A wall panel with a window aperture, comprising:
- a first plate, a second plate, ribs and cross members, two groups of a first thermal insulation layer, a second thermal insulation layer, thermal insulation elements and flexible links,
- the first plate and the second plate are made of concrete-containing material, wherein the first plate is provided with a first surface and a third surface, which surfaces are located on opposite sides of the first plate,
- the first surface and the third surface are arranged to have larger areas as compared to other surfaces of the first plate, each of the ribs and each of the cross members are configured as a bar, the second plate is provided with a second surface and a fourth surface, which surfaces are located on opposite sides of the second plate, the second surface and the fourth surface are configured to have larger areas compared to other surfaces of the second plate, the ribs and the cross members are located on the third surface of the first plate, the ribs and the cross members are configured to be integral with a part of the first plate, the ribs are disposed at a distance from one another substantially parallel to one another and perpendicular to the cross members, each first thermal insulation layer of one group is disposed on the third surface between the ribs and cross members, each first thermal insulation layer of the one group (11-1) of the two groups is closest to said ribs and sections of the cross members are located between said ribs, each of the groups of the first thermal insulation layer is disposed flush with the surfaces of the ribs and the cross members which are opposite to the first plate, the second thermal insulation layer is disposed on the first thermal insulation layer and also on the surfaces of the ribs and the cross members which are opposite to the first plate, the fourth surface of the second plate is disposed on the second thermal insulation layer, on two opposite sides of the window aperture which are parallel to the ribs and on one side of the window aperture which is parallel to the cross members, the second plate creates thrust lugs, the second plate and ribs are connected through the second thermal insulation layer by the flexible links,
- wherein between each rib closest to the window aperture and a thrust lug closest to said rib, there is disposed a first thermal insulation layer of the other group, between the cross member closest to the window aperture and the thrust lug closest thereto, there is disposed first thermal insulation layers of the other group, each thermal insulation element is disposed between the first plate and the second plate and covers the first thermal insulation layer and the second thermal insulation layer from the side of the window aperture, and wherein at least one thrust lug protrudes on each side of the window aperture with respect to the thermal insulation elements.
