Definitions

  • the present invention relates to a multilayer roofing element according to the introduction of claim 1.
  • Such a roofing element is generally known in the form of a course of bitumen provided with a combustible foil on the back side.
  • the primary purpose of the combustible foil is to prevent abutting layers of a roll of bitumen from sticking together.
  • bitumen on the underside of the course will melt, causing the roofing elements to bond to the slabs of bitumen that are fixed to the roof and causing the overlapping portions of two adjoining courses to bond together.
  • the combustible foil will burn during said heating, so that the overlapping portions of bitumen (courses and slabs) are no longer separated by the foil and said portions can bond together.
  • a drawback of these roofing elements is the fact that they need to be heated not only at the location of their overlapping portions but also at the locations of the slabs that are fixed to the roof in order to provide an adequate bond. Since the locations of the slabs are difficult to distinguish, if at all, the course of bitumen needs to be heated over their entire width and length. Moreover, the slabs are covered by the roofing elements after heating of the elements, so that it is difficult to distinguish the locations of these slabs and to check whether the roofing elements have actually bonded thereto.
  • French patent application FR 2800766 A1 discloses a course of waterproof material comprising an upper layer of bituminous material and a fixing layer suitable for engagement with the hook side of a Velcro element.
  • Two adjacent courses are attached to each other and to the roof by means of a small strip having an upper layer of Velcro for cooperation with the back layer of the courses and comprising an adhesive backing for attachment to a roof.
  • a traditional joint covers the upper side of neighbouring roofing elements and the joint there between.
  • a disadvantage of this known roofing element is that it requires two additional waterproof layers to ensure a leakage free roofing.
  • a shingle as a roofing element formed from an underlying flexible substrate material which bears a coating of asphalt of each major surface thereof.
  • the asphalt coatings in turn each bear a particular of sand layer embedded thereon.
  • On the upper surface of the shingle is fixed a longitudinally extending strip of exposed seal down asphalt.
  • At the lower surface is fixed a small part (5 cm x 5 cm) of the hook side of a hook and loop faster for cooperation with non woven material provided on a roof.
  • DE 197 52 819 A1 discloses a heat insulation element having an insulation layer, on the upper surface of which a woven layer provided with hooks is attached by sewing. The hooks cooperate with a non woven layer of a cover element.
  • the Velcro elements and their back side of the bitumen adhere together directly after making contact with each other. Consequently it is no longer necessary to distinguish the locations in question.
  • the bond between the courses of bitumen and the Velcro elements fixed to the roof is effected automatically upon placement of the courses of bitumen.
  • the Velcro elements are provided with a protective layer upon being fixed to the roof, which layer is removed after a course has been positioned, so that the hook side and the loop side of the Velcro elements can only be made to adhere to each other at that point in time.
  • the adhesion of the fixing layer, once effected, is sufficiently strong from the outset.
  • Velcro connections An inherent characteristic of Velcro connections is that the bond only becomes stronger as time passes by, because an increasing number of fibres and barbs of the two Velcro elements will engage one another. Another advantage is that the tensile strength and thus the adhesion can be predetermined by selecting a particular specification of a Velcro element (the number of hooks per cm 2 ).
  • the hook side is relatively expensive in comparison with the material of the loop side that is to be engaged by the hook side of a Velcro element.
  • the comparatively expensive hook side is locally fixed to a roof, and the comparatively inexpensive "loop side" is provided on the entire back side, or at least on a large part of the back side, of the roofing element.
  • the strip of at least 1 centimetre that is thus kept free from the material of the fixing layer on the back side of the bitumen can be used for overlapping an adjacent course of bitumen.
  • the strip of bitumen at the circumferential edge that is free from the fixing material has a width of at least 3 centimetres, preferably 5 centimetres and even more preferably 7 centimetres, a better overlap and thus a better adhesion between two adjacent courses can be realised. After all, the greater the overlap, the larger the area of adhesion between the two layers.
  • the strip can be easily fused to the portion of the adjacent course that is overlapped by the strip in the conventional manner by means of a burner, but it is also possible to fuse the strip and the portion overlapped by the strip together by means of hot air or induction.
  • the fixing layer preferably comprises a nonwoven fibre material.
  • Nonwoven fibre material is very suitable for use as the loop side for engagement with the hook side of a Velcro element, and in addition it can be provided on the back side of a course of bitumen in a simple and inexpensive manner.
  • the fixing layer preferably comprises polypropylene and/or polyester. These materials are comparatively inexpensive and have the required characteristics for functioning as the loop side for engagement with the hook side of a Velcro element, so that a proper adhesion between the hook side and the fixing layer is realised.
  • the fixing layer extends to a distance of at least 1 cm from the long side of the circumferential edge of the coating.
  • the long side can be used for overlapping the bitumen of an adjacent roofing element along the length thereof.
  • a better adhesion between two adjacent courses can be obtained if the strip that is free from the fixing material has a width of at least 3 centimetres, preferably 5 centimetres and even more preferably 7 centimetres.
  • the fixing layer extends to a distance of at least 1 centimetre from at least substantially the entire circumferential edge of the roofing element.
  • a strip width of 3 centimetres preferably 5 centimetres and more preferably even 7 centimetres may be kept free from the fixing material.
  • an intermediate layer is provided between the coating and the fixing layer.
  • Said intermediate layer is a layer which is provided on one side of a (conventional) course of bitumen so as to prevent the upper side and the underside of the course from undesirably sticking together during storage, for example during storage in the form of a roll.
  • the original layer behaves as a bonding layer between the bitumen and the nonwoven fibre material.
  • the intermediate layer preferably comprises a foil that is provided with perforations.
  • the intermediate layer preferably comprises polyethylene.
  • Polyethylene foil has proven its worth as a carrier for a bituminous roofing element in practice and, in addition, it can be readily bonded to the material, for example polypropylene in or polyester, of which the fixing material of the fixing layer is composed.
  • the bituminous coating has a thickness of less than 3.8 mm, preferably less than 3.5 mm.
  • Traditional roofing elements that are installed on a roof in a manner as known so far have a thickness of at least about 4.0 mm in order to provide a sufficiently watertight and strong bond.
  • a thickness of as little as 3.0 mm will suffice, which makes it possible to realise a significant saving in costs. This is possible because the roofing element need not be locally heated, so that there is no risk of the bitumen locally becoming thinner due to melting.
  • this also provides a saving in storage and transport costs.
  • a saving in installation costs can be realised, because a greater roll length, which is bound to a maximum weight in accordance with safety, health and welfare legislation, may now be used, thus making it possible to work more efficiently.
  • identification means are provided, preferably in the form of a chip, for identifying the roofing element in question. Identification of roofing elements is advantageous in order to be able to trace roofing elements from a specific production cycle, for example in the case of complaints. Furthermore this makes it possible to prove that roofing elements, whether or not installed on a roof, form part of a stolen batch.
  • the identification means comprise a transmitter for reading of the identification from a remote location. This makes it readily possible to trace stolen roofing elements from a remote location.
  • the present invention further relates to a method for manufacturing a multilayer roofing element as described above, comprising the steps of applying a course of a bituminous layer to a layer of a nonwoven material, wherein a strip of bitumen of at least 1 centimetre, seen from the edge of the course, is kept free from nonwoven material on at least one side of the course, and bonding together the bitumen and the nonwoven material.
  • the strip has a width of 3 centimetres, preferably 5 centimetres and even more preferably 7 centimetres so as to realise a proper bond between two adjacent courses of bitumen.
  • a method for manufacturing a multilayer roofing element in the form of a course of bitumen to which a layer of a material other than bitumen is applied by laying out a course of a bituminous layer and applying the layer of a material other than bitumen thereto is known.
  • a course of a multilayer roofing element is produced in a more or less continuous process by rolling, but the method as described in the preceding paragraph has this advantage that it makes it possible to provide a nonwoven material in a precise and desired manner.
  • a strip might be kept free on a long side of the bitumen, because the course is passed through a machine in a direction parallel to the long side.
  • an at least substantially rectangular course of bitumen is laid out on the surface to be covered.
  • a rectangular course thus formed can be readily processed as a roofing element.
  • connection if a strip of bitumen of at least 1 centimetre, seen from the circumferential edge of the course, is kept free from nonwoven fibre material when carrying out the step of applying a nonwoven material to the back side of the bituminous layer.
  • a course is produced which has an edge that is free from nonwoven fibre material along the entire circumference thereof, and which is thus suitable for overlapping and bonding to an adjacent course when the roofing element is installed on a roof as discussed in the foregoing in relation to the roofing element.
  • a fixing layer is applied to the side of the nonwoven fibre material that is to be applied to the bituminous layer prior to the step of applying a nonwoven fibre material to the bituminous layer, or a nonwoven fibre material is applied to the fixing layer prior to the step of applying the nonwoven fibre material to the bituminous layer.
  • bituminous layer on the one hand and the bonding layer with the fibre material present thereon on the other hand are separately produced, after which the separately produced layers can be bonded together. It may be advantageous for production reasons to produce the two layers separately, for example in order to prevent fibre material from finding its way between the bitumen and the fixing layer.
  • Another advantage is that it is possible to apply a specifically selected fixing layer to the back of the course of bitumen at a comparatively late stage of the production process, which may have logistics advantages, among other advantages.
  • the present invention further relates to a method for covering a roof with roofing elements, comprising the steps of fixing of Velcro elements to a roof to be covered and attaching a roofing element according to the first aspect of the present invention to a number of Velcro elements fixed to the roof with a side of the roofing element that is provided with a nonwoven fibre material.
  • a method for covering a roof with roofing elements comprising the steps of fixing of Velcro elements to a roof to be covered and attaching a roofing element according to the first aspect of the present invention to a number of Velcro elements fixed to the roof with a side of the roofing element that is provided with a nonwoven fibre material.
  • connection if subsequently, in a next step, another roofing element is attached to a number of Velcro elements with the side that is provided with a nonwoven fibre material, with a strip of the roofing element that is free from fixing material partially overlapping a previously installed roofing element.
  • the Velcro elements are fixed to the roof in staggered relationship. Said staggered arrangement is possible because substantially the entire course of bitumen of the roofing element is provided with a material which can be engaged by the Velcro elements that are fixed to the roof. Once the roofing elements have been installed, it is no longer necessary to distinguish the location of the Velcro elements, because there is no need for a subsequent treatment, such as heating the locations in question as is done in the prior art, wherein the roofing elements must be fused together with slabs of bitumen that are fixed to the roof.
  • the aforesaid staggered arrangement makes it possible to realise a better spreading of the points of attachment of the roofing elements over the roof and thus provide providing a better attachment of the roofing element to the roof.
  • Figure 1 schematically shows a bottom view of a course 1 of a roofing material comprising a bituminous layer 2, which is largely covered with a nonwoven fibre material 3.
  • Figure 2 is a cross-sectional view along the line II-II in figure 1 , showing the bituminous layer 2 with a layer of a separating foil 4 provided with perforations 5, which functions as an intermediate layer, applied thereto, on which a layer of a nonwoven fibre material 3 is present.
  • FIG. 3 is a schematic sectional view of a roof with a roofing element 11 installed thereon.
  • a screw 15 extends through the hook-side Velcro element 14 and the expanded polystyrene, which screw has been screwed into the hard surface.
  • the screw 15 is surrounded by a mushroom-shaped element 16 of plastic material, on which the head of the screw engages.
  • Present on the expanded polystyrene 13 and the hook-side Velcro elements 14 is a roofing element 11.
  • a bottom side is shown of a roofing element according to the present invention in the form of a course 1 of a roofing material comprising a bituminous layer 2, a separating foil (not shown in figure 1 ) and a layer of a nonwoven fibre material.
  • the layer of nonwoven fibre material 3 extends substantially the entire length and substantially the entire width of the bituminous layer 2, and a strip of bitumen 2 has been kept free from the nonwoven fibre material 3 (in the present example) at one of the long sides and one of the short sides of the course 1.
  • the proportions between the length and the width of the course 1 and the width of the strips that are kept free are schematically shown in figure 1 , these proportions need not correspond to the proportions of a roofing element to be used in practice, in fact said proportions need not even be nearly the same.
  • the width of the strip of bitumen 2 that are kept free will be selected so that it suffices for overlapping an adjacent course of bitumen when used on a roof, so that said strip can be fused together with the adjacent course, for example by means of a burner. It is also possible, however, to bond overlapping strips according to the present invention together by means of hot air or induction.
  • Figure 2 is a - likewise schematic - cross-sectional view along the line II-II in figure 1 .
  • the course 1 is shown in upside-down view.
  • the layer of nonwoven fibre material 3 is separated from a bituminous layer 2 in the present embodiment by means of a separating foil 4 provided with perforations 5.
  • This strip of bitumen 2 on the left-hand side of figure 2 that is free from the nonwoven fibre material extends to above (and, when used on the roof, below) the layer of nonwoven fibre material 3. This is not a requirement, however, but it is preferred in order to be able to realise sufficient tensile strength over the entire area.
  • the perforations 5 in the separating foil 4 allow bitumen to penetrate into the nonwoven fibre material 3 through the perforations when the course 1 is being heated for bonding the nonwoven fibre material 3 and the bitumen 2 together. Although said penetration only takes place to a limited extent, it provides an adequate bond between the two layers 2 and 3.
  • the separating foil 4 may furthermore help to prevent two opposing layers of bitumen from adhering to each other during storage of bitumen 2, for example in the form of a roll, prior to the provision of the nonwoven fibre material 3, as a consequence of which the roll of bitumen cannot be unrolled any more, at least not without damaging the bitumen.
  • FIG. 3 shows the use of a roofing element 11 according to the present invention on a roof.
  • a vapour-inhibiting layer 12a with a layer of insulating material 13 of, in this example, polystyrene (also PIR or PUR may be used), is to that end installed on a hard surface 12 by screwing screws 15 having a large, flat head into the hard surface 12, in this case via a mushroom-shaped element 16 having an internal diameter which is sufficiently large for the shank of the screw 15 to extend therethrough but which prevents the head of the screw from penetrating into the inner circumference of the stem of the mushroom-shaped element 16.
  • the head (not shown) of the screw may be countersunk in the mushroom-shaped element 16.
  • the shaft of the mushroom-shaped element 16 is passed through the hook side of a Velcro element 14, in such a manner that the upper side of the mushroom-shaped element 16 fixes the hook-side Velcro element 14 with respect to the surface of the insulation material.
  • the nonwoven fibre material (not shown in figure 3 ) will be engaged by the hook-side Velcro elements, as a result of which a connection between the nonwoven fibre material and the hook-side of forming Velcro element is automatically effected.
  • Velcro elements the mutual bond between the hook side and the nonwoven fibre material will be effected directly upon making contact.
  • the hook side of the mushroom-shaped element 16 is provided with a protective foil, which is not removed until the roofing element is correctly oriented.
  • the contact between the roofing element 11 and the mushroom-shaped element 16 that is thus made possible directly leads to a good bond between the two.
  • the engagement between the hook-side Velcro element and the nonwoven fibre material will become stronger.
  • the strength of the connection can be predetermined, inter alia, by the selection of materials, and Velcro elements comprising comparatively many hook elements and many loop elements will form a comparatively stronger connection than Velcro elements comprising relatively few hook elements and relatively few loop elements per unit area.
  • nonwoven fibre material any other material that is capable of providing a loop side of a Velcro element. It is of course possible to mutually exchange Velcro elements with a side and Velcro elements with a loop side, in the sense that the elements having a hook side are provided with a loop side and vice versa.
