may be disposed in the lower tile member.
Advantageously the roof tile ventilator includes baffle means disposed in the air flow path between the first and second apertures. Preferably the baffle means comprises at least one baffle provided on the upper and or lower tile members.
The baffle means is desirably arranged in the air flow path between the first and second apertures, such that there is no straight line air flow path between the first and second apertures.
The lower tile member may include a lower surface which is adapted to collect moisture, and which is adapted to direct the collected moisture downwardly towards the moisture outlet. The moisture outlet may be defined by air between the upper and lowe tile members.
The baffle means may be provided with at least one lip which enables moisture to flow over the baffle means to the moisture outlet.
Preferably the tile member is adapted to be disposed in two adjacent rows of roof covering elements, between roof covering elements of each row.
According to the present invention there is provided a roof ventilation tile comprising a tile member. adapted to be arranged between roof covering elements in a row of roof covering elements in a roof structure, said tile member having an external surface adapted to be disposed substantially in the plane of said row of roof tiles, and said tile member being provided with at least one first aperture for providing a air flow therethrough, the or each first aperture being disposed in the external surface.
The roof covering elements may be, for example,.
tiles, slates or shingles.
With roof structures formed by curved tiles (which comprises a plurality of juxtaposed ridges and troughs) the plane of the row of roof covering elements is defined as the plane which passes through the ridges of the tiles.
The baffle means may be disposed in the plane of the row of roof covering elements. However, it is preferred that the baffle means is disposed below the plane of the row of roof covering elements.
The ventilation tile can be adapted to look like the roof covering elements in the rest of the roof structure and can be provided with similar colouring.
The ventilation member can be shaped to ccrrespond to either plain tiles or curved tiles.
The ventilation tile may be made of a plastics material and may be formed by injection moulding.
The ventilation tile according to the invention provides a free flow of air to the interior of the roof structure, whilst restricting the flow of moisture thereof.
The tile does not protrude above the plane of the row of the roof covering elements by virtue of the provision of the external surface of the ventilation tile in or below the plane of the row of the row covering elements. This reduces the tendency of moisture to be forced through the ventilation tile, particularly in windy conditions.

A lower edge 315a of the baffle 315 is disposed below the second aperture 321 in order to restrict further the moisture flow.
In Figures 13 nd 14 a roof ventilation tile generally designated 410 comprises a tile member comprising an upper tile member 412 and a lower tile member 414.
The member 412 includes an upper surface 412 which can be disposed in the plane of a row of roof covering elements.
The member 412 is provided with a plurality of first apertures 416 which are juxtaposed in two rows; the apertures 416 enable air and moisture to flow into a ventilation chamber 412a defined between the members 411 and 412. It will be appreciated that it is not essential to provide two rows; one row, or more than two rows could instead be provided. If desired, a mesh (not shown) can be placed across the apertures 416 in order to help restrict the ingress of vermin and insects.
The member 412 also includes a wind deflector 418, and a peripheral flange 420. The peripheral flange 420 is provided with fixing apertures 422 through which fixing means (such as fixing nails) can be passed in order to secure the member 412 to the roof structure.
The member 414 is provided with a second aperture 424 which enables air to flow through the member 414. The aperture 424 is bordered by baffle means in the form of a duct 426 of substantially rectangular cross-section. The duct 416 restricts the flow of moisture to the interior of the roof structure.
The member 414 includes support means in the form of two moulded pillars 428. All the load of the member 412 is carried through the pillars 428.
A peripheral flange 430 is provided on the member 414; the peripheral flange includes fixing apertures 432 which can be disposed in alignment with the fixing apertures 422, so that the same fixing means can be used for the apertures 422 and 432.
In Figure 14 the distances designated "a", "b" and "c" may be substantially equal; typically the distance is about 2Omm.
Figures 15 to 17 show the ventilation tile 410 located in a roof structure. Although only one ventilation tile 410 is shown in the roof structure, it will be appreciated that a plurality of tiles would normally be provided.
The roof structure includes a plurality of plain tiles 434 arranged in a plurality of rows 436. Each tile 434 is secured to one of a plurality of battens 438; the battens 438 run transverse to a plurality of rafters 440, and the rafters 440 support the battens. Sarking felt 442 is disposed between the battens 438 and the rafters 440.
A fascia 444 is fixed to one end of the rafters 440, and a gutter 446 is mounted to the fascia 444; a soffit board 448 is also mounted to the fascia 444.
Insulation material 450 is provided in the interior 452 of the roof structure.
The roof ventilation tile 410 may take the place of, for example, one, two or three tiles 434 in the roof structure.
The adjacent tiles 434 in the same rot" 436 as the ventilation tile 410 are disposed on the peripheral flanges 420 and 430, thereby holding the ventilation tiles 410 in position.
The tiles 434 on the row 436 immediately above the ventilation tile 410 overlap the ventilation tile 410, but do not overlap the apertures 416.
As can be seen, the external surface 412a of the member 412 is disposed in the same plane as the rest of the tiles 434 in the row 436 in which the ventilation tile 434 is disposed.
The ventilation tiles 410 are secured to the battens 438 by fixing nails 54. It is possible to dispense with the fixing apertures 422 and 432, and the fixing nails 454. Instead the lower surface of the base 414 can be provided with formations (not shown) which can engage the upper edge of the battens 438 in order to hold the ventilation tile 410 in place.
In Figure 15, arrows G designate an air flow path through the ventilation tile 410. The ventilation tile 410 provides ventilation between the external environment to the interior 452 of the roof structure. A front edge 410a of the ventilation tile 410 acts as a baffle to deflect air flowing up the roof structure.
A hole (not shown) can be made in the sarking felt 442 in order to permit ventilation through the aperture 424 to the interior 452 of the roof structure. This may create a flap of sarking felt which can be folded upwards to deflect water.
If desired an extension sleeve can be provided in the hole of the sarking felt to direct air from the aperture 424 to the interior 452 of the roof structure.
Figures 18 to 22 show a fifth embodiment of roof ventilation tile 510. The tile 510 is similar to the tile 410. The roof structure shown in Figures 21 and 22 has been designated by the same reference numerals as that shown in Figures 15to 17.
The roof ventilation tile 510 comprises a tile member comprising upper and lower tile members 511 and 512. The tile members 511 and 512 define a ventilation chamber size therebetween.
A plurality of first apertures 513 are provided in the member 511, so that air between the external environment can communicate with the chamber 512a. A second aperture 514 is provided in the member 512, so that air can communicate between the interior of the roof structure and the ventilation chamber 512a.
The lower tile member 512 includes baffle means in the form of baffles 515 and 516. The baffle 516 is disposed immediately in front of the aperture 514.
The baffle 515 is provided with a lip 517 to enable moisture collecting behind the baffle 515 to be drained to a moisture outlet 517. The moisture outlet 517 is defined as a gap between the members 511 and 512.
The member 512 is provided with a flange 518 to enable the tile 510 to be retained in the roof structure, for example by fixing with nails.
As shown in Figures 21 and 22 the member 511 has an external surface 511 which is disposed in the plane of the row 436 of roof tiles 434.
It will be observed that the tile 510 is of a length such that it can extend between two rows of roof tiles.
This facilitates a construction in which there is no straight line air flow path between the apertures 413 and 414.
An air flow path through the tile 510 is shown by arrows H.
