Abstract
Description
- The present invention relates to a roof tile, which is intended for covering a roof by combining several roof tiles, and which roof rile includes, as various layers,
- a support layer,
- an insulating layer on both sides of the support layer,
- a surface layer on the opposite surface of the first insulating layer to the support layer, and
- a protective layer on the opposite surface of the second insulating layer to the support layer.
- Various kinds of tiles exist for covering a roof. One known type of roof tile is flexible and the roof tiles are set to partly overlap, in order to form a nearly two-layer roof. Such a roof tile includes a support layer, on both sides of which is an insulating layer. The insulating layer usually consists of bitumen. On the upper surface of the roof tile, there is, in addition, a surface layer, which has several alternative colours, in order to create the desired appearance on the roof. On the surface of the lower insulating layer, there is, in addition, a protective layer, to prevent the tiles from adhering to each other during storage and transportation, and to prevent adhesion to the manufacturing equipment during the manufacturing process. However, an adhesive layer is further arranged on the undersurface of the roof tile, on top of which there is then a plastic film preventing the roof tile from unintentionally adhering to the base or to the other roof tiles, as well as preventing it from adhering to the manufacturing equipment during the manufacturing process. However, when the roof tile is installed, the plastic film is removed, so that the roof tile adheres to the part of the roof tile under it that overlaps it.
- In known roof tiles, the insulating layers are formed of rubberized bitumen, on which sand, for example, natural sand, is sprinkled to form a protective layer. A great deal of sand should be used to achieve a sufficiently effective protective layer. Especially during manufacture, the sand drops off along the process, leading to quartz dust in the production space and thus in the air breathed, increasing the risk of exposure to it. The sand and dust also increase the need for cleaning and can cause production breaks.
- The invention is intended to create a new type of roof tile, which is easier to handle than previously, and which does not have the drawbacks of the prior art. In addition, the invention is intended to create a new type of method for manufacturing roof tiles, which is simpler and more reliable than previously, but which can also be adapted more versatilely than previously. The characteristic features of the roof tile according to the invention are stated in the accompanying Claim 1. Correspondingly, the characteristic features of the method according to the invention are stated in the accompanying Claim 8. In the roof tile according to the invention, new and surprising types of layers are used. Thus, the roof tile is more user friendly than previously and considerably lighter than previously. At the same time, the roof tile can incorporate new properties. The production method can also be adapted more freely than previously.

Figure 1b shows oneroof tile 10 according to the invention. Other models of roof tile also exist, though the model shown here, along with its variations, appears to be the most usual. When using a roof tile, the idea is to cover theroof 11 by combiningseveral roof riles 10.Figure 1a shows the initial stage of roofing. At least at the eaves of theroof 11, astrip 12 is first of all installed, with properties and colour corresponding to those of theroof tile 10. Often, a base membrane (not shown) must also be used over the entire area of the roof. The roof tiles 10 of the first row are installed on top of thestrip 12 and nailed onto theroof 11, according toFigure 1a . Other attachments can also be used in place of nails. If theroof tile 10 has a separate adhesive layer, the film-likepeelable structure 13 is removed form its undersurface, prior to the installation of theroof tile 10. The roof tiles of the next row are installed to partly overlap the previous row and offset relative to the tiles in it. The finished roof then gains a shingle-like appearance and the joints of the roof tiles set end to end are hidden under the next row. In addition, the roof becomes almost two-layer. In addition to the hidden nailing, the roof tile adheres to its base, or to the area of the roof tile under it, from which the peelable structure was removed prior to installation. -
Figure 1d shows a cross-section of one embodiment of the roof tile according to the invention. The roof tile is formed of layers attached to each other, which are shown here clearly enlarged, for reasons of clarity. The various layers of theroof tile 10 include asupport layer 14, which is, for example, of glass-fibre felt or polyester fabric. Next are insulatinglayers support layer 14. Usually, the insulating layer is of bitumen or rubberized bitumen. Then there is asurface layer 17 on the surface of theinsulating layer 15 opposite to thesupport layer 14, which determines the appearance of the roof. The surface layer is usually of a mineral material, such as slate or mineral chips. On the other side of the support layer is aprotective layer 18, which is on the opposite surface of theinsulating layer 16 to thesupport layer 14. The protective layer is usually spread over the entire area of the roof tile and prevents the roof tile from unintentionally adhering to the manufacturing equipment, such as rollers, during manufacture. The protective layer also prevents the roof tile from unintentionally adhering to its base or to other roof tiles during transport and storage. - According to the invention, the
protective layer 18 is surprisingly formed of afilm 20 arranged permanently on theroof tile 10, which covers entirely the opposite surface of the second insulatinglayer 16 to thesupport layer 14. In other words, the sand is replaced with a film, so that the problems previously caused by the sand can be completely avoided. At the same time, the mass of the roof tile is significantly reduced. Nowadays, the mass of a sales package containing 22 roof tiles is about 25 kilograms, depending on the various surface-chip alternatives. Thanks to the film, two to five more roof tiles can be packed in a sales package of the same weight. Thus, the mass of a single roof tile is about 10 % less than that of a known tile. Correspondingly, it is possible to load 42 sales packages on a pallet, in place of the previous 36. This significantly reduces handling and transport costs. In addition, the film improves the watertightness of the roof tile, while its other properties remain unchanged. In practice, the resistance of the roof tile to water pressure improves. In other words, the technical properties of the roof tile improve. On the other hand, a sales package containing the known number of roof tiles will weigh less than before, thus facilitating handling of the packages on the roof and reducing storage and transport costs. - The film can be made from various kinds of material. The film is preferably made from a plastic film, which is light and thin. The plastic film can be, for example, polyethylene or polypropylene, or a corresponding material in a roll. On the other hand, by manufacturing the film from a woven fabric, the properties of the roof tile will be further improved as the woven fabric increases the strength of the roof tile. A combination of a plastic film and a woven fabric can also be used. The main task of the film is to act as a protective layer, so that even very thin films can be used. In practice, the thickness of the film is 0, 005 - 0,3 mm, preferably 0, 005 - 0,2 mm. A plastic film will generally be thinner than a woven fabric. The film prevents the insulating layer from adhering to the bitumen. Even a thin film will function well, if the film is essentially impenetrable to the material of the insulating layer. However, the film adheres to the bitumen in the manufacturing process and remains permanently in the structure of the roof tile. Normally, an adhesive layer, covered with a peelable plastic, can be arranged on top of the film. Thus, during installation, when the peelable plastic is removed, the roof tile adheres to both its base and to the roof tile underneath it over the entire adhesive layer. If necessary, an adhesive surface can also be arranged on the side of the surface layer.
- Thanks to the aforementioned adhesive layer, the roof tiles that are installed to partly overlap each other adhere to each other, thus achieving a watertight and durable roof. Thus an
adhesive layer 19, which is usually of rubberized bitumen and is applied on top of the protective layer, can be arranged on the opposite surface of theprotective layer 18 to the second insulatinglayer 16. Again, in order to prevent unintentional adhesion, apeelable structure 13 is arranged detachably on the opposite surface of theadhesive layer 19 to theprotective layer 18. Usually, thepeelable structure 13 is of silicon film, which is removed from the surface of the adhesive layer prior to the installation of the roof tile 10 (Figure 1c ). The peelable structure can also be come other membrane, which is processed in such a way that it can be detached from the surface of the adhesive layer.Figures 3a - c show in greater detail various embodiments of the roof tile according to the invention. According to the invention, the adhesive layer covers part of the surface area of the roof tile, or essentially the entire surface area of the roof tile. InFigure 3a , anadhesive layer 19, which cover part of the surface area of theroof tile 10, is applied on the surface of thefilm 20. InFigures 3a and 3b , only part of thepeelable structure 13 is shown, for reasons of clarity. In the embodiment ofFigure 3b , theadhesive layer 19 surprisingly covers the entire surface area of theroof tile 10. In that case, the roof tile adheres entirely to its base. On the other hand, the adhesive layer can be entirely omitted, in which case the undersurface of theroof tile 10 will be formed by thefilm 20 according to the invention. A roof tile of this kind can be attached by welding or gluing. - Thus, according to the invention, a film is formed, which is arranged permanently on the entire opposite surface of the second insulating layer to the support layer. In addition to improving the properties of the roof tile, advantages are also gained in manufacturing.
Figures 2a and 2b show schematically the manufacture of the roof tile. Here, the production process proceeds from left to right, and from up to down. In the manufacture, theroof tile 10 is formed from various layers, in such a way that insulatinglayers like support layer 14. InFigure 2a , thesupport layer 14 is fed to the process and the first insulatinglayer 15 is applied to its upper surface and the second insulatinglayer 16 to its undersurface. After this, surface chips are sprinkled onto the opposite surface of the first insulatinglayer 15 to thesupport layer 14, in order to create asurface layer 17. Next, afilm 20, on top of which anadhesive layer 19 is applied to that part of the roof tile on which adhesion is required, is run onto the surface of the second insulatinglayer 16. Alternatively, the entire application of the adhesive layer can be omitted (Figure 3c ). The film is arranged when the second insulating layer is hot, so that the film adheres firmly to the blank. Next, apeelable structure 13 is arranged detachably on the opposite surface of theadhesive layer 19 to theprotective layer 18. In practice, in the process the necessary number of adhesive bitumen strips, which are covered with silicon plastic, are applied on top of the film. Finally, the blank 21 is cooled, after whichroof tiles 10, which are bundled and packaged, are cut from the blank 21. In the process, four roof tiles next to each other are cut from a blank about one-metre wide.Figures 2a and 2b show the devices belonging to the process schematically as simple boxes. For example, the insulating layers and adhesive layers are applied as the blank travels through a bitumen cauldron. - The sand that was previously put on the protective layer was sprinkled on the insulating layer while the bitumen was hot. According to the invention, instead of sand the film is run onto the surface of the bitumen. This avoids quartz dust spreading into the production facility. At the same time, the watertightness of the roof tile is improved. Naturally, the film described above is used in the process. The finished roof tile is about three-millimetres thick and has a length of about 1000 mm and a width of about 320 mm. Of course, the dimensions of the roof tile can vary according to different standards.
- Using simple tools, a watertight roof can be made from the roof tiles. Usually the insulating material in the roof tile is bitumen, nowadays mostly rubberized bitumen, to which SBS elastomer is often added. This is then termed polymer-modified rubberized bitumen, the stretching and flexibility of which at low temperatures are better than simple bitumen. Fatigue resistance and adhesion, as well as low-temperature properties also improve. In other words, the durability of the roof improves, The surface layer of the roof tile is highly resistant to mechanical strain and creates the desired appearance for the roof tile. The film and structure described above can also be applied in bitumen-membrane products. In addition, differing from the embodiment examples, there can be several layers in the roof tile or other bitumen products.
