Description

[0001] Modular thermal insulation device for sealing windows, doors or similar building elements installed in wall or building openings

[0002] Technical area

[0003] The invention relates to a modular thermal insulation device for sealing and insulating windows, doors, or similar structural elements installed in wall or building openings. The thermal insulation device provides additional insulation around the windows and doors of a building, particularly during the cold season.

[0004] State of the art

[0005] It is well known that buildings lose a lot of heat, especially around window and door openings, during the cold season, especially in winter, because the thermal insulation of doors and windows is generally worse than that of the masonry. This heat loss results in significantly more energy being required to heat the rooms. This heat loss in buildings represents a major problem not only due to rising heating costs, but also from an ecological perspective. Heat loss is particularly high in older windows, especially those with single or double glazing or windows with wooden frames, as these neither meet today's thermal insulation standards nor are energy-efficient.

[0006] Another problem is that windows are subject to natural wear and tear, which means that older windows are naturally less airtight. In addition to age, the lifespan of windows is also determined by the materials and construction of the window. Wooden window frames weather and warp over time, while aluminum and plastic windows can shift over the years due to gravity. Another common reason for leaky windows is porous seals on the window frames. In addition, cracks and gaps between the window and the masonry lead to heat loss in the window area. Leaks in the window area often result in drafts, which people find very unpleasant. Insulating or thermal films or cold protection films for windows are already well known and are applied or glued directly to the interior surface of the window pane.The cold protection film applied to the window surface reflects the heat radiation and prevents it from escaping to the outside. Consequently, the heat stays in the room longer. While the cold protection film reduces energy loss at the window pane, it does not cover the window frame, the area between the masonry and the window, or the window reveal. Thus, self-adhesive cold protection films of this type only reduce heat loss to a limited extent.

[0007] Thermal blinds that can be mounted on windows are also known. These serve both to protect the room from excessive heat caused by the sun's rays on warm summer days and to ensure that the heat stays in the room during the winter months or cooler seasons instead of escaping. Typical thermal blinds have a silver coating on the back or on the outward-facing side of the thermal blind. This silver coating reflects sunlight and prevents it from penetrating the room. Conversely, warm room air does not cool down too much because it is not directed directly past the cold window pane. In this case, the thermal blind acts as a kind of barrier. The disadvantage of thermal blinds is that the silver coating makes them opaque.In addition, thermal blinds do not have any sealing elements on the sides or on the lower edge, which means that the room air can flow mainly from the sides and / or from below into the space between the thermal blind and the window panes.

[0008] DE 20 2011 104 508 Ul describes a heat protection film window that shows a removable window frame with a suspended heat protection film. The window frame consists of an upper and lower suspension strip and side frame timbers and is clamped to the outer wall of the building between the window sill and the window lintel by means of spring force. The window frame can be put together using dowels and is dimensioned in such a way that it covers the wall opening beyond the window reveal. The heat protection film in this case is designed as a film with enclosed air cushions or air bubbles and is attached to the upper and lower suspension strips of the window frame. The disadvantages are, on the one hand, the suspension of the thin heat protection film in the suspension strips and, on the other hand, the lack of sealing against the wall, the window sill and the window lintel. In addition, the film with enclosed air cushions or air bubbles reduces the heat transfer to the wall.Air bubbles provide a clear view through the heat protection film to the outside.

[0009] Furthermore, DE 31 08 796 C2 discloses a device for sealing windows or doors installed in wall openings, comprising at least one material web blank made of a thin, crystal-clear plastic film, an upper horizontal rail in which the material web blank is suspended so as to be movable in a straight line, and a vertical rail designed as a step rail, which is attached immediately adjacent to the two vertical edges of the wall opening, wherein the first step forms a first, internal fastening section for fastening a first material web blank and the second step forms a second, external fastening section for fastening a second material web blank. The material web blank is fastened to the fastening section by means of a hook-and-loop fastener.Furthermore, the device either has a horizontally running bottom rail or the material web cutout is equipped with a bottom seam at its lower edge into which a lead chain is inserted. The disadvantage here is that the production of the material web cutout is cost-intensive and extremely complex. On the one hand, a reinforcement must be added to the upper end to prevent the thin material web cutout from tearing when suspended from the horizontal rail. On the other hand, Velcro strips must be attached to the respective long sides. Depending on the design, the lower edge of the material web cutout must also be designed as a bottom seam. In addition to the complex production of the material web cutout, a Velcro fastener does not have good sealing properties.

[0010] Finally, DE 26 21 254 A1 relates to a frame which can be additionally inserted into the window opening on the interior side and is covered with a transparent film. The frame consists of vertically running frame parts and horizontally running frame parts which are connected to one another at their corners. The frame is inserted into the window opening between the window sill and the window lintel and rests against the vertically running boundary surfaces of the window opening, the so-called window reveal, each with a seal. A snap-in or clamp connection is used to attach the frame to the window frame. The transparent film is attached to the frame, preferably to the vertically running frame parts, using an additional attachable clamping strip. The disadvantage is that the frame parts and the associated seals must be precisely adapted to the dimensions of the respective window reveal.

[0011] Description of the invention

[0012] The object of the present invention is therefore to provide a device that overcomes the disadvantages of the prior art. The device should ensure the best possible and most efficient thermal insulation, positively influence the room temperature and / or climate year-round, and be easy to install and simple and cost-effective to manufacture. This object is achieved according to the invention by the modular thermal protection device according to independent claim 1. Further advantageous aspects, details, and embodiments of the invention emerge from the dependent claims, the description, and the drawings.

[0013] The present invention provides a modular thermal insulation device for sealing windows, doors, or similar building elements installed in wall or building openings, comprising a mounting frame that can be mounted on the inside of the room on the wall or masonry of the building and at least partially surrounds the wall and building opening, and a transparent film that closes the wall or building opening, which is stretched by means of the mounting frame and held along the wall or building opening, wherein the mounting frame has at least one elongated sealing element for sealing the mounting frame from the wall or building opening, which is arranged between the wall of the building and the mounting frame. In a preferred embodiment, the sealing element is designed in the form of a brush seal.

[0014] The great advantage of the thermal insulation device according to the invention is that the thermal insulation device is not inserted into the wall or building openings or even fastened to the window or door frame, but is mounted on the inside masonry surrounding the wall or building openings, i.e. the thermal insulation device is designed in such a way that it extends beyond the wall or building openings so that the mounting frame can be fastened to the inside masonry or the inside wall of the building. The wall or building opening is therefore completely covered by the thermal insulation device. Advantageously, this does not require the frame elements to be precisely adapted to the inside dimensions of the building opening. When the thermal insulation device is installed, an air space or air chamber is created between the window and the interior of the building by means of the thermal insulation device, which acts as a heat insulator.Insulation layer or insulation chamber or insulation room. By attaching the thermal insulation device to the interior masonry, a particularly large insulation space is created, since essentially the entire depth of the reveal, in particular the door or window reveal, is utilized for the size of the insulation room. The larger the air-filled insulation space between the window or door and the thermal insulation device, the better the thermal insulation properties and the lower the energy or heat losses at the windows or doors. The energy losses at doors and windows can be reduced by up to 30%, for example, using the thermal insulation device according to the invention, compared to doors and windows without this thermal insulation device. Improved thermal insulation at windows and / or doors also leads to considerably lower energy costs and, in some cases, massive savings in heating costs.

[0015] Not only is the improved thermal insulation of windows, doors or similar building elements a major advantage, but the draft that regularly occurs due to leaks around the window or door can also be significantly reduced. Many people find drafts in the area of ​​windows and doors unpleasant and annoying. This draft is often caused by windows or doors warping over the years or by cracks or gaps in the masonry of the wall or building opening, such as cracks in the window reveal, window lintel or window sill. Cracks or gaps can also occur along expansion joints that are installed between window or door frames and the masonry for sealing and thermal insulation.In addition, expansion tapes or expansion pastes can swell to varying degrees during the installation of windows and doors, which means that the insulation or thermal insulation properties can vary or fluctuate greatly along a expansion tape.

[0016] The modular thermal insulation device now comprises a circumferential seal, which is realized by at least one elongated sealing element, preferably by several sealing elements. Preferably, each part of the mounting frame, such as the individual frame parts or the roller shutter box-like holding device, has a separate elongated sealing element. The elongated sealing elements serve to seal the mounting frame against the wall or building opening. That is, when the thermal insulation device is installed, the elongated sealing elements rest on the masonry surrounding the wall or building opening.

[0017] The elongated sealing element is particularly preferably designed as a brush seal, foam seal, or rubber seal. A brush seal is a contact seal comprising a carrier element, such as a sealing body, head, or strip, and a large number of thin wires or fibers attached to the carrier element. The seal consisting of a large number of wires or fibers adapts to the surface to be sealed. The use of a brush seal as an elongated sealing element has the advantage that it achieves a good seal between the mounting frame and the masonry despite unevenness on the surface of the masonry and / or sloping walls, as is often the case in older buildings. On the one hand, the brush seal therefore prevents the air released by the masonry orOn the one hand, drafts flowing through the building opening toward the building's interior are minimized, and on the other hand, a particularly well-sealed insulation space is provided. With a flat masonry surface, the use of a foam or rubber seal enables optimal sealing.

[0018] Particularly preferably, the transparent film is at least partially, preferably completely, coated to shield against UV rays. The film coated in this way has a light transmittance of less than 5%, in particular less than 1%, in the ultraviolet or UV range. The transparent film with a UV coating thus offers strong protection against premature fading of objects in the building, in particular furnishings such as carpets, furniture or pictures, etc., or textiles such as curtains, clothing, etc. Accordingly, these objects can be exposed to sunlight for significantly longer periods before the first signs of fading appear.

[0019] Another advantage is that the transparent film is translucent or transparent.

[0020] It has a light transmission in the visible range of greater than 70%, preferably greater than 80%, and especially greater than 85%. Consequently, the film is crystal-clear despite the UV coating and ensures a distortion-free view to the outside.

[0021] A further advantage is that the transparent film is extremely thin, with a thickness of only between 0.001 mm and 1 mm, preferably between 0.003 mm and 0.1 mm. Depending on the intended use, the transparent film can be single-layered or multi-layered, particularly two- or three-layered. Since the thermal insulation device is not used on the exterior of the building, but rather inside the building, the transparent film does not have to withstand particular environmental influences such as rain, snow, wind, or even gusts of wind or storms. Consequently, an extremely thin film can be selected, which is stretched by the mounting frame.

[0022] Particularly preferably, the transparent film and / or the brush seal is preferably detachably fastened to the mounting frame by means of at least one piping, adhesive and / or clamping connection.

[0023] In a first particularly advantageous embodiment, the mounting frame is designed as a type of tensioning frame and covered with the transparent film. For this purpose, the individual frame parts each have a groove-shaped, second receiving section in which the transparent film is held by means of a clamping means, such as a piping or piping tape. To cover the mounting frame, the transparent film is first placed in the groove of the second receiving section before the piping tape is pressed into the groove. The transparent film is then clamped to the mounting frame. A piping roller or piping pusher is particularly suitable as an aid for pressing the piping tape into the groove of the second receiving section. By loosening or pulling the piping tape out of the groove, the transparent film can be removed again and replaced if necessary.This allows for easy replacement of damaged or perforated films. The replaceability of the film also provides a sustainable thermal insulation device.

[0024] The mounting frame particularly preferably has a plurality of frame parts. First and foremost, the mounting frame has four frame parts which are connected to one another at their corners and form a stable, closed frame. For example, the mounting frame has a first lateral frame part, a second lateral frame part opposite the first lateral frame part, a third frame part connecting the first and second lateral frame parts at the upper end, and a fourth frame part connecting the first and second frame parts at the lower end, with the first to fourth frame parts forming a preferably closed mounting frame. In other words, the mounting frame in this embodiment consists of two vertically running frame parts and two transversely running frame parts. The frame parts are all at the edge area of ​​the masonry, which forms the wall or

[0025] The frame is mounted on a wall or building opening that surrounds it or borders it. It is also conceivable that the frame components can be individually adjusted to the size and / or width of the wall or building opening.

[0026] The frame components are advantageously made of plastic, wood, or metal, especially aluminum or stainless steel. Plastic or aluminum frame components are particularly easy and cost-effective to manufacture. Extruded aluminum frame components are particularly advantageous. This not only makes the frame components very lightweight, but also ensures high stability and durability.

[0027] Preferably, the frame parts are designed in the form of frame profile elements or frame hollow profile elements, wherein each of the frame profile elements or frame hollow profile elements has, over its longitudinal extent, at least one first receiving section for receiving and fastening elongate sealing elements, in particular brush seals, and at least one second receiving section for receiving and fixing and / or guiding the transparent film.

[0028] In a first embodiment, each frame profile element has a support surface facing the masonry and an opposite upper side or visible side, as well as two spaced-apart, groove-shaped receiving sections, namely a first receiving cutout into which the brush seal can be pressed in and releasably fastened, and a second receiving section in which the transparent film can be releasably fastened. The film and / or the brush seal is releasably fastened in the respective receiving section by means of a piping and / or clamping connection. Alternatively, both the film and the brush seal can be fastened using adhesive or a preferably double-sided adhesive tape. In particular, the brush seal can be designed as a self-adhesive brush seal, so that its adhesive surface can be fastened directly in the groove-shaped opening of the first receiving section.

[0029] In order to achieve the best possible seal between the mounting frame and the masonry, the mounting frame is designed such that, in the assembled state, it has at least one first, circumferential, groove-shaped receiving opening for attaching the brush seal and at least one second, circumferential, groove-shaped receiving opening for attaching the film. Depending on how the brush seal is installed, it can be designed as a single piece or in one piece, e.g. as a brush sealing strip that is pressed into the fully assembled mounting frame. Alternatively, several sealing elements or brush seals can be provided, so that, for example, each frame section is equipped with a separate brush seal. Because the brush seal is detachably attached, it can be exchanged and replaced at any time.In general, the advantage of the modular thermal protection device is that defective and / or worn and / or damaged components, such as brush seals, transparent film, frame parts, corner connectors, etc., can be easily exchanged and replaced.

[0030] In yet another alternative embodiment, a roller shutter box-like holding device with at least one shaft for rolling up or unrolling the transparent film is provided, wherein the roller shutter box-like holding device can be arranged either in the upper or lower area of ​​the thermal insulation device or in the lateral area of ​​the thermal insulation device. Depending on the design variant, the roller shutter box-like holding device replaces either the upper or third frame part or the lower or fourth frame part of the mounting frame or one of the two lateral frame parts. The roller shutter box-like holding device is preferably located at the top, i.e. in the area of ​​the window lintel, so that the user simply has to pull the transparent film downwards, i.e. towards the windowsill, when in use. The film can therefore be rolled up or unrolled from the roller shutter box-like holding device like a type of roller blind.The shaft of the roller shutter box-like holding device can be driven manually or by means of a drive, such as an electric motor, stepper motor or similar drive. A control unit can also be provided to control the drive. The control unit can comprise a timer which is configured such that the film is automatically rolled up or unrolled by means of the shaft depending on the time of day. To ensure that the transparent film is always guided during rolling up or unrolling, the lateral frame parts, namely the first and second frame parts, each have a lateral guide groove facing the transparent film. The guide groove extends essentially over the entire length of the respective frame part, so that the film covers the entire wall or building opening when extended.The guide groove on the first and second frame parts serves to ensure that the transparent film is guided laterally and held securely during the rolling and unrolling movement.

[0031] A coupling element can be arranged at the free end of the transparent film in order to be able to hang or fasten the film, when fully extended or in its end position, on the lower, fourth frame part or a holder or counter-coupling element in the area of ​​the window sill. It is conceivable that the coupling element at the lower edge of the film is magnetic or magnetizable and that the lower, fourth frame part is magnetic or magnetizable. The coupling element can thus be releasably fastened to the lower, fourth frame part by means of magnetic means. In an alternative embodiment, the connection between the coupling element and the area on the window sill and / or the lower, fourth frame part is made by means of at least one eyelet / loop and at least one hook or clamp, snap or click connection.

[0032] Furthermore, the roller shutter box-like holding device has at least one spring element, wherein the spring element is operatively connected to the shaft in such a way that the spring element is tensioned when the film is unrolled and can be driven when the film is rolled up by the restoring force of the spring element created when the transparent film is unrolled. The restoring force of the at least one spring element causes the film to be automatically rolled up again on the shaft, provided that the coupling element is released from the lower, fourth frame part or the corresponding holder or counter-coupling element by the user. Thus, the film that can be automatically rolled up onto the shaft provides a particularly user-friendly heat protection device. Furthermore, the film is safely stored in the rolled-up state and the window or door is freely accessible. This is particularly true when ventilating orWhen opening the door or window, it is necessary that the film can be easily wound up or removed from the wall or building opening. In particular, the frame parts are connected to one another and / or to the roller shutter box-shaped holding device on the adjacent end faces in a form-fitting and / or force-fitting or magnetic manner. Preferred types and means of connection include tongue and groove connections, dovetail connections, screw connections, magnetic connections, or angled corner connectors or corner panels. The corner connector in particular can have a first, groove-shaped receiving section for attaching the brush seal and a second, groove-shaped receiving section for attaching the film.In an advantageous embodiment, the mounting frame consists of four frame parts and four corner connectors, whereby the corner connectors serve to connect the corresponding frame parts.

[0033] To mount the modular thermal insulation device on the building's masonry or wall, several fastening devices are provided for mounting the mounting frame. Mounting brackets can be used as fastening devices, which are attached to the building's masonry or wall using adhesive, double-sided adhesive tape, screw connections, etc. The mounting brackets typically have at least one clamping screw, which secures the mounting frame to the mounting bracket.

[0034] Optionally, the fastening devices are designed as snap or click connectors. The snap or click connectors are designed in two parts, so that a first connecting part of the snap or click connector is attached to the masonry and a second connecting part is attached to the mounting frame. The snap or click connector is preferably made of metal, making it durable and robust.

[0035] In yet another alternative embodiment, the fastening devices are designed as magnetic or magnetizable fastening devices. Here, for example, a magnetizable first connecting part, such as a magnetizable plate / small plate and / or screw, is fastened to the masonry. In order to be able to releasably fasten the mounting frame thereto, the mounting frame, in particular the frame parts and / or the corner connectors, has a corresponding magnetic second connecting means, such as a magnetic plate / small plate or a magnetic coating. Conversely, the first connecting means on the masonry can also be magnetic and the second connecting means on the frame parts and / or corner connectors can be magnetizable. In particular with the magnetic fastening devices as well as with the snap or click connectors, each first connecting part on the masonry is assigned a second connecting part on the mounting frame.

[0036] No special tools are required to install the modular thermal insulation device on the masonry or wall. This makes installation extremely simple. Attaching the modular thermal insulation device to the inside of the building offers additional advantages. Especially for tenants who are only permitted to make changes to the facade or exterior of the building under certain conditions, thermal insulation devices that can be attached to the inside of the room's windows and doors represent a particularly simple way to reduce energy and heat loss through the windows and doors. Even in listed buildings, structural measures and / or changes to the facade or exterior of the building cannot be carried out without further ado. The thermal insulation device according to the invention, on the other hand, can be easily attached to the inside of the building, as there are no requirements to be met.

[0037] For thermal insulation of a wide window or even a wide window front, multiple thermal protection devices can be provided. These are arranged adjacently or directly next to each other to completely cover the wide wall or building opening. For example, two or more thermal protection devices can be arranged directly next to each other. With two thermal protection devices, the second frame part of the first mounting frame borders directly on the first frame part of the second mounting frame. The wider the window or window front, the more thermal protection devices can be arranged next to each other.

[0038] Further developments, advantages, and possible applications of the invention will become apparent from the following description of exemplary embodiments and from the figures. All described and / or illustrated features, individually or in any combination, are fundamentally part of the invention, regardless of their summary in the claims or their reference back to them.

[0045] Ways to implement the invention

[0046] Fig. 1 shows, with reference number 10, a modular thermal insulation device for sealing windows, doors or similar building elements inserted into wall or building openings 12. While the masonry of a building generally has good insulating properties, windows, particularly those with inefficient single glazing, have extremely low insulation values. The modular thermal insulation device according to the invention serves to mount the mounting frame, which carries or is covered with the transparent film, on the masonry surrounding the building opening. In this case, an air space or air chamber is created between the window and the actual interior of the building, with the enclosed air serving as a thermal insulator. The air-filled air space or air chamber interrupts the heat flow, which is directed from the inside to the outside during the cold season, since both the special transparent film and the air-filled air space or air chamberAir chamber has poor thermal conduction properties.

[0047] The modular thermal insulation device 10 can be mounted on the inside of the room, on the wall of the building. The thermal insulation device 10 consists of a mounting frame 20 which at least partially, preferably completely, surrounds the wall or building openings 12. The wall or building opening 12 is generally a breakthrough in the masonry into which a door or window is inserted to close the wall or building opening 12. If a window is inserted into the wall or building opening 12, the vertical cut surfaces created in the masonry by creating the wall or building opening 12 are referred to as the reveal or window reveal, the upper cut surface is referred to as the window lintel, and the lower cut surface is referred to as the window base. The wall or building opening 12 is surrounded by the masonry on its circumference. The thermal insulation device 10 is not inserted into the wall or building opening, but is attached to the wall or building opening.

[0048] The thermal insulation device 10 is fastened to the edge area surrounding the building opening 12. By fastening it to the building's masonry, an extremely large space is created between the thermal insulation device 10 and the window or door, extending across the entire depth t of the reveal or window reveal. Thus, the size of the insulation space depends significantly on the thickness of the masonry. Compared to conventional thermal insulation devices, which are arranged directly on the window frame, the thermal insulation device according to the invention provides a significantly larger space or insulation space.

[0049] Furthermore, the modular thermal protection device 10 has a transparent film 30 which closes the wall or building opening 12 and is held on the mounting frame 20 or stretched by the mounting frame 20. Figure 1 shows a mounting frame 20 in which the film 30 is clamped and held along the wall or building opening 12. The film 30 is a transparent film, in particular a clear film. The film 30 is preferably provided with a coating for shielding against UV rays, in particular UV-A and UV-B rays. A film 30 with a UV coating serves on the one hand as fading protection for valuable furniture and textiles, and also offers good thermal protection and protects against aggressive UV radiation.Despite the UV coating, the film 30 is still crystal-clear, with the film preferably having a light transmittance in the visible range that is greater than 70%, preferably greater than 80%, in particular greater than 85%. In contrast, the light transmittance of the film 30 in the ultraviolet range, i.e., the UV range, is less than 5%, in particular less than 1%.

[0050] Furthermore, the film 30 is an extremely thin, yet tear-resistant film. The thickness d of the film 30 is preferably between 0.001 mm and 1 mm, preferably between 0.003 mm and 0.1 mm.

[0051] The mounting frame 20 also comprises at least one elongate sealing element 40, which seals the mounting frame 20 against the wall or building opening 12. In order to create the most effective seal possible, a brush seal is used as the elongate sealing element 40. A brush seal is characterized by the fact that, due to its special design, it can seal extremely well even against uneven surfaces and / or sloping walls. The brush seal consists of a carrier element, such as a sealing body or head or strip, and a plurality of thin wires or fibers fastened to the carrier element. Figure 4 shows a brush seal which is received in the receiving section provided on the mounting frame. The brush seal therefore seals between the mounting frame 20 and the masonry or building wall.from the wall, creating a closed, air-filled space between the window / door frame and the thermal insulation device 10. The air-filled space serves as an insulation space or chamber. Due to its low thermal conductivity, the air trapped in the insulation space acts as an insulator and prevents heat from being quickly released through the window. Therefore, the larger the insulation space, the greater the amount of air trapped within it, and the better the insulation against cold.

[0052] As shown in the embodiment according to Figure 1, the mounting frame 20 has a plurality of frame parts 21, 22, 23, 24 which are connected to form a closed frame by means of suitable connecting means. The closed mounting frame 20 in Figure 1 has a first lateral frame part 21, a second lateral frame part 22 opposite the first lateral frame part 21, a third frame part 23 connecting the first and second lateral frame parts 21, 22 at the upper end, and a fourth frame part 24 connecting the first and second frame parts 21, 22 at the lower end. When assembled, the four frame parts 21, 22, 23, 24 form a closed and stable frame. The frame parts 21, 22, 23, 24 surround the wall or building opening 12 and are mounted to the masonry. The mounting frame is preferably designed as a type of blind or tension frame.The frame parts 21, 22, 23, 24 are preferably made of plastic, wood or metal, in particular aluminum or stainless steel.

[0053] In order to be able to attach the seal to the mounting frame 20 on the one hand, and to fasten the transparent film 30 to the mounting frame 20 on the other, the frame parts 21, 22, 23, 24 are designed in the form of frame profile elements or hollow frame profile elements. For fastening the brush seal, at least one first, groove-shaped receiving section 26 is provided on each frame profile element, wherein the receiving section is open on the side facing the masonry. The first receiving section 26 of each frame part 21, 22, 23, 24 extends essentially over the entire length of the respective frame part and is designed such that the brush seal can be received and fastened therein.

[0054] In addition to the first receiving section 26, a second, groove-shaped receiving section 27 is provided, which is inserted into the respective frame hollow profile element at a distance from the first receiving section 26 and serves to fasten the transparent film 30 to the mounting frame 20. Figure 4 shows that the first and second receiving sections 26, 27 are arranged at a distance from one another and run parallel to one another. The second receiving section 27 extends essentially over the entire length of the respective frame part and is designed such that the transparent film 30 can be received therein and preferably clamped therein.

[0055] The production of such frame profile elements or frame hollow profile elements by means of injection molding or extrusion is particularly simple and cost-effective.

[0056] The fastening of the film 30 to the mounting frame 20 is not shown in the figures. The film 30 is advantageously stretched over the assembled mounting frame 20, with the film ends 30 being placed in the respective groove of the second receiving section 27. Preferably, a piping or piping tape is used, with which the film ends are clamped in the respective second receiving section 27. However, other fastening methods for fastening the film 30 are also conceivable. For example, the film 30 can also be fastened in the respective second receiving section by means of an adhesive connection or double-sided adhesive tape. The film 30 can also have a self-adhesive edge strip.

[0057] Like the film 30, the brush seal can also be attached to the respective first receiving section 26 by means of a clamping connection or adhesive connection. Self-adhesive brush seals can also be used, which can be attached to the first receiving section 26 in a particularly simple manner.

[0058] Figure 4 shows a detailed view of two adjacent thermal protection devices 10. Multiple thermal protection devices 10 can be useful for covering wide windows or large window fronts. The two frame parts of a first thermal protection device 10 and a second thermal protection device 10 directly adjoin one another, with each of the thermal protection devices 10 having an independent or separate brush seal. The respective frame parts 21, 24 of the first thermal protection device 10 and the respective frame parts 22, 24 of the first thermal protection device 10 are connected to one another at their abutting sides or abutting end faces by means of a suitable connecting means, in particular a corner connector 28.Optionally, the adjacent end faces of the frame parts 21, 22, 23, 24 can be connected to one another in a form-fitting and / or force-fitting or magnetic manner, in particular by means of a tongue-and-groove connection, dovetail connection, screw connection and magnetic connection.

[0059] When the mounting frame 20 is assembled, the brush seal forms a circumferential seal so that the insulating space between the window and the thermal protection device is sealed as well as possible.

[0060] For mounting the thermal insulation device 10 on the masonry, fastening devices 60 are also provided, which can be designed in a wide variety of ways. Figure 2, for example, shows a fastening device 60 in the form of a fastening bracket. The fastening bracket 60 is preferably fastened to the wall using conventional screws. A corner of the mounting frame 20 is then positioned in the corresponding fastening bracket 60 and fixed to the fastening bracket 60 using at least one clamping screw. Alternatively, the fastening device 60 can be designed as a magnetic fastening device, namely with a magnetic first fastening part and a magnetic or magnetizable second fastening part that interacts with the latter, or vice versa. Further alternatively, hinge-like fastening devices can also be provided, at least laterally.

[0061] Figure 4 shows a corner connector 28 having a magnetic first fastening part on the surface facing the wall, with the corner connector 28 being assigned a magnetizable or magnetic fastening part (not shown) on the wall. The second fastening part located on the wall can be in the form of a screw, in particular an iron screw, a magnetic or magnetizable holding plate or plate. The corner connector 28 can also have a magnetic or magnetizable holding plate or plate, or optionally a magnetic or magnetizable coating. Alternatively, the fastening devices 60 can also be designed as snap-in or click-in connectors.

[0062] In an alternative embodiment, the film 30 is not held rigidly in the mounting frame 20, but is arranged to be movable in the vertical direction. For this purpose, the mounting frame 20 has, instead of the upper or lower frame part 23, 24, a roller shutter box-like holding device 50 with at least one shaft for rolling up or unrolling the transparent film 30. Typically, the roller shutter box-like holding device 50 is fastened to the masonry, specifically at the upper edge of the wall or building opening 12. By fastening the roller shutter box-like holding device 50 to the upper edge of the wall or building opening 12, the film 30 can be easily pulled or unrolled downwards, i.e. towards the window base, by the user. Conversely, the window or door can be made quickly accessible to the user by simply rolling up the film 30.The mounting frame 20 therefore does not need to be removed from the wall to access the window or door. Access to windows and doors is particularly important when ventilating rooms.

[0063] In this embodiment, the lateral frame parts 21, 22 each have a guide groove in which the transparent film 30 is laterally guided and securely held during the winding and unwinding movement. The respective guide groove guides the film 30 from the starting position, in which the film 30 is completely wound onto the shaft, to an end position at which the free end of the film 30 is completely extended or at which the free end of the film 30 forms a sealing connection with the lower frame part 24 or the window sill. A coupling element 32 is preferably arranged at the free end of the film 30, which can be designed, for example, in the form of a holding rail or as a film seam. The coupling element 32 serves to enable the film 30 to be suspended or fixed to the lower, fourth frame part 24 or a counter-coupling element in the area of ​​the window base.It is conceivable that the coupling element 32 at the lower edge of the film is magnetic or magnetizable, and the lower, fourth frame part 24 is magnetic or magnetizable. Thus, the coupling element 32 can be releasably attached to the lower, fourth frame part 24 by magnetic means. In an alternative embodiment, the connection between the coupling element and the area on the window sill and / or the lower, fourth frame part 24 is realized by means of at least one eyelet / loop and at least one hook, clamp, snap, or click connection.
