Abstract
Description
- The present invention relates to an insulating panel intended to be clamped between two mutually opposing surfaces, and a method of clamping the insulating panel between two mutually opposing surfaces.
- The insulating panel comprises a thermally insulating plate which has a compressive strength, measured to EN 826:2013, on deformation of 10 %, of at least 50 kPa, wherein said thermally insulating plate has a first and a second side, which sides lie mutually opposite each other and each have a height, and wherein the insulating panel furthermore comprises at least one elastically compressible strip which is intended to be compressed in order to clamp said thermally insulating plate by said sides between said surfaces, which strip also has a compressive strength, measured to EN 826:2013, on deformation of 10 %, of at most 40 kPa.
- Such an insulating panel is used for example in building works in order to ensure adequate thermal insulation thereof. In these building works, a framework, such as boards or beams arranged at a distance from each other, is provided with a number of spaces in which insulating panels must be placed, wherein the framework thus serves as surfaces between which the panels must be placed. However, the spaces may have a multiplicity of sizes and forms in which sometimes obstacles such as electrical lines or waste pipes are arranged. The fitting of insulating panels in spaces of different sizes requires either the production of a specific insulating panel for each different space, or the use of an insulating panel which is sufficiently flexible to fit the different sizes.
-
EP 1 360 382 B1 - A disadvantage of such an insulating panel is that the thermally insulating plate is foldable, whereby the panel, if a tensile force is exerted thereon, can come out of the space. So to ensure that the panels remain in the framework, these must be covered on their front side with a covering, for example a gypsum plasterboard or wooden laths.
- Another disadvantage of such an insulating panel is that it cannot be clamped in the space without folding the plate. More specifically, if one tries to push the insulating panel into the space without the plate being folded, the compressible strips will press against the edges of the space, for example the beams. Because the compressible strips are also flexible, these are then bent so that they protrude partially on the front side of the plate. In this way, less compressible material is compressed between the thermally insulating plate and the solid surfaces, whereby the thermally insulating plate is secured less firmly. The compressible material furthermore spreads out on the front side of the insulating panel, which is less aesthetically pleasing than a flat finish. The protruding material must then be cut away, which is also time-consuming. To avoid these disadvantages, the known insulating panel is therefore intended to be fitted between the mutually opposing surfaces in the folded state. By then pressing the plate flat, a force is exerted on the compressible strips, whereby the strips are compressed and the thermally insulating plate is clamped elastically between the two surfaces.
- Another disadvantage of such an insulating panel is that it is not possible to adapt the panel to a space which is smaller than the size of the thermally insulating plate alone in its flat state. Namely it is not possible to cut away part of the plate, since then the flexible strips will also be cut away, whereby the panel can no longer be clamped into the space.
- It is an object of the present invention to provide an insulating panel which need not be folded before being clamped between two surfaces, and which offers the possibility of preventing the compressible strip or strips from spreading over the front side of the insulating panel when the insulating panel is pressed between the two surfaces.
- This object is achieved by forming said strip by an elastically compressible, flexible plate which is attached to the rear side of said thermally insulating plate and which, in unbent state, protrudes at least over the first side, wherein the protruding part of said flexible plate is intended, when the insulating panel is clamped between said surfaces, to be bent and elastically compressed against said first side.
- Because the flexible plate is attached on the rear side of the thermally insulating plate and protrudes on the first side thereof, when the insulating panel is placed between the surfaces, the flexible plate first comes into contact with the frame, for example the beams or boards which form the surfaces. When the panel is pressed further between the surfaces, the protruding part is bent against the first side, insofar as this has not already been bent against the first side. Then, in particular on the rear side of the thermally insulating plate, the space between the first side of the thermally insulating plate and the adjacent surface is completely filled with the compressible material. After bending of the protruding part, this part is also elastically compressed between the first side and the corresponding surface, so that the insulating panel is clamped between the surfaces, without the thermally insulating panel having to be folded. The insulating panel according to the invention is thus more rigid, lowering the risk that it will become detached from the surfaces again.
- Furthermore, this insulating panel has the advantage that it can be used even if the distance between said surfaces is smaller than the width of the plate. Namely it is possible to cut away part of the thermally insulating plate without removing the flexible plate.
- In an embodiment of the present invention, the insulating panel is provided with a further, elastically compressible strip which is intended to be compressed in order to clamp said thermally insulating plate by said sides between said surfaces, which further strip has a compressive strength, measured to EN 826:2013, on deformation of 10 %, of at most 40 kPa, wherein said further strip is formed by said flexible plate which, in unbent state, furthermore protrudes over the second side, wherein the further protruding part of said flexible plate is intended, when the insulating panel is clamped between said surfaces, to be bent and elastically compressed also against said second side.
- In an alternative embodiment of the present invention, the insulating panel is provided with a further, elastically compressible strip which is intended to be compressed in order to clamp said thermally insulating plate by said sides between said surfaces, which further strip has a compressive strength, measured to EN 826:2013, on deformation of 10 %, of at most 40 kPa, wherein said further strip is formed by a further, elastically compressible, flexible plate which is attached to the rear side of said thermally insulating plate and which, in unbent state, also protrudes over the second side, wherein the further protruding part of said further flexible plate is intended, when the insulating panel is clamped between said surfaces, to be bent and elastically compressed also against said second side.
- In both these embodiments, a protruding part is provided on both sides of the thermally insulating plate, whereby the insulating panel can be clamped against the surfaces at both edges. In addition, in the alternative embodiment, less material is required for clamping the insulating panel between the surfaces, since the entire rear side is not covered.
- In a preferred embodiment of the present invention, said flexible plate is made of an acoustically insulating material, wherein said flexible plate, in unbent state, has a weighted sound reduction index, measured according to EN ISO 717-1:2013, of at least 6 dB, preferably at least 10 dB, and further preferably at least 12 dB.
- In this embodiment, the insulating panel provides both thermal and acoustic insulation, whereby it is not necessary to provide a separate acoustic insulation.
- In a further preferred embodiment of the present invention, said protruding part on said first side protrudes over a distance which is most equal to the height of the first side, preferably over a distance which is at most equal to 90 % of the height of the first side, and more preferably over a distance which is at most equal to 80 % of the height of the first side.
- This has the advantage that the bent and compressed protrusion does not protrude over the front of the thermally insulating plate when clamped between the surfaces.
- In yet a further preferred embodiment of the present invention, said flexible plate has a rear side which is formed by a cladding, preferably this cladding is substantially not stretchable in the direction in which said flexible plate protrudes, and more preferably the cladding is airtight and or water-repellent.
- This has the advantage that the insulating panel is easier to handle. Because of the presence of the cladding, the flexible plate is also easier to cut to size if the insulating panel is too wide. A further advantage is that the cladding is preferably provided to reduce the friction between the flexible plate and the surfaces between which the panel must be clamped, whereby the insulating panel can be pressed more easily between the two surfaces, even if the compressible strip or strips must be compressed substantially.
- In yet a further preferred embodiment of the present invention, the rear side of said thermally insulating plate is provided with a cladding layer on which said flexible plate is attached, which cladding layer is preferably a water-repellent layer, an air-permeable layer and/or a fire-resistant layer, or a combination thereof.
- This has the advantage that such cladding layers need no longer be applied separately, which naturally reduces the total installation time required.
- The invention also relates to a method for clamping an insulating panel as described above between two mutually opposing surfaces, wherein said thermally insulating plate is pushed between the two surfaces, wherein said protruding part is bent against the first side and elastically compressed between the first side and said surface.
- During performance of this method, there is also no need to fold the insulating panel before clamping it between the surfaces.
- In a preferred embodiment of the method according to the invention, before said thermally insulating plate is pushed between said surfaces, at least said thermally insulating plate is cut to size.
- In this way, the insulating panel can also be used between two surfaces, the distance between which is smaller than the size of the thermally insulating plate.
- The invention will be described in more detail below with reference to the following description and the attached drawings.

The drawings shown here are merely diagrammatic representations and not limitative. In the drawings, the dimensions of certain components may be shown exaggeratedly, which means that the parts concerned are not depicted to scale, purely for illustrative purposes. The dimensions and relative dimensions do not necessarily correspond to the actual practical embodiments of the invention.
- The invention relates in general to an insulating panel for the (thermal and/or acoustic) insulation of walls. A typical area of application is for example the insulation of walls inside a building, e.g. the walls of rooms, attics or other spaces inside a building. The term "wall" comprises both side walls and top walls (ceilings), bottom walls (floors, in particular if for example only the floor of an attic must be insulated instead of the roof itself), also partition walls (infill walls). The insulating panels are normally used in the roof, but may in particular also be used for insulating the walls of a wooden frame building. Both the roof and the walls comprise a framework of parallel boards or beams, between which normally at least one thermally insulating panel is fitted. The structure of parallel beams is also used for floor insulation. Then typically rock wool is placed between these beams for thermal insulation.
- The invention may however also be used for thermal and/or acoustic insulation in industrial applications, e.g. in walls of casings or housings for insulating generator sets (motor-driven generators) or HVAC systems (heating, ventilation and air conditioning) or generators. Another typical application area is the transport sector, for example in the insulation of cold walls of refrigerated transport, or for example the insulation of engine compartments of trucks or goods vehicles.

Figure 1 illustrates a front view of part of a wall orroof 1 with beams orboards 2, between which insulatingpanels 3 according to the invention are clamped. -
Figures 2 and3 illustrate how the insulatingpanels 3 are mounted in order to insulate aroof 1, respectively along lines II-II and III-III shown infigure 1 . Theroof 1 is formed by theroof tiles 18 which rest ontile battens 19 mounted on top of the supportingboards 2. It is also possible that a watertight film or watertight sheet material is fitted between the tile battens 19 and theboards 2, but this is not shown in the figures. -
Figure 4 illustrates the fixing of the insulatingpanels 3 in an outer wall of a wooden frame building. The outer wall comprises a framework ofupright beams 2, between which the insulatingpanels 3 are clamped. On the outside of thebeams 2, preferablywooden panels 24 are fitted, for example plywood panels. On the inside of thebeams 2,wooden panels 23 may also be mounted and may for example be finished further with gypsum plaster boards (not shown). On the outside of thewall 1, anouter facade 21 is provided with anair gap 22 between thewall 1 and theouter facade 21. - As illustrated in
figures 5A to 5J , the insulatingpanels 3 are constructed from a thermally insulatingplate 4, on therear side 5 of which an elastically compressible,flexible plate 6 is at least partially attached. Thisflexible plate 6 has, at least on one of thesides plate 4, a protrudingpart figures 7A to 7D , is intended to clamp the insulatingpanel 3 between twosurfaces - The thermally insulating
plate 4 must be sufficiently hard for the insulatingpanel 3 to be sufficiently stiff, and for example not sag if it becomes wet when mounted in the roof. Specifically, the thermally insulatingplate 4 must be sufficiently hard to give it a compressive strength, measured according to EN 826:2013, with deformation of 10 %, of more than 50 kPa, preferably more than 80 kPa, more preferably more than 100 kPa, and most preferably more than 120kPa. - The thickness d (see
figure 5A ) of the thermally insulatingplate 4 is preferably between 2 cm and 24 cm, more preferably between 6 cm and 12 cm, and for example is around 8 cm. The thickness d may thus be selected as a function of the available space to be insulated and the desired thermal insulation value. The length and width of the thermally insulatingplate 4 may vary, and it preferably has a standard length of for example 120 cm and a width or a number of widths which lie for example between 40 and 55 cm. Preferably, the thermally insulatingplate 4 has a rectangular form. - In the different embodiments, the thermally insulating
plate 4 may be made of various foam and/or fibre materials. The foam materials are for example expanded polystyrene foam (EPS), extruded polystyrene foam (XPS), phenol foam (PF), melamine foam or polyurethane foam (PUR), but preferably polyisocyanurate foam (PIR) which has a good thermal insulation value and can achieve the necessary hardness with a relatively low density. The foam material may furthermore comprise foamed glass. The fibre materials are for example based on rock wool. In addition, the thermally insulatingplate 4 may also be made of other thermally insulating materials, for example aerogel or other insulating nanoporous materials. The thermally insulating plate may also consist of a VIP panel (vacuum insulated panel). - In one embodiment, the thermally insulating
plate 4 has a lambda value, measured according to the method described in ASTM C-518-15, which is less than 0.1 W/m*K, preferably less than 0.06 W/m*K, and more preferably less than 0.04 W/m*K. Such values allow adequate thermal insulation to be provided depending on requirements. - The
flexible plate 6 should be sufficiently flexible and elastically compressible for theinsulation panel 3 to be clamped between thesurfaces flexible plate 4 should still offer sufficient strength to clamp the insulatingpanel 3 between thesurfaces flexible plate 6 preferably has a pressure load, at 40 % compression (CLD) measured according to ASTM D-1056-14, of at least 0.5 kPa, preferably at least 2 kPa, more preferably at least 4 kPa and most preferably at least 5 kPa. - Specifically, the
flexible plate 6 has a compressive strength, measured according to EN 826:2013, with a deformation of 10 %, which is less than 30 kPa, preferably less than 20 kPa, and more preferably less than 15 kPa, which allows theflexible plate 6 to be compressed easily. - Preferably, the
flexible plate 6 is substantially not stretchable, or has a tensile strength, measured according to ISO 1798:2008, with an extension of 5 %, which is greater than 100 kPa, and preferably greater than 200 kPa. Such a tensile strength means that the insulating panel can easily be pressed between the boards or bars 2, wherein even if the surface of the boards or bars 2 is rough, the protruding ends of theflexible plate 6 are drawn between the boards or beams 2. - In various embodiments, the
flexible plate 6 may be made of various supple materials, for example a supple foam material or a combination of hard foam materials and supple foam materials. These supple foam materials are for example PUR (polyurethane) foam, and in particular an agglomerated PUR foam. Such a foam may be produced by cutting or crushing pieces of waste foam into foam flakes, and gluing these foam flakes together. This can be achieved using a liquid glue which is applied to the foam flakes. Preferably, however, glue in the form of fusible fibres is used, which fibres are mixed with the foam flakes and glue the foam flakes together when heated. The fibres are preferably bicomponent fibres, i.e. fibres consisting of two components with different melting temperatures. Typically, these are so-called concentric casing/core bicomponent melt fibres. These consist of a core of a polymer with a high melting point, surrounded by a casing of a polymer with a lower melting point. When the fibre/foam flake mixture is heated, the casing melts, whereby the foam flakes are bonded together. The use of glue fibres offers the advantage that the foam flakes need be compressed less when glued together, which therefore allows lower densities. - In one embodiment, the
flexible plate 6, in undeformed state, has a density which is greater than 20 kg/m3, preferably greater than 30 kg/m3, and more preferably greater than 40 kg/m3. - In a preferred embodiment, the
flexible plate 6 is acoustically insulating, so that the insulatingpanel 3 provides both thermal and acoustic insulation. For this, in unbent state, theflexible plate 6 has a weighted sound reduction index, measured according to EN ISO 717-1:2013, of at least 6 dB, preferably at least 10 dB, and further preferably at least 12 dB. - The thickness D (see
figure 5A ) of theflexible plate 6 is between 1 cm and 10 cm, and preferably is around 4 cm. The thickness D can thus be determined on the basis of the available space, which is also dependent on the application, as illustrated infigures 2 and4 , and also on the basis of the desired acoustic insulation. -

The difference between the two is that the rectangular protrudingpart 9 is already bent and attached to theside 7. This fixing may take place in various ways, such as by gluing, taping or by mechanical fixing. -
Figure 5G illustrates an alternative embodiment of an insulatingpanel 3. Thepanel 3 has a rectangular protrudingpart 9 which is already bent and attached to theside 7, and a triangular protrudingpart 10, with therear side 5 completely covered. The thermally insulatingplate 4 also has an obliquely orientedside 8 with a height H. Due to the oblique orientation of theside 8, its height H is greater than the thickness d of the thermally insulatingplate 4. -
Figure 5H illustrates an alternative embodiment of an insulatingpanel 3 which is similar to the embodiment shown infigure 5B . The difference is that the rear side of theflexible plate 6 is formed by acladding 13. The advantage of thiscladding 13 is that theflexible plate 6 can be cut to size and hence processed more easily. Thecladding 13 can also be applied on both sides of the flexible plate. - Preferably, the
cladding 13 is substantially not stretchable in the direction in which theflexible plate 6 protrudes, whereby during application of the insulating panel, the protrudingparts flexible plate 6 are also drawn completely between the mutually opposingsurfaces sides plate 4, even if thesurfaces cladding 13 is airtight and/or water-repellent, so that in the case that the insulatingpanel 3 is used for insulating a roof (seefigure 2 ), theflexible plate 6 does not absorb condensate. -
Figure 5I illustrates an alternative embodiment of an insulatingpanel 3 which is similar to the embodiment shown infigure 5E . The difference between the two is that acladding layer 14 is provided on the uncovered part of therear side 5. -
Figure 5J illustrates an alternative embodiment of an insulatingpanel 3 which is similar to the embodiment shown infigure 5A . The difference between the two is that acladding layer 14 is provided, which forms therear side 5 of the thermally insulatingplate 4. Thiscladding layer 14 is preferably a water-repellent layer, an air-permeable layer, or a fire-resistant layer. Several layers may also be used. This has the advantage that a singleinsulating panel 3 combines various functions, whereby it is not necessary to apply the different layers successively. -
Figure 6A to 6C illustrate a further alternative embodiment of the insulatingpanel 3, wherein acladding layer 25 is attached to the front side of the thermally insulatingplate 4. This cladding layer, like thecladding layer 14 infigure 5J , may also be a water-repellent, air-permeable or fire-retardant layer, or offer a combination of these properties. Preferably, thecladding layer 25 consists of the same material as theflexible plate 6. - In the embodiment according to
figures 6A-6B , thecladding layer 25 protrudes over bothsides layer 4. Thecladding layer 25 here, in particular, like theflexible plate 6, is made of an elastically compressible material so that thecladding layer 25 can also be compressed between thesurfaces flexible plate 6 on the rear side of thepanel 3 protrudes over a distance which is at most equal to the height of theside plate 4, so that the protruding parts of theflexible plate 6 on the rear side of thecladding layer 25 can be pressed against thesides plate 4. - The embodiment according to
figures 6C-6D differs from that according tofigures 6A-6B in that thecladding layer 25 only extends up to thesides plate 4. Theflexible plate 6 however protrudes also over thesides plate 4 and the height of the side of thecladding layer 25, so that theflexible plate 6, after positioning of the insulatingpanel 3 between the twosurfaces panel 3 formed by theflexible plate 6. - The embodiments according to
figures 6A and 6C have the advantage that the thermally insulating panel is better protected, which for example is desirable if this thermally insulating plate consists of a VIP panel. Also, better airtightness is ensured. The provision of alayer 25 also allows, for example, cabling to be integrated therein. Furthermore, anextra cladding layer 26 may be applied againstlayer 25, and protrude beyondlayer 25 so that it can be attached to thelayer 15 of the adjacent panel, for example by means of an adhesive strip or tape. This simplifies the installation for finishing the insulated walls.Layer 26 may e.g. be a damp-proof layer.Layer 26 may also be a visual finishing layer consisting e.g. of Gyproc, OSB, MDF or plywood. Preferably, in this embodiment, the thickness d of the thermally insulating panel and the thickness D oflayer 6 and the thickness oflayer 26 are selected such that the cavity between thesurfaces figures 6B and 6D . - The
flexible plate 6 may be attached to the thermally insulatingplate 4 in various ways, including gluing, taping or mechanical fixing to each other. Also, theseplates plates plates - As illustrated in
figure 1 , several insulating panels may be placed against each other in order thus to insulate the entire space betweenlongitudinal beams 2. It is clear that each insulatingpanel 3 has, as well as twolong sides short sides short side 15 of onepanel 3 is placed against theshort side 16 of a followingpanel 3. In one embodiment, a tongue-and-groove system (as shown infigure 3 ) may be used so that the connection between thepanels 3 is adequately sealed. However, this is not necessary because theflexible plate 6 may also protrude at itssides adjacent panels 3. -
Figure 7A to 7D show various phases in positioning an insulating panel, as shown infigure 5A , between twosurfaces boards 2.Figure 7A shows that the insulatingpanel 3 as a whole is wider than the distance L between the twosurfaces plate 4 is less than the distance L, so that the thermally insulatingplate 4 fits between thebeams 2. Also, the sum of the width B of the thermally insulatingplate 4 and the thickness D of eachprotrusion parts insulating panel 3 between thebeams 2. When the insulatingpanel 3 is pushed further between theboards 2, the protrudingparts flexible plate 6 are bent against thesides figure 7C . At the same time, the protrudingparts Figure 7D shows the insulatingpanel 3 which has been pressed completely into the cavity between theboards 2, wherein the protrudingparts surfaces sides panel 3 is clamped between theboards 2. Because the height of theboards 2 is greater than the total thickness of the insulatingpanels 3, the bent protruding parts of theflexible plate 6 must be moved along the mutually opposingsurfaces boards 2. Here it is advantageous that the friction between the protruding parts of theflexible plate 4 and theboards 2 is reduced by providing a cladding on the rear side of theflexible plate 6. Furthermore, it is advantageous that the elongation of theflexible plate 6 is limited, so that the protruding parts stretch only minimally and thus are drawn between theboards 2. -
Figure 7D also illustrates that there are twoair zones 17, i.e. a part which is not filled, which is the direct result of the manner in which the insulatingpanel 3 is clamped between thebeams 2. However, by providing theflexible plate 6 on therear side 5, theseair zones 17 are not located between thesurfaces sides plate 4, but theair zones 17 are located at the height of the compressibleflexible plate 6. In other words, the space between thesurfaces sides plate 4 is almost completely filled by the protrudingparts panel 3 is clamped more firmly. Because the flexible plate consists of an elastically compressible material, any unevenness in the surface against which the insulating panel is pressed is levelled out without damaging the thermally insulating plate. - Also, it is clear that no fold line is necessary in the thermally insulating
plate 4, nor does this plate have to be foldable in order to place thepanel 3 between the boards orbeams 2 and clamp it firmly. - To prevent the protruding
parts panel 3, the protrudingparts sides figures 5F and 5G ) of thecorresponding side parts side layer 4, but this need not always be the case, in particular if the thermally insulating plate has sloping sides, as illustrated infigure 5G . In addition, it is clear that the two protrudingparts - It is also possible to cut the insulating
panel 3 so that the dimensions, and in particular the width of the panel, are adapted to the distance L between theboards 2. This cutting typically takes place in two phases. In the first phase, the thermally insulatingplate 4 is cut to size, in particular so that this has a width which is smaller than the distance L, such that the insulating panel with the bent protruding parts of the compressible plate can be clamped firmly between theboards 2. In the second phase, theflexible plate 6 is then cut to size. This typically takes place by cutting away part of theprotruding part panel 3 must be cut to size, an embodiment in which acladding 13 forms the rear side of the flexible plate 6 (as shown infigure 5H ) is advantageous, because this simplifies the cutting. - Although certain aspects of the present invention are described in relation to specific embodiments, it is clear that these aspects may also be implemented in other forms.
