Description

Field of the disclosure The present disclosure relates to a beam assembly for a slat wall. More specifically a beam assembly for forming a back-construction slat wall or a free-standing slat wall comprising a plurality of beam assemblies. Background Slat walls or slat screens have both an aesthetic character and a technical function. Slat walls or slat screens are for example positioned in front of windows or openings in buildings or houses in order to reduce the impact of the sun, rain and wind on the building or house. Especially for large openings or large glass surfaces, slat walls can have a significant impact in reducing a temperature build-up in buildings. Slat walls can either be classified as back-construction slat walls or as free-standing slat walls. With back-construction slat walls, the beams of the slat wall are positioned in front of a building or window and hence in the back side of the beams there is generally no free space as the back sides of the beams are positioned closely to the building or window. On the other hand, free-standing slat walls are defined as slat walls that have a free space in the front side and a free space in the back side of the beams forming the slat wall. Hence a free-standing slat wall can be construed as a wall formed by beams aligned along an alignment line and spaced from each other and wherein there is free space on both sides of the wall. A free-standing slat wall can for example be used to make a separation between two areas in a building or to close off large openings in buildings. For example in parking towers, slat walls can be used to cover large openings in the tower. In these configurations, there is free space on one side of the slat wall, i.e. the interior of the parking tower, and a free space on the other side of the slat wall, i.e. the exterior of the parking tower. In this example, the slat wall reduces the impact of the wind and the infiltration of water and it further prevents persons or objects to fall down from the parking tower. Slat walls used for applications involving building constructions have to fulfil severe fire regulations and generally, for most projects, only materials fulfilling a specific fire classification can be used. Therefore, the beams used for forming slat walls or screens are generally made of a metal such as for example aluminium. On the other hand, there is a need to use more ecological friendly materials as raw construction materials. In view of its low CO2 footprint, wood is a good example of an ecological friendly material that can be used for construction work. On the other hand, untreated wood can generally not attain the specific requirements in terms of fire regulations for construction work. Depending on the specific fire regulations applicable, untreated wood generally falls in a category of highly flammable material. Currently, wooden slat walls are therefore using beams that are impregnated with a fire retardant product. A drawback with treated wood is that impregnation needs to be repeated periodically which is expensive and time consuming. Further, the presence of the fire retardant product generally attracts water and stains can occur after a certain time. Further, the product used for impregnation is not always ecologically friendly. Document JP202106337A, not related to slat walls, discloses a laminated wooden beam wherein a steel reinforcing member is integrated in a groove formed in a surface of the wooden beam. Hence, there is room for improving beam assemblies for slat walls. Summary It is an object of the present disclosure to provide a beam assembly for a slat wall or slat screen that is ecologically friendly and that does not have the shortcomings discussed above. The present disclosure is defined in the appended independent claim 1. The dependent claims define advantageous embodiments. According to the invention , a beam assembly for forming a slat wall or screen is provided. The beam assembly comprises a beam elongating along a longitudinal axis from a base side to a top side of the beam opposite the base side. The beam further comprises a first lateral side and a second lateral side opposite the first lateral side, and wherein the first and second lateral sides are extending from the base side to the top side. The beam assembly is characterized in that it further comprises a first and a second metal profile attached to respectively the first lateral side and the second lateral side of the beam, and wherein the first and second metal profile are extending parallel with the longitudinal axis, and in that the first and the second lateral side comprises respectively a first and a second recess receiving respectively the first and second metal profile such that the first and second metal profiles are recessed into the lateral sides of the beam. Advantageously, by providing a first and a second metal profile attached to respectively the first lateral side and the second lateral side of the beam, a f
