    "System for insulating and finishing walls"
    The present invention relates to a system for insulating and finishing walls, which system comprises rectangular plates which fit together via a tongue and groove connection. The plates are made up of an insulating foam plate covered with a flat, solid covering plate that has a top layer provided with a finishing layer. The cladding plate and the foam plate each have a first longitudinal and a first end face and a second longitudinal and a second end face. The first longitudinal side of the cladding plate is provided with a longitudinal groove, the second longitudinal side with a longitudinal tooth, the first end face with a head groove and the second end face with a head tooth. The longitudinal tooth fits into the longitudinal groove and the head tooth into the head groove to form the tongue and groove connection between the plates.
    Such an insulation and finishing system has already been marketed by the applicant. The plates of this known system are constructed from an MDF coating plate with a melamine finishing layer and from a PIR (polyisocyanurate) rigid foam plate that is glued to the underside of the coating plate. The MDF plate has a groove on two adjacent sides and on the other adjacent sides a tongue which fits into the groove such that the finishing layers on top of the cladding plates abut each other. The MDF plate is cut straight on the sides of the grooves such that the inner and outer walls of the grooves protrude equally sideways.
    Below the teeth in the MDF plate the sides of the rigid foam plate are provided with a rectangular stair rebate just below the MDF plate, while under the grooves in the MDF plate the stair rebate on the other side of the MDF plate is provided such that just below the grooves in the MDF plate have a rectangular tooth on the rigid foam plate. This tooth projects beyond the MDF plate and fits into the groove formed by the stair slot and the MDF plate. Because the tooth in the foam plate must support the edge of the MDF plate, it must be rectangular and should fit snugly against the MDF plate. In practice, however, this posed the problem that the plates are difficult to slide together. In order to be able to insert the rectangular tooth into the rectangular groove, it was then milled off to fit into the groove with the necessary clearance. However, an airtight seal was then no longer obtained in this way. In order to nevertheless realize the required airtight connection between the plates, a self-adhesive, compressible joint tape had to be provided between the adjacent plates in the system that was already being marketed. However, the application of such a joint tape is cumbersome and also increases the costs of the system.
    A further drawback of the known insulation and finishing plates is that they must each be fixed to a wooden frame by means of three insulation clips, this with two screws per clip. The insulation clamps have sharp points with which they must be pressed into the rigid foam board. This must be done with one hand, whereby the hard foam board must be pressed against the wooden frame with the other hand in order to be able to press the insulation clamp into the correct position in the foam. This is not all that simple, since it requires some force to press the insulation clamp with its sharp points into the rigid foam. Then these clamps must then be tightened with six screws.
    The use of these insulating clamps with associated screws and the necessity of applying jointing tapes (sealing strips) between the different plates makes installing the plates time-consuming and not so simple and also increases the cost price of the insulation and finishing system.
    From DE 20 2007 010293 U1, rectangular plates of the type indicated above are also known. These plates contain a rigid foam plate with a solid covering plate on top. The foam plate in particular consists of expanded polystyrene while the covering plate is formed by, for example, an OSB plate. Furthermore, the following features are known from this utility model, which can be considered as the closest prior art. The tongue-and-groove connection between the rectangular plates is a double tongue-and-groove connection, wherein the first longitudinal side of the foam plate is provided with a further longitudinal groove, the second longitudinal side with a further longitudinal tongue, the first end face of a further head groove and the second head side of a further head tooth, and wherein said further longitudinal tooth fits into said further longitudinal groove and said further head tooth into said further head groove to form a further tongue and groove connection between the plates. The longitudinal groove in the cladding plate 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 plate and which has a portion protruding beyond the outer longitudinal groove wall.
    By providing a tongue and groove connection in the foam plate, the plates are easier to slide into each other. The plates themselves are floor plates that are glued together or with the substrate. A system for simply mounting these plates against a wooden frame, which is mounted against a side wall or an upper wall, is therefore not described.
    An insulation and finishing system with plates made up of a cladding plate and a rigid foam plate with a tongue and groove connection is also known from practice and is marketed under the name Comboprime® Home. The covering plates of this system are plasterboard plates which, unlike the plates to which the invention relates, are not provided with a tongue and groove connection. These plates are screwed through the beveled sides of the drywall against the frame, after which the seams between the plates and these beveled sides must be finished with a reinforcement tape and with plaster. All this, however, is also a cumbersome job, where finishing the seams produces a lot of dust and dirt and is best carried out by a skilled person.
    The known systems described above are all intended for obtaining thermal insulation and make use of rigid foam boards. A disadvantage of such plates is that they only offer limited acoustic insulation.
    The invention therefore has for its object to propose a new insulation and finishing system which provides better acoustic insulation and which moreover no longer requires joints between the various plates, no further finishing of the visible side of the plates and also no insulation clamps around the to be able to screw plates against a wall and which further allows to screw the plates against the wall in a quicker and simpler way, in particular against a wooden frame attached thereto.
    For this purpose, the insulation and finishing system according to the present invention is characterized in that said foam plate comprises a flexible foam plate, ie a foam plate having a compressive strength, measured according to EN 826: 2013 at a deformation of 10% of less than 40 kPa, and that the system further includes countersunk head screws to screw said plates through the protruding portion of the inner longitudinal groove wall of the cladding plate and through the foam plate against said wall.
    Because flexible foam sheets are used, the acoustic insulation of the system is improved compared to a system in which only hard foam sheets are used. Flexible foams can also provide thermal insulation, and in particular avoid drafts. However, the acoustic insulation that they can provide is generally more important than the thermal insulation. Optionally, the foam plate can contain both a hard foam and a flexible foam, in particular a layer of hard foam and a layer of flexible foam.
    In the system according to the invention, insulation clamps are no longer required for screwing the plates. After all, these can now simply be screwed directly through the cover plate and the foam plate by means of a number of screws, the plates being automatically correctly tightened by the screws against the wooden frame and the heads of the screws getting stuck against the cover plate. Not only the foam plates are fixed against the frame by the screws, but also the cover plates that are glued to them, so that they cannot come loose. Because the inner longitudinal groove wall in which the screws are fitted is fully supported by the foam plate, the screws can be tightened according to good practice without this inner longitudinal groove wall being deformed or broken itself. After all, in order to limit the thickness of the flat, solid cladding plate, this inner longitudinal groove wall has only a relatively small thickness.
    In a preferred embodiment of the system according to the invention, the flexible foam is an agglomerated foam.
    This embodiment offers the advantage that the foam can be made from recycled foam pieces, for example from pieces of waste produced during the cutting of foam blocks or from recycled foam from, for example, discarded mattresses.
    The flexible foam plate preferably has a compressive strength, measured according to EN 826: 2013, with a deformation of 10% of less than 30 kPa, preferably of less than 20 kPa and more preferably of less than 10 kPa. However, the compressive strength of the flexible foam sheet measured according to EN 826: 2013 at a deformation of 10% is preferably greater than 1 kPa, more preferably greater than 2 kPa and most preferably greater than 3 kPa.
    In a preferred embodiment of the system according to the invention, the flexible foam plate has a density that is greater than 40 kg / m3, preferably greater than 50 kg / m3, more preferably greater than 60 kg / m3 and most preferably greater than 70 kg / m3 .
    The flexible foam preferably contains a polyurethane foam.
    In a preferred embodiment of the system according to the invention, said first longitudinal side of the cladding plate is located on the same side of the plate as the first longitudinal side of the foam plate and said first longitudinal side of the cladding plate is located on the same side of the plate as the first end face of the foam plate. Preferably, said screws are provided to be screwed at a distance from the free end of the inner longitudinal groove wall through this inner longitudinal groove wall which is greater than the depth D of said further longitudinal groove, wherein at said distance from the free end of the inner longitudinal groove wall is preferably provided with a longitudinal groove into which the screws are to be fitted.
    In this embodiment, the screws can be screwed perpendicularly through the plate without extending through the further longitudinal groove of the foam plate and thus without impeding the insertion of the further longitudinal tooth of the foam plate into this further longitudinal groove.
    In a further preferred embodiment of the system according to the invention, said further longitudinal tooth has a part with parallel side faces which is provided to make contact with the side walls thereof to a predetermined depth of said further longitudinal groove and said longitudinal tooth has a length which is substantially is equal to this predetermined depth. Furthermore, said further end tooth also has a portion with parallel side surfaces which is provided to make contact with the side walls thereof up to a predetermined depth of said further end groove and said end tooth has a length which is substantially equal to this predetermined depth.
    In this way, the teeth on the cladding plate and the teeth on the foam plate can be positioned simultaneously in their respective grooves, making it easier to slide two plates together if certain deformations of the plates were to occur.
    Preferably, said further longitudinal tooth and said further head tooth from said portion with parallel side faces have a distal portion that narrows toward the free end of the respective tooth.
    The free end of the teeth on the foam plate can thus be easily inserted into their respective groove, after which these teeth are centered in their groove and the plate comes to be in the correct position in which the teeth on the cladding plate are correctly inserted into the respective grooves in this plate. be positioned. Sliding the plates together is thus smooth and effortless.
    In a further preferred embodiment of the system according to the invention, said end groove in the cladding plate is also formed 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 plate and which is a part shows that protrudes beyond the outer end groove wall. Preferably, the inner end groove wall projects beyond the outer end groove wall such that the inner end groove wall has a length that is substantially equal to the depth of said further end groove in the foam plate located on the same side of the plate as said headline groove.
    In this embodiment, the insertion of the tongue of the foam plate into the groove on the end face of the plate is also simplified in that the tooth on the end face of the cladding plate is hereby along the inner groove wall of the groove in the end face of the cladding plate. can be guided.
    In yet another preferred embodiment of the system according to the invention, the cladding plate has a bottom side with which it is adhered to an upper side of the foam plate, the underside of the cladding plate having a peripheral edge which substantially coincides with the peripheral edge of the upper side of the foam plate.
    The upper side of the foam plate is thus fully protected against possible deformations or damage.
    Further advantages and details of the invention will be apparent from the following description of a preferred embodiment of an insulation and finishing system according to the invention. However, this description is only given as an example and is not intended to limit the scope of protection as defined by the claims. The reference numerals given in the description relate to the accompanying drawings in which:
    Figure 1 shows a top view on one of the plates of an insulation and finishing system according to the invention, wherein only the groove in the cladding plate is indicated in dotted line;
    Figure 2, on a larger scale, represents a cross-section along line II-II through the plate of Figure 1;
    Figure 3, on a larger scale, represents a longitudinal section along the line III-III through the plate of Figure 1;
    Figure 4 shows the same cross-section as Figure 2 but at the location of the connection between two plates; and
    Figure 5 shows the same longitudinal section as Figure 2, but this at the location of the connection between two plates.
    The invention generally relates to a system for insulating (in particular acoustically) and finishing walls, in particular rooms, attics or other spaces within a building. The term walls includes 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 plates that must be mounted against the walls. To simplify the fixing of the plates against the walls, vertical slats are usually screwed against the walls at regular distances for this purpose. If it is a ceiling that is formed by the roof construction, the plates can be screwed directly onto the roof construction itself. However, it is also possible here, however, to use slats to fill out the roof construction such that a flat surface is obtained. The slats are usually wooden slats, but it is also possible to use metal studs.
    The plates are each constructed from an acoustically insulating foam plate 1 which, at the top, as seen in the figures, is covered with a flat, solid cladding plate 2. This solid cladding plate 2 consists of a material in which teeth and grooves can be provided. This can be done by cutting, for example by milling. The cladding plate 2 is preferably a wooden plate. The term wooden plate must be interpreted broadly as including all wood-like plates such as fiber plates, plywood or plywood plates, OSB (Oriented Strand Board) plates and HDF (High-Density Fiberboard) and MDF (Medium-Density Fiberboard) plates, with preference being given given to MDF plates. The latter consist of dried wood fibers which are connected to each other by means of a resin and which are compressed into a plate with a medium-hard density, in particular to a density of 500 to 1000 kg / m3
    The cladding plate 2 has a top side which is provided with a finishing layer 3. This can consist of a paint layer or, for example, a veneer layer, but preferably it consists of a melamine layer. The finishing layer 3 does not necessarily have to form the final finish of the plates, but can, for example, be painted afterwards, after the plates have been placed, themselves in a color of choice. The cladding plate 2 preferably has a total thickness di (including the thickness of the finishing layer 3) comprised between 5 and 25 mm, and preferably between 6 and 18 mm.
    For obtaining an acoustic insulation, the foam plate 1 is made of a flexible foam. The foam plate 1 can be made from different types of flexible foam, or optionally from a combination of rigid foam and flexible foam. The flexible foam plate 1 can, for example, be cut from large blocks of foam. However, an agglomerated foam is preferably used. Such a foam can be produced by cutting / grinding pieces of waste foam into foam flakes and then gluing these foam flakes together. This can be done by means of a liquid glue that is applied to the foam flakes. Preferably, however, use is made of glue in the form of fusible fibers which are mixed under the foam flakes and which heat the foam flakes together by heating them. The fibers are preferably constructed from a core with an adhesive layer (hot melt glue) that melts when heated. Such glue fibers are described, for example, in FR 3 013 354 and in FR 3 013 344. The use of glue fibers offers the advantage that the foam flakes need to be compressed less strongly when gluing together, thus enabling lower densities.
    In the present description and claims, flexible foam and flexible foam plate are understood to mean a foam or a plate that is so flexible that the foam plate has a compressive strength at 10% distortion, measured according to EN 826: 2013 of less than 40 kPa. This compressive strength is preferably less than 30 kPa and more preferably less than 20 kPa. However, the compressive strength at 10% distortion of the flexible foam plate is preferably greater than 1 kPa, more preferably greater than 2 kPa and most preferably greater than 3 kPa. The flexible foam sheet further preferably has a density that is greater than 40 kg / m3, preferably greater than 50 kg / m3, more preferably greater than 60 kg / m3 and most preferably greater than 70 kg / m3. The flexible foam plate preferably contains a polyurethane foam.
    The foam plate 1 can also contain a combination of a flexible foam plate and a rigid foam plate. The rigid foam board can be made from different types of rigid foam, for example from hard expanded polystyrene (EPS) foam, from extruded polystyrene (XPS) foam, from phenolic foam (PF), from melamine foam or from polyurethane (PUR) foam, but preference is given to polyisocyanurate (PIR) foam that has a good thermal insulation value and that can provide the necessary hardness with a relatively low density. The hardness of the rigid foam is preferably such that the foam plate 1 has a compressive strength, measured according to EN 826: 2013 at a deformation of 10%, of more than 80 kPa, preferably of more than 100 kPa.
    The thickness d2 of the foam plate 1 is preferably larger than 2 cm. This thickness d2 can, for example, go up to 10 cm in order to obtain better insulation.
    Because the foam plate 1 and the cladding plate 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 face 7, 7".
    The first longitudinal side 4 of the cladding plate 2 is provided with a longitudinal groove 8, while the second longitudinal side 5 of the cladding plate 2 is provided with a longitudinal tooth 9 which fits into the longitudinal groove 8 of an adjacent plate. The first end face 6 of the cladding plate 2 is provided with a end groove 10 while the second end face 7 of the cladding plate 2 is provided with a end tooth 11 which fits into the end groove 10 of an adjacent plate.
    The first longitudinal side 4 "of the foam plate 1 is provided with a longitudinal groove 12, while the second longitudinal side 5" of the foam plate 1 is provided with a longitudinal tooth 13 which fits into the longitudinal groove 12 of an adjacent plate. The first end face 6 'of the foam plate 1 is provided with a end groove 14 while the second end face 7' of the foam plate 1 is provided with a end tooth 15 which fits into the end groove 14 of an adjacent plate.
    The tongue and groove connection between both the cladding panels 2 and the foam panels 1 of the matching insulation and finishing panels ensures effective sealing and thus avoids cold bridges, without leaving draft strips or joints in the gaps between the foam panels. 1 must be applied.
    In the embodiment shown in the figures, the first longitudinal side 4 of the cladding plate 2 and the first longitudinal side 4 'of the foam plate 1 are located on the same side of the plate, and furthermore the first end face 6 of the cladding plate 2 and the first end face 6 'of the foam plate 1 located on the same side of the plate. This means that the teeth of the cladding plate and of the foam plate are located on the same sides of the plate and also the grooves. The advantage of this is that the teeth of the foam plate do not protrude, or only to a minimum, under the cover plate, while the underside of the cover plate is fully supported by the top side of the foam plate. After all, preferably, the underside of the cladding plate 2 has a peripheral edge which substantially coincides with the peripheral edge of the upper side of the foam plate 1. In figures 2 and 3 these coincident peripheral edges are indicated by the reference numeral 20.
    The longitudinal groove 8 in the cladding plate 2 is formed by an outer longitudinal groove wall 16, which is provided on the outside with the finishing layer 3, and by an inner longitudinal groove wall 17 which is fully supported by the foam plate 1. The outer longitudinal groove wall 17 is provided to connect, as shown in Figure 4, to the cladding plate 2 of an adjacent plate. The inner longitudinal groove wall 17 has a length L1 that is greater than the length L2 of the outer longitudinal groove wall 16 such that the inner longitudinal groove wall 17 protrudes a portion beyond the outer longitudinal groove wall 16. The difference between the two lengths L1 and L2 is preferably at least 15 mm, more preferably at least 20 mm, such that the inner longitudinal groove wall 17 protrudes beyond the outer longitudinal groove wall 16 over a distance equal to these length differences.
    The protruding part of the inner longitudinal groove wall 17 is provided to enable the plates to be screwed directly through the covering plate 2 and the foam plate 1 by means of screws 18 with countersunk heads. In order for the screws 18 to be fitted in the right place on the protruding part of the inner longitudinal groove wall 17, ie at a place where the screw 18 would not be screwed through the longitudinal groove 12 in the foam plate 1 and also not against the edge of the finishing layer 3 as a result of which it would be damaged by the head of the screw 18 during screwing in, this protruding part of the inner longitudinal groove wall 16 has a longitudinal groove 19 in which the screw 18 must be positioned with its point. The longitudinal groove 12 in the foam plate 1, which 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. This allows the screws 18 be screwed perpendicularly into the plate without blocking the longitudinal groove 12 in the foam plate 1.
    Figure 4 shows the connection between two plates along the longitudinal sides thereof. In this figure it is clearly seen that, because the longitudinal groove 12 is in the protruding part of the inner longitudinal groove wall 17, the protruding part of the inner longitudinal groove wall 17 and the screws 18 arranged therein are hidden from view when an adjacent plate is inserted with the longitudinal tooth 9 of the cladding plate 2 into the longitudinal groove 12 of the adjacent cladding plate 2.
    The longitudinal tooth 13 of the underlying foam plate 1 has in the figures a part 21 with parallel side faces and furthermore a distal part 22 which narrows in the direction of the free end of the tooth 13. The part 21 with parallel side faces is provided to make a predetermined depth D2 of the longitudinal groove 12 in the foam plate 1 contact with the side walls thereof such that no air can flow between the adjoining foam plates 1, despite the fact that a gap remains open between these foam plates so that the cladding plates 2 always remain perfectly can be attached one after the other. The longitudinal tooth 9 in the cladding plate 2 has a length L3 which is substantially equal to the depth D2 over which the longitudinal tooth 13 makes contact with the walls of the longitudinal groove 12 such that the teeth 9, 13 of the cladding plate and of the foam plate are simple can be slid into their grooves 8, 12 simultaneously. Due to the narrowing distal portion 22 of the longitudinal tooth 13 in the foam plate 1, when two adjacent plates slide into one another, an automatic centering of the two plates relative to each other is obtained, so that the longitudinal teeth can simply be pushed into the longitudinal grooves.
    As can be seen in Figures 3 and 5, the head groove 10 in the cladding plate 2 is formed by an outer head groove wall 23, which is provided on the outside with the finishing layer 3, and by an inner head groove wall 24 which completely passes through the foam plate 1. is supported. The outer end groove wall 23 is provided for connecting, as shown in Figure 5, to the cladding plate 2 of an adjacent plate. The inner end groove wall 24 has a length L4 that is greater than the length L5 of the outer end groove wall 23 such that the inner end groove wall 24 protrudes beyond the outer end groove wall 23 by a portion. The inner end groove wall 24 preferably extends beyond the outer end groove wall 23 such that the length L4 of the inner end groove wall 24 is substantially equal to the depth D3 of the end groove 14 in the foam plate 1. As can be seen in Fig. 3, the end tooth 15 of the foam plate 1 is located almost completely underneath the end tooth 11 of the lining plate 1 on the other side of the plate such that it does not protrude and therefore cannot be damaged in the package. In other words, the covering plate and the foam plate therefore have virtually the same width as a result. The additional overlap between the end tooth 11 of the cladding plate and the inner end groove wall 23 further provides an additional draft barrier and further provides an additional guiding surface when sliding the plates together along their end faces.
    The front tooth 15 of the underlying foam plate 1 has in the figures a portion 25 with parallel side surfaces and furthermore a distal portion 26 that narrows in the direction of the free end of the tooth 15. The portion 25 with parallel side surfaces is provided to make a predetermined depth D4 of the head groove 14 in the foam plate 1 contact with the side walls thereof such that no air can flow between the adjoining foam plates 1 notwithstanding that a gap remains open between these foam plates so that the cladding plates 2 always remain perfectly can be attached one after the other. The end tooth 11 in the cladding plate 2 has a length L6 which is substantially equal to the length L3 of the longitudinal tooth 9 and also to the depth D4 over which the end tooth 15 of the foam plate 1 makes contact with the walls of the end groove 14 such that the teeth 11, 15 of the cladding plate and of the foam plate can simply be slid into their grooves 10, 14 simultaneously. Due to the narrowing distal portion 26 of the head tooth 15 in the foam plate 1, when two adjacent plates are pushed together, an automatic centering of the two plates relative to each other is obtained, as a result of which the end teeth can simply be pushed into the end grooves.
