Description

Title of the invention: DOOR OR WINDOW ASSEMBLY HAVING IMPROVED FIRE RESISTANCE technical field

[0001] The present invention relates to a door or window having improved fire resistance. In particular, the invention relates to said door or window having improved fire resistance, in the absence of mechanical fastening means.

[0002] CONTEXT

[0003] Windows or doors, with or without a security feature (e.g. fire resistance), are typically constructed from a wooden frame and a glass panel. For example, the frame comprises vertical and horizontal profiles that are mounted around the panel. The mechanical fastening means ensures that the frame is coupled to the panel. However, the presence of said mechanical means makes the assembly of the door or window difficult and time-consuming. This requires, for example, the use of glazing beads, rubber and silicone. Furthermore, said means requires the frame to be thick, and also increases the weight of said assembly. Due to the heavy weight of such an assembly, and due to the risk of breakage during transport, such an assembly must also be assembled on site, which adds to the cost and complexity, and consumes more time.

[0004] The present invention aims to solve at least some of the problems mentioned above. Summary of the invention

[0005] In a first aspect, the present invention relates to a door or window assembly for resisting fire. Preferred embodiments of the electrical assembly are provided.

[0006] The assembly comprises a plurality of profiles and a panel. Each profile has a groove along its length, in which the groove is configured to receive one side of the panel. The assembly is characterized in that the panel is chemically bonded to the profiles, whereas the panel is not mechanically bonded to the profiles. Embodiments of the present invention have the advantage that the mechanical means for coupling the panel to the profiles is unnecessary and is avoided. Embodiments of the present invention have the advantage that the need for glazing beads, rubber, and / or silicone is eliminated, and consequently, costs are reduced. Embodiments of the present invention have the advantage that the profiles are as thin as possible and also as small in size as possible, since they do not include no mechanical fastening means are required. The embodiments of the present invention have the advantage that the profiles conceal the chemically bonded area and also conceal the locking and opening mechanisms of the assembly, which is aesthetically pleasing. The embodiments of the present invention have the advantage that the assembly is as lightweight as possible, since they do not include any mechanical fastening means. The embodiments of the present invention have the advantage that the assembly is assembled during production and transported in its entirety to the construction site. The embodiments of the present invention have the advantage that special glass installation work is no longer required. The embodiments of the present invention have the advantage that the assembly retains its safety function, e.g., fire safety function.The embodiments of the present invention have the advantage that chemical coupling provides a satisfactory alternative for rigid connection between the panel and the profiles, compared to the traditional mechanical means.

[0007] Said mechanical means is normally metallic. Embodiments of the present invention have the advantage that metallic parts are avoided due to their high thermal conductivity. Embodiments of the present invention also have the advantage that wood and glass have lower thermal conductivities than metal.

[0008] The panel can be chemically bonded to said profiles using an adhesive material. Embodiments of the present invention have the advantage that said adhesive material provides a satisfactory, simpler, cheaper, and lighter alternative to the traditional mechanical means.

[0009] The adhesive material may be present on at least one side of the groove. Embodiments of the present invention have the advantage that satisfactory coupling between the panel and the profiles is achieved using a minimal amount of adhesive.

[0010] The adhesive material may be present along said profiles. Embodiments of the present invention have the advantage that the profiles are very well coupled to the profiles. Embodiments of the present invention have the advantage that an equal tensile force due to the adhesive is applied and distributed on the sides of the panel, to pull the panel and the profiles towards each other.

[0011] The assembly is adapted in such a way that a foaming material can be insertable between at least one of the profiles and an external frame surrounding the assembly, and / or between the external frame and a wall connected thereto, and / or in the groove. Embodiments of the present invention have the advantage that said foaming material provides additional fire resistance, for example in the event of a fire by increasing its size to cover and limit any air passage from one side of the assembly to the other side.

[0012] The panel may be a glass panel. Embodiments of the present invention have the advantage that a fire-resistant panel is provided. Said glass panel preferably does not have cutouts. Embodiments of the present invention have the advantage that a simple assembly that is economically cost-effective is obtained.

[0013] The sides (e.g. four sides of a rectangular panel) of said panel are inserted into said grooves. The thickness of each groove is adapted to that of the panel. Embodiments of the present invention have the advantage that the groove has a depth which allows said groove to keep said panel stable and securely fixed in place inside the profiles, using only a chemical coupling means (e.g. the panel is prevented from tilting). Embodiments of the present invention have the advantage that the adhesive material is preserved from wear, thus increasing the service life of said assembly.

[0014] The profiles may be made of wood, preferably made of Meranti® wood. Embodiments of the present invention have the advantage that said profiles are fire resistant, for example more fire resistant than their equivalents comprising metal parts, e.g. steel and aluminum.

[0015] In a second aspect, the present invention relates to a method of assembling a fire-resistant door or window assembly. A preferred embodiment of the method is provided.

[0016] In a third aspect, the present invention relates to the use of a door or window assembly according to the first aspect of the present invention, and / or a method according to the second aspect of the present invention, for assembling a fire-resistant door or window assembly.

[0023] The present invention relates to a fire-resistant door or window assembly.

[0024] Unless otherwise defined, all terms used in the disclosure of the invention, including technical and scientific terms, have the meaning generally accepted by a person skilled in the art of this invention. Definitions of terms are included for guidance purposes to better understand the teaching of the present invention.

[0025] As used herein, the following terms have the following meanings:

[0026] “A”, “an”, “the” and “the” as used herein denote both the singular and the plural, unless the context clearly indicates otherwise. For example, "a compartment" means one or more compartments.

[0027] “Understand”, “comprising”, and “includes” and “composed of”, as they are used herein, are synonymous with "include", "including", "includes" or "contain", "containing", "contains" and are inclusive or open terms that specify the presence of the following, e.g., a component, and do not exclude or prevent the presence of additional uncited components, features, elements, members, steps known in the art or disclosed herein.

[0028] The citation of numerical ranges by the bounds includes all numbers and fractions subsumed within that range, as well as the bounds cited.

[0029] In a first aspect, the present invention relates to a door or window assembly for resisting fire. The assembly comprises:

[0030] a plurality of profiles, and

[0031] a panel,

[0032] wherein each profile has a groove along said profile, wherein said groove is configured to receive one side of said panel,

[0033] characterized in that

[0034] said panel is chemically coupled to said profiles, wherein said panel is not mechanically coupled to said profiles.

[0035] The inventors noted with astonishment that the fire resistance of the assembly is at least similar to, or even better than, that of the prior art (i.e., comprising a mechanical means). This is due to the fact that a mechanical means is normally made of metal such as steel or other materials, which exhibit conductivity. high thermal. An advantage of the invention is that it avoids the use of such metallic mechanical means. Furthermore, the use of glazing beads, rubber and / or silicone is also avoided, thus avoiding the costs of these. This results in a reduction in the weight of the assembly, which makes it possible, easier, more cost-effective and more practical to assemble said assembly during production, rather than on site.

[0036] In a preferred embodiment, each profile acts as a part or edge of a frame of the assembly, wherein, for example, four profiles (e.g., two vertical profiles and two horizontal profiles) constitute said frame surrounding a rectangular panel (e.g., a regular rectangle having four sides and four 90° angles), for example, one profile per side. The preferred number of profiles is four profiles holding a rectangular panel. However, the invention can also be implemented with three profiles, in which, for example, the panel is triangular, or five profiles, in which, for example, the panel has a pentagonal structure. The angles of the panel structure may be equal, but not necessarily so. The preferred panel structure is a rectangular structure having all four angles equal to 90°. The aim is to adapt the profiles to completely surround and cover the edges of said panel.

[0037] In a preferred embodiment, the profiles can also be chemically bonded to each other so as to surround the panel. For example, each profile has two edges, in which the edges are complementary to the other profiles. For example, the edges may include a 45° inclination, in which every two adjacent profiles complement each other so as to completely surround the panel.

[0038] In a preferred embodiment, once each profile receives one side of the panel, the panel is held in place, after which one of said profiles is fitted with hinges so as to fix said assembly to an external frame and e.g. to use it as a window or door.

[0039] In a preferred embodiment, the panel may be chemically coupled to said profiles using an adhesive material. For example, the adhesive material may comprise trimethoxyvinylsilane. For example, the adhesive material may be Proma bond ®. The thermal resistance of said material is between -40 °C and 100 °C. Said material provides at least 4 hours of fire resistance. Proma bond ® is a bonding agent sealing technique based on the latest generation of hybrid sealants. It is of very high quality, strong and is a single-component product. It is odorless, neutral and does not contain isocyanates. After application, it reacts with moisture to dry and develops into a permanently flexible connection. It is suitable for glass, especially laminated glass. However, many other adhesive materials with fire resistance may be suitable.

[0040] In a preferred embodiment, the adhesive material may be laid down and used to couple said panel to said profiles during production, in which the assembly is then carried in its entirety to the site. Carrying said assembly is easy since very minimal additional weight is added by the profiles and the adhesive material. This also reduces the time taken to assemble the door, and does not compromise the security of the door. The strength of the adhesive, and the amount of adhesive applied between the panel and the profiles, depends on the weight and size of the panel.

[0041] In a preferred embodiment, said adhesive material may be present at least on one side of the groove, preferably on two opposite sides of the groove. For example, the groove may be U-shaped or semi-circular, in which for example the adhesive is deposited on the two parts forming an angle of 90°.

[0042] In a preferred embodiment, the adhesive material may be present along said profiles, for example on each profile. For example, one or two lines of adhesive along said profile, or in a zigzag pattern along said profile. For example, the adhesive may be distributed equally over different parts of the profiles. For example, after connecting the profiles to the panel, the adhesive applies an equal tensile force, e.g., by pulling each profile towards one side of the panel, so that the sides of the panel are not detached from the profiles.

[0043] In a preferred embodiment, the assembly is adapted such that the foaming material is insertable between at least one of the profiles and an external frame surrounding the assembly, and / or between the external frame and a wall connected thereto and / or in the groove.

[0044] In a preferred embodiment, the foaming material may comprise ammonium phosphate or may be a graphite-based material.

[0045] In a preferred embodiment, a space between at least one of the profiles and the outer frame is adapted to receive a first graphite-based foam sealant. In other words, a first graphite-based foam sealant may be present on at least one or all of the profiles, for example, between the profiles and the outer frame. For example, having a width between 5 and 20 mm, preferably about 10 mm, and a thickness between 1 and 5 mm, preferably about 3 mm. A space between the outer frame and the wall is adapted to receive a second graphite-based foam sealant. In other words, a second graphite-based foam sealant may be present between the outer frame and the wall. For example, having a width between 30 and 50 mm, preferably about 40 mm, and a thickness between 1 and 5 mm, preferably about 2 mm.

[0046] In a preferred embodiment, one or both of the first and second graphite-based foaming sealants may be present. These are flexible intumescent sealants. When exposed to fire, the intumescent sealant contained in a thermoplastic carrier expands to at least 9 times its initial thickness. In this case, the gap between any of the profiles and the outer frame, or the outer frame and the wall, would be blocked by said graphite-based sealant, thus resisting fire and smoke. A robust microporous layer is formed during expansion which prevents the passage of any flame, smoke or hot gas. Said material has high flexibility, is resistant to moisture and carbon dioxide, and is easy to cut. Expansion begins at about 180°C, in which a thickness between 9 and 15 times its initial thickness is reached within 30 minutes at 550°C.The weight of said material is between 2 and 5, preferably 3 kg / m3. Such a material is designed for both indoor and outdoor use, and it increases the fire resistance of building elements.

[0047] In a preferred embodiment, the groove is adapted to receive a foaming material (e.g., an inflatable material). For example, a foaming material may be present in the groove, preferably between two opposite sides of the groove (e.g., between two layers of adhesive material). For example, the groove is adapted to receive said material. This material foams or inflates (i.e., increases in size) in the event of a fire, thus providing additional fire safety resistance. For example, it can block smoke (e.g., smoke and hot gases) and reduce heat transfer between two sides of the assembly.

[0048] In a preferred embodiment, the foaming material may also be present in a locking and button closure means for the assembly. This can be advantageous since said means is normally metallic. Said material may cover any other part along which air has a passage, such that in the event of a fire, said material would swell and foam, and said passages would be blocked to, e.g., smoke, fire, and heat transfer. For example, between the outer frame and the assembly, or between the outer frame and the wall.

[0049] In a preferred embodiment, the ammonium phosphate-based foaming material may be Interdens®. Such a material protects and improves the fire resistance of wood and wood-based materials. When exposed to a direct flame or radiant heat, it rapidly and abundantly forms a microporous, thermally insulating, spongy layer that prevents or delays the ignition and heating of a treated surface. It hermetically fills voids caused by distortion and provides an effective barrier against the passage of fire, hot gases, and hot fumes.

[0050] In a preferred embodiment, the Interdens ® may be type 5 or 15 (soft), or type 36 (semi-rigid). In a preferred embodiment, intumescence (e.g., foaming) begins at 180°C. In a preferred embodiment, the Interdens ® forms a foam with or without expansion pressure. In a preferred embodiment, the foam height is between 10 and 15 times the initial thickness. For example, 12 times the initial thickness at 350°C over a period of 20 minutes. The initial thickness is between 0.5 and 5 mm, preferably 0.6 mm, 1 mm, and 2 mm for types 5, 15, and 36, respectively.

[0051] In a preferred embodiment, Interdens ® 5 and 15 are suitable for protecting flat and curved surfaces, improving the fire resistance of structural components, and reducing wood combustion. For example, partitions, the perimeter of circular glass, protection of locks, lock retainers and hinges. Interdens ® 36 is used for sealing the edges of structural components (e.g. between a wooden door leaf and an external door frame).

[0052] In a preferred embodiment, said panel is a glass panel. Said glass panel comprises at least one layer of glass, preferably two or three layers of glass. Since no mechanical means are present, the need for cutouts in said panel is eliminated. This is advantageous since making cutouts is not economically viable.

[0053] In a preferred embodiment, the glass is a glass rated for its fire resistance. For example, a Pyrobel ®, contraflam ® or polflam ® type glass. Said glass may comprise a laminated glass assembled with glass sheets and transparent and fire-resistant intumescent interlayers between the laminated e.g. reinforced glass. Said interlayers transform into a rigid and opaque protective shield against fire, keeping away flames, smoke and gas, and partially or totally limiting the transfer of heat through the glass, and reduces the temperature on the protected surface of the glass, in order to provide protection, e.g. for humans. Said glass is preferably fire-resistant on both sides. An edge sealant may be placed on the edges of the glass to improve the fire resistance.

[0054] In a preferred embodiment, the glass panel is suitable for both indoor and outdoor applications. In a preferred embodiment, the fire rating of the glass panel is between EI30 and EI60. In another embodiment, the fire rating may also be between EI90 and EI120. In a preferred embodiment, the temperature range that the glass can withstand is between -40°C and 50°C. In a preferred embodiment, the energy transmission TE is between 50% and 70%. % through the glass is achieved. In addition, an energy reflection between 5% and 10%, preferably about 7% from the glass, is achieved.

[0055] In a preferred embodiment, the assembly has a fire resistance rating between EU 30 and EU 60, according to European standard EN 1634.

[0056] In a preferred embodiment, the width of the glass panel is between 800 mm and 2,500 mm, preferably between 1,000 mm and 2,000 mm, more preferably about 1,116 mm. The height of the glass panel is between 1,900 and 4,200 mm, preferably between 2,000 mm and 3,000 mm, more preferably about 2,201 mm. The glass panel may be in a landscape or portrait configuration. The total thickness of the glass panel is between 15 and 50 mm, for example depending on the type of glass panel (e.g., 15 mm to 40 mm for a panel with a fire rating of EI30, and 25 mm to 50 mm for a panel with a fire rating of EI60). Most preferably, the thickness is between 16 and 17.3 mm. The glass is fire resistant for at least 10 minutes, preferably at least 20 minutes, most preferably at least 30 minutes. The weight of the glass panel is approximately 30 kg / m2 to 80 kg / m2.In one embodiment, the weight is between 30 and 200 kg, preferably between 100 and 200, more preferably about 150 kg, for example for a glass panel having dimensions of about 1000 x 2000 mm. The total weight of the assembly is mainly the weight of the glass.

[0057] In a preferred embodiment, the profiles may be made of wood. For example, the profiles may be made of Meranti® wood, or any other type of wood that is fire resistant. For example, Meranti® wood is fire resistant and has superior thermal conductivity. The density of the wood is preferably between 400 kg / m3 and 700 kg / m3, preferably between 500 kg / m3 and 600 kg / m3, most preferably about 550 kg / m3.

[0058] In a preferred embodiment, each profile may have a length adapted to the length of one side of the panel (e.g. slightly longer to enclose the panel). Each profile may have a thickness between 15 and 75 mm, preferably between 20 mm and 65 mm, more preferably between 40 and 60 mm. Each profile may have a width between 30 and 100 mm, preferably between 40 mm and 80 mm, more preferably between 50 and 70 mm. The definition of the thickness and width is shown for example in [Fig.4] below.

[0059] In a preferred embodiment, said groove has a thickness between 10 and 70 mm, preferably a thickness between 20 and 60 mm, more preferably a thickness between 25 and 50 mm, most preferably a thickness between 27 and 30 mm. Said groove further has a width between 10 and 40 mm, Preferably, the width should be between 10 and 20 mm, and more preferably between 10 and 15 mm. The panel thickness must be adapted to the groove thickness to prevent movement, e.g., tilting of the panel (i.e., due to the adhesive material). For example, the panel thickness should be less than 30% less than the groove thickness, preferably less than 20%, more preferably less than 10%, and most preferably less than 5%. For example, there should be a gap between the panel and the groove (e.g., on all sides of the panel-groove interaction area), in which this gap should be between 2 and 8 mm, and preferably between 4 and 6 mm. The adhesive should be present in this gap. The definition of the thickness and width is shown, for example, in [Fig. 4] below.These dimensions may depend on the type of glass; therefore, the dimensions are not understood to be limiting for all types of glass.

[0060] In a preferred embodiment, each profile encloses between 1.5% and 3% of the panel's volume, preferably 1.8%. Consequently, the four profiles enclose between 6% and 12% of the panel's volume, preferably 7.2%. This percentage is calculated so that the glass panel is securely fixed by the profiles (e.g., so that the glass is held in place and prevented from tipping), while also ensuring that the profiles are as lightweight as possible. For example, the profiles should be as thin and small as possible to reduce weight and size, but also sufficiently large and rigid to provide protection for the panel's edges, particularly for a glass panel, e.g., from breakage.

[0061] In a preferred embodiment, the door or window assembly may be a hinged door or window assembly, a swinging door or window assembly, or a sliding door or window assembly, or the like. The assembly is preferably hinged by stainless steel hinges which hold the assembly, e.g., to an external frame. The hinges have a length preferably between 80 and 120 mm, and a diameter preferably between 10 and 20 mm. More preferably, the hinges have a length of about 100 mm, and more preferably a diameter of 16 mm. For example, at least two hinges, or at least four hinges may be present.

[0062] In a preferred embodiment, an elastic seal can be placed between the outer frame and the wall, for example, partially or completely around the outer frame. For example, such an elastic seal can have a width between 10 mm and 25 mm and can be made of silicone, e.g., Acryrub® type from Soudai®. Furthermore, a fire-resistant PU foaming material is present between the outer frame and the wall.

[0063] In a preferred embodiment, a rubber layer may be present on the outer frame. For example, between the outer frame and any of the profiles. For example, the weight of the rubber may be between 30 and 40 g / m, preferably about 35 g / m. The surface area of ​​the rubber may be between 25 and 35 mm2, preferably about 27.2 mm2. Together with the rubber layer, or included therein, a graphite-based material (e.g., Flexilodice®) may be present. Such a material acts as an intumescent material, which expands to e.g., 10 times its initial thickness at high temperatures, thereby resisting fire and smoke. For example, the weight of the graphite-based material may be between 20 and 30 g / m, preferably about 23 g / m. The surface area of ​​the graphite-based material may be between 10 and 20 mm2, preferably about 15 mm2.

[0064] In a second aspect, the present invention relates to a method of assembling a fire-resistant door or window assembly, according to the first aspect. The method comprises the steps of:

[0065] providing a panel, preferably a glass panel,

[0066] providing a plurality of profiles, preferably four profiles, preferably wooden profiles

[0067] adapting each profile so that it has a groove along said profile, wherein said groove is configured to receive said panel, and

[0068] chemical coupling of said panel to said profiles,

[0069] characterized in that the method does not include the step of:

[0070] mechanical coupling of said panel to said profiles.

[0071] In a preferred embodiment, the method may further comprise the step of providing an adhesive material in the groove, preferably on two opposite sides of the groove, so as to bond the panel to the profile.

[0072] In a preferred embodiment, the method may further comprise the step of providing a foaming material between at least one of the profiles and an outer frame surrounding the assembly, and / or between the outer frame and a wall connected thereto and / or in the groove.

[0073] In a preferred embodiment, the method may further comprise the step of configuring the groove to be U-shaped, or semi-circular. In a preferred embodiment, the method may further comprise the step of matching the thickness of the groove to the thickness of the glass panel, or vice versa. For example, the thickness of the panel (e.g., glass panel) is less than 10% less than the thickness of the groove, preferably less than 5%, more preferably less than 2%.

[0074] In a third aspect, the present invention relates to the use of a fire-resistant door assembly according to the first aspect of the present invention, and / or the use of a method according to the second aspect of the present invention, for assembling a fire-resistant door or window assembly. This results in the same fire resistance or improved fire resistance, while at the same time avoiding the use of mechanical means to assemble said assembly.

[0075] Other features and advantages of embodiments of the present invention will be described with reference to the figure. It should be noted that the invention is not limited to the specific embodiment shown in the figure.

[0076] [Fig. 1] shows a front view of the window or door assembly (100) for resisting fire. The assembly (100) comprises a plurality of profiles (2, 3, 4), for example four wooden profiles (2, 3, 4). The assembly (100) further comprises a panel (5), for example a rectangular multi-layer glass panel (5). Each profile (2, 3, 4) has a groove (14) along said profile (2, 3, 4). The groove (14) is configured to receive one side of said panel (5). For example, each of the four sides of the panel (5) is inserted into a groove (14) of a profile, such that said four sides of the panel (5) are received and held by said four profiles (2, 3, 4). After this, the panel (5) is chemically coupled to said profiles (2, 3, 4), wherein said panel (5) is not mechanically coupled to said profiles (2, 3, 4).For example, no mechanical means are present to hold the panel (5) in the grooves (14) of the profiles (2, 3, 4). For example, a chemical substance is deposited between each profile and the panel (5) to bond them together. The chemical bond is strong enough to hold the panel (5) in the grooves (14) of the profiles (2, 3, 4), and is also lighter in weight than mechanical (e.g., metallic) equivalents. For example, an adhesive material (6) can be used, such as Proma Bond®.

[0077] A button (15) of the assembly (100) is used, e.g., to open and / or close said assembly (100), in conjunction with a locking means (16). The internal parts of the button (15) and the locking means (16) are concealed within one of the profiles (4). A hinge (13) is used to connect said assembly to an external frame (1), said external frame (1) being connected to a wall (9) (or e.g., a partition, or other).

[0078] The external frame (1) is made of wood, preferably Meranti ® wood, having a density preferably of 550 kg / m3.

[0079] The profiles (2, 3, 4) are made of wood, preferably Meranti® wood having a density preferably of 550 kg / m3. The thickness of the profiles (2, 3, 4) is preferably about 60 mm, for example 58 mm. The width of the profiles (2, 3, 4) is for example greater at the side to which the assembly (100) is articulated than at the other side. For example, about 70 mm.

[0080] Fig. 2 shows a cross-sectional view of the window or door assembly (100) through (A), viewed from above in Fig. 1. The adhesive material (6) is present on two opposite sides of the groove (14). A foaming material (17) is present between the two opposite sides of the groove (14). An elastic seal (12) is placed between the outer frame (1) and the wall (9) (or e.g. partition). In addition, a fire-resistant PU foam material (8) may be present between the outer frame (1) and the wall (9).

[0081] A layer of rubber (7), for example PVC rubber, is present on the outer frame (1), for example between the outer frame (1) and any of the profiles. Together with the rubber layer (7), or included therein, a foamable graphite-based material is present.

[0082] A first graphite-based foaming sealant (10) is present between one or all of the profiles (2, 3, 4), for example between the profiles and the outer frame (1). A second graphite-based foaming sealant (11) is present between the outer frame (1) and the wall (9). These are both flexible intumescent sealants (11).

[0083] [Fig. 3] shows a cross-sectional view of the window or door assembly (100) through (B), looking from the right in [Fig. 1]. The adhesive (6) is present along said profiles (2, 3, 4), on two sides of said groove (14). The panel (5) is then inserted into the groove (14). The groove (14) has dimensions that are adapted to those of the panel (5), wherein the thickness of the panel (3) is slightly less than the thickness of the groove (14), to allow the insertion and bonding of the panel (5) into the groove (14). This makes it easier to hold the panel (5) in place, since it leaves no room for the panel (14) to move (e.g., tilt) within the groove (14), which prevents the adhesive (6) from wearing out, and prolongs the service life of the assembly (100).

[0084] [Fig.4] shows a cross-sectional view of the groove (14) in one of the profiles (2, 3, 4) of the assembly (100). Table 1 below shows the dimensions indicated in [Fig.4] in preferred ranges, for an assembly having a fire resistance rating between EU 30 and EU 60 according to European standard EN 1634.
