Description
SPECIFICATION
Eaves apparatus
This invention relates to eaves apparatus for the eaves of a roof of a structure.
Modern roof constructions of slates or tiles over a layer of impervious roofing felt almost hermetically seal the roof space of structures such for example as houses. Ever higher standards of loft insulation ensure that the environment in the roof space becomes colder and colder. Combined with lack of ventilation, modern roof constructions greatly increase the likelihood of condensation in the roof space, with consequent problems of decay and rotting structural woodwork.
Modern roof constructions may also suffer from an associated problem of water forming in pockets if the roofing felt becomes buckled behind the fascia board. Eventually the water may find its way into the roof structure, again causing problems of decay and rotting of structural woodwork. This problem of retention of water in pockets is often known as ponding.
A yet further problem with modern roof constructions is that the roofing felt ofter overhangs the fascia board and thus forms a flap which may move in the wind and which may eventually wear through at the point of contact of the flap with the fascia board. The felt then falls behind the fascia board and wind-blown rain and melting snow that have eluded the primary roof covering are led into the building rather than into the gutter.
In order to overcome the above problems, different types of eaves apparatus have recently become known but these are not satisfactory, for example because they use relatively narrow anti-ponding sheet material which can still give ponding problems and/or the anti-ponding sheet material is not arranged to be fixed at its upper end which can require different widths of the sheet material for different roof pitches, or which with steep pitched rooves can cause the upper edge of the sheet material to foul roof rafters, or which with shallow pitched rooves can cause the upper edge of the sheet material to clear the roof rafters and so leave the roofing felt insecurely supported.
It is an aim of the present invention to provide eaves apparatus which operates or reduces the abovementioned problems.
Accordingly, this invention provides eaves apparatus for the eaves of a roof of a structure, which eaves apparatus comprises a ventilating and fixing strip which is for attachment to the top of a fascia board located in the eaves of the roof, sheet material which is of a sufficient width to extend between the ventilating and fixing strip and a lowermost roof batten adjacent the eaves, and fastener means for fastening the sheet material to the ventilating and fixing strip and also for fastening the ventilating and fixing strip to the fascia board, the sheet material being sufficiently stiff to prevent excessive sagging between the lowermost roof batten and the ventilating and fixing strip.
The ventilating and fixing strip may be provided with apertures, mesh, net or a semi-permeable membrane for affording the ventilation.
The apertures may be of any desired shape, for example slots.
The ventilating and fixing strip may be made of a plastics material. Presently preferred plastics materials are polythene and polyvinyl chloride. If desired, the ventilating and fixing strip could be made of a metal, for example aluminium.
Preferably, the ventilating and fixing strip is provided with reinforcing pillars.
The reinforcing pillars may be integrally formed with the ventilating and fixing strip.
The eaves apparatus may include the fascia board.
The ventilating and fixing strip may include an integrally formed fascia portion.
Usually, the sheet material will be separately formed from the ventilating and fixing strip.
The sheet material may be made of any desired material but it is preferably made of a plastics material. The plastics material may be polythene or polyvinyl chloride. Metals may also be employed for the sheet material, for example aluminium.
An embodiment of the invention will now be described solely by way of example and with reference to the accompanying drawings in which:
Figure 'is a side view of eaves apparatus in accordance with the invention; and
Figure 2 is a perspective view of the eaves apparatus shown in Figure 1, but looking from the front and the other side.
Referring to the drawings, there is shown eaves apparatus 2 for the eaves 4 of a roof of a structure.
The eaves apparatus 2 comprises a ventilating and fixing strip 6 which is for attachmentto the top of a fascia board 8 located in the eaves 4 of the roof. The eaves apparatus 2 also comprises sheet material 10 which is of a sufficient width as shown to extend between the strip 6 and a lowermost roof batten 12 adjacent the eaves 4. The eaves apparatus 2 further comprises fastener means in the form of nails 14 for fastening the sheet material 10 to the strip 6 and also for fastening the strip 6 to the fascia board 8. The nails 14 may also be employed for fastening the sheet material 10 underneath the batten 12. As shown, roofing felt 16 runs down the roof and under the batten 12 but over the sheet material 10. The end 18 of the roofing felt 16 is thus supported by the sheet material 10.The sheet material 10 cannot sag because it is secured along its top edge by the batten 12 and along its bottom edge by the nails 14 to the strip 6. The sheet material 10 is sufficiently stiff to prevent excessive sagging between the batten 12 and the strip 6 and thus ponding is avoided.
The strip 6 is provided with ventilating slots 20 anc it is preferably made of a plastics material such for example as polythene or polyvinyl chloride. The strip 6 is provided with spaced apart reinforcing pillars 22. Depending upon the method of manufacture of the strip 6, the pillars 22 may be separately formed from or integrally formed with the strip 6.
The fascia board 8 supports a gutter 24 as shown in Figure 1, the gutter 24 being shown spaced apart from the fascia board 8 for ease of illustration.
The strip 6 is provided with an integrally formed fascia portion 26 which seats along the face of the fascia board 8 as shown. The gutter 24 can be secured to the fascia portion 26 or, alternatively, to the fascia board 8 as may be desired.
The nails 14 used for fastening the strip 6 to the fascia board 8 advantageously pass through the pillars 22. The upper surface of the strip 6 may be provided with a locating groove 28 for facilitating the correct location of the nails 14
The strip 6 may be mounted on top of fascia boards 8 of new or existing buildings. The eaves apparatus 2 enables ventilation to be provided that complies with the requirements of F5 of Building
Regulations 1981. The sheet material 10 prevents or reduces the ponding as mentioned above, and the sheet material 10 also supports the end 18 of the roofing felt 16so that this end 18 is not available to flap loosely over the end of the strip 6 and thus eventually wear and let in wind-driven rain and snow as mentioned above.
The strip 6 is advantageously made of high density polythene or other high density plastics material such as polyvinyl chloride so that the strip 6 can easily be fixed by the nails 14 as shown. It is not necessary to preform apertures and the strip 6 is corrosion resistant if it is made of a plastics material.
The use of the pillars 22 produce a rugged construction which is resistant to accidental damage during fixing. The sheet material 10 is of considerable width, for example approximately 40cm, in order to support the edge 18 of the roofing felt 16 as far back as the last fixing point which is the batten 12 which may be regarded as the lowest tile batten. The sheet material 10 is sufficiently flexible to accommodate all roof pitches but it is fastened at both ends as mentioned above to provide firm support for the roofing felt 16. The sheet material 10 and the strip 6 may be provided in any required lengths and long lengths will speed installation.
It is to be appreciated that the embodiment of the invention described above with reference to the accompanying drawings has been given by way of example only and that modifications may be effected. Thus, for example, screws or other fasteners may be employed instead of the nails 14. the illustrated pillars 22 are hollow cylindrical pillars 22 but other types of pillars may be employed if desired. The sheet material 10 is shown as being separately formed from the strip 6 but it could be integrally formed with the strip 6 if desired. Similarly, the fascia board 8 could be integrally formed with the strip 6. The invention also extends to the various illustrated components of the drawings taken separately or in any combination. The batten 12 can extend across any desired number of roof rafters 30.
