Definitions

  • the invention relates to an eave ventilation device for attachment to the eave, particularly to the upper side of a fascia.
  • Such devices are used for (rain)watertight finishing the eave area.
  • For use in building a first requirement is compliance with the legal standards and decisions. Additionally one should be able to securely and accurately place such a device, even less experienced builders, and possibly D.I.Y. enthusiasts should also be able to do so.
  • Such a device has to regulate the ventilation and air circulation of the eave portion and has to ensure connection of roof foil to the eave.
  • the invention provides a device that meets these demands as much as possible.
  • the invention provides an eave ventilation device for attachment to an eave, particularly to the upper side of a fascia, comprising a water discharging strip to be put on the roof boarding and on the upper side of the fascia, attachment means for attaching the device to the fascia, and ventilating duct forming means integrally formed with the strip which means are entirely situated at the upper side of the water discharging strip facing away from the roof boarding, which ventilating duct forming means also form supporting means for the roof tiles at the level of the fascia.
  • the device protects the eave well from (rain) water that either leaks through between the roof tiles, or blows up under the tiles. Additionally tilted placement of the bottom row of roof tiles is prevented because of the double function of the ventilating duct forming means.
  • a secure, oriented and stable (at nearly maximum distance from the upper end of the roof tile) support of the bottom row of roof tiles is namely formed without a separate tilting fillet or something like that being necessary.
  • the water discharging strip can be directly applied onto the boarding and fixed to a fascia.
  • the vapour stopping foil that is usually arranged directly on the outside of the boarding runs straight smoothly and continuously through on the water discharging strip up to the ventilating duct forming means.
  • a secure placement is furthermore possible, also by less experienced people, and the risk of damage is reduced because the device is formed as one unity. Additionally storage, transport, handling and logistics are easier because one type of device will suffice for all functions.
  • the device can be used particularly for buildings such as not-cold attics, that means attics that are (going to be) part of the living/working area.
  • Such a roof structure is provided with rafters having a fascia at the ends. At the fascia clamps may be arranged for retaining a roof gutter.
  • the ventilating duct forming means comprise spaced apart raised cross walls on the strip and one or more upper walls at the said walls substantially parallel to the strip.
  • the upper wall forms a support surface for the bottom row of roof tiles and replaces the bottom batten.
  • Perpendicular to the strip and parallel to the fascia a grid may be formed to prevent vermin or insects from reaching the roof boarding through the ventilating ducts.
  • the ventilating duct forming means are upwardly bounded by one or more upper walls.
  • the ventilating duct forming means are situated adjacent to the upper walls, so that the ventilating ducts are upwardly open.
  • the upper side of the ventilating duct forming means is provided with integrally formed flexible fingers extending from the upper side of the strip, and eaves board, for ensuring connection against the lower side of the roof tiles that are not level. As a result for instance birds cannot get between the roof tiles and the roof boarding in that way.
  • the strip For making a good connection to for instance a roof gutter possible, or preventing precipitation from running down the fascia, it is preferred to widen the strip over almost the entire length with a drop apron integrally formed thereto, hanging over the fascia.
  • the drop apron is a curved section retaining its shape that is integrally formed with the water discharging strip.
  • the drop apron preferably is provided with reinforcement means, preferably reinforcement ribs at the lower side facing the fascia.
  • the drop apron at the lower side facing the fascia, is provided with integrally formed vertical abutment surfaces for abutting the side of the fascia.
  • the reinforcement ribs also form vertical abutment surfaces.
  • the vertical abutment surfaces may also be formed because from the edge of the fascia the drop apron (in mounted situation of the device) comprises vertical portions that abut the fascia.
  • the water discharging strip preferably is provided with hinge means (preferably directly) along the ventilating duct forming means.
  • hinge means preferably directly along the ventilating duct forming means.
  • the hinge means that have been formed by a weakening, preferably are arranged in combination with the aforementioned flexible fingers and possible drop apron.
  • the fingers originate from the side of the ventilation means that are situated near the water discharging strip. Because of the fingers, and to a lesser extent the drop apron, the device could be difficult to stack.
  • the strip can be folded along the fingers a configuration is realised that is rather flat, and as a result easy to store. Additionally the device can be stacked well as a result.
  • the device according to the invention preferably is formed by injection moulding of poly olefin synthetic materials such as polyethene, or, which is preferable, polypropene. Polyester can also be used.
  • the device may also be formed by extrusion of for instance PVC.
  • the eave ventilation device 1 is shown in cross-section, arranged on a tile roof.
  • the eave ventilation device 1 can also be used very well on a slate-covered roof.
  • a roof with roof tiles 6 is built up from rafters 14 having a fascia 2 at the crosscut side of the rafters 14.
  • a roof boarding 4 has been arranged on the rafters 14 .
  • the eave ventilation device 1 is arranged to the upper side of the fascia 2, that may form the boundary (fascia) of a roof verge.
  • the water discharging strip 3 of the eave ventilation device 1 is here arranged on the roof boarding and its lower plane 30 lies flat on the upper side of the fascia 2.
  • the eave ventilation device 1 is here fixed by means of attachment means 16 on the upper side of the fascia 2 as can be seen in the figure.
  • the attachment means 16 may consist of a hole having a reinforcement around it so that as a result the device can be secured with nails without the device around it getting damaged.
  • the ventilating duct forming means 5 are formed by cross walls or partitions 7 that extend perpendicularly upward from the water discharging strip 3 above the fascia 2, in which at the upper side of the partitions 7 a continuous upper wall 8 is provided parallel to the upper side of the fascia 2.
  • the upper ends of the roof tiles 16a hook behind batten 17.
  • the lower ends of the bottom row of roof tiles 6a support on the upper wall 8 of the ventilating duct forming means 5, as a result of which a tilted position of said roof tiles is prevented.
  • the ventilating duct forming means 5 are therefore situated just above the fascia 2, and near the end of the bottom row of roof tiles 6a.
  • a foil On the outside of the roof boarding 4 a foil has been arranged, which runs smoothly and almost straight over the water discharging strip 3 up to the ventilating duct forming means 5.
  • the ventilating duct forming means 5 ensure that underneath the roof tiles 6, 6a ventilation air can be carried through and over the roof boarding 4 so that no accumulation of moisture can arise here.
  • a ventilation slit of at least 25 mm continuously is mandatory.
  • Per running meter a ventilation surface of 250 mm 2 is created as a result.
  • an eaves board 9 On the upper side of the ventilating duct forming means 5, that means at the upper wall 8, an eaves board 9 has been arranged consisting of flexible fingers. Said eaves board closes off the remaining space between the lower side of the roof tiles (having an undulating lower side or one that is not level) and the roof boarding from birds and the like. In the figure the fingers are bent backward. However it is also possible to bend the fingers forward. Furthermore the ventilating means may be provided in an as it were inverted manner, in which case the upper wall 8' and the fingers 9' are situated at the roof side instead of at the gutter side. The upper wall 8' then preferably extends up to a vertical plane through the lower end of the inclined portion of the strip 3 (see dotted lines in figure 2).
  • the water discharging strip 3 merges into a drop apron 10.
  • the drop apron 10 is formed by a curved section retaining its shape which at the lower side, that means the side facing the fascia, is provided with reinforcement ribs 11 that also ensure a placement plane and an abutment plane as well against the vertical outer plane of the fascia 2 and as a result give strength and support to the drop apron 10.
  • the drop apron 10 may debouch in a roof drain gutter 13, as can be seen in the figure.
  • Said roof drain 13 can be attached to the fascia by means of for instance attachment brackets 18.
  • the various parts of the eave ventilation device 1 are formed as one unity from preferably a synthetic material preferably by means of injection moulding.
  • hinge means 12 are indicated. Said hinge means 12 are realised here by arranging a weakening over the entire length at the lower side. As can be seen the water discharging strip 3 as a result connects perfectly to the roof boarding 4.
  • FIGS. 1 and 2 show a view in perspective of the embodiment of the eave ventilation device 1 according to figure 1.
  • the ventilating duct forming means 5 in this embodiment are formed by partitions 7, at least almost perpendicular to the water discharging strip 3 and almost perpendicular to the upper side above the fascia 2.
  • the upper wall 8 has been integrally formed on said partitions 7, the eaves board 9 being situated at the upper side.
  • Figure 3 shows a cross-section of an alternative embodiment of the eave ventilation device 1 according to the invention.
  • the ribs 11 parts of the drop apron 10 are staggered in height with respect to each other in order for amongst others forming abutment planes 19.
  • the inclined walls 22 and the inclined walls 23, 24, 25 improve the air flow (spoiler) and make it possible to nest the device 1 when stacking. This is improved because the hinge 12 is situated below the roof end of the upper wall 20, so that the inclined portion of the strip 3 can be folded up against the fingers 9.
  • parts 19 of the drop apron 10 immediately after the fascia 2 run almost straight down along the fascia 2 to give support to the drop apron 10 against the fascia 2, instead of or possibly adjacent to ribs 11 of the embodiment according to figure 1. Because of the formation of staggered parts, parts of the eave ventilation device can be nested and stacked.
  • figure 4 a view in perspective of the eave ventilation device 1 of figure 3 can be seen, also without roof tiles and roof structure.
