Abstract
Description
The present invention relates to a skirting board, a ceiling strip and a window or door frame insulation strip. From DE 10 2014 115 656 A1 a baseboard, a ceiling strip and a window or door frame insulation strip are known. The inventors have discovered that when such strips are designed with one or two protruding lips, these often break off during transport as well as during installation in the respective installation situation, and that this effect is particularly pronounced in autumn, winter and spring, and especially at sub-zero temperatures. It is therefore an object of the present invention to provide a baseboard, a ceiling strip and a window or door frame insulation strip in which the breaking off of the at least one protruding lip is prevented both during transport and during installation in the respective installation situation throughout the year and over all commonly occurring temperature ranges. This task is solved by the subject matter of the independent claims. Advantageous further developments arise from the dependent claims. A skirting board according to the invention for arrangement at a building transition between a lower wall end and an adjacent floor area comprises a base body (4), in particular with a quadrilateral cross-section, e.g. a substantially rectangular or substantially parallelogram-shaped cross-section, with a front, a back, a top and a bottom, or a base body, in particular with a triangular cross-section with a front, a back and a bottom; a lower projecting lip on the underside of the base body, in particular at the front end of the underside of the base body; and / or an upper projecting lip on the top of the base body, in particular at the front or rear end of the top of the base body;wherein the front and / or top of the base body, the front of the lower projecting lip and / or the front of the upper projecting lip form a visible area intended to point away from the lower wall end and the floor area in the position of the baseboard located at the transition between the lower wall end and the adjacent floor area; wherein the rear and / or bottom of the base body, the rear of the lower projecting lip and / or the rear of the upper projecting lip form a non-visible area intended to point towards the lower wall end and the floor area in the position of the baseboard located at the transition between the lower wall end and the adjacent floor area;wherein a layer, in particular a reinforcing layer or a support layer, is applied at least partially to the back side of the lower projecting lip and / or to the back side of the upper projecting lip, which has a more flexible material than the base material of the lower projecting lip and / or the upper projecting lip, in order to prevent the lower projecting lip and / or the upper projecting lip from tearing or breaking when the lower projecting lip and / or the upper projecting lip is deformed. A window or door frame insulation strip according to the invention for arrangement at the transition between the window or door frame and the building wall or reveal of a building wall, comprises a base body, in particular with a quadrilateral cross-section, e.g. a substantially rectangular or substantially parallelogram-shaped cross-section, with a front, a back, a top and a bottom, or a base body, in particular with a triangular cross-section with a front, a back and a bottom; a lower projecting lip on the underside of the base body, in particular at the front end of the underside of the base body; and / or an upper projecting lip on the top of the base body, in particular at the front or rear end of the top of the base body;wherein the front and / or the top of the base body, the front of the lower projection lip and / or the front of the upper projection lip form a visible area intended to point away from the window or door frame and the building wall or the reveal of the building wall in the position of the insulation strip arranged at the transition between the window or door frame and the building wall or the reveal of the building wall; wherein the rear and / or the bottom of the base body, the rear of the lower projection lip and / or the rear of the upper projection lip form a non-visible area intended to point towards the window or door frame and the building wall or the reveal of the building wall in the position of the insulation strip arranged at the transition between the window or door frame and the building wall or the reveal of the building wall;wherein a layer, in particular a reinforcing layer or a support layer, is applied at least partially to the back side of the lower projecting lip and / or to the back side of the upper projecting lip, which has a more flexible material than the base material of the lower projecting lip and / or the upper projecting lip, in order to prevent the lower projecting lip and / or the upper projecting lip from tearing or breaking when the lower projecting lip and / or the upper projecting lip is deformed. A ceiling trim according to the invention for arrangement at a building transition between an upper wall end and an adjacent ceiling area comprises a base body, in particular with a quadrilateral cross-section, e.g. a substantially rectangular or substantially parallelogram-shaped cross-section, with a front, a back, a top and a bottom; or a base body, in particular with a triangular cross-section with a front, a back and a bottom; an upper projecting lip on the top of the base body, in particular at the front end of the top of the base body; and / or a lower projecting lip on the bottom of the base body, in particular at the front or rear end of the bottom of the base body;wherein the front and / or the underside of the base body, the front of the upper projecting lip and / or the front of the lower projecting lip form a visible area intended to point away from the upper wall end and the ceiling area in the position of the ceiling trim located at the transition between the upper wall end and the adjacent ceiling area; wherein the rear and / or the top of the base body, the rear of the upper projecting lip and / or the rear of the lower projecting lip form a non-visible area intended to point away from the upper wall end and the ceiling area in the position of the ceiling trim located at the transition between the upper wall end and the adjacent ceiling area;wherein a layer, in particular a reinforcing layer or a support layer, is applied at least partially to the back side of the upper projecting lip and / or to the back side of the lower projecting lip, which has a more flexible material than the base material of the upper projecting lip and / or the lower projecting lip, in order to prevent the upper projecting lip and / or the lower projecting lip from tearing or breaking when the upper projecting lip and / or the lower projecting lip is deformed. According to a basic idea of the present invention, by applying at least a partial layer, in particular a reinforcing layer or a support layer, to the back of the lower and / or upper projection lip, which has a more flexible material than the base material of the lower and / or upper projection lip, the tearing or breaking of the lower and / or upper projection lip in the event of deformation is reliably avoided. This significantly improves the break-resistant deformability of the lower and / or upper projecting lip throughout the year and across all commonly occurring temperature ranges. Deformation of the protruding lip is understood to mean bending, compression, upsetting, stretching or a combination thereof. Internal tests have shown that such a layer, in particular a reinforcing and support layer, on the back of the lower and / or upper projecting lip ensures that it will not tear or break across the entire typical temperature range of -20° Celsius to +50° Celsius. Baseboard, ceiling, and window or door frame insulation strips are exposed to temperatures within this range during transport and in outdoor applications. Indoors, the temperature range to which baseboard, ceiling, and window or door frame insulation strips are exposed is less pronounced, especially at the lower end, and is typically above freezing. This significantly reduces or even completely avoids the breakage problem that occurs with conventional baseboard, ceiling, window or door frame insulation strips, both during transport and installation in the installation situation. The layer(s), especially the reinforcing or supporting layer(s), can be designed differently. However, all variants have in common that, due to the choice of material, the small thickness of the layer(s) or a combination thereof, they possess a flexibility that allows them to accommodate a deformation of the projecting lip, e.g., bending, compression, upsetting, stretching or a combination thereof, and to support the projecting lip in question from behind. This reliably prevents the material of the projection lip or at the transition from the projection lip to the main body from tearing or breaking. It should be emphasized at this point that the present invention also includes baseboard, ceiling and window or door frame insulation strips, in which only in the case of a projecting lip on the back side a layer, in particular a reinforcing layer or a support layer, is applied at least in some areas, which has a more flexible material than the base material of this projecting lip, in order to prevent this projecting lip from tearing or breaking when it is deformed. When all three types of moldings – baseboard, ceiling, and window or door frame insulation moldings – are referred to collectively below, the generic term "mold" is used. Typical heights of such strips range between 40 and 150 mm. The projecting lips can have a tapered width, especially towards their tip. The application, at least in part, of the layer, in particular the reinforcement layer or the support layer, to the back of the lower and / or upper projection lip, which has a more flexible material than the base material of the lower and / or upper projection lip, can be carried out in any suitable way, e.g. by back injection or by co-extrusion. According to a first embodiment of the baseboard, the back of the base body is designed to rest against the lower wall end in the position of the baseboard arranged at the transition between the lower wall end and the adjacent floor area. According to a first embodiment of the window or door frame insulation strip, the back of the base body is designed to rest against the building wall or the reveal of the building wall in the position of the insulation strip arranged at the transition between the window or door frame and the building wall or the reveal of the building wall. The embodiments and advantages described below apply to both the baseboard and the window or door frame insulation strip. The upper projecting lip can attach to the front end of the top of the base body and extend obliquely upwards and backwards from there, overlapping the rearward section of the top of the base body. The lower projecting lip can attach to the front end of the underside of the base body and extend obliquely forward and downward from there, overlapping the rearward section of the underside of the base body. This ensures a particularly advantageous seal to the lower wall end or the reveal or thermal insulation on the one hand, and to the floor area or the window or door frame on the other. The projection direction of the lower projection lip and / or the upper projection lip can form an angle of 0.5 - 89.5°, in particular of 30 - 80°, with the plane of the front of the base body or with the plane of the rear of the base body. The tip of the lower projecting lip and / or the upper projecting lip may be made of a soft plastic material, which is in particular softer than the base material of the lower projecting lip and / or the upper projecting lip, and which is in particular co-extruded with the base material of the lower projecting lip and / or the upper projecting lip. The boundary surface between the tip and the remaining area of the lower projecting lip and / or the upper projecting lip can essentially run perpendicular to the main extension direction of the lower projecting lip and / or the upper projecting lip. Such a tip allows the respective projecting lip to adapt more flexibly to the lower wall end / floor area, or to the wall or reveal area, or the window or door frame. The layer of the lower and / or upper projecting lip can extend over the entire back surface of the lower projecting lip and / or the entire back surface of the upper projecting lip. A layer extending over the entire back surface provides particularly high tear and break resistance. Alternatively, the layer of the lower and / or upper projecting lip can extend only over a central area and over a region of the back of the lower and / or upper projecting lip located towards the base body, leaving the tip of the lower and / or upper projecting lip exposed. This represents a particularly good compromise between the breakage and tear resistance of the projecting lip while simultaneously allowing the tip to be flexibly positioned. The layer of the lower and / or upper projecting lip can have two spaced-apart layer sections. Two or more spaced-apart layer sections can be used to support the areas that are most susceptible to breakage and tearing in practice. The first layer section can extend over a central area of the back side of the lower and / or upper projection lip. This supports the central section of the projection lip. The second layer section can extend over an area on the back side of the lower and / or upper projecting lip that is located towards the base body. Both the transition of the projecting lip to the main body and the middle section of the projecting lip are supported by corresponding layer sections. The layer of the lower and / or upper projecting lip, or the second layer section of the lower and / or upper projecting lip, can extend to the base body of the skirting board, in particular to the underside of the base body in the case of the lower projecting lip, and / or to the top of the base body in the case of the upper projecting lip, while covering the transition area between the lower projecting lip and / or the upper projecting lip and the base body. This provides particularly reliable protection for the transition area between the projecting lip and the base body, where, as the inventors have discovered, there is a particularly high risk of breakage and material tearing. The baseboard or window / door frame insulation strip can further comprise a separate layer section on the back of the base body, particularly in a central area of the back of the base body. Such a separate layer section reliably prevents splintering of the material on the back of the base body, for example, when a nail or screw is inserted for fastening. The layer can extend over the entire back side of the lower projecting lip, the entire back side of the upper projecting lip, and the entire back side of the base body, including the area of the top of the base body behind the upper projecting lip and the area of the bottom of the base body behind the lower projecting lip. This ensures that the entire back side of the projecting lips and the base body is supported by such a layer, preventing material breakage and tearing along the entire height of the strip. Alternatively, the layer can extend over a central and a region closer to the base body on the back side of the lower and upper projecting lips, leaving the tips of the lower and upper projecting lips exposed, and over the entire back side of the base body, including the area of the top of the base body behind the upper projecting lip and the area of the bottom of the base body behind the lower projecting lip. This provides support for almost the entire back side of the projecting lips and the base body, preventing material breakage and tearing along the entire height of the strip, possibly excluding the soft tips of the projecting lips. The following embodiments apply to all types of strips according to the invention: Baseboard, ceiling and window or door frame insulation strips: The base body can comprise a plastic material, in particular a foamed plastic material or a plastic composite material, in particular a foamed plastic composite material, e.g. a Wood Plastic Composite WPC, or a plastic mixture of different plastics, e.g. a rigid PVC+W-PVC mixture or a PP+TPE mixture. According to one variant, the layer has a soft plastic, in particular a thermoplastic elastomer TPE or a soft PVC, and can be co-extruded with the base body and the projecting lips. According to another variant, the layer has a foamed plastic material or a foamed plastic composite material, e.g. a Wood Plastic Composite (WPC) or a plastic mixture of different plastics, e.g. a rigid PVC+W-PVC mixture or a PP+TPE mixture, and can be co-extruded with the base body and the projecting lips. The flexibility arises from the material itself, and in principle, almost any layer thickness can be achieved. Typically, such a layer has a thickness of 0.3 to 0.5 mm. According to another variant, the layer comprises a plastic, in particular a rigid plastic such as polypropylene (PP), polyethylene (PE), or rigid PVC, and can be co-extruded with the base body and the projecting lips. The flexibility results from a small layer thickness, typically in the range of 0.2 to 0.4 mm. Such a thin layer can guarantee the required flexibility. As a general rule, the softer the plastic material chosen for the layer, the thicker the layer thickness can be, and vice versa. According to another variant, the layer is designed as a lacquer layer or as a foil layer, and can be suitablely applied to the base body and to the projecting lips. For the layer, a metal can even be chosen that has been suitablely applied to the base body and to the projecting lips, in which case the layer thickness must be chosen to be correspondingly small and is typically in the range of 0.1 - 0.4 mm, in particular 0.2-0.3 mm. The invention also relates to a building transition between a lower wall end and an adjacent floor area, with a skirting board of the type described herein arranged thereon, wherein the skirting board is arranged at the building transition such that the front and / or the top of its base body, the front of its lower projecting lip and / or the front of its upper projecting lip point away from the lower wall end and from the floor area and form a visible area, and that the back and / or the underside of its base body, the back of its lower projecting lip and / or the back of its upper projecting lip, on which at least partially a layer, in particular a reinforcing layer or a support layer, is applied, point towards the lower wall end and to the floor area and form a non-visible area;that the tip of the lower projecting lip rests against the floor area, and / or the tip of the upper projecting lip rests against the lower wall end. The aforementioned advantages and embodiments result for this version and will not be repeated here. The invention also relates to a building transition between a window or door frame and a building wall or the reveal of a building wall, with a window or door frame insulation strip of the type described herein arranged thereon, wherein the window or door frame insulation strip is arranged at the building transition such that the front and / or the top of its base body, the front of its lower projecting lip and / or the front of its upper projecting lip point away from the window or door frame and from the building wall or the reveal of the building wall and form a visible area, and that the back and / or the underside of its base body, the back of its lower projecting lip and / or the back of its upper projecting lip, on which at least partially a layer, in particular a reinforcing layer or a support layer, is applied,to the window or door frame and to the building wall or the reveal of the building wall and form a non-visible area; that the tip of the lower projecting lip rests against the window or door frame, and / or the tip of the upper projecting lip rests against the building wall or the reveal of the building wall. The aforementioned advantages and embodiments result for this version and will not be repeated here. The embodiments and advantages defined below relate to the ceiling strip and are fundamentally analogous to the embodiments and advantages described above for the baseboard and the window or door frame insulation strip, but with adjustments to the orientation of the upper and lower projecting lip and the installation situation being virtually reversed compared to the baseboard and the window or door frame insulation strip. The back of the base body is typically designed to rest against the upper wall end in the position of the ceiling strip located at the transition between the upper wall end and the adjacent ceiling area. The lower projecting lip can attach to the front end of the underside of the base body and extend from there to the rear and downwards, overlapping the rearward section of the underside of the base body. The upper projecting lip can attach to the front end of the top of the base body and extend obliquely forward and upward from there, overlapping the rearward section of the top of the base body. This ensures a particularly advantageous seal to the upper wall end on the one hand and to the ceiling area on the other. The projection direction of the lower projection lip and / or the upper projection lip can form an angle of 0.5 - 89.5°, in particular of 30 - 80°, with the plane of the front of the base body or with the plane of the rear of the base body. The tip of the lower projecting lip and / or the upper projecting lip may be made of a soft plastic material, which is in particular softer than the base material of the lower projecting lip and / or the upper projecting lip, and which is in particular co-extruded with the base material of the lower projecting lip and / or the upper projecting lip. The interface between the tip and the remaining area of the lower projecting lip and / or the upper projecting lip can run essentially perpendicular or oblique to the main extension direction of the lower projecting lip and / or the upper projecting lip. Such a tip allows the respective projecting lip to adapt more flexibly to the upper wall end or ceiling area. The layer of the lower and / or upper projecting lip can extend over the entire back surface of the upper projecting lip and / or the entire back surface of the lower projecting lip. A layer extending over the entire back surface provides particularly high tear and break resistance. The layer of the lower and / or upper projection lip can only extend over a central area and over a region on the back side of the upper projection lip and / or the lower projection lip that is located towards the base body, leaving the tip of the upper projection lip and / or the lower projection lip exposed. This represents a particularly good compromise between the fracture and tear resistance of the projection lip while simultaneously allowing the tip to be flexibly positioned. The layer of the lower and / or upper projecting lip can have two spaced-apart layer sections. Two or more spaced-apart layer sections can be used to support the areas that are most susceptible to breakage and tearing in practice. The first layer section can extend over a central area of the back side of the upper and / or lower projecting lip. This supports the central section of the projecting lip. The second layer section can extend over an area on the back side of the upper and / or lower projecting lip that is located towards the base body. Both the transition of the projecting lip to the main body and the middle section of the projecting lip are supported by corresponding layer sections. The layer of the lower and / or upper projecting lip, or the second layer section of the lower and / or upper projecting lip, can extend to the base body of the ceiling strip, in particular to the underside of the base body in the case of the lower projecting lip, and / or to the top of the base body in the case of the upper projecting lip, while covering the transition area between the lower projecting lip and / or the upper projecting lip and the base body. This provides particularly reliable protection for the transition area between the projecting lip and the base body, where, as the inventors have discovered, there is a particularly high risk of breakage and material tearing. The ceiling molding can also include a separate layer section on the back of the base body, particularly in a central area of the back of the base body. Such a separate layer section reliably prevents the material on the back of the base body from splintering, for example, when a nail or screw is inserted for fastening. The layer can extend over the entire back side of the lower projecting lip, the entire back side of the upper projecting lip, and the entire back side of the base body, including the area of the top of the base body behind the upper projecting lip and the area of the bottom of the base body behind the lower projecting lip. This ensures that the entire back side of the projecting lips and the base body is supported by such a layer, preventing material breakage and tearing along the entire height of the strip. Alternatively, the layer can extend over a central and a region closer to the base body on the back side of the lower and upper projecting lips, leaving the tips of the lower and upper projecting lips exposed, and over the entire back side of the base body, including the area of the top of the base body behind the upper projecting lip and the area of the bottom of the base body behind the lower projecting lip. This provides support for almost the entire back side of the projecting lips and the base body, preventing material breakage and tearing along the entire height of the strip, possibly excluding the soft tips of the projecting lips. The invention also relates to a building transition between an upper wall end and an adjacent ceiling area, with a ceiling strip of the type described herein arranged thereon, wherein the ceiling strip is arranged at the building transition such that the front and / or the underside of its base body, the front of its upper projecting lip and / or the front of its lower projecting lip point away from the upper wall end and from the ceiling area and form a visible area, and that the back and / or the top of its base body, the back of its upper projecting lip and / or the back of its lower projecting lip, on which at least partially a layer, in particular a reinforcing layer or a support layer, is applied, point towards the upper wall end and to the ceiling area and form a non-visible area;that the tip of the lower projecting lip rests against the upper wall end, and / or the tip of the upper projecting lip rests against the ceiling area. The invention is explained in more detail below with reference to exemplary embodiments and the accompanying figures. Fig. 1 shows a side view of a first strip according to the invention, comprising a base body and two projecting lips; Fig. 2 shows a side view of a second strip according to the invention, comprising a base body and two projecting lips; and Fig. 3 shows a side view of a third strip according to the invention, comprising a base body and two projecting lips. In Fig. 1, Fig. 2 and Fig. 3, the strips 2, 42 and 52 are each shown in their uninstalled delivery state. Fig. 1 shows a side view of a first baseboard, ceiling strip or window or door frame insulation strip, hereinafter referred to as strip 2, which has a base body 4, an upper projecting lip 18 and a lower projecting lip 20. Fig. 2 shows a side view of a second baseboard, ceiling strip or window or door frame insulation strip, hereinafter referred to as strip 42, which has a base body 4, an upper projecting lip 18 and a lower projecting lip 20. Fig. 3 shows a side view of a third baseboard, ceiling strip or window or door frame insulation strip, hereinafter referred to as strip 52, which has a base body 4, an upper projecting lip 18 and a lower projecting lip 20. The strips 2, 42 and 52 each have a base body 4 which, in the present, non-limiting embodiment, has a rectangular cross-section. Alternatively, other cross-sections are also possible, e.g., a parallelogram-shaped cross-section, a cross-section of an irregular quadrilateral where, for example, the front tapers upwards towards the back and the material thickness thus decreases from bottom to top, or a triangular cross-section. The basic body 4 with rectangular cross-section according to the present embodiment has a longer front side 6, a shorter top side 8, a longer back side 10 and a shorter bottom side 12. The front side 6 and the back side 10 extend parallel to each other. The upper projecting lip 18 is positioned at the transition area between the front surface 6 and the top surface 8. This lip projects obliquely upwards and backwards at an angle of 30° to 80°, in the present embodiment approximately 50°, relative to the vertical plane of the front surface 6 of the base body 4. The length of the upper projecting lip 18 is selected such that, in the uninstalled delivery state of the strip 2, 42, 52, the upper rear tip 19 of the upper projecting lip 18 lies a short distance behind the vertical plane formed by the rear surface 10 of the base body 4 of the strip 2, 42, 52. The lower projecting lip 20 is arranged at the transition area between the front surface 6 and the underside 12. This lip projects at an angle of 30 to 80°, in the present embodiment at approximately 45°, relative to the vertical plane of the front surface 6 of the base body 4. In the present, non-limiting embodiment, the lower projecting lip 20 has a slightly curved profile. The Wegrag lips 18, 20 can exhibit a tapering width, especially when viewed towards their tip. The front lower tip 22 of the lower projecting lip 20 is offset forward relative to the plane of the front surface 6 of the base body 4, in particular by approximately 2 to 3 times the width of the base body, viewed from the rear surface 10 to the front surface 6. Likewise, the front lower tip 22 of the lower projecting lip 20 is offset downward relative to the plane of the underside 12 of the base body 4 of the strip 2, in particular by approximately 1 to 3 times the width of the base body 4, viewed from the rear surface 10 to the front surface 6. These values are, of course, only examples; other dimensions are also possible, e.g., 0.2 to 3 times the width of the base body 4. The upper rear tip 19 of the upper projecting lip 18 and the lower front tip 22 of the lower projecting lip 20 are formed by a softer plastic area which is co-extruded with the material of the remaining upper projecting lip 18, the remaining lower projecting lip 20 and the base body 4 in order to be able to conform more flexibly to the lower or upper wall end, the floor area, the upper ceiling area, the wall or reveal area or the window or door frame. The front side 6 of the base body 4, the front side of the lower projecting lip 20 and the front side of the upper projecting lip 18 form a visible area. The back 10 and the underside 12 of the base body 4, the back of the lower projecting lip 20, the top 8 of the base body 4 and the back of the upper projecting lip 18 form a non-visible area. In the first strip 2, a layer, in particular a reinforcing or support layer, is applied at least partially to the back of the lower projecting lip 20 and to the back of the upper projecting lip 18. In the first strip 2 from Fig. 1, this layer is formed in the form of two separate layer areas 30, 32, of which the first layer area 30 is applied to the underside 12 of the base body 4 and to a large part of the back of the lower projecting lip 20 and of which the second layer area 32 is applied to a part of the back of the upper projecting lip 18. The first layer area 30 extends in particular over the section of the underside 12 located behind the lower projecting lip 20 and over the majority of the back of the lower projecting lip 20 up to the interface where the soft front lower tip 22 is attached. The second layer area 32 extends from the point on the upper surface 8 of the base body 4 where the upper projecting lip 18 is attached, to an approximately central position on the back side of the upper projecting lip 18, in particular to the interface where the soft rear upper tip 19 is attached. In the second strip 42 from Fig. 2, the layer, in particular the reinforcement or support layer, is formed in the form of two separate cut sections 34 and 36 at the lower projecting lip 20 and a further layer section 32 at the upper projecting lip 18. The first layer section 34 on the lower projecting lip 20 extends over a central rear region of the lower projecting lip 20. The lower end of the first layer section is spaced from the interface with the soft front lower tip 22 of the lower projecting lip 20. Its upper end is a short distance from the lower end of the second layer section 36. The second layer section 36 of the lower projecting lip 20 extends over the transition region between the upper end of the lower projecting lip 20 and the horizontal underside 12 of the base body 4, thus covering it rearward. The second layer section 36 forms a curvature that follows the curvature of the transition between the underside 12 of the base body 4 and the upper end region of the lower projecting lip 22. The rear layer section 32 on the upper projecting lip 18 extends over part of the rear region of the upper projecting lip 18. Its lower end is located at the lowest point of the straight rear region of the upper projecting lip 18, after the curvature to the upper surface 8 of the base body 4. Its upper end is spaced a short distance from the interface to the soft rear upper tip 19. Furthermore, the layer, in particular the reinforcement or support layer in the second baseboard 42 from Fig. 2, comprises a central rear layer section 38 on the back side 10 of the base body 4. In the third rib 52 according to Fig. 3, the rear layer 54 extends over a large part of the rear side of the lower projecting lip 20, over the area of the underside 12 located behind the lower projecting lip 20, over the entire rear side 10 of the base body 4, over the upper side 8 of the base body 4, in particular over the entire area of the upper side 8 of the base body 4 located behind the upper projecting lip 18, and over part of the rear side of the upper projecting lip 18. In particular, the interface with the soft front lower tip 22 of the lower projecting lip 20 forms the lower end of the rear layer 54. Likewise, the interface with the soft rear upper tip 19 of the upper projecting lip 18 forms the upper end of the rear layer 54. When the strip is designed as a baseboard 2, the visible area is intended to point away from the lower wall end and the floor area in the position of the baseboard 2 located at the transition between the lower wall end and the adjacent floor area, and the non-visible area is intended to point towards the lower wall end and the floor area in the area of the baseboard 2 located at the transition between the lower wall end and the adjacent floor area. When the strip is designed as a baseboard 2, the back of the base body 10 is intended to lie against the lower wall end in the position of the baseboard 2 located at the transition between the lower wall end and the adjacent floor area. The installation of the skirting board 2 can be easily visualized by imagining that the back 10 of the base body 4 rests against the lower wall end, that the tip of the lower projection lip 20 rests on the floor area, and that the tip of the upper projection lip 18 rests against the lower wall end. The skirting board 2 thus protects the building transition between the lower wall end and the adjacent floor area, while the projection lips 18 and 20 prevent moisture and / or dirt from penetrating the area behind the skirting board 2. The strips 2, 42, 52 are also suitable as ceiling strips for placement at the transition between an upper wall end and an adjacent ceiling area. In this case, the strips 2, 42 and 52 are each to be arranged in a horizontal, downward-rotated position at such a transition such that the back side 10 points towards or rests against the upper wall end, that the projecting lip 18 is a lower projecting lip and also rests against the upper wall end, and that the projecting lip 20 forms an upper projecting lip and rests against the ceiling area. Similarly, strips 2, 42 and 52 can also be used as window or door frame insulation strips for placement at the transition between the window or door frame and the building wall or reveal of a building wall. In this case, the strip 2, 42, 52 rests with its rear side 10 against the building wall or the reveal. The rear upper projection lip 18 rests against the building wall or reveal, and the front lower projection lip 20 rests against the window or door frame. All described strips 2, 42, 52 can be attached to the building transition in a suitable manner, e.g. by gluing the back 10 to the lower foot area (baseboard), to the upper wall end (ceiling strip) or to the building wall or reveal (window or door frame insulation strip), or e.g. by nails that extend through the base body 4 into the floor area / lower wall area (baseboard), into the ceiling area / upper wall end (ceiling strip) or into the building wall or reveal / window or door frame (window or door frame insulation strip). The layer(s) applied to the reverse side of the projecting lips 18, 20, in particular reinforcing or support layers 30, 32 or 34, 36, 32 or 54, reliably prevents tearing or breakage of the material of the projecting lip 18, 20 or at the transition from the projecting lip 18, 20 to the main body 4 when the projecting lip 18, 20 is deformed, e.g., by bending, compression, upsetting, pulling, or a combination thereof. This allows for particularly flexible and precise installation of the strips with conforming deformation of the projecting lips in the respective installation situation, and ensures a particularly reliable seal of the area behind the strip against penetrating moisture and dirt. The layer(s) applied to the rear of the projecting lips 18, 20, in particular reinforcing or support layers 30, 32 or 34, 36, 32 or 54, can each also be referred to as a reinforcing or support layer which reinforces or supports the projecting lip 18, 20 and the transition between the projecting lip 18, 20 and the main body 4 from the rear. The base body 4 of the strips 2, 42, 52 comprises in particular a plastic material, especially a foamed plastic material or a plastic composite material, especially a foamed plastic composite material, e.g. a Wood Plastic Composite WPC or a plastic mixture of different plastics, e.g. a rigid PVC+W-PVC mixture or a PP+TPE mixture. The layer(s), in particular reinforcing or support layers 30, 32 or 34, 36, 32 or 54, can be designed differently. However, all variants have in common that, due to the choice of material, the small thickness of the layer(s), or a combination thereof, they possess a flexibility that allows them to accommodate deformation of the projecting lip, e.g., during bending, compression, upsetting, stretching of the projecting lip 18, 20, or a combination thereof, while reliably preventing tearing or breakage of the material of the projecting lip 18, 20 or at the transition from the projecting lip 18, 20 to the main body 4. According to one variant, the layer comprises a soft plastic, in particular a thermoplastic elastomer (TPE) or a flexible PVC, and can be co-extruded with the base body 4 and the projecting lips 18, 20. According to another variant, the layer comprises a foamed plastic material or a foamed plastic composite material, e.g., a wood-plastic composite (WPC) or a plastic mixture of different plastics, e.g., a rigid PVC + WPC mixture or a PP + TPE mixture, and can be co-extruded with the base body 4 and the projecting lips 18, 20. In this case, the flexibility results from the material, and in principle, almost arbitrarily large layer thicknesses can be provided. Typically, such a layer has a thickness of 0.3 to 0.5 mm. According to another variant, the layer comprises a plastic, in particular a rigid plastic, especially polypropylene (PP), polyethylene (PE), or rigid PVC, and can be co-extruded with the base body 4 and the projecting lips 18, 20. The flexibility results from a small layer thickness, typically in the range of 0.2 to 0.4 mm. Such a thin layer can guarantee the required flexibility. Generally speaking, the softer the plastic material chosen for the layer, the thicker the layer can be, and vice versa. According to another variant, the layer is designed as a lacquer layer or as a foil layer, and can be suitably applied to the base body 4 and to the projecting lips 18, 20. For the layer, a metal can even be chosen that has been suitably applied to the base body 4 and to the projecting lips 18, 20, whereby in this case the layer thickness must be chosen to be correspondingly small and is typically in the range of 0.1 - 0.4 mm, in particular 0.2-0.3 mm.
