Definitions

  • the present invention relates to a system for insulating and finishing walls, having rectangular panels that fit together through a tongue-and-groove joint.
  • the panels are made up of an insulating foam panel coated with a flat, solid cladding panel with an upper side provided with a finishing layer.
  • the cladding panel and the foam panel each have a first longitudinal and a first end side, and a second longitudinal and a second end side.
  • the first longitudinal side of the cladding panel is provided with a longitudinal groove
  • the first end side is provided with an end groove and the second end side with an end tongue.
  • the longitudinal tongue fits into the longitudinal groove and the end tongue into the end groove to form the tooth-and-groove joint between the panels.
  • the panels of this known system are constructed from a MDF cladding panel with a melamine finishing layer and from a PIR (polyisocyanurate) rigid foam panel which is glued against the underside of the cladding panel.
  • the MDF panel has a groove on two adjacent sides and a tongue on the other adjacent sides, which fits into the groove such that the finishing layers on top of the cladding panels fit against each other.
  • the MDF panel is sawn off straight on the sides of the grooves, such that the inner and outer walls of the grooves protrude sideways the same distance.
  • the sides of the rigid foam panel are provided with a rectangular rebate just under the MDF panel, while below the grooves in the MDF panel, the rebate is provided on the other side of the MDF panel, such that there is a rectangular tongue on the rigid foam panel just below the grooves in the MDF panel.
  • This tongue protrudes beyond the MDF panel and fits into the groove formed by the rebate and the MDF panel. Because the tongue in the foam panel is meant to support the edge of the MDF panel, it must be rectangular and should connect tightly to the MDF panel. In practice, however, this resulted in the problem that the panels are hard to slide into each other.
  • a further disadvantage of the known insulation and finishing panels is that each of them must be attached to a wooden frame by means of three insulation retaining clips, with two screws per clip.
  • the insulation retaining clips are provided with sharp points with which they are to be pressed into the rigid foam panel. This must be done with one hand, while it is necessary to press the rigid foam panel against the wooden frame with the other hand, in order to press the insulation retaining clips into the foam at the correct position. This is not so simple, especially since it requires some force to press the insulation retaining clip with its sharp points into the rigid foam.
  • the clips then need to be screwed on with six screws.
  • Rectangular panels of the type indicated above are also disclosed in DE 20 2007 010293 U1 . These panels contain a rigid foam panel with on top of that a solid cladding panel.
  • the foam panel consists, in particular, of expanded polystyrene, while the cladding panel is formed of, for example, an OSB panel. From this utility model, which can be regarded as the closest prior art, the following features are further known.
  • the tongue-and-groove joint between the rectangular panels is a double tongue-and-groove joint, the first longitudinal side of the foam panel being provided with a further longitudinal groove, the second longitudinal side with a further longitudinal tongue, the first end side with a further end groove and the second end side with a further end tongue, said further longitudinal tongue fitting into said further longitudinal groove, and said further end tongue into said further end groove, to form a further tongue-and-groove joint between the panels.
  • the longitudinal groove in the cladding panel is further formed by an outer longitudinal groove wall, which is provided with said finishing layer, and by an inner longitudinal groove wall, which is fully supported by the foam panel and having a portion which projects beyond the outer longitudinal groove wall.
  • the panels are easier to slide into one another.
  • the panels themselves are floor panels, which are glued either to each other, or to the substrate.
  • An insulation and finishing system with panels made up of a cladding panel and a rigid foam panel which is provided with a tongue-and-groove joint is further also known from practice and is marketed under the name 'Comboprime® Home'.
  • the cladding panels of this system are plasterboard panels, which, in contrast to the panels the present invention relates to, are not provided with a tongue-and-groove joint. These panels are screwed through the bevelled edges of the plasterboard panels against the frame, after which the joints between the panels and these bevelled edges must be finished with a reinforcement tape and with plaster.
  • all this is also cumbersome work, and the finishing of the joints produces a lot of dust and dirt, and is best done by a professional.
  • the invention therefore aims to propose a new insulation and finishing system that no longer requires joint sealing strips between the various panels, no further finishing of the visible side of the panels and also no insulation retaining clips in order to be able to screw the panels to a wall and which further allows the panels to be fastened to the wall in a faster and easier way, in particular to a wooden frame attached thereto.
  • the insulation and finishing system according to the present invention is characterised in that it further includes screws with countersunk heads in order to screw said panels through the protruding portion of the inner longitudinal groove wall of the cladding panel and through the foam panel against said wall.
  • insulation retaining clips are therefore no longer needed to screw down the panels.
  • These can now easily be screwed down directly through the cladding panel and the foam panel by means of a number of screws, the panels being automatically pulled against the wooden frame correctly by the screws and the heads of the screws being fixed against the cladding board.
  • the foam panels are attached to the frame by the screws, but also the cladding panels, which are glued thereto, so that they cannot come loose.
  • the inner longitudinal groove wall into which the screws are screwed is fully supported by the foam panel, the screws can be tightened according to good practice without the inner longitudinal groove wall being deformed or itself broken. To limit the thickness of the flat, solid cladding panel, this inner longitudinal groove wall has only a relatively small thickness.
  • the foam panel is either manufactured from a rigid foam or it comprises a flexible foam panel, i.e., a foam panel having a compressive strength, measured according to EN 826:2013 at a strain of 10 %, of less than 40 kPa.
  • a rigid foam panel is particularly advantageous for providing thermal insulation.
  • Flexible foams can also provide thermal insulation, and in particular also provide for the avoidance of drafts. However, compared to a rigid foam, they offer the advantage that they can provide better acoustic insulation.
  • the foam panel may include both a rigid foam and a flexible foam, in particular, a layer of rigid foam and a layer of flexible foam.
  • said first longitudinal side of the cladding panel is located on the same side of the panel as the first longitudinal side of the foam panel, and said first end side of the cladding panel is located on the same side of the panel as the first end side of the foam panel.
  • said screws are provided to be screwed through the inner longitudinal groove wall at a distance from the free end of the inner longitudinal groove wall that is greater than the depth D 1 of said further longitudinal groove, where, at said distance from the free end of the inner longitudinal groove a longitudinal groove is preferably provided to which the screws can be applied.
  • the screws can be screwed though the panel perpendicularly without extending through the further longitudinal groove of the foam panel, and thus without forming an obstacle to the insertion of the further longitudinal tongue of the foam panel into this further longitudinal groove.
  • said further longitudinal tongue has a portion with parallel side faces which is provided in order to, up to a predetermined depth of said further longitudinal groove, make contact with the side walls thereof, and said longitudinal tongue has a length which is substantially equal to said predetermined depth.
  • said further end tongue also has a portion with parallel lateral faces which is provided in order to, up to a predetermined depth of said further end groove, make contact with the side walls thereof, and said end tongue has a length which is substantially equal to said predetermined depth.
  • the tongues on the cladding panel and the tongues on the foam panel can be simultaneously positioned in their respective grooves, making it easier to slide two panels into each other in the event of certain deformations of the panels.
  • said further longitudinal tongue and said further end tongue have a distal portion from said portion with parallel side faces that narrows in the direction of the free end of the respective tongue.
  • the free end of the tongues on the foam panel can thus easily be inserted into their respective groove, after which these tongues are centred in their groove, and the panel ends up in the correct position where the tongues on the cladding panel are correctly positioned in the respective grooves in this panel. It is thus easy and effortless to slide the panels together.
  • said end groove is also formed in the cladding panel by an outer end groove wall, which is provided with said finishing layer, and by an inner end groove wall, which is fully supported by the foam panel and having a portion which projects beyond the outer end groove wall.
  • the inner end groove wall will project beyond the outer end groove wall over such a distance that the inner end groove wall will have a length that is substantially equal to the depth of said further end groove in the foam panel that is located on the same side of the panel as said end groove.
  • the insertion of the tongue of the foam panel into the groove on the end side of the panel is also simplified because one can here have the tongue on the end side of the cladding panel guided along the inner groove wall of the groove in the end side of the cladding panel.
  • the cladding panel has an underside through which it is attached on an upper side of the foam panel, the underside of the cladding panel having a circumferential edge which substantially coincides with the circumferential edge of the upper side of the foam panel.
  • the upper side of the foam panel is thus completely protected against possible deformations or damage.
  • the invention in general, relates to a system for insulating (thermally and/or acoustically) and finishing walls, in particular rooms, attics or other spaces inside a building.
  • the term 'wall(s)' comprises both side walls and upper walls (ceilings) and possibly even lower walls (for example, when only the lower wall of an attic needs to be insulated instead of the roof itself).
  • the system is usually applied to spaces that are located under the roof.
  • the system consists of rectangular insulation and finishing panels which are to be attached to the walls.
  • vertical laths are usually screwed to the walls at regular distances. If it concerns a ceiling that is formed by the roof structure, the panels can be directly screwed to the roof structure itself.
  • laths can also be applied here, to fill the roof structure in such a way as to obtain a flat surface.
  • the laths are usually made of wood but it is also possible to use metal studs.
  • the panels are each constructed from a thermally and/or acoustically insulating foam panel 1, which at the upper side, seen according to the figures, is covered with a flat, solid cladding panel 2.
  • This solid cladding panel 2 consists of a material in which tongues and grooves can be provided. This can be done by cutting out, for example, by milling.
  • the cladding panel 2 is preferably a wooden panel.
  • the term wooden panel' should be interpreted broadly to comprise all ligneous panels such as fibreboards, three-ply wood or multi-ply boards, OSB (oriented strand board) and HDF (high-density fibreboard) and MDF (medium-density fibreboard) panels, with preference given to MDF panels.
  • the latter consist of dried wood fibres which are connected to each other by means of a resin and which are pressed together to form a panel with a medium-hard density, in particular, up to a density of 500 to 1000 kg/m 3 .
  • the cladding panel 2 has an upper side which is provided with a finishing layer 3. This may consist of a coat of paint or, for example, of a veneer layer, but preferably of a melamine layer.
  • the finishing layer 3 need not form the final finishing of the panels, but may, for example, afterwards, after installation of the panels, itself still be painted in a colour of choice.
  • the cladding panel 2 will preferably have a total thickness d 1 (including the thickness of the finishing layer 3), which is between 5 and 25 mm, and preferably between 6 and 18 mm.
  • the foam panel 1 may be manufactured from various types of rigid foam, for example, from rigid expanded polystyrene (EPS) foam, from extruded polystyrene (XPS) foam, from phenolic foam (PF) or melamine foam, or from polyurethane (PUR) foam, but preference is given to polyisocyanurate (PIR) foam, which has a good thermal insulation rating, and can provide the necessary rigidity at a relatively low density.
  • the hardness of the rigid foam is preferably such that the foam panel 1 has a compressive strength, measured according to EN 826:2013 at a strain of 10 %, of greater than 80 kPa, preferably of greater than 100 kPa.
  • the thickness d of the foam panel 1 should preferably be greater than 2 cm. This thickness D can, for example, go up to 10 cm in order to obtain a better insulation.
  • the foam panel 1 may be made of different types of flexible foam, or a combination of rigid foam and flexible foam.
  • the foam panel 1 may in particular include a hard foam panel in combination with a flexible foam panel.
  • the flexible foam panel 1 may, for example, be cut from large blocks of foam.
  • agglomerated foam will be used.
  • Such a foam may be produced by cutting/shredding pieces of waste foam into foam flakes and by then glueing these foam flakes to each other. This can be done by means of a liquid adhesive that is applied to the foam flakes.
  • use is made of adhesive in the form of fusible fibres which are mixed with the foam flakes and that glue the foam flakes together when the fusible fibres are heated.
  • the fibres are preferably made up of a core having around it a layer of glue (hot-melt adhesive), which melts when heated.
  • glue hot-melt adhesive
  • Such adhesive fibres are described, for example, in FR 3,013,354 and in FR 3,013,344 .
  • the use of adhesive fibres offers the advantage that the foam flakes do not need to be compressed as strongly when being glued together, thus allowing for lower densities.
  • 'Flexible foam' and 'flexible foam panel' in the present description and claims refer to a foam or a panel that is so flexible that the foam panel has a compressive strength, measured according to EN 826:2013 at a strain of 10%, of less than 40 kPa.
  • this compressive strength will be less than 30 kPa, and more preferably, less than 20 kPa.
  • the compressive strength of the flexible foam panel will preferably be greater than 1 kPa, more preferably greater than 2 kPa, and most preferably greater than 3 kPa.
  • the flexible foam panel will furthermore preferably have a density which is greater than 40 kg/m 3 , preferably greater than 50 kg/m 3 , more preferably greater than 60 kg/m 3 and most preferably greater than 70 kg/m 3 .
  • the flexible foam panel will preferably include a polyurethane foam.
  • the foam panel 1 and the cladding panel 2 are rectangular, they each have a first 4, 4' and a second longitudinal side 5, 5', and a first 6, 6' and a second end side 7, 7'.
  • the first longitudinal side 4 of the cladding panel 2 is provided with a longitudinal groove 8, while the second longitudinal side 5 of the cladding panel 2 is provided with a longitudinal tongue 9 that fits into the longitudinal groove 8 of an adjacent panel.

  • the tongues of the cladding panel and of the foam panel are located on the same side of the panel, as are the grooves.
  • the advantage of this is that the tongues of the foam panel do not protrude or only do so minimally under the cladding panel, while the bottom of the cladding panel is fully supported by the upper side of the foam panel.
  • the lower side of the cladding panel 2 preferably has a circumferential edge which substantially coincides with the circumferential edge of the upper side of the foam panel 1.
  • these coinciding circumferential edges are indicated with the reference sign 20.

  • the protruding portion of the innermost longitudinal groove wall 17 is provided in order to be able to directly screw down the panels by means of screws 18 with countersunk heads through the cladding panel 2 and the foam panel 1. So as to apply the screws 18 in the right place on the projecting portion of the inner longitudinal groove wall 17, that is, at a location where the screw 18 would not be screwed through the longitudinal groove 12 in the foam panel 1, and also not against the edge of the finishing layer 3 such that it would be damaged by the head of the screw 18 when screwing it in, this protruding portion of the inner longitudinal groove wall 16 has a longitudinal groove 19 into which the tip of the screw 18 should be positioned.
  • the longitudinal groove 12 in the foam panel 1 that is located below the inner longitudinal groove wall 16, has a depth D 1 which is preferably smaller than the distance from the longitudinal groove 19 to the free end of the inner longitudinal groove wall 17.
