Description

DESCRIPTION

[0001] The invention relates to a flashing system for a building, in particular for a roof or a wall, comprising at least one metal sheet for covering a part of the building, such as tiles of a roof or bricks in a wall.

[0002] Flashing systems typically include a impervious sheet of material, such as lead, placed in constructions to prevent water penetration or to direct flow of water. Flashing is used i.a. at roof hips and valleys, roof penetrations, joints between a roof and a vertical wall, and in masonry walls to direct the flow of water and moisture.

[0003] EP 2 447 437 discloses a flashing system according to the preamble of claim 1.

[0004] It is an object of the present invention to provide an improved flashing system.

[0005] To this end, the flashing system according to the present invention comprises the features of claim 1.

[0006] Thus, installation and/or replacement of the sheets is facilitated and/or handling of the sheets is improved, e.g. when a relatively soft metal such as lead is employed for the sheets.

[0007] In an embodiment, the sheet is at least locally slidable in the slotted element and/or the strip, in particular to allow slight local movement of the sheet in the longitudinal direction of the slotted element. Such slight relative movement reduces or avoids the forming of cracks resulting in particular from (cyclic) thermal expansion and/or contraction of the sheets.

[0008] In an embodiment, the strip is made from plastic or metal, preferably made from steel, preferably stainless steel, e.g. SS 316. Plastic and metal were found to provide sufficient stiffness and galvanic insulation of the sheet(s) from other metals, e.g. aluminium, in the flashing system or the building.

[0009] In an embodiment, the at least one sheet is made from lead and/or has a thickness of at least 1 mm, preferably a thickness in a range from 1 to 4 mm, and/or a length of at least 50 cm, preferably a length in range from 70 to 130 cm, and/or a height of at least 5 cm, preferably a height in a range from 10 to 60 cm.

[0010] According to the invention, the slotted element has an at least substantially circular cross-section open at at least one side to allow hooking in of the metal sheet.

[0011] To facilitate manufacture and reduce volume, in an embodiment, the slotted element is part of a profile, preferably an extrusion profile.

[0012] It is preferred that the slotted element is mounted on or part of a ridge beam or an element, e.g. the mentioned profile, defining the ridge beam and/or that the slotted element is mounted on or part of a rail slidingly accommodating an anchor and/or that the ridge beam and/or the rail are integrated in the same element, preferably an extrusion profile.

[0013] The invention further relates to a building comprising a flashing system as described above and mounted in a wall or on a roof, preferably beneath the ridge tiles of a roof and/or preferably on or as part of a ridge beam.

[0014] The invention will now be explained in more detail with reference to the Figures, which show embodiments of the present flashing system.

Figure 1 is a perspective view of a saddle roof comprising a flashing system according to the present invention.

Figure 2 is a cross-section of part of the roof shown in Figure 1.

Figure 3 is a perspective view of a sheet of a flashing system according to the present invention.

Figures 4 and 5 are cross-sections of the sheet in Figure 3 at different stages of manufacture.

[0015] Figures 1 and 2 show a saddle roof 1 comprising structural elements, in particular rafters 2 and a main beam 3, and roof slabs 4 fixed, e.g. nailed, to the rafters 2. Vertical battens 5 are fixed to the rafters 2, to the roof slabs 4 and/or to structural elements beneath, and horizontal battens 6 are fixed to the vertical battens 5 at some distance from the roof slabs to allow dirt and water to flow downwards and to improve ventilation. Rows of roof tiles 7 are supported on the horizontal battens 6.

[0016] An extrusion profile 8, e.g. made from aluminium, is mounted at the apex of the roof 1 via supports 9 and sideboards 10, which sideboards in turn are fixed to the rafters 2, e.g. via nails, screws or bolts. Ridge tiles 11 are positioned over the profile 8 to protect it from wind and rain and to prevent water from entering the space between the roof tiles and the roof slabs.

[0017] Lead flashing 12 is secured to the profile and extends between the upper row of tiles and the ridge tiles. The flashing is shown in more detail in Figures 3 to 5 and comprises a lead sheet 13. A stainless steel strip 14 is folded about one of the long edges of the sheet. The strip and the sheet sandwiched between it have been formed, e.g. bent or pressed, into the shape of a hook 15.

[0018] The ridge of the roof is provided, beneath the ridge tiles, with a slotted element. In this example, two slotted elements are defined in the extrusion profile, one on each side, and provide openings for receiving lead flashing 12.

[0019] In practice, after the profile has been installed and before the ridge tiles are installed, the sheets are hooked into the slots, e.g. inserted in the slots while held at a first angle and, once inserted, lowered to a secure position. If required, the metal sheets, e.g. lead, can than be pressed and shaped onto the tiles.

[0020] The invention is not restricted to the above-described embodiments which can be varied in a number of ways within the scope of the claims. For example, instead of a continuous slot, the slotted element can be provided with an intermittent slot or serial slots or openings effectively forming a slot or slots for receiving and securing sheets. In another example, the profile can comprise further features still, such as one or more rails or channels, slidably accommodating an anchor 17 for attaching a safety line (not shown). Details of suitable anchors can be found in WO 2012/056020.
