Definitions

  • the present invention relates to a method for improving the sound dampening properties of a roof window, which, in the mounted state, penetrates a roof surface, said roof window comprising a pane and at least one frame surrounding the pane.
  • the invention further relates to a covering kit and to a sound dampened roof window.
  • the dampening of the noise caused by the precipitation striking the covering kit members does in fact cause an audible decrease in the sound level on the interior side of the window. Tests have shown decreases of up to 7 dB in comparison with a window fitted with a standard covering kit.
  • the adhesive tape works by dampening the vibrations in the covering kit member caused by the precipitation hitting it.
  • the elastic adhesive both cushions the sound and functions as resilient suspension for the tape, which serves as a barrier for the sound.
  • a realistic alternative to the use of the adhesive tape is the use of a plastic material, which may temporarily be brought into a state where is has adhesive properties. This may for example be achieved by heating. When cooling off, the plastic will stick to the surface of the covering member while regaining its original physical properties. It may thus be said so function as a combined adhesive and tape.
  • the adhesive tape may in principle be applied to all members of the covering kit and cover them entirely on one or both sides. Some surfaces of the covering kit members will, however, be located in relatively protected locations, which precipitation will rarely reach. It may therefore be advantageous to only apply adhesive tape to those sections of the covering kit members, which are parallel to the pane in the mounted state and which are not covered by roofing material. It is, however, to be understood that the application of the adhesive tape does not only dampen the sound caused by the impact of each individual hail or rain drop, but that it also dampens the vibrations caused in the entire covering kit member. The application of adhesive tape to sections of the covering kit member not directly affected by the precipitation may thus also contribute to improving the acoustic image experienced by persons in the room on the interior side of the window.
  • the adhesive tape is preferably applied to an interior surface of the covering kit member(s), preferably during the manufacture of the covering kit member(s). If applying the adhesive tape prior to surface treatment, such as lacquering, it may, however, also be applied on the exterior side. If wishing to improve the sound dampening properties of windows already installed, the application on the exterior side may be the only possibility.
  • Some covering kit members have a relatively deep trough shape, which may make it difficult to apply the adhesive tape. If these members are made by deformation of a sheet material it may therefore be advantageous to apply the adhesive tape prior to the deformation. Some kinds of adhesive tape will be capable of following even large deformations, but in other cases it may be necessary to limit the application to sections not directly affected by the deformation.
  • the adhesive tape used may of course be of a pre-manufactured type, but when working with covering kit members being manufactured continuously from strips of metal, by extrusion or the like it will often be advantageous to apply the adhesive and the tape in two separate steps. This may for example be done by first applying a pressure-sensitive adhesive to the material of the covering kit member and then applying a tape of metal, plastic or the like on top thereof. A rolling mill may be used for this purpose.
  • the cost of the materials used for the adhesive tape will usually be very modest it will normally be preferred to apply it substantially over the entire length of the covering kit member(s). In some cases it may, however, lead to an improved sound dampening if the adhesive tape is applied at discrete sections of the covering kit member(s). This may for example be achieved by applying adhesive tape in the form of sticker-like punched out portions, which may be rectangular or have more complex shapes.
  • the adhesive tape may in principle be any that gives a satisfactory sound dampening.
  • the covering kit members will be subjected to relatively large variations in temperature and humidity due to shifting weather, it will be advantageous if the adhesive tape has substantially the same coefficient of expansion as regards moisture and temperature as the material used for the covering kit member itself. This may easily be achieved by using a tape made from the same material as the covering kit member(s), i.e. usually aluminium.
  • the tape need not be homogeneous, but may have a grid-like structure, where thicker material sections alternate with section of thinner material or holes. Composite materials may also be used.
  • an acrylic adhesive As for the adhesive it is preferred to use an acrylic adhesive as this have proven both reliable and durable, but other adhesives such as butyl may of course also be used.
  • FIG. 1 A roof window 1 mounted in a roof 2 with a covering kit 3 according to the invention is shown in Fig. 1 .
  • the covering kit comprises a top covering 31, a bottom covering 32, side coverings 34, 35, side claddings 36, a bottom cladding 37, a top flashing 38 and a bottom flashing 39.
  • the window is centre-hung and the side coverings therefore comprises an upper member 34 and a lower member 35.
  • a single longer side covering may be used.
  • Fig. 2 shows a perspective view of the lower side covering 35, seen from the interior side.
  • An adhesive tape 40 which is depicted with a grey colour in the figures, has been applied for sound dampening purposes.
  • the adhesive tape has been applied only on the face 351 of the covering member, which is parallel to the window pane in the mounted state (cf. Fig. 1 ), whereas those faces that are perpendicular to the window pane are left uncovered.
  • the zones affected by the deformation are not covered by the adhesive tape.
  • the adhesive tape may be applied prior to deformation without the risk of being torn by the tools or that it may be applied afterwards without having to be taken around corners, the edge 41 of the tape 40 being substantially aligned with the line, where the side covering member begins to bend.
  • the interior width d of the covering member is not affected by the application of adhesive tape on the sides of the covering and it may thus still be fitted over the window side frame member without the need for adaptation of any of them. The standardised sizes of the covering and frame parts may thus be maintained.
  • the tape may be taken along the entire length of the lower side covering member 35, thus also covering the part 353 projecting underneath the upper side covering member 34 in the mounted state as depicted in Fig. 1 , or it may be terminated at the ends 354, 355 of the flat section 351.
  • Holes 356, 357 in the parts of the covering member covered by the adhesive tape are preferably made after the application of the adhesive tape, but it is to be understood that the adhesive tape may also be provided with punched out holes thus allowing it to be applied subsequently.
  • the tape shown in Figs. 2-4 is a continuous tape of constant thickness, which is cheap to manufacture and easy to work with. In special circumstances it may, however, be advantageous to use a tape of a more complex design, e.g. made from expanded metal or having local thickenings.
  • an acrylic adhesive is used.
  • Such adhesives are well tested and have proven capable of maintaining their strength and elasticity during the expected life span of modern roof windows.
  • Other adhesives may of cause also be used.
  • An example of such an adhesive is butyl, which have also proven sufficiently durable. Butyl, however, has to be applied in a thicker layer, which causes problems with most modern type covering kits, where the space beneath them have been minimised to improve the insulating properties of the window. The use of such alternative adhesive might therefore lead to the need for a modification of the shape of one or more members of the covering kit and thus possibly to the need for new tools or methods of manufacture.
  • the adhesive may be applied uniformly or in more complex configurations such as spots, lines or grids.
  • the tape When using an adhesive tape consisting of an aluminium tape of a homogeneous configuration and uniform layer of an acrylic adhesive, the tape should preferably have a thickness of 0,05-0,10 mm and the adhesive layer should have a thickness of 0,03-0,07 mm. Tests have shown, that a particularly good sound dampening of covering kit members made from aluminium sheets with thickness of 0,8 mm is achieved with an aluminium tape of 0,07 mm and an adhesive layer of 0,05 mm.
  • the covering kit members are usually made by roll forming, where a sheet of aluminium passes between a series of rollers, which bends it appropriately.
  • the force that has to be applied by each roller or pair of rollers depends on the thickness of the aluminium, possible surface coatings etc.
  • the adhesive tape may not be capable of withstanding these forces, particularly the shearing forces caused by the rotation of the rollers. It will therefore often be advantageous to apply the adhesive tape only in sections of the covering kit member not affected by the roll forming or to apply it after the deformation of the affected areas.
  • Fig. 3 shows a top covering member 31 for a centre-hung window depicted up-side-down to reveal the adhesive tape 40 applied on the interior side.
  • a relatively narrow strip of adhesive tape has been applied to the face most heavily affected by precipitation, but it is of course also possible to use a wider strip, that may cover the entire interior surface.
  • the strip of adhesive tape not only covers the relatively wide plane section 311 of the covering member but also extends somewhat over the inclining section 312. This bend 313 may make it difficult to apply the adhesive tape and the application is therefore performed prior to the formation of the bend. The same applies to the bends 314, 315 at the end sections of the covering member.
  • Fig. 4 shows a bottom covering member 32 for a centre-hung window, again depicted up-side-down.
  • this covering member is somewhat more complicated, than those described above.
  • This covering member thus has to be subjected to a relatively complex deformation, which worsens the problem of tearing of the adhesive tape 40 described above, even when it is applied only on a flat face 321. In this case it is therefore particularly preferred to apply the adhesive tape after deformation.
  • the deformation process may be split in two, with the application of the adhesive tape interposed.
