[0089] The bar compression distribution element holding rail 35 can comprise two parallel second flanges 47.

[0090] The two parallel second flanges 47 can be connected by a second web (not illustrated in the figures).

[0091] If the compression distribution element holding rail 35 is provided with integrated compression distribution elements 26 comprising lost molds 27, the lost molds 27 extends preferably, but not necessarily, in parallel between the two parallel second flanges 47 and beyond the two parallel second flanges 47.

[0092] The lost molds 27 comprises preferably, but not necessarily, a surrounding lateral wall 42 and a bottom 43.

[0093] The height of the surrounding lateral wall 42 of the lost molds 27 can be the same as the height of the two parallel second flanges 47.

[0094] It is also possible that the height of the surrounding lateral wall 42 of the lost molds 27 is more than twice the height of the two parallel second flanges 47 as illustrated in figures 26 and 27. This allows to cast and to make the compression distribution elements 26 higher and to make the compression distribution elements 26 capable of transferring shear force between the building part 2 and the projecting exterior part 3. This can make the provision of bars 9 in the form of shear bars extending through the elongated insulating body 4 unnecessarily, if the building element 1 shall be capable of transferring shear force between the building part 2 and the projecting exterior part 3.

[0095] Tension bands 31 can, as in the first embodiment illustrated in figures 1 to 3, be provided and configured to force the top rail structure 7 and the bottom rail structure 8 towards each other so that the elongated insulating body 4 and the bar holder rail(s) 10 and the possible compression distribution element holding rail(s) 35 are pressed between the top rail structure 7, the bottom rail structure 8 and the tension bands 31.

[0096] The tension bands 31 unifies the top rail structure 7, the bottom rail structure 8 and the elongated insulation body 4 and the bar holder rail(s) 10 and the possible compression distribution element holding rail(s) 35 together so that the top rail structure 7, the bottom rail structure 8 and the elongated insulation body 4 and the bar holder rail(s) 10 and the possible compression distribution element holding rail(s) 35 are connected with each other and acting as one system.

[0097] The tension bands 31 are preferably, but not necessarily, inflexible. The tension bands 31 can for example be tension straps provided with apertures, zip ties, cable ties, or the like which are preferably, but not necessarily, are made of polymer. The length of the tension bands 31 are preferably, but not necessarily, adjustable and/or selectable so that the elongated insulating body 4 can be properly pressed between the top rail structure 7 and the bottom rail structure 8 and the tension bands 31.

[0098] The tension bands 31 can circumvent the top rail structure 7, the bottom rail structure 8 and the elongated insulation body 4 or be arranged between the top rail structure 7 and the bottom rail structure 8.

[0099] It is possible that tension bands 31 are connected between the top rail structure 7 and the bottom rail structure 8 at the first side 5 of the elongated insulation body 4 and that tension bands 31 are connected between the top rail structure 7 and the bottom rail structure 8 at the second side 6 of the elongated insulation body 4. In such case, the top rail structure 7 can comprise first hooks 32, first loops or the like integrally provided with an outer surface of the top rail structure 7, and the tension bands 31 can be connected to the first hooks 32, first loops or the like. In such case, the bottom rail structure 8 can comprise second hooks 33, second loops or the like integrally provided with an outer surface of the bottom rail structure 8 and the tension bands 31 can be connected to the second hooks 33, second loops or the like.

[0100] It is also possible that tension bands 31 are at the first side 5 of the elongated insulation body 4 connected between a bar holder rail 10 or a compression distribution element holding rail 35 attached to the top rail structure 7 and a bar holder rail 10 or a compression distribution element holding rail 35 attached to the bottom rail structure 8 and that tension bands 31 are the second side 6 of the elongated insulation body 4 connected between a bar holder rail 10 or a compression distribution element holding rail 35 attached to the top rail structure 7 and or a bar holder rail 10 or a compression distribution element holding rail 35 attached to the bottom rail structure 8 at .In such case the bar holder rail 10 or the compression distribution element holding rail 35 attached to the top rail structure 7 can comprise first hooks 32, first loops or the like integrally provided at the bar holder rail 10 or at the compression distribution element holding rail 35 attached to the top rail structure 7, and the tension bands 31 can be connected to the first hooks 32, first loops or the like. In such case the bar holder rail 10 or the compression distribution element holding rail 35 attached to the bottom rail structure 8 can comprise second hooks 33, second loops or the like integrally provided at the bar holder rail 10 or at the compression distribution element holding rail 35 attached to the bottom rail structure 8, and the tension bands 31 can be connected to the second hooks 33, second loops or the like.

[0101] The elongated insulating body 4 can comprise several separate insulating parts 54 assembled together to form said elongated insulating body 4.

[0102] If the building element 1 comprises bars 9 which are shear bars, the shear bars can extend diagonally through the elongated insulating body 4 between adjacent separate insulating parts 54.

[0103] At least two of said several separate insulating parts 54 are preferably, but not necessarily, assembled together without using adhesive or the like. This makes it easier to manufacture the building element 1.

[0104] Two elongated separate insulating parts 54 of said several separate insulating parts 54 can be separated by an inclined plane 55.

[0105] The elongated insulating body 4 can also be in a single piece form as in the fifth embodiment of the building element illustrated in figures 29 to 32. If the building element 1 comprises bars 9 which are shear bars, the shear bars can extend diagonally through cuts 58 in the elongated insulating body 4 as in the fifth embodiment of the building element illustrated in figures 29 to 32.

[0106] It is apparent to a person skilled in the art that as technology advanced, the basic idea of the invention can be implemented in various ways. The invention and its embodiments are therefore not restricted to the above examples, but they may vary within the scope of the claims.
