INSULATING BOARD SHEET AND ITS USE Field of invention The invention relates to a sheet of insulating boards according to the appended independent claim. The invention also relates to the use of a sheet of insulating boards as a protective covering, in particular to a sheet of insulating boards for use as a protective covering for storing snow. Background of the invention Currently, it is more common to store snow during the summer in thermally insulated snow storage facilities to maintain snow on slalom or cross-country ski slopes. Summer snow storage requires covering the stored snow with sufficient thermal insulation materials suitable for this purpose, so that melting can be prevented as efficiently as possible. A quick and easy way to install and remove thermal insulation for snow storage is to arrange the insulation materials in a sheet of insulating panels folded like an accordion. In this type of insulating panel sheet, the insulation materials, such as individual panels or groups of panels, are typically contained in cases or sleeves with two opposite open ends made of a water-resistant material. The panels or groups of panels fitted inside the cases or sleeves are joined together by hinges, forming an accordion-like folded structure. When the insulating panel sheet is unfolded, the panels or groups of panels held together by the cases or sleeves sit firmly against each other.The successive joints of the insulating board sheet are positioned alternately on the upper and lower surfaces of the boards. By means of these joints, the insulating board sheet can be folded accordion-style into a stack, and conversely, it can be easily unfolded and carried into a snow pile. Water accumulation at the seams between insulating boards, in the folds that open towards the top surface of the insulating board sheet, poses a challenge for accordion-style insulating board sheets. Water collected in these seam areas can flow into the snow pile, causing unwanted melting. While insulating board sheets can be positioned on top of the stored snow in each specific case, they are typically arranged to minimize rainwater ingress from beneath the sheet. To prevent rainwater from flowing under the insulating board sheets, separate seam protection covers can be used, placed over the folded areas of the insulating board sheets. This prevents rainwater from easily passing, for example, under the insulating board sheet and reaching a snow pile.These types of protective covers for separate joints are difficult to install, and yet rainwater can pass under the sheet of insulating boards from some areas of the joints. Object and description of the invention An object of the present invention is to reduce or even eliminate the problems mentioned above in the prior art. An object of the present invention is to provide an accordion-folded sheet of insulating boards having a structure that reduces or prevents rainwater from reaching and accumulating in the folded areas between the sheets of insulating boards of the sheet of insulating boards and thereby also prevents rainwater from entering underneath the sheet of insulating boards. An object of the invention is to provide, in particular, an accordion-folded sheet of insulating boards that is easy to install and does not require the use of separate joint protection covers to protect the joint areas of the insulating board sheet, to prevent rainwater from entering them. To achieve this objective, the sheet of insulating plates, according to the invention, is characterized mainly in what is presented in the characterizing part of the independent claim. The insulating plate sheet, according to the invention, comprises sheets of insulating plates successively placed and joined together on their edge side that is in the transverse direction relative to the longitudinal direction of the insulating plate sheet, alternately at the upper corners and lower corners of the transverse edge sides, so that the uniform insulating plate sheet that is formed comprises several sheets of insulating plates that can be folded into an accordion-shaped folded stack of insulating plate sheets and unfolded again into a uniform insulating plate sheet, and this insulating plate sheet has an upper surface and a lower surface.The upper surface of the insulating plate sheet, according to the invention, comprises a surface layer that is arranged in the longitudinal direction of the insulating plate sheet, alternately joined and separated from the insulating plate sheets, in groups of two successive insulating plate sheets. The insulating board sheet, according to the invention, can be used as a protective cover. According to one embodiment of the invention, the insulating board sheet, according to the invention, is used as a protective cover for the thermal insulation used in snow storage. Specifically for snow storage, the insulating board sheets, according to the invention, can be easily placed on and / or to the sides of an adjacent snow pile and / or successively, and after the snow storage stage, the insulating board sheets, according to the invention, can be folded into a stack due to their accordion-like structure, making them easy to store. The insulating board sheet, according to the invention, can also be used as a protective cover in other applications.In particular, it is inexpensive to use the insulating board sheet in places where a protective covering with thermal insulation properties is needed. The accordion-folded structure of the insulating board sheet, according to the invention, allows for easy use of the insulating board sheet. In the method according to the invention, for covering the object to be protected, the object is covered at least partially with sheets of insulating boards according to the invention. In the method according to the invention, for providing thermal insulation for snow storage, the snow pile formed at the snow storage location is covered with thermal insulation materials, at least some of which are insulating boards, and the sheets of insulating boards according to the invention are used to thermally insulate the snow pile. The accordion-folded insulating sheet, according to the invention, is based on a surface layer arranged longitudinally on the upper surface of the insulating sheet, which typically extends substantially along the entire length and width of the sheet. This surface layer is arranged longitudinally and alternately attached to and separated from the insulating sheets. In the insulating sheet, according to the invention, the surface layer on its upper surface is arranged longitudinally and alternately attached to and separated from the insulating sheets in groups of two successive insulating sheets.In this way, the surface layer bonded to the insulating board sheets bears the load when the sheet is moved. This surface layer forms a uniform coating on the top surface of the sheet when it is unfolded. This prevents rainwater from penetrating the seams between the insulating board sheets. However, the surface layer does not impede the accordion-like structure of the insulating board sheet. The sheet can be folded accordion-style by stacking the sheets and then unfolded again into a uniform sheet. The insulating board sheet, according to the invention, facilitates its use as a protective cover, as it eliminates the need for separate joint covers or other protective coverings to prevent rainwater from penetrating the joints between the insulating board sheets. The insulating board sheet, according to the invention, provides an easy and cost-effective protective cover, particularly for use as a protective cover for storing snow and other objects requiring thermal insulation. Brief description of the drawings The invention will now be described in more detail with reference to the accompanying drawings, in which: Figure 1 shows a sheet of insulating boards according to the state of the art in a cross-section in the longitudinal direction of the sheet of insulating boards, i PQQnn / oznz / R / Yi Figure 2 shows a bonding zone opening towards an upper surface between the insulating board sheets in a sheet of insulating boards according to the state of the art. Figure 3 shows a sheet of insulating plates, according to one embodiment of the invention, in a cross-section in the longitudinal direction of the sheet of insulating plates, wherein the surface layer is arranged in the longitudinal direction of the sheet of insulating plates alternately joined and separated from the sheets of insulating plates, in groups of two successive sheets of insulating plates. Figure 4 shows a sheet of insulating plates according to an embodiment of the invention, unfolded as a uniform sheet of insulating plates as shown in a cross-sectional view, in the longitudinal direction of the sheet of insulating plates. Figure 5 shows an edge structure of insulating plate sheets in the insulating plate sheet, according to an embodiment of the invention, in which structure a surface layer comprises a fold and through holes and / or fixings arranged in the fold. Figure 6 shows a structure of a joining zone between two adjacent sheets of insulating plates, according to one embodiment of the invention, and Figure 7 shows a sheet of insulating plates according to an embodiment of the invention as shown from above, in which the surface layer is bonded to the insulating plate sheets at the edges of the surface layer, in groups of two insulating plate sheets, in the longitudinal direction of the insulating plate sheet. Detailed description of the invention An insulating board sheet, according to the invention, comprises successively placed insulating board sheets joined together along their edge side, which is transverse to the longitudinal direction of the insulating board sheet, alternately at the upper and lower corners of the transverse edge sides, thus forming an accordion-folded insulating board sheet. The longitudinal direction of the insulating board sheet is a direction in which the insulating board sheets are successively hinged together to obtain an accordion-folded sheet structure. The number of insulating board sheets in the insulating board sheet may vary.The insulating board sheet has an upper surface and a lower surface, surfaces that are formed by sheets of insulating board when the insulating board sheet is unfolded into a uniform insulating board sheet. The upper surface of the insulating board sheet, according to the invention, further comprises a surface layer. Typically, the surface layer is arranged substantially over the entire length and width of the insulating board sheet. The surface layer is arranged only on one surface of the insulating board sheet, according to the invention. In the insulating board sheet, according to the invention, the surface layer, arranged in the longitudinal direction of the insulating board sheet, is alternately bonded to and separated from the insulating board sheets in groups of two successive insulating board sheets. In one embodiment of the invention, the surface layer is bonded substantially to the entire upper surface of the insulating board sheet in an individual insulating board sheet.In another embodiment, the surface layer is attached to the insulating board sheets only on the edges of the insulating board sheets, in the longitudinal direction of the insulating board sheet. In one embodiment of the invention, the surface layer is detachably attached to the insulating board sheets. When the surface layer is separated from successive insulating board sheets, the length of the separated surface layer is defined to correspond to the length of the insulating board sheets along the distance in question in the longitudinal direction of the insulating board sheet, so that a separated area of the surface layer is firmly positioned on the surface of these insulating board sheets when the insulating board sheet is unfolded into a uniform sheet.This arrangement of the surface layer allows the accordion-folded structure of the insulating board sheet to function and, at the same time, protects the upward-opening joint areas. In one embodiment of the invention, the surface layer is arranged in the longitudinal direction of the insulating board sheet, alternately joined and separated from the surface of the insulating board sheets in groups of two successive insulating board sheets, such that the surface layer forms a joining zone of an upper corner of the edge sides that are transverse to the longitudinal direction of every second insulating board sheet in the insulating board sheet, and the surface layer is separated from the surface of the insulating board sheets at every second joining zone of the upper corner.In this way, the surface layer can also be uniformly distributed along the entire length of the top surface of the insulating board sheet. When the insulating board sheet is arranged as a uniform sheet, the surface layer forms a uniform layer that adheres firmly to the surface of the insulating board sheet, thereby preventing rainwater channels from forming in the upward-opening joint areas. In a typical embodiment, the first two and last two insulating board sheets along the length of the sheet comprise a surface layer bonded to the insulating board sheets. In one embodiment according to the invention, the insulating board sheet comprises one insulating board, preferably all the sheets of the insulating board sheet are formed by one insulating board. In another embodiment according to the invention, the insulating board sheet comprises two or more insulating boards arranged against each other. The insulating board sheet, according to the invention, may comprise, for example, groups of insulating boards formed by two or more insulating boards arranged adjacently and / or successively. When the insulating board sheet comprises two or more insulating boards, the insulating boards are typically joined together and / or the insulating boards are arranged within separate cases or sleeves / cases, or the like, with open ends.In one embodiment, the accordion-folded structure of the insulating plate sheet is formed by cases / sleeves and the surface layer, according to the invention, is disposed on the upper surface of the cases / sleeves according to the invention. i PQQnn / C7n7 / R / vi In a typical embodiment, an insulating plate forming the sheet of insulating plates, according to the invention, is a rectangular insulating plate comprising short edge sides and, relative to them, substantially perpendicular long edge sides. In a typical embodiment of the invention, the insulating plate sheets are arranged in the longitudinal direction of the insulating plate sheet, such that the sides of the long edges of the insulating plate sheets are transverse with respect to the longitudinal direction of the insulating plate sheet. Typically, the insulating boards in sheets of insulating boards are made of polyurethane or polystyrene. According to one embodiment of the invention, the insulating board sheet comprises an insulating board made of extruded polystyrene (XPS), expanded polystyrene (EPS), polyurethane (polyisocyanurate and rigid polyurethane, PIR / PUR), and / or polyphenol. In another embodiment, the insulating boards in sheets of insulating boards may also comprise a biomaterial such as polylactide (PLA) foam or a similar material.Thus, the insulating board sheet, according to one embodiment of the invention, comprises one or more insulating boards made of extruded polystyrene (XPS), expanded polystyrene (EPS), polyurethane (PIR / PUR), polyphenol, and / or PLA foam. According to an advantageous embodiment of the invention, the insulating board sheet comprises an insulating board made of extruded polystyrene (XPS). XPS material has high strength and does not absorb water, making it a durable and particularly useful material for the insulating board sheet. Furthermore, XPS has good thermal insulation properties, ensuring a long service life for snow, especially for storage purposes. Alternatively, the insulating boards, or parts thereof, may also be other insulating boards suitable for the purpose.The external dimensions of the insulating panels on the insulating board sheets can be specifically chosen for each application, or standard-sized panels can be used. To adequately withstand the climatic conditions at the snow pile's location, the insulating panels must be of sufficient thickness. A surface layer according to one embodiment of the invention is water-resistant. Typically, the surface layer is formed from a water-resistant material. The surface layer, according to one embodiment of the invention, comprises a fabric-like and / or plastic-like material. In an advantageous embodiment of the invention, the surface layer is formed from a material comprising polyvinyl chloride (PVC) or polyethylene (PE). The surface layer may comprise one or more layers of material. In one embodiment of the invention, the surface layer comprises two or more layers of material, wherein at least one layer comprises a reinforcing material, such as fiber reinforcement.In the insulating board sheet according to the invention, the surface layer is arranged only on one side of the insulating board sheet, so the material for the surface layer can be used as a material having higher quality properties, such as, for example, a material with good resistance to ultraviolet radiation (UV, for its acronym i PQQnn / O7n7 / R / vi in English). In one embodiment of the invention, the surface layer is adhered to the surface of the insulating board sheet. In another embodiment, the surface layer is directly adhered to the surface of the insulating board sheet. In yet another embodiment, a separate reinforcing material bonded to both the surface layer and the insulating board sheet is arranged between the surface layer and the insulating board sheet. The reinforcing material is at least partially positioned between the surface layer and the insulating board sheet, typically at least in the edge areas of the insulating board sheet. The reinforcing material may be, for example, a fiber-reinforcing material, such as a fabric-like material.The purpose of the reinforcing material is to strengthen the structure and, where necessary, ensure the surface layer is attached to the surface of the insulating board sheet. Particularly in the edge areas of the insulating board sheets, where most of the forces are directed when the sheet is moved, the reinforcing material strengthens the structure of the insulating board sheet, according to the invention. The reinforcing material may be, for example, bonded to the surface of the insulating board sheet and glued and / or stitched to the surface layer. The surface layer, and any reinforcing material, may also be attached to the insulating board sheet by other suitable means. In one embodiment of the invention, the surface layer, or the surface layer and the reinforcing layer, are detachably attached to the insulating board sheets. In one embodiment of the invention, the underside of the insulating board sheets may be coated. The purpose of the coating is to protect the insulating board material and thereby make the insulating board sheets more durable. In a typical sheet of insulating boards, according to the invention, at least the joining areas of the side edges that are transverse with respect to the longitudinal direction of the sheet of insulating boards and between the layers of the insulating boards, and in which the joining areas do not comprise a bond forming the surface layer, comprise a hinge structure. In one embodiment according to the invention, all the joining areas of the edge sides that are transverse with respect to the longitudinal direction of the sheet of insulating boards, and between the layers of the insulating boards, comprise a hinge structure. The hinge structure may comprise, for example, an elastic mass and / or a reinforcing material such as, for example, fiber reinforcement, or the hinge structure may be formed in another manner suitable for the purpose.In all joint areas comprising a separate hinge structure, the surface layer does not need to be bonded to the surface of the insulating board sheets. The surface layer on the top surface of the insulating board sheet bears the stress and load directed to the sheet itself, thus significantly reducing the stress on other joint areas between the insulating board sheets, which can therefore be formed more easily. To form a joint, only a suitable compound, glue, and / or adhesive tape can be used, for example, but durability can be increased by also using a reinforcing material, fiber reinforcement, or something similar in the joint area.In one embodiment of the invention, the joining zones of the insulating board sheets are formed in a detachable manner by means of fastening. The joints between the insulating board sheets are typically arranged along the entire length of the insulating board sheets in the longitudinal direction of the joining zone. In one embodiment of the invention, the articulated fixing of the sheets of the insulating plates can be implemented so that at least a portion of the sheets of successive insulating plates are arranged in cases or sleeves with two opposite open ends, formed from a material similar to a water-resistant fabric, so that the cases or sleeves of the sheets of successive insulating plates are connected to each other at one of their edges by a suitable joint.Thus, the sheets of insulating boards arranged in the cases or sleeves are joined together at their opposite edges in an articulated manner, by means of the joints between the cases and the sleeves. Furthermore, a separate surface layer is arranged on the upper surface of the insulating board sheet. This surface layer, arranged according to the invention, is alternately attached to and detached from the insulating board sheets in the longitudinal direction of the sheet. In one embodiment of the invention, the surface layer is attached to the cases and sleeves of the insulating board sheets only at the lateral edges of the insulating board sheets, in the longitudinal direction of the sheet.In another embodiment according to the invention, the surface layer is adhered to the surface of the cases / sleeves of the insulating board sheets, preferably over the entire surface. When the insulating board sheet, according to the invention, comprises a separate surface layer, the cases and sleeves of the insulating board sheets can be made of a less expensive material, and only the surface layer can be made of a more durable material, for example, a UV-resistant material. In an insulating board sheet according to one embodiment of the invention, the insulating board sheets are arranged in a detachable manner so that they can be easily replaced if a sheet is damaged. When the insulating board sheets are detachably attached to the insulating board sheet structure, the insulating board sheet structure can also be easily disassembled when necessary. In a sheet of insulating boards, according to one embodiment of the invention, a fold is formed in the surface layer at the transverse end edges relative to the longitudinal direction of the sheet, and / or at the lateral edges of the insulating board sheets along the longitudinal direction of the insulating board sheets. A fold means that the surface layer is at least double-folded over a certain distance, so that a separate fold can be formed from the surface of the insulating board sheets at the lateral edge of the insulating board sheets and / or at the end edges along the longitudinal direction of the sheet.In one embodiment according to the invention, through-holes are arranged in the fold over the surface layer to allow the fastening means to be attached to the fold of the surface layer and thereby join adjacent and / or successive sheets of insulating boards i PQQnn / C7n7 / R / vi together. In one embodiment according to the invention, the fold comprises, for example, one or more annular through-holes such as eyelets or the like. In one embodiment according to the invention, the through-holes, such as eyelets, may be arranged on the edge of the surface layer that extends beyond the sheet of the insulating boards. This edge may be formed from a single layer of the surface layer, or the edge of the surface layer may be at least double-folded.In one embodiment of the invention, these through-holes can be fitted with separate fastening means, such as cords, zippers, or the like, allowing for quick and easy fastening of adjacent and / or successive sheets of insulating boards to each other, as tightly as possible, without leaving a large gap between them. According to another embodiment of the invention, other fastening means can also be provided to allow the sheets of adjacent and / or successive insulating boards to be fastened together at the edge(s) of the surface layer and / or at the folds formed in the surface layer. Fastening can be achieved by tying or, for example, by using a zipper positioned at the edge(s) of the surface layer and / or at the folds formed in the surface layer.In this way, the sheets of insulating plates, according to the invention, can be formed in large areas for a protective cover, and there is no need to provide separate protective covers for the joining areas between the separate sheets of insulating plates to ensure sufficient firmness. Typically, the insulating sheet, according to the invention, further comprises a pulling member for moving the insulating sheet to and from its location of use. The pulling member may be, for example, a rope, cable, traction sling, or something similar. Typically, the insulating board sheet, according to the invention, can be used as a protective cover. In particular, the insulating board sheet according to the invention is a protective cover used in the thermal insulation of snow storage facilities. The method for providing thermal insulation for snow storage comprises covering the snow pile formed at the snow storage site with thermal insulation materials. In the method according to the invention, sheets of insulating boards according to the invention, which can be arranged adjacently and / or successively on the snow pile, are used for the thermal insulation of the snow pile. At least some of the thermal insulation used to cover the snow piles consists of sheets of insulating boards, according to the invention, which are joined together in an accordion-like fashion and placed adjacently and / or successively on top of or to the sides of a snow pile when insulating the snow storage. After the snow storage stage, when the stored snow is used, they are folded again in an accordion-like fashion for storage and reuse.The surface layer of the insulating board sheets, according to the invention, forms a uniform covering on the upper surface of the insulating board sheet when the sheet is unfolded into an elongated sheet, thus effectively preventing water from penetrating the snow pile. The insulating board sheets are arranged adjacently and / or successively on the snow pile, and are joined together by means of pins and / or fasteners located at the edge of the sheets. The insulating board sheets can also be used to protect other objects. Detailed description of the drawings Figure 1 shows a sheet of insulating boards (1), according to the prior art, in a cross-sectional view in the longitudinal direction of the sheet of insulating boards. The sheet of insulating boards (1) comprises successively placing sheets of insulating boards (2a, 2b, 3a, 3b, 4a, 4b) joined together along their edge side, which is transverse with respect to the longitudinal direction (P) of the sheet of insulating boards, alternately at the upper and lower corners of the transverse edge sides, so that the uniform sheet of insulating boards that is formed and comprises several sheets of insulating boards can be folded into an accordion-shaped stack and unfolded as a uniform sheet of insulating boards, and this sheet of insulating boards has an upper surface and a lower surface.Typically, in a prior art insulating board sheet, the insulating board sheets are arranged within casings. The successively arranged insulating board sheets are joined together in a hinged manner, with the casings of the insulating board sheets being joined alternately at their opposite edges by means of a suitable joint to form an accordion-like folded structure of the insulating board sheet. Typically, the insulating board sheets are housed within the casings, so that in each insulating board sheet, the material protecting the insulating material surrounds the insulating board sheets. Figure 2 shows a challenge in a sheet of insulating boards in the prior art, specifically in the joint zone between two successive sheets of insulating boards (2a, 2b), where the joint zone opens onto the upper surface of the insulating board sheet. As illustrated by an arrow in Figure 2, the joint zone can form a channel in the insulating board sheet, allowing water to enter from the surface. In this case, water can flow through this channel in the joint zone into a snow pile covered by the insulating board sheet, thus causing unwanted melting of the snow beneath the sheet. Figure 3 shows a sheet of insulating plates (1), according to one embodiment of the invention, in a cross-sectional view in the longitudinal direction of the insulating plate sheet. The insulating plate sheet (1), according to the invention, comprises successive sheets of insulating plates (2a, 2b, 3a, 3b, 4a, 4b) joined together at their edge sides, which are arranged transversely with respect to the longitudinal direction (P) of the insulating plate sheet, alternately at the upper and lower corners of the edge sides in the transverse direction, such that the uniformly formed insulating plate sheet comprising several sheets of insulating plates can be folded into a stack of accordion-folded insulating plate sheets and unfolded into a uniform insulating plate sheet, and this insulating plate sheet has an upper surface and a lower surface.The upper surface of the insulating board sheet (1), according to the invention, comprises a surface layer (5). The insulating board sheet (1) has an upper surface and a lower surface. The lower surface faces the object being covered when the insulating board sheet is unfolded into a uniform sheet, and the upper surface forms the outward-facing surface of the insulating board sheet. In the longitudinal direction (P) of the insulating board sheet, the surface layer (5) is alternately attached to and separated from the insulating board layers.In Figure 3, the surface layer (5) is bonded to the insulating board sheets in two successive insulating board sheets, and the surface layer (5) forms a bonding zone at the upper corner of the edge sides that is transverse to the longitudinal direction (P) of the insulating board sheet between these successive insulating board sheets, such as the bonding zone of insulating board sheets (2a and 2b), and (4a and 4b), in Figure 3. In Figure 3, the surface layer (5) is bonded to the insulating board sheets (2a, 2b) and separated from the insulating board sheets (3a, 3b) in the longitudinal direction of the insulating board sheet, and again, bonded to the following insulating board sheets (4a, 4b).The attachment of the surface layer (5) in the longitudinal direction of the insulating board sheet (1), according to an advantageous embodiment of the invention, continues in the same manner in groups of two successive insulating board sheets along the entire length of the sheet. As illustrated in Figure 3, the surface layer (5) is peeled off from two successive insulating board sheets between points (A) and (B). The width of a single insulating board sheet in the longitudinal direction of the sheet is (X), and therefore the length of the peeled surface layer in the longitudinal direction of the sheet between points (A) and (B) is (2X). The lower surface (7) of the insulating board sheets may be coated with a suitable coating. In the insulating sheet, according to an embodiment of the invention shown in Figure 3, at least the joints between the insulating sheet layers (2b) and (3a), the insulating sheet layers (3a) and (3b), and the insulating sheet layers (3b) and (4a) are formed in a manner suitable for the purpose by, for example, a separate elastic mass and / or fiber reinforcement between the upper or lower edges of the edge sides of the insulating sheet layers, to form a hinge structure. The bonding zone beneath the surface layer (5) may also have a separate joint, which is formed in a manner suitable for the purpose created. Figure 4 illustrates a sheet of insulating plates, according to an embodiment of the invention, deployed in a uniform sheet of insulating plates, in which the surface layer (5) forms a uniform surface fitted over the upper surface of the insulating plate sheets, in the longitudinal direction (P) of the entire sheet of insulating plates. Figure 5 shows a fold (8), according to one embodiment of the invention, on the edge of the insulating board sheets (2a). The fold (8) is formed in the surface layer (5) at the transverse end edges relative to the longitudinal direction of the insulating board sheet, and / or at the lateral edges of the insulating board sheets, in the longitudinal direction (P) of the insulating board sheet. The fold (8) is formed by arranging the surface layer (5) at least double-folded along a certain distance. Typically, the fold (8) comprises one or more through holes (9a, 9b), such as eyelets or other fastening means. Figure 5 also shows that a separate reinforcing material (6) is arranged between the surface layer (5) and the insulating board sheet (2a), bonded to both the surface layer (5) and the insulating board sheet (2a). This reinforcing material is positioned between the surface layer (5) and the insulating board sheet (2a), at least in the edge areas of the insulating board sheets (2a). This allows the surface layer to be firmly attached to the insulating board sheet, making the structure durable. Figure 6 schematically shows a structure in which two sheets of insulating boards (11, 12), according to the invention, are placed adjacent to each other with their ends firmly pressed together. The sheets of insulating boards (11, 12) are firmly joined together by means of folds (8) and fastening means (10) connected to them at their ends. In the embodiment shown in Figure 6, the folds (8) partially overlap when the sheets of insulating boards (11, 12) are placed against each other. A separate fastening means (10), such as a zipper structure, can be attached to these folds, allowing the sheets of insulating boards to be fastened together easily and securely. Figure 7 shows a sheet of insulating boards, according to an embodiment of the invention as illustrated above, in which the surface layer (5) of the insulating board sheets is bonded, at the edges of the surface layer on the insulating board sheets, in groups of two insulating board sheets, in the longitudinal direction (P) along the entire length of the insulating board sheet. In the figure, the surface layer is bonded to the edges of the insulating board sheets (2a, 2b, 4a, 4b), continuing in this manner in groups of two insulating board sheets along the entire length of the insulating board sheet. In this embodiment, the insulating board sheets (2a, 2b, 3a, 3b, 4a, 4b) can be arranged inside separate cases / sleeves and form an accordion-folded insulating board sheet.The surface layer (5) is arranged on the upper surface of the insulating board sheet and is attached to the edges of the insulating board sheets by means of fastening (13) in groups of two insulating board sheets.
